Maxillary obturators are prostheses used to replace maxillary tissues, missing congenitally or removed by trauma or tumor ablative surgery. These prostheses are used to restore function (speech, swallowing, and mastication) and aesthetics. A considerable number of edentulous patients have difficulty in retaining this type of prosthesis. Utilization of osseointegrated dental implants is a significant adjunct in treating these cases, but it must be undertaken with careful planning to ensure predictable aesthetic results. The learning objective of this article is to discuss the technique of designing aesthetic maxillary prostheses supported by osseointegrated dental implants. The discussion includes indications and contraindications, and a postcarcinoma surgery case is used to illustrate the clinical procedure.
上颌阻塞器是用于替代上颌组织的假体，这些上颌组织或是先天性缺失，或是因外伤或肿瘤切除手术而被移除。这些假体用于恢复功能（言语、吞咽和咀嚼）以及美观。相当数量的无牙患者在佩戴这类假体时存在困难。使用骨结合牙种植体是治疗这些病例的一项重要辅助手段，但必须精心规划，以确保获得可预测的美学效果。本文的学习目标是讨论由骨结合牙种植体支持的美观上颌假体的设计技术。讨论内容包括适应证和禁忌证，并通过一个癌后手术病例来说明临床操作过程。
