The system provides software to preoperatively plan dental implantation procedures and provides navigational guidance of the surgical instruments. The NGS is intended for use in partially edentulous and fully edentulous adult patients who qualify for dental implants.

Major components include: Monitor, Planning Station Laptop PC, Lift Column, Base Cart, Robotic Guide Arm, and Patient Tracker.

The system allows the user to plan the surgery virtually in Yomi Plan (K191363-cleared for use alone on third party PCs for preplanning). The operative plan is based on a cone beam computed tomography (CBCT) scan of the patient, which is used to create a 3-D model of the patient anatomy in our planning software. The plan is used by a guidance system to provide physical, visual, and audible feedback to the surgeon during the implant site preparation. The NGS robotic arm holds and guides a standard FDAcleared third party powered bone cutting instrument (K191605).

The patient tracking portion of the NGS is comprised of linkages from the patient to the NGS, which include the Chairside Patient Splint (CPS) (K173402) or Edentulous Patient Splint (EPS) (K200805), the End Effector (EE) and the Patient Tracker (PT).

The request is to describe the acceptance criteria and the study that proves the device meets the acceptance criteria for the Neocis Guidance System (NGS) with Yomi Plan v2.0.1.

Based on the provided text, the submission does not contain a study proving that the device meets specific performance acceptance criteria for its clinical function. Instead, it modifies an existing, previously cleared device (NGS with Yomi Plan v2.0) to allow continuous Wi-Fi activity and describes the testing conducted to ensure this modification maintains safety and effectiveness, primarily through software verification, wireless coexistence testing, and EMC testing.

Therefore, the following information is extracted and presented in relation to the modification and associated testing, rather than a clinical performance study with acceptance criteria for the device's primary function of dental implantation guidance.

The Neocis Guidance System (NGS) is a computerized navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery. The system provides software to preoperatively plan dental implantation procedures and provides navigational guidance of the surgical instruments. The NGS is intended for use in partially edentulous and fully edentulous adult patients who qualify for dental implants.

The Neocis Guidance System (NGS) (K161399) is a dental stereotaxic instrument (Product Code PLV) and a powered surgical device for bone cutting (21 CFR 872.4120). The Neocis Guidance System (NGS) is a computerized navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery. The system provides precise and accurate navigational guidance of surgical instruments, with regard to planning in dental implantation procedures. The system allows the user to plan the surgery virtually in software using a cone beam computed tomography (CBCT) scan of the patient, and the plan is used by a guidance system to provide physical, visual, and audible feedback to the surgeon during the implant site preparation. The holds and guides a standard FDA-cleared powered bone cutting instrument.

The implant process occurs in two phases. First, the dental surgeon plans the surgical procedure with the planning software. A virtual implant is placed at the desired location in the CT scan, allowing the dental surgeon to avoid interfering with critical anatomical structures during implant surgery. Second, when the implant plan is optimally positioned, the NGS provides accurate guidance of the dental surgical instruments according to the pre-operative plan. The NGS provides haptic feedback to the surgeon by constraining the motion of the bone cutting instrument to the plan. This allows the surgeon to feel resistance to attempts at motions that may deviate from the plan.

The patient tracking portion of the NGS is comprised of linkages from the NGS, which for partially edentulous patients include the Chairside Patient Splint (CPS) (K173402) or the Clamped Chairside Patient Splint (CCPS) (K202100), the End Effector (EE) and the Patient Tracker (PT). The CPS or CCPS is attached to the contralateral side of the patient's mouth over stable teeth. The CPS is placed on the patient using on-label dental materials (K182776) prior to the presurgical CBCT scan. A Fiducial Array (FA) with radio-opaque fiducial markers is placed on the splint prior to the CBCT scan so the virtual plan can be related to the physical space of the system using the markers. The PT is an electromechanical feedback system that is connected to the splint on the patient, which relays information to the control software in order to track patient movement. If patient movement occurs during the surgical procedure, the system will respond by altering the prescribed surgical cutting angle, position, and depth to accommodate the patient movement, which will maintain the accuracy of the osteotomy.

