Since their introduction in 1992, light-hardened glass ionomer resin cements have shown great versatility for use in nonstressbearing restorations. On-command hardening, adhesive bonding, fluoride release, biocompatibility, and favorable thermal expansion and contraction properties are significant advantages to this class of materials. One such cement has shown excellent durability for more than 2 years, when used as a Class I restorative material for permanent posterior teeth. The objective of this article is to familiarize the reader with this relatively new cement and to describe a procedure for placement of intracoronal light-hardened glass ionomer resin restorations. Four cases are used to illustrate the clinical procedure.
自1992年问世以来,光固化玻璃离子树脂水门汀在非承受应力修复中展现出了极大的通用性。即时固化、粘结性、氟释放、生物相容性以及良好的热膨胀和收缩性能是这类材料的显著优点。当用作恒牙后牙的I类修复材料时,有一种这样的水门汀已显示出超过2年的优异耐久性。本文的目的是让读者熟悉这种相对较新的水门汀,并描述一种冠内光固化玻璃离子树脂修复体的放置方法。用四个病例来说明临床操作过程。
