A retrospective evaluation of bone graft success, implant survival rate and marginal bone loss

Abstract

Bone grafting serves to restore the alveolar bone defect, providing adequate alveolar bone essential for long-term implant survival. Therefore, it is of interest to evaluate bone graft success, implant survival rate and marginal bone loss. Hence, data from 85 patients showed 112 implants performed in grafted sites achieved a 95.5% survival rate and the bone grafting success reached 92.8%. Auto-genous grafts displayed higher functionality than allografts and xenografts did. At 12 months the mean marginal bone loss measured 1.12 ą 0.28 mm according to graft classification and implant placement site (p<0.05). Bone grafting shows its effectiveness for improving implant stability and achieving enduring success within patients who need large bone grafts.
