Onlay bone grafting is a safe, predictable procedure for restoring jawbone volume with success rates between 90% and 95%. When performed by maxillofacial surgeons using rigid fixation, it effectively prepares the jaw for implants. Primary risks include graft resorption, infection, or minor nerve sensitivity.
- Success rate: Clinical success typically ranges from 85% to 95% under skilled surgical care.
- Graft resorption: Natural bone shrinkage of 20% to 30% can occur during the healing phase.
- Nerve safety: Rare temporary numbness can occur if grafting happens near lower jaw nerves.
- Fixation protocol: Rigid fixation using titanium screws improves success rates from 70% to 90%.
Bookimed Expert Insight: Data from top Turkish clinics like Medipol University Ankara shows a focus on academic-led surgery. Prof. Dr. Hakan Alpay Karasu and other specialists often combine onlay grafts with advanced 3D imaging. This academic oversight ensures precise graft volume calculation, which is critical since up to 40% of the graft can be lost if not properly immobilized during the first 6 months.
Patient Consensus: Patients emphasize that while the 3–6 month healing timeline is long, the structural stability gained is superior to faster alternatives. Many recommend verifying that the surgeon has performed over 100 onlay cases to ensure the best vascularization and long-term graft retention.