The subject of this submission is a design change to the sleeves in our Edentulous Patient Splint (EPS) (K200805). The EPS enables use of the NGS in fully edentulous patients. It is affixed to the anterior mandible or maxilla using standard bone screws. Like the CPS and CCPS, the EPS serves as rigid connection to the patient for robotic tracking of the patient during the procedure. The EPS is intended for use in partially edentulous and fully edentulous adult patients who qualify for dental implants.

The provided text discusses the Neocis Guidance System (NGS) with Edentulous Patient Splint (EPS) and a design change to its sleeves. However, it does not contain a detailed study proving the device meets acceptance criteria for performance, especially not in the context of diagnostic accuracy (e.g., sensitivity, specificity, AUC).

Instead, the document focuses on demonstrating substantial equivalence to a predicate device (Neocis Guidance System (NGS) with Patient Splints, K200805) after a design change to the EPS sleeves. The "Performance Testing" section lists various tests conducted, primarily related to the physical and biological aspects of the device, rather than a clinical performance study.

Therefore, many of the requested elements (like sample size for test/training sets, data provenance, number of experts for ground truth, adjudication method, MRMC studies, standalone performance, type of ground truth for training) are not available in the provided text for a clinical performance study.

Here's what can be extracted and inferred from the text, focusing on the design change and the tests mentioned:

Acceptance Criteria and Device Performance (Design Change Validation)

The document describes a design change to the sleeves within the Edentulous Patient Splint (EPS) component of the Neocis Guidance System (NGS). The acceptance criteria are implicitly related to ensuring this design change does not negatively impact the safety and effectiveness of the device, and that it remains substantially equivalent to the predicate.

1. Table of Acceptance Criteria and Reported Device Performance:

2. Sample size used for the test set and the data provenance:

• Sample Size: Not explicitly stated for performance tests like "EPS Weighted Deflection Test" or "Total System Accuracy". These are typically engineering verification tests, and the "sample size" would refer to the number of units tested.
• Data Provenance: Not specified for these engineering tests. "Sawbones®" is mentioned, indicating laboratory testing on synthetic bone models. This is not clinical data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Not applicable for the reported tests. The tests are engineering verification tests, not diagnostic accuracy studies requiring expert-established ground truth.

4. Adjudication method for the test set:

• Not applicable. See point 3.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

• No MRMC study was mentioned or conducted. The device is a surgical guidance system, not a diagnostic AI tool for human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

• Not explicitly described as a standalone algorithm performance study. The "Total System Accuracy" test would assess the device's accuracy in guiding the surgical instrument, which is its primary function (albeit with a human surgeon operating the instrument under guidance). The text focuses on the mechanical and system accuracy of the guidance mechanism itself, not a diagnostic algorithm.

7. The type of ground truth used:

• For mechanical tests: Engineering specifications, precision measurements, or established physical benchmarks are the "ground truth."
• For biological tests: Standards (e.g., ISO 10993) and established laboratory protocols define the "ground truth" for material properties and effects.

8. The sample size for the training set:

• Not applicable. The document does not describe the development or training of an AI algorithm in the context of a "training set" for diagnostic performance.

9. How the ground truth for the training set was established:

• Not applicable. See point 8.

Summary of Device Performance (from the document's conclusion):
The primary conclusion is that "The design changes to the EPS sleeves have been verified using well established methods. The new design is functionally the same as the predicate device. The subject device different questions of safety and effectiveness. Therefore, the subject device is substantially equivalent to the predicate." This implies that all the listed performance tests were successfully passed, ensuring that the modified device remains as safe and effective as its predecessor.

The NGS is intended for use in partially edentulous adult patients who qualify for dental implants.

When Yomi Plan software is used for preplanning on third party PCs, it is intended to perform the planning (pre-operative) phase of dental implantation surgery. Yomi Plan provides pre-operative planning for dental implantation procedures. The output of Yomi Plan is to be used with the Neocis Guidance System (NGS).

