This study introduces a digital workflow for precise bone augmentation in oral implantology, achieving 95.82% accuracy. This method offers a controllable and effective alternative to traditional techniques.
Area of Science:
- Oral Implantology
- Digital Dentistry
- Guided Bone Regeneration
Background:
- Traditional bone augmentation relies heavily on operator experience.
- A digital solution is needed for precise bone augmentation in oral implantology.
Observation:
- A novel digital workflow was developed for precise alveolar bone augmentation.
- This involved intraoral scanning, DICOM data, and digital implant design.
- 3D-printed models were used to preform titanium mesh for guided bone regeneration.
Findings:
- The digital workflow achieved an average vertical bone gain of 2.48mm and horizontal bone gain of 4.11mm.
- The accuracy of the final actual augmentation reached 95.82%.
- Key bone dimensions, including labial bone thickness, met or exceeded targets.
Implications:
- This virtually digital guided bone regeneration workflow demonstrates precision and controllability.
- Further randomized controlled trials are needed to compare its safety and effectiveness against other bone augmentation procedures.
