Loss of tissue, whether congenital or traumatic or resulting from malignancy or radical surgery, is accompanied by esthetic and psychologic effects. This loss is more pronounced when the affected part is the eye and all orbital contents, resulting in gross mutilation. Success in maxillofacial prosthetics depends on the full cognizance of the principles that underlie facial harmony, color matching, anchorage and retention, weight bearing and leverage, durability and strength of materials used, tissue compatibility and tolerance. The restoration of orbital defects presents a challenge in maxillofacial prosthetics. Many variations exist in techniques and materials for fabricating orbital prostheses. Careful positioning of the ocular portion of the orbital prosthesis is one of the requirements for a successful esthetic result. A change of this position, which may occur during fabrication or may be due to distortion of the prosthetic housing or loss of retention of the prosthesis, may result in an unsatisfactory appearance. This article presents a simplified technique for fabricating an orbital prosthesis.
组织缺失，无论是先天性的、外伤性的、由恶性肿瘤导致的还是根治性手术造成的，都会伴随美学和心理影响。当受影响的部位是眼睛及所有眶内容物时，这种缺失会更加明显，导致严重毁容。颌面修复术的成功取决于对面部和谐、颜色匹配、固定与固位、负重与杠杆作用、所用材料的耐久性和强度、组织相容性和耐受性等基本原则的充分认识。眼眶缺损的修复是颌面修复术中的一项挑战。制造眼眶假体的技术和材料有很多种。眼眶假体眼部的精确放置是获得成功美学效果的要求之一。这个位置的改变，可能发生在制造过程中，也可能是由于假体外壳变形或假体固位丧失，可能会导致外观不理想。本文介绍一种制造眼眶假体的简化技术。
