Accuracy of Dental Implant Placement Using Dynamic Navigation With Different Optical Tracking Systems: An In Vitro...

Area of Science:

• Dental Implantology
• Surgical Navigation
• Optical Tracking Technologies

Background:

• Dynamic navigation systems enhance precision in dental implant placement.
• Investigating the impact of different optical tracking technologies on navigation accuracy is crucial.

Purpose of the Study:

• To compare the accuracy of dynamic navigation for implant placement using active infrared (AI), passive infrared (PI), and passive blue light (PB) optical tracking.
• The study tested the hypothesis that no significant difference exists between these three optical tracking technologies.

Main Methods:

• Three surgeons performed implant placements on 90 mandible models using AI, PI, and PB systems.
• Implants were placed at two sites per model: mandibular central incisors and first molars.
• Accuracy was assessed by superimposing planned and placed implant positions.

Main Results:

• Mean deviations across all implants were 0.82 mm (coronal), 0.92 mm (apical), and 1.56° (axial).
• Significant differences in accuracy were observed between PB and AI/PI systems for both central incisors and first molars.
• PB system showed statistically significant improvements over AI and PI systems.

Conclusions:

• The passive blue light (PB) optical tracking system offers superior accuracy for dynamic navigation in implant placement compared to AI and PI systems.
• Active infrared (AI) and passive infrared (PI) systems demonstrated comparable accuracy.
• All evaluated optical tracking systems provide sufficient accuracy for in vitro dynamic navigation applications.
