Le Fort I Osteotomy with Iliac Bone Grafts and Delayed Oral Implants for the Rehabilitation of Extremely Atrophied Maxilla

Abstract

Abstract In this case report, the rehabilitation of a severely resorbed edentulous maxilla with Le Fort I osteotomy combined with interpositional autogenous bone grafts was presented. A 46-year-old woman applied to our clinic for the rehabilitation of edentulous maxilla and mandible. Her systemic history revealed diabetes type 1. It was seen that the maxilla was severe atrophic and interocclusal distance was increased due to excessive bone loss both vertically and horizontally. The patient was planned to undergo iliac bone graft with Le Fort 1 osteotomy. The maxilla was positioned 6 mm forward and 3 mm down. First, interposition grafting was performed in combination with Le Fort I surgery. Implants were placed after 4 months. Le Fort I osteotomy combined with inter-positional autogenous bone grafts gives successful results in the edentulous patient who has excessive resorption pattern with Class-III occlusal relationships and increased inter-occlusal distance.
