In maxillary bone, several pathologies or lesions may cause maxillary alveolar atrophic (MAA), that is, a bone reabsorption frequently provoked by tooth loses or extractions. Tooth loses or extractions are one of the most common clinical situations observed in patients. The MAA could become a signifi cant functional and aesthetic risk for the use of tooth implants or any other prosthetic rehabilitation. Several biomaterials have been used as bone graft; they must fulfi l requirements like biocompatibility and a suitable function. A synthetic dense ceramic granulate of β-TCP, BIOGRAFT-G® (BIOMAT), in form of irregular shape granules with a grain size between 0.1 mm and 0.4 mm, was used in this study as graft material. The clinical studies include 178 patients, treated in Pre-implantology and Trans-implantology bone remodelling, prevention of residual ridge reabsorption by socket grafting and Periapical Surgical. In the fi nal evaluation of effectiveness after 6 month of surgery most of cases were qualifi ed as Success (98.3%), observing in the treated site a remodeled bone similar to the one in the adjacent tissue and almost no trace of implanted biomaterial. However, 3 cases were qualifi ed as Failure, all of them in patients that underwent the fi lling of dental sockets treatment, caused by the exfoliation of granules or a septic process. According to the obtained results, Biograft-G® proved to be a biodegradable, biocompatible, effectiveness and safety bone graft biomaterial in the studied treatments.
