Computer-aided intraoral block bone grafting significantly improves accuracy and efficiency for horizontal ridge augmentation compared to conventional methods. This digital workflow enhances precision in bone block placement and reduces surgical time.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Regenerative Dentistry
Background:
- Horizontal alveolar ridge defects present challenges for dental implant restoration.
- Conventional intraoral block bone grafting techniques can be technique-sensitive and time-consuming.
Purpose of the Study:
- To compare the accuracy and efficiency of computer-aided intraoral block bone grafting with conventional methods.
- To evaluate the outcomes of computer-aided versus conventional techniques for horizontal ridge augmentation.
Main Methods:
- 28 patients with horizontal alveolar bone defects underwent intraoral block bone grafting.
- Patients were randomized into a computer-guided surgery group and a conventional control group.
- Primary outcomes included root mean square estimate (RMSE) of bone block fit; secondary outcomes included trimming time and complications.
Main Results:
- The computer-guided group showed significantly lower RMSE values for both outer (0.37 ± 0.16 mm) and inner (0.35 ± 0.15 mm) bone block contours compared to the control group (0.72 ± 0.29 mm and 0.48 ± 0.17 mm, respectively).
- Bone block trimming time was significantly shorter in the guided group (401.51 ± 97.60 s) versus the control group (602.36 ± 160.57 s).
- The control group experienced more complications, including secondary grafting and temporary neurosensory disturbances.
Conclusions:
- A fully digital workflow using computer-aided intraoral block bone grafting offers superior accuracy and effectiveness for horizontal ridge augmentation.
- This advanced technique streamlines the surgical process and potentially reduces patient morbidity.
