Complicanze dei siti donatori di prelievo osseo intraorali ed extraorali

INTRODUCTION: Dental rehabilitation of partially or totally edentulous patients with oral implants has become a common practice in the last decades with reliable long-term results. However, unfavourable conditions of the alveolar ridge, due to atrophy, periodontal disease and previous trauma, may lead to an insufficient bone volume or unfavorable vertical, transverse, and sagittal interarch relationship, which may render implant placement impossible or unacceptable from a functional and esthetic viewpoint. The use of intraoral or extraoral bone grafts seems to be a predictable technique for the correction of facial jaws atrophy. RETROSPECTIVE STUDY. After reviewing the most recent literature, the Authors present a review of morbidity associated with bone harvesting in more than 1000 patients. RESULTS AND CONCLUSIONS. Data reported seem to show that bone augmentation of atrophic edentulous ridges with bone grafts is an acceptable procedure that may allow to maintain the initial bone gain without important complications linked to the donor site.