In terms of FDA regulations, the Neocis Guidance System (NGS) is a dental stereotaxic instrument (Product Code PLV) and a powered surgical device for bone cutting (21 CFR 872.4120).

In terms of previously FDA-cleared indications for use (K200805), the Neocis Guidance System (NGS) is a computerized navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery. The system provides software to preoperatively plan dental implantation procedures and provides navigational guidance of the surgical instruments.

The Patient Splint is attached to the contralateral side of the patient's mouth over stable teeth. The CPS is placed on the patient using on-label dental materials (K182776) prior to the presurgical CBCT scan. The EPS is placed using bone screws prior to the presurgical CBCT scan (appropriate local anesthesia is required). A Fiducial Array (FA) with radio-opaque fiducial markers is placed on the CPS prior to the CBCT scan so the virtual plan can be related to the physical space of the system using the markers. The PT is an electromechanical feedback system that is connected to the CPS on the patient, which relays information to the NGS in order to track patient movement. If patient movement occurs during the surgical procedure, the system will respond by altering the prescribed surgical cutting angle, position, and depth to accommodate the patient movement, which will maintain the accuracy of the osteotomy.

The implant process occurs in two phases: (1) The dental surgeon plans the surgical procedure with the planning software, on the day of surgery or sometime prior if a pre-operative CT scan was taken at an earlier visit. A virtual dental implant, selected from the dental implant library or using a generic model, both contained within our planning software, is placed at the desired location in the patient model. The software highlights critical anatomical structures to avoid, such as the inferior alveolar nerve. (2) When the dental implant plan is optimized, the NGS provides precise and accurate guidance of the dental surgical instruments according to the preoperative plan. The NGS robotic arm, which holds the surgical instrument, provides haptic feedback to the surgeon by constraining the motion of the bone cutting instrument to the plan. This allows the surgeon to feel resistance to attempts at motions that may deviate from the plan. The surgeon may modify the plan intraoperatively, if needed, has direct visualization of the patient anatomy, and is always in control of the surgical instrument.

Key safety features include:

• Emergency stop
• Safety pause
• Audio and visual queues
• Drill torque limits
• Full surgeon control and direct visualization of the surgical field

The Neocis Guidance System (NGS) with Yomi Plan v2.0 is a "catch-up" focused on the planning software and presenting changes made from v1.2 (K161399) to the current release v2.0 (wireless network capabilities, interface updates, etc.). The Neocis Guidance System (NGS) contains two software packages: (1) planning and (2) control. Each resides on a separate PC on the device: (1) planning station laptop PC and (2) control PC in the cart base. There are no changes to the control software or the NGS hardware in this submission. The use of TeamViewer has been implemented to access NGS systems that connected to external networks to examine system performance for postmarket.

The provided text describes a 510(k) premarket notification for the "Neocis Guidance System (NGS) with Yomi Plan v2.0". This submission primarily focuses on updates to the planning software (Yomi Plan v2.0) and the addition of wireless network capabilities. It does not include detailed acceptance criteria or a study proving device performance against those criteria in the way a clinical trial or algorithm validation study typically would. Instead, it relies on demonstrating substantial equivalence to previously cleared predicate devices through comparisons of technological characteristics, software verification and validation, and wireless coexistence testing.

Therefore, many of the requested details cannot be extracted from the provided document as they are not present.

Here's what can be inferred or stated based on the document:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not explicitly list "acceptance criteria" and "reported device performance" in a table format for a specific clinical or performance outcome. Instead, it focuses on demonstrating that the updated software (Yomi Plan v2.0) and new wireless features do not negatively impact the system's intended use and maintain substantial equivalence to predicate devices.

The "Performance Testing" section (Page 8) mentions that "Software V&V has been fully executed" and "Wireless Coexistence was testing according to the following". This implies that the acceptance criteria for these aspects would be compliance with the listed standards and successful execution of the validation activities.

