摘要
随着口腔技术的发展及全瓷种植体的广泛应用,对于牙种植体表面处理技术的要求越来越高,牙种植体表面粗化的处理方法是指采用机械或者化学方法在植体表面形成符合形态的微结构或者同位结构,扩大其黏结面积,使其表面活化,增强其表面的自由能,并增强了瓷和树脂黏结性。目前国内外常用的表面处理的方法有机械法和化学法,主要技术包括机械打磨、肽浆喷覆(TPS)、酸蚀(etching)、喷砂(sand blasting)、改良喷砂、激光蚀刻、硅涂层和联合使用等,随着技术的发展,开发出多种植体。
With the development of stomatology technology and the wide application of full-ceramic implant,there are higher requirements on the surface treatment technology of dental implant.The treatment method for the surface roughening of the dental implant refers to the adoption of the mechanical or chemical means to construct the micro-structure or appositive structure with the appropriate forms on the surface of the implant to expand the bonding area,activate the surface,enhance its free energy and thus intensify the bonding of the ceramic and resin.Presently,the common surface treatment methods include the mechanical and chemical ones both at home and abroad,such as the technical grinding,Ti plasma spraying(TPS),etching,sand blasting,refined blasting,laser etching,silicon coating and combined adoption.There have been various implants as the technology develops.
