Yomi Robotic System is a computerized robotic 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 robotic navigational guidance of the surgical instruments. The system can also be used for planning and performing guided bone reduction (also known as alveoplasty) of the mandible and/or maxilla. Yomi is intended for use in partially edentulous and fully edentulous adult patients who qualify for dental implants.

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

Yomi Robotic System is a dental stereotaxic instrument and a powered surgical device for bone cutting. Yomi Robotic System 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 Yomi Robotic System is intended for use in partially edentulous and fully edentulous adult patients who qualify for dental implants.

The Yomi Robotic System allows the user to plan the surgery virtually in YomiPlan, 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 for the system to provide physical, visual, and audible feedback to the surgeon during the implant site preparation. The Yomi robotic arm holds and guides a standard FDA-cleared third party powered bone cutting instrument.

The patient tracking portion of Yomi is comprised of linkages from the patient to Yomi, which include the Clamped Chairside Patient Splint (C-CPS) or YomiLink Bone (YLB), the Tracker End Effector (TEE) 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 prior to the presurgical CBCT scan. The EPS is placed using bone screws prior to the presurgical CBCT scan (appropriate local anesthesia is required).

The subject of this submission is to modify the design and reprocessing method for the Tracker End Effector (TEE) of the Yomi Robotic System. All other aspects of the Yomi Robotic System remain unchanged from prior clearances.

Here's an analysis of the acceptance criteria and study information based on the provided text, using the requested structure:

1. Table of Acceptance Criteria & Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

The document does not explicitly state the sample sizes used for the performance tests (Total System Accuracy, Kinematic Repeatability, Drill Jig Accuracy, Disinfection Validation, Material Testing, Mating Component Design Verification). It only indicates that these tests were "fully executed."

For the Usability Validation Testing for reprocessing instructions, the document mentions "dental clinician users," but the specific number (sample size) is not provided. The data provenance is implied to be through direct observation and feedback from these users.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

The document does not specify the number of experts or their qualifications for establishing ground truth for the performance tests. These tests appear to be engineering verification and validation tests rather than clinical studies requiring expert ground truth in the traditional sense.

For the Usability Validation Testing, it states that "dental clinician users" were involved, but their specific qualifications (e.g., years of experience, specialty) or the number of such users are not detailed.

4. Adjudication Method for the Test Set

The document does not mention any adjudication method (e.g., 2+1, 3+1) for any of the described tests. The tests appear to be objective verification and validation tests where outcomes are measured against predefined technical specifications or industry standards.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

No multi-reader multi-case (MRMC) comparative effectiveness study is mentioned in the provided text. The document focuses on performance testing related to design modifications and reprocessing.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

The Yomi Robotic System is described as a "computerized robotic navigational system intended to provide assistance in both the planning (pre-operative) and the surgical (intra-operative) phases of dental implantation surgery." This implies a human-in-the-loop system. The document does not describe any standalone performance studies where the algorithm or robotic system operates without human interaction or oversight for clinical decision-making or execution. The "Total System Accuracy Verification" would likely assess the machine's standalone accuracy within the system's design, but not as a replacement for human performance.

7. Type of Ground Truth Used

For the performance tests (accuracy, repeatability, drill jig accuracy, material, design), the ground truth would be based on engineering specifications, metrology standards, and validated test methods. For the disinfection validation, the ground truth is established by microbiological testing against industry standards (AAMI TIR12 and FDA Guidance). For the usability testing, the ground truth is likely based on user feedback and successful completion of critical tasks as defined by the usability protocol. No explicit mention of clinical outcomes data or pathology as ground truth is made, which aligns with the focus on design modifications and reprocessing rather than a new clinical application.

8. Sample Size for the Training Set

The document does not describe any machine learning or AI components that would require a "training set" in the traditional sense. The device is a robotic system providing navigational guidance. If any internal models or algorithms are used, the training data for those are not disclosed in this summary.

9. How the Ground Truth for the Training Set Was Established

Since no training set is mentioned (or implied for AI/ML purposes), this information is not provided.

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.

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, the Neocis Guidance System (NGS) (K161399) 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 system allows the user to plan the surgery virtually in our Neocis Planning Software Application installed on the NGS planning station or on a 3rd party PC (K191363). 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 FDA-cleared 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), 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 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
• Surgeon control

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.

Here's an analysis of the acceptance criteria and study information provided:

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.
