我们在此报告一个病例，一位因上颌骨恶性黑色素瘤而接受上颌骨次全切除术的患者，在仅有两颗牙种植体的支持下，进行了上颌骨修复体的功能和美学重建。一位76岁的女性被转介到我们的设施与无痛变色的上牙龈。经过多次检查，临床诊断为上牙龈恶性黑色素瘤（cT3N1M0 IVA期，美国癌症联合委员会）。采用Le Fort I截骨术和功能性颈淋巴结清扫术进行上颌骨次全切除术。传统的切除义齿，并采用术后，但无法适当地保留，由于不足的剩余上颌骨结构。肿瘤切除后6个月，将两个假体植入双侧颧骨。磁性附着体作为种植体和切除义齿的附着体。应用这些种植体后，假体的固位和稳定性得到了显著改善。患者能够正常饮食。从美学角度来看，凹陷的上唇也得到了适当的修复，从而获得了可接受的面部外观。
We report herein a case of functional and aesthetic rehabilitation with maxillary prosthesis supported by only two zygomatic implants for a patient with severe maxillary defect resulting from subtotal maxillectomy for malignant melanoma of the upper gingiva. A 76-year-old woman was referred to our facility with non-painful discoloration of the upper gingiva. After several examinations, a clinical diagnosis of malignant melanoma of the upper gingiva (cT3N1M0 stage IVA, American Joint Committee on Cancer) was made. Subtotal maxillectomy utilizing Le Fort I osteotomy and functional neck dissection were performed. A conventional resection denture was made and employed postoperatively, but was unable to be suitably retained due to insufficient residual maxillary structures. Six months after tumor resection, two zygomatic implants were inserted into bilateral zygomatic bones. Magnetic attachments were applied as a mechanism for attaching the implants and resection denture. After application of these implants, retention and stability of the prosthesis was considerably improved. The patient became able to eat a normal diet. From an aesthetic perspective, the depressed upper lip was also properly restored, leading to an acceptable facial appearance.
