Navident is a computerized dental navigational system intended to assist preoperative planning and to guide drilling in a patient jaw during implantation surgery, using pre-acquired CT scan of the jaw. The device is intended for use by a qualified dental surgeon in the treatment of partially or fully edentulous jaws.

Navident is an image-guided dental navigational system intended to assist with preoperative planning and real-time positioning of drilling tools during implantation surgery. In particular, Navident provides visual, real-time feedback on the location of the working tip of a dental handpiece. It shows the location and direction of the tip relative to a volumetric CT image of the patient's jaw registered to that anatomy, and, when available, relative to a path planned on that image. Navident is comprised of the following parts: The main system is comprised of a cart that carries a stereoscopic video camera and a laptop with pre-installed proprietary software. The Navident system also includes several types of accessories: Jaw motion Tracking Accessories, Dental Handpiece Tracking Accessories, Registration accessories, Calibrator. Navident's four core functions are: Model, Plan, Register, Guide.

The X-Guide® Surgical Navigation System is a computerized navigational system intended to provide assistance in both the preoperative planning phase and the intra-operative surgical phase of dental implantation procedures and/or endodontic access procedures.

The system provides software to preoperatively plan dental implantation procedures and/or endodontics access procedures and provides navigational guidance of the surgical instruments.

The device is intended for use for partially edentulous adult and geriatric patients who need dental implants as a part of their treatment plan. The device is also intended for endodontic access procedures (i.e., apicoectomies and/or access of calcified canals) where a CBCT is deemed appropriate as part of their treatment plan.

The X-Guide® Surgical Navigation System is a cart mounted mobile system utilizing video technology to track position and movement of a surgical instrument (Dental Hand-Piece) during surgical procedures.

The X-Guide® Surgical Navigation System consists of a Mobile Cart, equipped with an LCD Monitor, Boom Arm, Navigation Assembly, Keyboard, Mouse and an Electronics Enclosure.

The Electronics Enclosure contains the system power supplies, data processing hardware, and electronics control circuity for coordinating operation of the X-Guide® Surgical Navigation System.

A LCD Monitor, Keyboard, and Mouse serve as the main user interface for the surgeon. The Go-Button serves as an additional form of input by providing virtual buttons that a user can activate by touching them with the surgical instrument tip.

The Boom Arm allows the operator to manipulate the Navigation for optimal distance and alignment to patterns located with the surgical region (Navi-Zone) for tracking purposes.

The Navigation Assembly contains two cameras oriented in a stereo configuration, along with blue lighting the patterns and mitigating ambient lighting noise.

This electro-optical device is designed to improve dental surgical procedures by providing the surgeon with accurate surgical tool placement and guidance with respect to a surgical plan built upon Computed Tomographic (CT scan) data.

The implant process occurs in two stage 1 is the pre-planning of the surgical implantation procedure. The dental surgeon plans the surgical procedure in the X-Guide System Planning Software. A virtual implant is aligned location in the CT scan, allowing the dental surgeon to avoid interfering with critical anatomical structures during implant surgery. Once an implant has been optimally positioned, the plan is transferred to the X-Guide Surgical Navigation System in preparation for implant surgery.

In Stage 2 the system provides accurate guidance of the dental surgical instruments according to the pre-operative plan.

Here's a breakdown of the acceptance criteria and the study that proves the device meets them, based on the provided text:

Context: The FDA 510(k) submission (K211701) for the X-Guide® Surgical Navigation System is seeking to expand its indications for use to include endodontic access procedures, in addition to its existing clearance for dental implantation procedures. The core argument is that endodontic access procedures are technologically similar to drilling pilot holes for implants, and existing system performance (accuracy) is sufficient.

1. Table of Acceptance Criteria and Reported Device Performance:

The document doesn't explicitly state "acceptance criteria" in a numerical or target performance format for this specific submission's expanded indication. Instead, it relies on the existing performance characteristics of the predicate device (X-Guide® Surgical Navigation System, K192579) and demonstrates through comparative studies that this performance is better than freehand for the new indication.

The key performance characteristic cited is **Overall System Accuracy (RMS)
