REPAIR OF ORBITAL DEFECTS WITH IMPLANT-RETAINED PROSTHESES

目的探讨种植体支持的赝复体修复眼眶部缺损的修复技术及临床效果.方法因肿瘤切除术后致眼眶部缺损患者2例,男1例,48岁;女1例,23岁.在患者眼眶区分别植入4个种植体,半年后行二期手术,暴露种植体安放愈合基台,二期术后7周开始取印模进行赝复体制作,2～3周完成.赝复体使用专用硅橡胶材料制作,均采用磁性固位方式. 结果修复术后分别随访2年和8年.种植体骨结合牢固,未出现种植体周围炎性反应.修复制作过程顺利,固位可靠,患者对外观、颜色均满意. 结论种植体支持的赝复体可以应用于眼眶部缺损的修复,手术创伤小,患者佩戴方便,固位可靠,外观效果满意.To evaluate the clinical result of using osseointegrated implants to repair removable orbital prostheses in repairing orbital defects.Two patients with orbital defects caused by orbital tumor were treated. Each of them got 4 implants. After average 6 months, we performed the secondary operation. After 7 weeks, we took impressions to make the implant-retained prostheses. The magnetic attachment was adopted. The prostheses were made of polysiloxane material (Factor II, Lakeside, Ariz).Both of the patients got the successful facial prostheses and were followed up 2 and 8 years respectively. All the implants were integrated well. There were no apparent inflammatory reactions in the soft tissue around percutaneous implants. The patients were satisfied with the facial appearance.Implant-retained orbital prostheses are safe and effective in repairing orbital defects.首都医学发展科研项目PubMed中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)04300-3031
