Accuracy of a Novel Trace-Registration Method for Dynamic Navigation Surgery.
Summary
Trace Registration (TR) offers accurate dynamic navigation for dental implant surgery, eliminating the need for traditional stents. This validated protocol shows precision comparable to existing guided methods.
Area of Science:
- Dental Implantology
- Surgical Navigation Technologies
Background:
- Traditional implant placement often relies on thermoplastic stents for guidance.
- Dynamic navigation systems offer potential for improved accuracy and efficiency.
- Trace Registration (TR) is a novel technology for dynamic navigation in implant surgery.
Purpose of the Study:
- To validate the accuracy of the Trace Registration (TR) protocol for dynamically guided implant surgery.
- To compare the accuracy of TR with traditional and statically guided implant placement methods.
Main Methods:
- A retrospective, observational, in vivo study design was employed.
- Dynamic navigation using the TR protocol was utilized for implant placement.
- Accuracy was assessed by superimposing preoperative and postoperative cone beam computed tomography (CBCT) scans.
Main Results:
- A total of 136 implants were placed in 59 partially edentulous arches.
- Mean deviations were 0.67 mm (coronal), 0.9 mm (apical), and 0.55 mm (depth).
- Mean angular discrepancy was 2.50 degrees, with improved accuracy noted when tracing 5-6 teeth.
Conclusions:
- Trace Registration (TR) provides accurate results for dynamically guided implant surgery.
- The TR protocol demonstrates accuracy comparable to traditional registration and static guidance methods.
- Tracing a larger number of teeth (5-6) may enhance the precision of TR.
