OBJECTIVES: The aim of this study was to radiographically assess the vertical and horizontal alterations of buccal alveolar bone after the insertion of a post-extractive implant using Bio-Oss(®) Collagen graft. MATERIAL AND METHODS: The study was designed as a prospective study. Adult patients were eligible for the study if they needed one or more immediately inserted and immediately restored implant replacing teeth to be extracted within region 15-25. After the insertion, the buccal gap was carefully grafted using Bio-Oss(®) Collagen and the implant immediately restored. Cone-Beam Computed Tomography (CBCT) was performed immediately after surgery and a series of measurements were made to determine the dimension of the buccal bone plate and the void between implant and extraction socket. A second CBCT was taken and the measurements repeated after 12 months. RESULTS: Altogether, 69 patients were included in the study; a total of 69 implants were inserted. The study demonstrated that the extraction of a tooth and the immediate insertion of an implant together with an xenograft resulted in alterations of the vertical and horizontal dimension of the buccal bone plate (respectively, 25.6% and 29.3%). Nevertheless, the vertical and horizontal gap reduction was nearly complete (respectively, 99.3% and 99.1%) and the implant was normally in contact with buccal bone. CONCLUSIONS: Implant placement into extraction sockets can result in favorable radiological results even in the presence of evident alterations of the buccal bone wall.
