三维打印口腔修复种植体的研究进展

Research progress of dental implant fabricated with 3D printing

三维打印是计算机辅助制造的一种,通过三维打印设备,将数字化设计转化为实体。随着各种数字化手段的发展,三维打印已广泛应用于口腔修复体的制作。口腔种植义齿被称作人类第二副牙齿,以其美观、舒适等优点成为临床修复热点。目前,口腔种植体主要采用传统方法制造,三维打印可以提高种植体的个性化程度和制作效率。众多研究已证实,三维打印种植体是可行的,但在种植体设计、表面修饰等方面尚未有统一结论。本文通过阐述三维打印金属及全瓷种植体的最新研究进展,旨在带来种植体材料选择、制作工艺、表面设计及修饰等方面的思考,为三维打印种植体的进一步研究提供参考,以期更好地服务于临床。

3D printing is a kind of computer aided manufacturing,which transforms digital model into green body through 3D printing equipment.With the development of various digital means,3D printing has been widely used in the manufacture of dental prostheses.Implant denture,known as the second set of human teeth,has become a hot spot in clinical practice for its advantages of aesthetic and comfort.At present,oral implants are mainly manufactured by traditional methods.3D printing can improve the implant personalization and production efficiency.Research shows that 3D printing implants are feasible,but there is no unified conclusion on implant design and surface modification.By introducing the latest research progress of 3D printed metal and all-porcelain implants,this paper aims to bring thoughts on implant material selection,production process,surface design and modification,and provide references for further research on 3D printed implants,so as to better serve the clinical practice.
