In the literature, the technique of segmental osteotomy accompanied by interpositional grafting has been reported as a practical and predictable procedure with a low incidence of complications and a high probability of success [15,16,17,18,19]. This approach leaves the soft tissue on the oral side of the midcrestal incision attached to the crestal bone segment. Various studies have shown that alveolar osteotomy associated with interpositional grafting may be an effective alternative to other surgical techniques for increasing vertical bone height in the posterior maxilla and mandible [15,16,17,18,19]. The technique is based on interposing a bone graft between osteotomized bony segments, which act as a “sandwich,” offering good vasculature to both the segment and the graft and resulting in less bone resorption compared to the methods described before [15,16,17,18,19].

This case report describes clinical treatment using segmental osteotomy with interpositional bone grafting to rehabilitate the alveolar ridge in the posterior region of the maxilla with 9 years of follow-up.
