Abstract

With the loss of dental elements, natural bone dimensional changes occur, which often make it impossible to install dental implants without the need for grafting procedures prior to implant surgery for the esthetic-functional rehabilitation of our patients. Correcting vertical bone defects to re-establish the correct relationship of the alveolar crest in the posterior mandible is a major challenge for implant dentists. In the literature, segmental osteotomy associated with interpositional bone grafting has been shown to be a viable alternative for bone rehabilitation in vertical bone defects in the posterior mandible, provided that the correct indications are followed, with the appropriate surgical techniques. In this specific case, the interpositional grafting technique represented a safe and predictable procedure for vertical bone augmentation with segmental osteotomy associated with interpositional grafting. Segmental osteotomies associated with interpositional grafts are considered a predictable technique, provided they are well indicated and respect biological and technical limits for the rehabilitation of atrophic mandibular posterior regions. Success rates in the literature are very high, as is the survival of dental implants placed in the augmented areas.
