Abstract
BackgroundFunctional rehabilitation of patients afflicted with severe mandibular and maxillary alveolar atrophy might be challenging especially in malformed patients.MethodsTreatment planning using sinus lifting and implant placement before Le Fort I maxillary osteotomy in a patient with severe mandibular and posterior maxillary alveolar atrophy and skelettal class-III conditions due to cleft palate are described.ResultsA full functional and esthetic rehabilitation of the patient was achieved by a stepwise surgical approach performed through sinus lifting as the primary approach followed by implant placement and subsequent Le Fort I maxillary osteotomy to correct the maxillo-mandibular relation.ConclusionStabilisation of the maxillary complex by a sinus lifting procedure in combination with computer aided implant placement as preorthodontic planning procedure before Le Fort I maxillary osteotomy seems to be suitable in order to allow ideal oral rehabilitation especially in malformed patients.
Highlights
Functional rehabilitation of patients afflicted with severe mandibular and maxillary alveolar atrophy might be challenging especially in malformed patients
The main basic criteria for restauration of the edentulous maxilla and mandible are adequate bone mass and ortholalveolar form [6]. This can be achieved by augmentation of the available substrate using established techniques such as vertical and lateral augmentation of the alveolar ridge, sinus floor bone grafting and orthognathic surgery [5,7,8,9]
Edentulous patients with a skelettal class III jaw relationship have a poor chance of successful oral rehabilitation if they are provided exclusively with implant-supported prostheses unless supplementary surgery is provided [5,12,13]
Summary
A full functional and esthetic rehabilitation of the patient was achieved by a stepwise surgical approach performed through sinus lifting as the primary approach followed by implant placement and subsequent Le Fort I maxillary osteotomy to correct the maxillo-mandibular relation
