口腔全瓷修复材料抛光方法研究进展

口腔全瓷材料是目前牙齿修复的主要材料,它具有稳定的色泽、良好的生物相容性以及出色的美观性。全瓷材料的分类目前主要有长石质瓷、玻璃陶瓷和多晶陶瓷。现如今,随着口腔技术不断发展与改进,促使众多研究学者对抛光工具对患者使用效果也引起了高度重视。牙科陶瓷抛光是一种单纯的机械性抛光,亦是一种磨削加工工艺中的精密磨削方式。抛光工具对瓷材料表面的磨削清除是通过磨粒直接完成的,结合剂具有固结磨粒、成形以及较强的支撑作用。抛光是指牙冠经过调磨后,利用工具将表面变成光滑表面的过程。全瓷冠在戴牙时通常需要调磨,该文就口腔全瓷修复体不同抛光工具表面处理方法及其研究进展等相关问题做一综述,希望能够对选择合适的抛光方法带来帮助。

Research Progress on Polishing Methods of Dental All-ceramic Restoration Materials

Oral all-ceramic material is the main material for dental restoration at present.It has stable color,good biocompatibility and excellent aesthetics.The classification of all-ceramic materials mainly includes feldspar porcelain,glass ceramics and polycrystalline ceramics.Nowadays,with the continuous development and improvement of oral technology,many researchers have caused great attention to the effect of fluoroscopy tools on patients.Dental ceramic polishing is a pure mechanical polishing,and it is also a precision grinding method in the grinding process.The grinding and removal of the surface of the porcelain material by the polishing tool is directly completed by the abrasive particles.The bonding agent has the function of consolidating the abrasive particles,forming and supporting.Polishing refers to the process of turning the surface of a dental crown into a smooth surface after conditioning.All-ceramic crowns usually need to be adjusted when wearing teeth.This article summarizes the related issues such as the surface treatment methods and research progress of different polishing tools for oral all-ceramic restorations,and hopes to bring meaning to the selection of a suitable polishing method.
