Summary
Cone-beam computed tomography (CT)-guided implant surgery demonstrates accuracy in implant placement. This study evaluated angular and distance errors, finding minimal deviations, suggesting clinical viability for CT-assisted dental implantology.
Area of Science:
- Dental Implantology
- Surgical Navigation
- Medical Imaging
Background:
- Cone-beam computed tomography (CT)-assisted surgical templates enhance predictability in dental implant placement by enabling in-surgery planning.
- Assessing the accuracy of CT-guided surgery is crucial for reliable outcomes.
Purpose of the Study:
- To evaluate the accuracy of computer-guided implant surgery by comparing planned and placed implant positions.
- To quantify angular and distance errors in CT-guided implant placement.
Main Methods:
- Computer-guided implant surgery was performed on five patients, involving 19 implants.
- Data fusion of pre- and post-operative imaging was used to analyze differences.
- Angular and distance errors (shoulder/apex) were calculated to assess accuracy.
Main Results:
- The mean angular error between planned and placed implants was 3.84° ± 1.49°.
- Mean distance errors at the implant neck were 0.45 ± 0.48 mm horizontally and 0.63 ± 0.51 mm vertically.
- Mean distance errors at the implant apex were 0.70 ± 0.63 mm horizontally and 0.64 ± 0.57 mm vertically.
Conclusions:
- CT-guided implant surgery shows promising accuracy for clinical application.
- Further improvements are needed for patient mouth opening limitations, surgical guide preparation, and fixation methods.
