肿瘤,先天性疾病,真菌感染,外伤是眼眶缺损的主要原因。各种保持机制,如粘合剂的应用,利用机械底切,和植入物支持的附件通常用于颌面部假体。在轨道区域,与其他机制相比,磁铁保留附件的结果是有利的。保持磁体的假体的不同优点是在插入或移除期间需要较少的手动灵活性和更好的卫生维护。颌面部区域的皮肤-植入物界面和厚组织是至关重要的要点,在植入物的规划和放置过程中应给予重视。理想情况下,眼眶假体的植入部位是外侧,红外-,和轨道区域的眶上边缘。以下病例系列描述了两种不同的方法,可通过单独设计的带有磁性附件和机械底切保留的眼眶假体的植入物来修复由于毛霉菌病而导致的眼球排出的患者。
Neoplasms, congenital disorders, fungal infections, and traumatic injuries are the predominant causes of orbital defects. Various retentive mechanisms such as application of adhesive, utilization of mechanical undercuts, and implant-supported attachments are generally used in the maxillofacial prosthesis. In the orbital region, the result of magnet-retained attachments is favorable compared with other mechanisms. Different advantages of the magnet-retained prosthesis are less manual dexterity needed during insertion or removal and better maintenance of hygiene. The skin-implant interface and thick tissues in the maxillofacial region are the critically important points that should be given importance during the planning and placement of implants. Ideally, implant sites for orbital prosthesis are the lateral, infra-, and supraorbital rims of the orbital region. The following
case series describes two different methods to rehabilitate patients with an exenterated eye due to mucormycosis by individually designed implant with magnetic attachment and mechanical undercut-retained orbital prosthesis.
