The U-shaped tube (UT) registration method for dynamic navigation-assisted endodontic microsurgery (DN-EMS) is more accurate and efficient than the tooth cusp (TC) method. However, the UT method requires an additional registration device.
Area of Science:
- Endodontics
- Dental Microsurgery
- Medical Simulation
Background:
- Dynamic navigation-assisted endodontic microsurgery (DN-EMS) offers potential for improved precision in dental procedures.
- Accurate registration is crucial for the success of navigation-assisted surgery.
Purpose of the Study:
- To compare the accuracy and efficiency of two registration methods for DN-EMS: U-shaped tube (UT) and tooth cusp (TC).
Main Methods:
- Forty 3D-printed teeth were divided into two groups (n=20) for DN-EMS using either UT or TC registration.
- Accuracy was assessed via platform deviation, end deviation, angular deviation, and resection length deviation.
- Efficiency was measured by registration time; osteotomy volume was calculated using Mimics 21.0.
Main Results:
- The UT group demonstrated significantly higher accuracy in platform deviation, end deviation, and angular deviation compared to the TC group (P < .05).
- The UT group was significantly more efficient, requiring less registration time (P < .05).
- No significant differences in osteotomy volume were observed between the groups.
Conclusions:
- DN-EMS with UT registration is superior in accuracy and efficiency compared to the TC method in model-based simulations.
- The TC method presents a viable alternative for specific clinical scenarios where an additional registration device is not feasible.
