Background : bone grafts represent one of the earliest devised to reconstruct bony defects in oral and maxillofacial surgery .
Aim of study :the present study was focused on developing better bone harvesting technique which is simple, safe with less post- operative morbidity.
Patients and methods : this study was conducted on 15 patients with facial bone defects , due to physiological resorption of alveolar ridge (60% of patients ), missile and road traffic accident (26% ).
Bone was harvested from intra-oral donor sites , he symphyseal region (66.6 % ) and retro-molar area (33.3 %). 53.3 % of patients were operated under local anesthesia and require no hospital admission, with little time consumption, while (46.6 %) patients were operated under general anesthesia. Both cortical and cancellous bone was harvested from intra- oral donor sites and fixed by mono- cortical screws.
Result : in this study , the complications of this technique for bone harvesting being minimal , donor site complications were occurred in three cases only (19.9 %) , which include hematoma formation and paraesthesia of the mental nerve , but there is no signs of teeth vitality loss in all patients , the degree of pain and swelling related to the donor sites being mild..
Conclusions: intra-oral bone graft harvesting simple, safe, less morbidity, little resorption , can be harvested under local anaesthesia with no or less time hospitalization period. Complication associated with this technique being minor, included paraesthesia, hematoma, teeth invitality.
