Indications for Use
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.
Device Story
NGS is a stereotaxic medical device for dental implant surgery. Input: patient CT scan. Operation: surgeon uses planning software to place virtual implants; system provides physical, visual, and audible guidance during site preparation. Physical guidance: Guidance Arm grips dental drill, constraining motion to the surgical plan while allowing manual surgeon control. Visual guidance: 3D/2D real-time display of drill position relative to plan. Patient tracking: Patient Splint (attached to teeth) and Patient Tracker (mechanical feedback) relay movement data to software, which adjusts cutting angle/position in real-time to maintain accuracy. Used in dental clinics by surgeons. Benefits: prevents deviation from plan, avoids critical anatomical structures, maintains accuracy despite patient movement. Surgeon retains final clinical decision-making authority.
Clinical Evidence
No clinical data. Evidence consists of bench testing and simulated use validation. Testing included total system accuracy verification, end-user validation using typodonts, software/system verification (registration, boundary conditions, error injection, CT scan verification), and mechanical safety testing (Guidance Arm accuracy/repeatability, F/T sensor verification, patient motion tracking).

## Indications for Use:
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.
## Device Description:
The Neocis Guidance System (NGS) is a stereotaxic medical device that guides surgeons during dental implant surgery. The system allows the user to plan the surgery virtually in software using a CT scan of the patient, and the plan is used by a quidance system to provide physical, visual, and audible feedback to the surgeon during the implant site preparation.
{4}------------------------------------------------
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 quidance of the dental surgical instruments according to the pre-operative plan.
Physical quidance is provided via the Guidance Arm. The Guidance Arm grips a standard dental drill from the back end, allowing the surgeon to grip the drill as normal. The Guidance Arm does not move unless the surgeon applies a manual force to the drill. The Guidance Arm will constrain the surgeon to drill according to the prescribed surgical plan, preventing deviation. The surgeon is constantly in control of the drilling.
Visual guidance is provided by 3D graphics and 2D cross sections that indicate the position and orientation of the drill in relation to the pre-operative plan and scan. The visual feedback is updated in real-time so any relative motion between the dental handpiece and the patient properly update the visualization.
The patient tracking portion of the NGS is comprised of the Patient Splint and the Patient Tracker. The Patient Splint is attached to the contralateral side of the patient's mouth. The Patient Splint is placed on the patient prior to the CT scan. A fiducial array with fiducial markers is placed on the Patient Splint prior to the CT scan so the virtual plan can be related to the physical space of the system. The Patient Tracker is a mechanical feedback system that is connected to the Patient 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 and position to accommodate the patient movement, which will maintain the accuracy of the drill placement.
Several steps are required for calibration and measurement during the procedure. The drill is calibrated using the Calibration Drill Bit inserted into a precise position on the Patient Tracker. During the surgery, each drill bit must be measured with the Depth Gauge to determine the proper length of the bit. These measurements complete the loop so the entire NGS is accurate to the tip of the drill.
The NGS is a supporting device, providing additional information and guidance to the decision- making process during the surgical procedure. It is not intended to replace the surgeon's judqment. The final clinical decisions are the sole responsibility of the surgeon. The surgeon can at any time during the surgical procedure modify the planned implant positions. Under no circumstances does the device relieve the surgeon of his or her ultimate clinical responsibility.
The subject device is the same as the NGS cleared under K182776 (the predicate device), except for a change to the dental drill supplier and dental drill collar design. The dental handpiece and motor have received previous 510(k) clearance under K070084
{5}------------------------------------------------
#### and K030163.
The splint is a key component for patient tracking for the NGS. The patient tracking portion of the NGS is comprised of the Chairside Splint and the Patient Tracker. The Chairside Splint is attached to the contralateral side of the patient's mouth. The Chairside Splint is affixed to the patient's teeth using dental materials specified in the labeling. The Chairside Splint is placed on the patient prior to the CT scan. A fiducial array with fiducial markers is placed on the Chairside Splint prior to the CT scan so the virtual plan can be related to the physical space of the system. The Patient Tracker is a mechanical feedback system that is connected to the Patient Chairside 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 and position to accommodate the patient movement, which will maintain the accuracy of the drill placement.
## Comparison of Technological Characteristics:
This submission involves a modification to the dental drill supplier and to the dental drill collar design. Otherwise, all performance characteristics of the NGS are the same. The differences introduced by this modification are detailed in the table 1 below.