2. Sample size used for the test set and the data provenance:

• Test Set Sample Size: Not explicitly stated for performance testing (e.g., how many cases or patients were used in end-user validation).
• Data Provenance: Not specified. The end-user validation was performed in a "simulated use environment." This suggests it was not a real-world patient study.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

• Not specified.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

• No MRMC comparative effectiveness study is mentioned. The device provides "navigational guidance" but is not primarily an AI-driven diagnostic or interpretative tool evaluated by human readers in this context. The focus is on the safety and effectiveness of the updated planning software and wireless functionality.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• The document implies that the "planning software" (Yomi Plan) is part of a "computerized navigational system" that provides "navigational guidance of the surgical instruments" to a surgeon. The system provides "haptic feedback to the surgeon" and emphasizes "Full surgeon control and direct visualization of the surgical field." This indicates a human-in-the-loop system. Standalone algorithm performance without human interaction is not the primary focus or explicitly described for the system's core function. The "planning" component could be considered "standalone" in its ability to create a plan, but its output is used by the guidance system in a human-controlled surgical procedure.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• For the software V&V, the "ground truth" would be adherence to software requirements, standards, and risk management principles. For wireless coexistence, it would be compliance with communication standards. For "End User Validation," it's ensuring the system "meet[s] the needs of the user," which implies functional correctness and usability in a simulated surgical context. Specific clinical ground truth based on patient outcomes or expert pathological review is not detailed in this submission as it's not a diagnostic AI device.

8. The sample size for the training set:

• The document describes a software update for a guidance system and does not mention machine learning or AI training sets. Therefore, this information is not applicable and not provided.

9. How the ground truth for the training set was established:

• Not applicable, as no training set for machine learning/AI is mentioned.

The subject device in this submission is the new Clamped Chairside Patient Splint (C-CPS). The C-CPS offers our users an alternative to acrylic-type dental material affixation. The subject device replaces the acrylic-type dental material locking mechanism of affixation with a clamplike mechanism of affixation using softer dental impression (registration) material, alignment slots, and an approximation screw. The clamping screw is not a bone screw, and it does not interact directly with the patient. The screw is positioned above the teeth inside the splint. The subject device is essentially a CPS (K173402) that has been bisected lengthwise with screw holes and alignment slots in each half to approximate the two halves around the patient's stable teeth. The dental impression material is placed inside the splint to form a tight conformational gripping surface between the splint and the teeth. The dental impression material conforms the shape of the patient's teeth to form a large gripping surface area. The C-CPS initial placement is like a dental impression tray. A torque-brake screwdriver with hex bit is used to tighten and loosen the screw. The proper C-CPS model (left/right or anterior/posterior) should be selected based upon the accommodation of the patient's anatomy and the intended surgical location.

The provided text describes a 510(k) premarket notification for the Neocis Guidance System (NGS) with Clamped Chairside Patient Splint (C-CPS). The submission aims to demonstrate substantial equivalence to a predicate device, the NGS with Chairside Splint (K173402), by introducing a new clamping mechanism for the patient splint.

The patient tracking portion of the NGS is comprised of linkages from the NGS, which include the Chairside Patient Splint (CPS) (K173402), the End Effector (EE) and the Patient Tracker (PT). The Patient Splint is attached to the contralateral side of the patient's mouth over stable teeth. The CPS is placed on the patient using on-label dental materials (K182776) prior to the presurgical CBCT scan. A Fiducial Array (FA) with radio-opaque fiducial markers is placed on the CPS prior to the CBCT scan so the virtual plan can be related to the physical space of the system using the markers. The PT is an electromechanical feedback system that is connected to the CPS on the patient, which relays information to the control software in order to track patient movement. If patient movement occurs during the surgical procedure, the system will respond by altering the prescribed surgical cutting angle, position, and depth to accommodate the patient movement, which will maintain the accuracy of the osteotomy.

