Abstract：
Defects can form after tumors in the maxillary region are resected surgically. Maxillofacial defects can affect a patient\'s physical, psychological, and social status. Surgery reduces the residual teeth and tissue\'s ability to provide optimal cross-arch support, stability, and retention. The design of the obturator can improve the esthetics of the prosthesis and give it a more lifelike appearance. This case report describes the fabrication of a cast metal framework design for a partial obturator prosthesis in a maxillectomy patient.
摘要：
手术切除上颌区域的肿瘤后可能会形成缺损。颌面部缺陷会影响病人的身体,心理,和社会地位。手术减少了残余的牙齿和组织的能力，以提供最佳的交叉弓支持，稳定性,和保留。闭孔的设计可以提高假体的美观性，使其外观更加逼真。此病例报告描述了上颌骨切除术患者的部分闭孔假体的铸造金属框架设计的制造。
