Implant position accuracy using dynamic computer-assisted implant surgery (CAIS) combined with augmented reality:...

Area of Science:

• Dental Implantology
• Surgical Navigation Technology
• Augmented Reality Applications

Background:

• Computer-assisted implant surgery (CAIS) enhances precision in dental implant placement.
• Dynamic CAIS systems offer real-time visualization of surgical instruments and patient positioning.
• Augmented reality (AR) technology presents potential for overlaying digital information in surgical fields.

Purpose of the Study:

• To compare the accuracy of dental implant positioning using dynamic CAIS with and without AR glasses.
• To evaluate the clinical efficacy of AR glasses in augmenting dynamic CAIS for implant surgery.

Main Methods:

• A randomized clinical study involving 20 patients requiring single dental implants.
• Patients were divided into two groups: dynamic CAIS with AR glasses (n=10) and dynamic CAIS without AR glasses (n=10).
• Three-dimensional deviations (platform, apex, angular) were measured and statistically analyzed.

Main Results:

• The AR glasses group showed mean 3D angular deviations of 1.47° ± 1.01°, compared to 2.42° ± 0.76° in the non-AR group.
• Mean 3D entry point deviations were 0.75 ± 0.45 mm (AR) vs. 1.11 ± 0.44 mm (non-AR).
• Mean 3D apical deviations were 0.87 ± 0.45 mm (AR) vs. 1.18 ± 0.50 mm (non-AR), with no statistically significant differences between groups.

Conclusions:

• Dynamic CAIS with AR glasses demonstrated similar accuracy in single dental implant placement compared to dynamic CAIS alone.
• The integration of AR glasses did not yield a statistically significant improvement in implant position accuracy in this study.
• Further research may explore specific scenarios or advanced AR features for potential benefits in CAIS.