The subject of this submission is our Edentulous Patient Splint (EPS). The EPS is affixed to the anterior mandible or maxilla using standard bone screws. Like the CPS, the EPS serves as rigid connection to the patient for robotic tracking of the patient during the procedure. The EPS is intended for use in partially edentulous and fully edentulous adult patients.

Here's a summary of the acceptance criteria and study information for the Neocis Guidance System (NGS) with Patient Splints, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document primarily focuses on demonstrating substantial equivalence to a predicate device (X-Guide Surgical Navigation System, K150222) rather than defining absolute acceptance criteria for novel performance claims. However, specific accuracy metrics are listed and compared.

Ask a specific question about this device

The Neocis Guidance System (NGS) is a computerized navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery. The system provides software to preoperatively plan dental implantation procedures and provides navigational guidance of the surgical instruments.

The Neocis Guidance System (NGS) (K161399) is a dental stereotaxic instrument (Product Code PLV) and a powered surgical device for bone cutting (21 CFR 872.4120). The Neocis Guidance System (NGS) is a computerized navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery. The system provides accurate navigational guidance of surgical instruments, with regard to pre-operative planning in dental implantation procedures. The system allows the user to plan the surgery virtually in software using a cone beam computed tomography (CBCT) scan of the patient, and the plan is used by a guidance system to provide physical, visual, and audible feedback to the surgeon during the implant site preparation. The holds and guides a standard FDA-cleared powered bone cutting instrument.

The implant process occurs in two phases. First, the dental surgeon plans the surgical procedure with the planning software. A virtual implant is placed at the desired location in the CT scan, allowing the dental surgeon to avoid interfering with critical anatomical structures during implant surgery. Second, when the implant plan is optimally positioned, the NGS provides accurate guidance of the dental surgical instruments according to the pre-operative plan. The NGS provides haptic feedback to the surgeon by constraining the motion of the bone cutting instrument to the plan. This allows the surgeon to feel resistance to attempts at motions that may deviate from the plan.

The patient tracking portion of the NGS is comprised of linkages from the patient to the NGS, which include the Chairside Patient Splint (CPS) (K173402), the End Effector (EE) and the Patient Tracker (PT). The Patient Splint is attached to the contralateral side of the patient's mouth over stable teeth. The CPS is placed on the patient using on-label dental materials (K182776) prior to the presurgical CBCT scan. A Fiducial Array (FA) with radio-opaque fiducial markers is placed on the CPS prior to the CBCT scan so the virtual plan can be related to the physical space of the system using the markers. The PT is an electromechanical feedback system that is connected to the CPS on the patient, which relays information to the control software in order to track patient movement. If patient movement occurs during the surgical procedure, the system will respond by altering the prescribed surgical cutting angle, position, and depth to accommodate the patient movement, which will maintain the accuracy of the osteotomy.

The subject device is a design variation of the predicate CPS (K173402). The portion of the splint that attaches to the patient now contains the fiducial markers. We are calling the subject device, the Fiducial Array Splint (FAS). This provides an alternative workflow in which the FA is not needed. These are the only changes in this submission. The NGS is otherwise the same as the cleared device (K161399). The indications for use and contraindications for the subject and predicate devices are the same.

Since the fiducial markers are on the portion of the splint that is affixed using dental material, we do have to limit the use of cleared dental materials (K182776) to those that are not radioopaque:

• 3M ESPE ProTemp Plus
• Alike
• Traid C&B Material (UV light curable)

The other dental materials cleared for use with the CPS cannot be used with the FAS.

Since the FAS does need the FA, we can use the FAS in CBCT scanners with smaller scan volumes and standard chin rests.

The Neocis Guidance System (NGS) with Fiducial Array Splint (FAS) is a computerized navigational system for dental implantation surgery. This 510(k) submission (K200348) describes a design variation to the patient tracking portion of the NGS, specifically the Fiducial Array Splint (FAS). The primary change is the integration of fiducial markers directly into the splint, eliminating the need for a separate Fiducial Array (FA).

