Loss of orbital content can cause functional impairment, disfigurement of the face, and psychological distress. Rehabilitation of an orbital defect is a complex task, and if reconstruction by plastic surgery is not possible or not desired by the patient, the defect can be rehabilitated by an orbital prosthesis. The prosthetic rehabilitation in such cases depends on the precisely retained, user-friendly removable maxillofacial prosthesis. Many times, making an impression of the orbital area with an accurate record of surface details can be a difficult procedure. The critical areas are making a facial moulage, mold preparation, and attaching the retention device, particularly when eyeglass frames are used. This case focuses on these hindrance factors. A simple basket was used for the impression tray to obtain the facial moulage. A putty mold was used, and attachment of the prosthesis to a retention device was accomplished with positional distance. This method proves to be an economical and simple way of making an orbital prosthesis.
眶内容物缺失可导致功能障碍、面部畸形和心理困扰。眼眶缺损的修复是一项复杂的任务,如果整形手术重建不可行或患者不希望进行,那么可以通过眼眶假体来修复缺损。在这种情况下,假体修复依赖于精确保留、易于使用的可摘式颌面假体。很多时候,获得准确记录表面细节的眶区印模是一个困难的过程。关键区域在于制作面部模型、模具准备和安装固位装置,尤其是在使用眼镜架时。本案例重点介绍了这些障碍因素。使用简单的篮状托盘获得面部模型。使用油灰模具,并通过位置距离将假体附着到固位装置上。该方法被证明是制作眼眶假体的一种经济、简单的方法。
