Yomi 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. 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.
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.
Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided text:

§ 872.4120 Bone cutting instrument and accessories.
(a)
Identification. A bone cutting instrument and accessories is a metal device intended for use in reconstructive oral surgery to drill or cut into the upper or lower jaw and may be used to prepare bone to insert a wire, pin, or screw. The device includes the manual bone drill and wire driver, powered bone drill, rotary bone cutting handpiece, and AC-powered bone saw.(b)