Acceptance Criteria and Reported Device Performance

The provided document does not explicitly present a table of acceptance criteria with corresponding reported device performance metrics in numerical terms. Instead, it states that "Our performance testing demonstrates substantially equivalent performance of the subject device as compared to the predicate device." The "SE Analysis" column in Table 1 generally indicates "Identical," "Additional radio-transparent dental materials from reference device K182776," "Fiducial beads relocated to the FAS," and "Simpler interface, less parts." These are characteristic-level comparisons rather than quantitative performance metrics against specific acceptance criteria.

The document indicates that additional Neocis Performance Testing was conducted, including:

1. Bite force testing on fiducial markers
2. Cut removal
3. Loaded splint deflection testing using 2x PT weight
4. Simulated clinical use: end user validation on a typodont
5. Fiducial marker registration
6. Fiducial marker single use autoclave test
7. Total system accuracy testing

While these tests were performed to demonstrate substantial equivalence, the specific quantitative acceptance criteria for each test and the corresponding performance results are not detailed in this document. The conclusion states that performance testing "demonstrates substantially equivalent performance," implying that any defined acceptance criteria for these tests were met.

Study Details

The provided document describes a validation study for the newly designed Fiducial Array Splint (FAS) in comparison to the predicate Chairside Patient Splint (CPS) (K173402).

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not explicitly stated in terms of number of patients or experimental runs for each performance test. The document mentions "Simulated clinical use: end user validation on a typodont," which indicates a phantom-based testing approach.
   • Data Provenance: The study was conducted by Neocis Inc. The document does not specify the country of origin for the data or whether the study was retrospective or prospective, but given it's an end user validation on a typodont, it's a prospective, in-house validation.

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not explicitly stated. The "Simulated clinical use: end user validation on a typodont" implies that dental professionals would be involved in using the device and evaluating its performance, but the number and qualifications of these "end users" are not detailed.

3. Adjudication method for the test set: Not explicitly stated.

4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable. This device is a Guidance System for surgical procedures, not an AI-assisted diagnostic or interpretive tool where "human readers" or "cases" in the MRMC sense would typically apply. The focus is on the accuracy and safety of surgical instrument guidance.

5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: The "Total system accuracy testing" and other performance tests likely involved assessing the device's accuracy and functionality in a simulated environment, which could be considered standalone testing of the underlying guidance system's physical and software components. However, the "Simulated clinical use: end user validation" implies human-in-the-loop testing as well.

6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): For performance tests on a typodont model, the ground truth would typically be established by precise measurements of the planned versus actual implant trajectory/osteotomy, using high-precision measurement tools (e.g., CMM, optical tracking systems) to determine deviations from the pre-planned positions. This is a form of engineering measurement against a defined plan rather than expert consensus on a diagnosis or pathology.

7. The sample size for the training set: Not applicable. This document describes the validation of a physical medical device and its associated software for surgical guidance, not a machine learning algorithm that requires a "training set" for model development.

8. How the ground truth for the training set was established: Not applicable, as there is no mention of an AI model requiring a training set in this context.

The Neocis Guidance System (NGS) is a computerized navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery. The system provides software to preoperatively plan dental implantation procedures and provides navigational guidance of the surgical instruments.

The Neocis Guidance System (NGS) is a stereotaxic medical device that guides surgeons during dental implant surgery. The system allows the user to plan the surgery virtually in software using a CT scan of the patient, and the plan is used by a quidance system to provide physical, visual, and audible feedback to the surgeon during the implant site preparation.

The implant process occurs in two phases. First, the dental surgeon plans the surgical procedure with the planning software. A virtual implant is placed at the desired location in the CT scan, allowing the dental surgeon to avoid interfering with critical anatomical structures during implant surgery. Second, when the implant plan is optimally positioned, the NGS provides accurate quidance of the dental surgical instruments according to the pre-operative plan.

