Implant Placement Accuracy Using Dynamic Navigation.

Area of Science:

• Dentistry
• Surgical Technology
• Medical Imaging

Background:

• Computer-assisted surgery is evolving for dental implantology.
• Dynamic navigation offers real-time guidance during implant placement.
• Assessing accuracy is crucial for clinical adoption of new surgical technologies.

Purpose of the Study:

• To evaluate the platform and angle accuracy of dental implants placed with dynamic navigation.
• To compare dynamic navigation accuracy against static guides and freehand methods.
• To investigate the learning curve associated with dynamic navigation for implant surgery.

Main Methods:

• Prospective study involving three surgeons using a dynamic navigation system (X-Guide).
• Implant placement in the mandible and maxilla guided by virtual plans.
• Post-operative cone beam CT scans used to measure deviations from the virtual plan.

Main Results:

• Dynamic navigation accuracy was comparable to static tooth-borne guides.
• Dynamic navigation demonstrated superior accuracy compared to freehand implant placement.
• Surgeons achieved similar accuracy levels after a learning curve, with proficiency by the 20th procedure.

Conclusions:

• Dynamic navigation provides accurate dental implant placement, on par with static guides.
• This computer-assisted surgery method is an improvement over freehand techniques.
• A learning curve exists, but proficiency is attainable with experience.
