Summary
Full guided implant surgery accuracy is comparable to half-guided implant surgery. This study found no statistically significant difference in implant placement accuracy between the two methods.
Area of Science:
- Dental Implantology
- Surgical Accuracy
- Guided Surgery
Background:
- The accuracy benefits of full guided implant surgery over half-guided techniques remain unproven.
- Guided implant surgery utilizes templates for precise cavity preparation and implant insertion.
Purpose of the Study:
- To compare the accuracy of full guided implant surgery versus half-guided implant surgery.
- To evaluate deviations in implant placement at the base and tip.
Main Methods:
- 38 implants were virtually planned and inserted into five human cadaver jaws.
- Cavities were prepared using template-guided drilling.
- Implants were randomly placed using either free-handed (half-guided) or template-guided (full guided) methods.
- Postoperative cone beam computed tomography (CBCT) and image fusion were used to determine deviations.
Main Results:
- Mean deviation at implant bases was 0.72 mm and at implant tips was 0.46 mm.
- Full guided surgery showed slightly higher accuracy (mean tip: 1.54 mm, mean base: 1.52 mm) than half-guided (mean tip: 1.84 mm, mean base: 1.56 mm).
- The observed differences in accuracy between the two methods were not statistically significant.
Conclusions:
- Half-guided implant surgery demonstrates comparable accuracy to full guided implant surgery.
- The accuracy of implant placement is similar regardless of whether it is fully guided or half-guided.
