Extraoral maxillofacial rehabilitation for compromised or lost facial anatomy resulting from the surgical eradication of malignancy, trauma, or congenital anomalies is commonly accomplished with a silicone prosthesis. However, with increasing size and weight, a silicone prosthesis can lose retention. This report presents 2 patient treatments to introduce a fabrication and retention method for a lightweight acrylic resin facial prosthesis. The prosthesis was fabricated by bonding an acrylic resin facial shell to a computer-edited facial image printed with iron-on transfers. The completed prosthesis was attached to the skin with medical-grade double-sided adhesive tape, which maintained a tight marginal seal even when in contact with saliva and water. The strong prosthetic retention of the lightweight prosthesis enabled orofacial and speech rehabilitation, which makes it a promising alternative to the conventional silicone prosthesis, especially for the restoration of extensive maxillofacial defects.
口腔颌面外科学 对于因恶性肿瘤、创伤或先天畸形而导致的面部解剖结构受损或丧失，常采用硅橡胶假体进行修复。然而，随着假体体积和重量的增加，硅橡胶假体可能会失去固位力。本报告介绍了 2 例患者的治疗情况，旨在介绍一种用于制作轻质丙烯酸树脂面部假体的方法。该假体通过将丙烯酸树脂面部外壳与打印有热转印的面部图像进行粘合来制作。完成的假体通过医用级双面胶带固定在皮肤上，即使与唾液和水接触，也能保持紧密的边缘密封。这种轻质假体具有良好的固位力，可实现口颌和言语康复，是传统硅橡胶假体的一种有前途的替代方法，尤其适用于大面积颌面缺损的修复。
