数字化上颌骨缺损赝复体修复新进展

New Progress in Digital Prosthesis for Maxillary Defect

上颌骨缺损是口腔颌面部缺损最常见的类型,但传统取模制作赝复体的方式操作复杂、修复效果欠佳。数字化技术为上颌骨缺损的赝复体修复提供了新的途径。不同学者的研究提出不同的数字化实现方式,都大大改善了赝复体的制作过程和临床效果,成为上颌骨缺损赝复体修复的重要发展方向之一。本文利用万方数据平台及PubMed数据库进行检索,从上颌骨缺损的数字模型获取方式、赝复体三维设计、赝复体数字化加工、数字化种植辅助修复上颌骨缺损等方面对数字化上颌骨缺损赝复体修复技术进行分析,其中包括各种新技术和新设计理念的联合应用,以及新材料制作赝复体的临床尝试。以多学科融合方式,以外形和功能重建的综合性修复为理念,为上颌骨缺损数字化修复指明新的发展方向。

Maxillary defect is the most common type of oral and maxillofacial defect,while the traditional method to make prostheses by molding and hand processing is complicated and the effect is unsatisfying.Digital technology serves a new way of rehabilitation of maxillary defects.The research of different scholars has proposed different digital implementation methods,which have greatly improved the production process and clinical effect of the prostheses.Digital technology has become one of the most important development directions for rehabilitation of maxillary defects.In this study,we used Wanfang Data Platform and PubMed database to retrieve articles on digital prosthesis for maxillary defects,including digital model acquisition,three-dimensional design of the prostheses,digital fabrication of the prostheses and digital implant-assisted rehabilitation for maxillary defects.The contents included the joint application of various new technologies and new design concepts,as well as the clinical attempt to make prostheses using new materials.With a multidisciplinary approach,the comprehensive concept of shape and function reconstruction promises a new development direction for digital rehabilitation of maxillary defects.
