[Intraoral autogenous onlay block bone grafting for implant dentistry].
The use of autogenous bone graft with endosseous implant for the reconstruction of alveolar ridge deficiencies has been reported with increasing frequency in the past two decades. These bone grafts were harvested mainly from extra oral sites. Various donor sites have been described in the literature including the calvarium, tibia and iliac crest, the latter being most common. Due to the need for hospitalization, general anesthesia and the great morbidity of surgery associated with these donor sites, alternative intra oral sources for graft harvest have been suggested. The most common sites for, being the mandibular symphysis and the mandibular ramus. For the repair of localized alveolar bone defects these donor sites are advantageous. In addition to the ease of donor site access and minimal morbidity, membranous bone grafts show less resorption, good incorporation and shorter healing times. The use of these bone grafts allow us to correct the alveolar ridge height, width and trajectory prior to implant placement thus not only enable a better surgical success, but also should enhance a better prosthetic results as well.
