Posterior segmental collapse causes narrowing of interarch space and prevents adequate restoration in the posterior quadrant. Posterior maxillary segmental osteotomy (PMSO) is an alternative option that enables prosthodontic restoration with an implant-supported fixed partial denture. The following clinical report describes prosthodontic rehabilitation with fixed prostheses after a posterior maxillary segmental osteotomy for a patient with a partially edentulous mandible.
后段塌陷会导致牙弓间隙变窄，并妨碍后牙象限的充分修复。上颌后段截骨术（PMSO）是一种替代选择，可通过种植体支持的固定局部义齿实现修复治疗。以下临床报告描述了一位下颌部分牙列缺失患者在上颌后段截骨术后使用固定修复体进行修复治疗的情况。
