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.
