摘　　要：Purpose:This study evaluated the methods and clinical effects of multidisciplinary collaborative treatment for occlusal reconstruction in patients with old jaw fractures and dentition defects.Methods:Patients with old jaw fractures and dentition defects who underwent occlusal reconstruction at the Third Affiliated Hospital of Air Force Military Medical University from January 2018 to December 2022 were enrolled.Clinical treatment was classified into 3 phases.In phase I,techniques such as orthognathic surgery,microsurgery,and distraction osteogenesis were employed to reconstruct the correct 3-dimensional(3D)jaw position relationship.In phase II,bone augmentation and soft tissue management techniques were utilized to address insufficient alveolar bone mass and poor gingival soft tissue conditions.In phase III,implant-supported overdentures or fixed dentures were used for occlusal reconstruction.A summary of treatment methods,clinical efficacy evaluation,comparative analysis of imageological examinations,and satisfaction questionnaire survey were utilized to evaluate the therapeutic efficacy in patients with traumatic old jaw fractures and dentition defects.All data are summarized using the arithmetic mean±standard deviation and compared using independent samplet-tests.Results:In 15 patients with old jaw fractures and dentition defects(an average age of 32 years,ranging from 18 to 53 years),there were 7 cases of malocclusion of single maxillary fracture,6 of malocclusion of single mandible fracture,and 2 of malocclusion of both maxillary and mandible fractures.There were 5 patients with single maxillary dentition defects,2 with single mandibular dentition defects,and 8 with both maxillary and mandibular dentition defects.To reconstruct the correct 3D jaw positional relationship,5 patients underwent Le Fort I osteotomy of the maxilla,3 underwent bilateral sagittal split ramus osteotomy of the mandible,4 underwent open reduction and internal fixation for old jaw fractures,3 underwent temporomandibular joint surgery,a
