The autologous bone graft, on the contrary, applied with outstanding success in oral and maxil- lofacial surgery for decades, has no lobby. Is the ap- plication of autologous bone grafts, which needs to be harvested beforehand in a second surgery, out- dated under these circumstances? Toanchordentalimplantsinthejawbonesuccess- fully, sufficient vertical and transversal bone sub- stancemustbeavailable.1 Ifthereisnotenoughbone substance,eitheryouhavetoabstainfrominserting implants or you have to create the necessary re- quirements. The quality value of materials for elimi- nating the bone deficit is defined by their biological potency and biomechanical properties.2 The autologous bone graft is the only material so far that complies with the condition necessary for successful bone augmentation according to Garg et al., namely osteogenesis, osteoinduction, and osteo­conduction in equal measure.3 Besides intra-­ oral donor areas like the chin, the retromolar region, zygomatic buttress, and calvaria, mainly the tibial head as well as the anterior and posterior iliac crest bones are suited in particular for larger bone defi- cits.4-8 We do not, however, want to discuss the ­numerous bone replacement materials, BMP, stem cell fractions, or PRP, available on the market in this study.9, 10 Patient population and method The purpose of this prospective longitudinal study is to examine the morbidity after harvesting and transplanting autologous pelvic bone to eliminate jawbone deficits. 69 adult patients (37 f/32 m) aged between 31 and 73 years (average age at the time of the inter- vention 57.8 years, median age 52.5 years) who had undergone harvesting of autologous bone Fig. 1a: Bone deficit region 15–18, alveolar bone thin as an eggshell.
