Application of autogenous block bone graft in the reconstruction of severe alveolar crest defect
Patients with severe alveolar ridge defects cannot be directly implanted and repaired,which seriously affects their quality of life.Onlay bone grafting is the main solution for severe alveolar ridge bone defect reconstruction,among which autogenous block bone grafting is the most widely used and is also the focus of clinical research on bone tissue reconstruction.This article expounds the characteristics and basic principles of autogenous bone block grafting,and comprehensively analyzes the selection of autogenous bone donor site,the principles of surgical operation,and the progress of bone graft techniques.In order to help surgeons make correct clinical decisions,increase the predictability of surgical effects,and improve the level of clinical diagnosis and treatment.
