Bone augmentation of the inferior floor of the maxillary sinus with autogenous bone or composite bone grafts: a histologic-histomorphometric preliminary report.
نویسندگان
چکیده
Thirteen patients were treated for elevation of the maxillary sinus floor with autogenous or composite (autogenous bone + hydroxyapatite granules) bone grafts and endosseous implants. Bone biopsies were taken both at graft positioning and at implant placement. Histologic and histomorphometric results suggest that graft architecture, conformation, and composition may influence the mean bone content at the end of the healing. Iliac bone grafts contained 53% bone, while chin bone grafts contained 66% bone. Composite bone grafts had the smallest percentage of bone: 44.3%. Chin block bone grafts had the largest percentage of bone content (69.3%), while chin particulate bone graft conformation had 62.6%. Although particulate grafts healed in only 4 months, bone quality and quantity allowed earlier implant placement.

BACKGROUND Prosthetic rehabilitation of the posterior maxilla with dental implants is often difficult because of proximity to the maxillary sinus and insufficient bone height. Maxillary sinus floor augmentation procedures aim to obtain enough bone with an association between biomaterials and autogenous bone. PURPOSE The purpose of this study was to evaluate histomorphometrically two grafting ...

The aim of the present clinical study was to determine, through histologic and histomorphometric investigations of human bone specimens, whether the addition of autogenous bone to the bone substitute material Bio-Oss can produce a high-quality implant site. To improve vertical bone height, 13 sinus floor elevations were carried out in a total of 12 patients. Augmentation of the maxillary sinus ...
متن کاملHistologic analysis of clinically retrieved titanium microimplants placed in conjunction with maxillary sinus floor augmentation.
In this study, a new approach involving placement and subsequent retrieval of titanium microimplants was employed for the histologic investigation of the implant-tissue interface in conjunction with maxillary sinus floor augmentation. Nine patients scheduled for sinus floor augmentation and simultaneous placement of Brånemark implants were included in the study. After a sinus graft procedure an...
متن کاملMaxillary sinus augmentation: histologic and histomorphometric analysis.
PURPOSE Implant placement in the posterior maxilla may often be contraindicated because of insufficient bone volume and the presence of the maxillary sinus. In these situations, sinus floor lifting and grafting frequently have been proposed as the best treatment. The aim of this study was to compare histologically the use of 100% autogenous bone versus a combination of autogenous bone and corti...