Physical quidance is provided via the Guidance Arm. The Guidance Arm grips a standard dental drill from the back end, allowing the surgeon to grip the drill as normal. The Guidance Arm does not move unless the surgeon applies a manual force to the drill. The Guidance Arm will constrain the surgeon to drill according to the prescribed surgical plan, preventing deviation. The surgeon is constantly in control of the drilling.

Visual guidance is provided by 3D graphics and 2D cross sections that indicate the position and orientation of the drill in relation to the pre-operative plan and scan. The visual feedback is updated in real-time so any relative motion between the dental handpiece and the patient properly update the visualization.

The patient tracking portion of the NGS is comprised of the Patient Splint and the Patient Tracker. The Patient Splint is attached to the contralateral side of the patient's mouth. The Patient Splint is placed on the patient prior to the CT scan. A fiducial array with fiducial markers is placed on the Patient Splint prior to the CT scan so the virtual plan can be related to the physical space of the system. The Patient Tracker is a mechanical feedback system that is connected to the Patient Splint on the patient, which relays information to the control software in order to track patient movement. If patient movement occurs during the surgical procedure, the system will respond by altering the prescribed surgical cutting angle and position to accommodate the patient movement, which will maintain the accuracy of the drill placement.

Several steps are required for calibration and measurement during the procedure. The drill is calibrated using the Calibration Drill Bit inserted into a precise position on the Patient Tracker. During the surgery, each drill bit must be measured with the Depth Gauge to determine the proper length of the bit. These measurements complete the loop so the entire NGS is accurate to the tip of the drill.

The NGS is a supporting device, providing additional information and guidance to the decision- making process during the surgical procedure. It is not intended to replace the surgeon's judqment. The final clinical decisions are the sole responsibility of the surgeon. The surgeon can at any time during the surgical procedure modify the planned implant positions. Under no circumstances does the device relieve the surgeon of his or her ultimate clinical responsibility.

The subject device is the same as the NGS cleared under K182776 (the predicate device), except for a change to the dental drill supplier and dental drill collar design. The dental handpiece and motor have received previous 510(k) clearance under K070084 and K030163.

The splint is a key component for patient tracking for the NGS. The patient tracking portion of the NGS is comprised of the Chairside Splint and the Patient Tracker. The Chairside Splint is attached to the contralateral side of the patient's mouth. The Chairside Splint is affixed to the patient's teeth using dental materials specified in the labeling. The Chairside Splint is placed on the patient prior to the CT scan. A fiducial array with fiducial markers is placed on the Chairside Splint prior to the CT scan so the virtual plan can be related to the physical space of the system. The Patient Tracker is a mechanical feedback system that is connected to the Patient Chairside on the patient, which relays information to the control software in order to track patient movement. If patient movement occurs during the surgical procedure, the system will respond by altering the prescribed surgical cutting angle and position to accommodate the patient movement, which will maintain the accuracy of the drill placement.

The provided text describes information about the Neocis Guidance System (NGS), a computerized navigational system for dental implantation surgery. However, the document (a 510(k) premarket notification) primarily focuses on demonstrating substantial equivalence to a predicate device due to a change in dental drill supplier and collar design, rather than proving the device meets new acceptance criteria established for this specific submission.

Therefore, the information regarding acceptance criteria and study details is largely drawn from previous clearances (K173402 and K161399) as the current submission leverages prior performance testing.

Here's a breakdown of the requested information based on the provided text:

1. A table of acceptance criteria and the reported device performance

The document doesn't explicitly define "acceptance criteria" presented as a single, consolidated list with corresponding performance for the current submission (K191605). Instead, it refers to the performance characteristics of the device, which serve as criteria for substantial equivalence to the predicate. The "Prior Performance Testing" sections (K173402 and K161399) detail various verification and validation activities.

For this submission, the comparison table (Table 1) between the subject device and the predicate device outlines several technical characteristics. The implicit acceptance criterion for these is "no difference" compared to the predicate, as highlighted in the "Comments" column.
