Summary
Digital osteotomy templates show high accuracy in dental implant surgery, with minimal deviation between planned and actual bone cuts. This technique is accurate, quantifiable, and recommended for clinical use.
Area of Science:
- Dental Implantology
- Digital Dentistry
- Surgical Planning
Background:
- Immediate dental implant placement and restoration require precise surgical planning.
- Digital workflows, including cone beam CT (CBCT) and digital smile design (DSD), enable detailed pre-operative analysis.
- Intraoperative osteotomy accuracy is crucial for successful implant outcomes.
Purpose of the Study:
- To evaluate the immediate accuracy of a digital osteotomy template within a digital stackable template system.
- To assess the deviation between virtual osteotomy designs and actual surgical outcomes.
Main Methods:
- Four patients with dentition loss underwent immediate implant placement with intraoperative osteotomy.
- A digital stackable template, including an osteotomy guide, was designed using CBCT, DSD, and virtual wax-up.
- Postoperative CBCT was used to measure deviations in volume, linear displacement, and angular orientation compared to the ideal plan.
Main Results:
- Average volume deviation was 492.94 mm³ (21.21% of planned volume).
- Average linear deviation between actual and ideal osteotomy was 0.0248 mm.
- Average angular deviation of the bone plane was 6.03°.
Conclusions:
- The digital osteotomy template in the digital stackable template system demonstrates high consistency between virtual design and actual osteotomy.
- This clinical technique is accurate, quantifiable, and suitable for widespread adoption in dental implant surgery.
