Device Description
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 the 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 Patient Splint (YomiLink Teeth or YomiLink Bone), Tracker End Effector (TEE), and the Patient Tracker (PT). In cases where YomiLink Teeth is utilized, it is attached to the contralateral side of the patient's mouth over stable teeth using on-label dental materials prior to the presurgical CBCT scan. In cases where YomiLink Bone is utilized, it is placed using bone screws prior to the presurgical CBCT scan (appropriate local anesthesia is required), or after the scan when using the subject YomiLink Arch device.
The subject of this submission is to introduce new accessories, the YomiLink Arch and Probing Bit. The YomiLink Arch allows for CBCT scan acquisition prior to YomiLink Bone placement and enables guided YomiLink Bone placement. This submission also introduces an update to the system planning software to enable use of the YomiLink Arch (YLA).
Following attachment of YomiLink Bone (YLB) to the patient, probing of the YLA is performed utilizing the YLA Probing Bit to transfer registration in the software from YLA to YLB and allow for tracking of the YLB throughout the remaining surgical procedure. The YLA Probing Bit is available in straight and contra-angle configurations corresponding to the handpiece to which they are attached.
All other aspects of the Yomi Robotic System remain unchanged from prior clearances.

Device Description
The subject of this submission is YomiPlan Go, a feature of the Yomi Robotic System which enables the use of the system without the uploading of a preoperative CT scan. The dynamic planning feature in K202264 requires a pre-operative CT scan for use. This submission includes a new workflow called YomiPlan Go and provides instructions on how to use this feature without the need of uploading a CT scan to the Yomi system. This planning involves placing the robotic arm drill tip to the point where an osteotomy is to be performed i.e., the surgeon performs planning with their direct visualization of the anatomy and with the use of the robotic arm to select where the osteotomy is to be performed. YomiPlan Go gives surgeons the ability to perform an osteotomy under robotic guidance at the point that the surgeon selects on the patient's anatomy. The selected point, axis, and trajectory are maintained by the robotic arm while the surgeon performs the osteotomy.

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.
Device Description
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 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

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 NGS is intended for use in partially edentulous and fully edentulous adult patients who qualify for dental implants.
Device Description
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 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 can be used for flapless dental implant procedures, which is a type of minimally invasive surgical approach. The NGS provides haptic feedback to the surgeon by constraining 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 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.
