A new inertial navigation system for guiding implant placement. An in-vitro proof-of-concept study

Area of Science:

• Dental Implantology
• Surgical Navigation Technologies
• Biomedical Engineering

Background:

• Standard stereolithographic templates are commonly used for dental implant placement.
• Advanced navigation systems offer potential improvements in precision and efficiency for surgical procedures.

Purpose of the Study:

• To evaluate a novel inertial navigation system for guiding dental implant placement.
• To compare the accuracy of this new system against traditional stereolithographic template guidance.

Main Methods:

• An inertial navigation system using a 9-axis sensor was integrated with a surgical handpiece.
• Sixty dental implants were placed in jaw models by experienced and non-experienced operators.
• Comparison of planned vs. actual implant positions using pre- and postoperative CT scans and deviation analysis.

Main Results:

• No significant differences in angular deviation were found between the inertial navigation group and the stereolithographic template group.
• Both experienced and non-experienced operators achieved comparable results with the new system.
• The inertial navigation system demonstrated potential as a viable tool for dental implant surgery.

Conclusions:

• Surgical navigation utilizing inertial measurement units (IMUs) is a promising approach for dental implant placement.
• The new system's performance is comparable to current standard methods, indicating its potential clinical utility.
• Additional studies are required to fully validate and implement this technology in clinical practice.
