Intended Use
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 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. Yomi Plan provides pre-operative planning for dental implantation procedures using the Yomi Robotic System. The output of Yomi Plan is to be used with the Yomi Robotic System.
Device Description
In terms of FDA regulations, the Yomi Robotic System is a dental stereotaxic instrument (Product Code PLV) and a powered surgical device for bone cutting (21 CFR 872.4120). In terms of previously FDAcleared indications for use (K210711), the 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 System allows the user to plan the surgery virtually in Yomi Plan, 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 FDAcleared third party powered bone cutting instrument. The patient tracking portion of Yomi is comprised of linkages from the patient to Yomi, which include the Chairside Patient Splint (CPS) or Edentulous Patient Splint (EPS), 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 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 introducing a feature to allow the system to be used for planning and performing guided bone reduction (also known as alveoplasty). The bone reduction feature is intended for use during dental implant procedures to flatten the surface of the bone intended for dental implant placement. The device is used with compatible bone cutting tool secured to the guidance arm for the bone reduction. The bone reduction feature is intended to be performed on full arch or partially edentulous patients. During preoperative planning, the surgeon identifies the area of the bone to be reduced. Real-time visualization of the bone reduction is visualized on the graphic user interface. The guidance arm constrains the movement of the cutting tool to the planned location, boundaries, and depth. After the bone reduction, the implant procedure continues with the Yomi Robotic System.
More Information

No
The summary describes a robotic surgical navigation system that uses pre-operative planning based on CBCT scans and provides physical, visual, and audible guidance during surgery. It does not mention or describe any components or functionalities that explicitly utilize AI or ML algorithms for tasks like image analysis, decision support, or adaptive control. The system appears to be based on pre-programmed navigation and guidance rather than learning or intelligent processing.

No
The device is a navigational system and robotic arm that assists surgeons during dental implantation and bone reduction procedures by guiding surgical instruments. It does not directly treat or cure a disease or condition.

No

Explanation: The device 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, and for guided bone reduction. Its function is to guide surgical instruments and assist in performing procedures, not to diagnose medical conditions or diseases.

No

The device description explicitly states it is a "computerized robotic navigational system" and includes physical components like a robotic arm, patient tracking linkages (splints, end effector, patient tracker), and guides a bone cutting instrument. While it includes software for planning, it is not solely software.

Based on the provided text, the Yomi Robotic System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices used to examine specimens, such as blood, urine, or tissue, taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Yomi's Function: The Yomi Robotic System is a surgical guidance system. It uses imaging data (CBCT scans) to plan and guide surgical procedures (dental implant placement and bone reduction) directly on the patient's body. It does not analyze samples taken from the body.
  • Device Classification: The text explicitly states the Yomi Robotic System is classified as a dental stereotaxic instrument and a powered surgical device for bone cutting. These classifications fall under surgical and dental device categories, not IVD.

Therefore, the Yomi Robotic System is a surgical device, not an IVD.

Image /page/4/Picture/0 description: The image shows the logo for Neocis. The logo consists of the word "neocis" in a sans-serif font, with the letters in a golden color. Above the word is a horizontal gray line that extends from the left of the "n" to the right of the "s". A vertical gray line intersects the horizontal line above the "o", forming a cross shape with a small circle at the intersection.

The Yomi System allows the user to plan the surgery virtually in Yomi Plan, 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 FDAcleared third party powered bone cutting instrument.

The patient tracking portion of Yomi is comprised of linkages from the patient to Yomi, which include the Chairside Patient Splint (CPS) or Edentulous Patient Splint (EPS), 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 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 introducing a feature to allow the system to be used for planning and performing guided bone reduction (also known as alveoplasty). The bone reduction feature is intended for use during dental implant procedures to flatten the surface of the bone intended for dental implant placement. The device is used with compatible bone cutting tool secured to the guidance arm for the bone reduction. The bone reduction feature is intended to be performed on full arch or partially edentulous patients. During preoperative planning, the surgeon identifies the area of the bone to be reduced. Real-time visualization of the bone reduction is visualized on the graphic user interface. The guidance arm constrains the movement of the cutting tool to the planned location, boundaries, and depth. After the bone reduction, the implant procedure continues with the Yomi Robotic System.

VI. Comparison of Technological Characteristics

The following Table 1 provides a summary of the subject Yomi System features compared to the predicate device, Neocis Guidance System (NGS) with Yomi Plan v2.0.1 (K210711), and a reference device, Mako Partial Knee Application (K142530). The MAKO device was chosen as the reference device since the visualization method during bone removal with the MAKO system for PKA is essentially the same as the subject device. Although the indications for use are different, the implementation of the visualization of the bone removal process is equivalent with both, the reference device as well as the predicate device.
