Large oro-facial defects result from cancer treatment consequences in serious functional as well as cosmetic deformities. Acceptable cosmetic results usually can be obtained with a facial prosthesis. However, retention of a large facial prosthesis can be challenging because of its size and weight. This article describes prosthetic rehabilitation of a 57-year-old man having a right lateral mid-facial defect with intraoral-extraoral combination prosthesis. A modified technique to fabricate a hollow substructure in heat-polymerizing polymethyl-methacrylate to support silicone facial prosthesis was illustrated. The resultant facial prosthesis was structurally durable and light in weight facilitating the retention with magnets satisfactorily. This technique is advantageous as there is no need to fabricate the whole prosthesis again in case of damage of the silicone layer because the outer silicone layer can be removed and re-packed on the substructure if the gypsum-mold is preserved.
大面积的口腔面部缺损是癌症治疗的后果，会导致严重的功能和美容畸形。通过面部义齿可以获得可接受的美容效果。然而，由于其体积大和重量大，大型面部义齿的保留具有挑战性。本文介绍了使用口腔内外联合义齿对 57 岁男性右侧中面部缺损进行修复的方法。展示了一种改良技术，即用热聚合聚甲基丙烯酸甲酯制作空心的底层结构来支撑硅树脂面部义齿。制作的面部义齿结构坚固耐用，重量轻，通过磁铁固定效果令人满意。这种技术的优点是，如果硅树脂层损坏，不需要重新制作整个义齿，因为只要保留石膏模型，就可以将外层硅树脂层去除并重新安装在底层结构上。
