This clinical report describes the design and fabrication of an implant-retained and soft-tissue-supported obturator prosthesis and a magnetic retained midfacial prosthesis for a patient with a midfacial defect following bilateral total maxillectomy, removal of the left zygoma, and excision of the entire upper lip. The patient underwent multiple head and neck surgeries for 4 separate primary oral cancers, 1 recurrence, and 1 pulmonary metastasis. The definitive obturator prosthesis was retained by 1 zygomatic implant with soft-tissue support and retention. The midfacial prosthesis was attached to the obturator prosthesis with magnets, improving appearance and the recovery of significant aspects of the patient's speech and swallowing. Some improvement in mastication was observed.
本临床报告描述了为一位双侧全上颌骨切除术、左侧颧骨切除和整个上唇切除后患有面中部缺陷的患者设计和制作种植体固位和软组织支撑的闭塞器义齿以及磁性固位的面中部赝复体。该患者因 4 处原发性口腔癌、1 次复发和 1 次肺转移接受了多次头颈部手术。最终的闭塞器义齿由 1 个带有软组织支撑和固位的颧骨种植体固位。面中部赝复体通过磁铁附着在闭塞器义齿上,改善了患者的外观和显著的言语和吞咽功能的恢复。咀嚼功能也有所改善。
