The use of methods to promote tissue regeneration has been widely used in implantology in clinical situations where there are bone deficiencies and anatomical limitations to install implants. The evolution of biomaterials has facilitating clinical resolution for the installation of implants with a safe and reliable prognosis. The advantage is to promote greater comfort, function and aesthetics, in addition to preserving the surrounding soft tissues. This clinical report illustrates an implant supported rehabilitation using bovine grafting to promote guided bone regeneration (GBR) in the same chair time and resulting in osseointegration of the implants. The patient received cone-morse dental implants in the anterior maxilla, and bovine biomaterial (Bio-Oss®) protected by a resorbable collagen membrane. After installing the implants, immediate provisionals were made and after the osseointegration period, second-stage surgery was performed and new provisionals were made. The definitive prosthesis was finalized involving other adjacent elements as previous clinical planning. We conclude that the GBR technique contributed to the successful treatment and osseointegration of the titanium implants besides improvement of soft contour of anterior region. The patient was satisfied in terms of aesthetics and function.
