The prosthetic rehabilitation of maxillofacial defects is especially challenging when the patient is edentulous. Although dental implants are used to enhance the retention and stability of both facial and maxillary prostheses, combining facial and maxillary prostheses is extremely difficult. This article describes the prosthetic treatment of an edentulous patient with a large maxillary and facial defect. After placing dental implants in the remaining maxilla, a maxillary obturator prosthesis supported by a milled bar attachment was fabricated. The facial prosthesis was retained by a magnetic attachment to the maxillary obturator prosthesis. As the obturator prosthesis was supported securely by this sturdy attachment, the facial prosthesis was stable during mastication and facial movement. The patient reported improvement in prosthesis retention and stability. Both the masticatory and the speech functions of the patient improved.
当患者无牙时，颌面缺损的修复重建尤其具有挑战性。尽管牙种植体用于增强面部和上颌修复体的固位和稳定性，但将面部和上颌修复体相结合极为困难。本文描述了一位上颌和面部存在大面积缺损的无牙患者的修复治疗。在剩余上颌骨植入牙种植体后，制作了一个由铣削杆附着体支持的上颌阻塞器修复体。面部修复体通过磁性附着于上颌阻塞器修复体。由于阻塞器修复体通过这种坚固的附着体得到稳固支撑，面部修复体在咀嚼和面部运动时保持稳定。患者报告修复体的固位和稳定性有所改善。患者的咀嚼和言语功能均得到改善。
