Accuracy of Dynamic Navigation for Dental Implant Placement-Model-Based Evaluation

Area of Science:

• Dentistry
• Medical Device Technology
• Surgical Navigation

Background:

• Accurate dental implant placement is crucial for successful outcomes.
• Existing static and dynamic guidance systems have varying degrees of accuracy.
• Freehand implant placement presents significant challenges in precision.

Purpose of the Study:

• To evaluate the accuracy of a novel dynamic navigation system for dental implant placement.
• To compare the system's accuracy in dentate and edentulous models.
• To benchmark performance against published data for static guidance, dynamic guidance, and freehand techniques.

Main Methods:

• Model-based investigation using a dynamic navigation system (X-Guide) with optical triangulation tracking.
• A single, experienced surgeon performed implant placements under clinical simulation.
• Post-operative cone-beam computed tomography (CBCT) scans were analyzed for deviations from the virtual plan.

Main Results:

• Angular accuracy was 0.89° ± 0.35° for dentate and 1.26° ± 0.66° for edentulous models.
• Three-dimensional positional accuracy was 0.38 ± 0.21 mm for dentate and 0.56 ± 0.17 mm for edentulous models.
• The system demonstrated high accuracy relative to the preoperative virtual plan.

Conclusions:

• The tested dynamic navigation system offers high accuracy for dental implant placement.
• The system's precision is suitable for both dentate and edentulous clinical scenarios.
• This technology represents a valuable advancement in guided dental surgery.
