Le Fort I and posterior maxillary segmental osteotomy for prosthodontic rehabilitation: A case report and review of the literature

to describe a surgical treatment of a case in vertical posterior maxillary alveolar ridge excess and to perform a literature review of various surgical options. we described a patient treated with a Le Fort I and a posterior maxillary segmental osteotomy (PMSO) for prosthodontic rehabilitation. A literature review on surgical treatments in posterior maxillary alveolar ridge excess is performed on Scopus, Embase, Pubmed and Cochrane with specific keywords. the case described is finally rehabilitated with implants in the mandible according to a correct Spee curve and occlusal plane. 49 articles describe surgical procedures of vertical posterior maxillary alveolar ridge excess. Only two reviews are described. literature has paid little attention to different combined orthognathic surgery procedures in prosthodontic rehabilitation of posterior maxilla. The orthognathic option is sometimes considered aggressive and difficult but with proper knowledge of the technique and surgical experience, correct and stable modification of inter arch space can be reached with predictability. correct surgical and dental prosthetic planning are important to achieve a stable functional and aesthetic solution for patients. • Prosthodonticrehabilitation in patients with severe extrusion of posterior maxilla is complex. • Le Fort I osteotomy and posterior maxillary segmentation stabilize extruded posterior maxilla. • Precise planning and technique prevent surgical complications. • Positive long-term results, with stable occlusion and bones contact avoid relapse. • A multidisciplinary approach is necessary for effective prosthetic rehabilitation.
