A case is reported assessing the problems encountered after surgical resection of the maxilla. The use of a hollow box obturator and details of its construction are described. The importance of skin grafting of the maxillary defect and use of available anatomical undercuts to optimise support and retention of the obturator is stressed. By provision of a lightweight hollow obturator, the weight of the prosthesis is kept to a minimum, helping retention, and allowing good resonance during speech. Initially the patient was to be assessed for an implant retained prosthesis, however, a satisfactory conventional prosthesis met the functional and aesthetic needs of the patient and avoided the need for further surgery for placement of implants.
报告了一例评估上颌骨手术切除后所遇问题的病例。描述了中空盒式闭孔器的使用及其制作细节。强调了对上颌骨缺损进行植皮以及利用现有的解剖倒凹来优化闭孔器的支撑和固位的重要性。通过提供轻质的中空闭孔器，将假体重量保持在最低限度，有助于固位，并在说话时实现良好的共鸣。最初计划对患者进行种植体固位假体的评估，然而，一个令人满意的传统假体满足了患者的功能和美学需求，避免了为植入种植体而进行进一步手术的必要性。
