Rehabilitation of Severely Atrophic Maxilla with Le Fort I Advancement Surgery and Subperiosteal Implant in a Patient With Ectodermal Dysplasia

Abstract

Objectives: In this case, the patient with ectodermal dysplasia lost his teeth and acquired maxillary insufficiency. The aim of this case is to advance the maxilla using Le Fort I surgery and make fixation with a subperiosteal implant. Methods: On the three-dimensional model, a surgical guide for Le Fort I osteotomy and subperiosteal implant design was planned. In the surgery, Le Fort I osteotomy was made according to the guide, and maxillary advancement was obtained, then a subperiosteal implant was fixated. Prosthetic rehabilitation was made after 1 month. Results: Maxillary repositioning is obtained according to virtual planning and subperiosteal implant is used for both fixation and prosthetic rehabilitation. Proper fixation is ensured and full arch prosthetic rehabilitation supported by a subperiosteal implant is performed. Conclusion: With this technique, in the rehabilitation of atrophic maxilla, sagittal insufficiency is corrected with Le Fort 1 surgery, whereas the patient’s treatment period is shortened by placing a subperiosteal implant at the same time.
