从高分子科学进入牙科材料学后,近年来,在牙齿硬组织的粘结研究方面,取得了较大的进展。R、L、Bowen 合成 Bis—GMA 树脂奠定了牙体粘结的基础。从1965年 Bowen发表了一系列研究偶联剂 NPG—GMA(氮一苯基甘氨酸—甲基丙烯酸缩水甘油醚)的报告。他发现以往的各种树脂,与牙体表面粘结后,只要保持干燥可以基本显示最初的 After entering the field of dental materials science from polymer science, great progress has been made in the research on the bonding of dental hard tissues in recent years. R, L, Bowen Synthesis of Bis-GMA resin lays the foundation for tooth bonding. From 1965 Bowen published a series of reports on the coupling agent NPG-GMA (N-phenylglycine-glycidyl methacrylate). He found that the past, a variety of resin, and the surface of the tooth surface, as long as the remains dry can basically show the original
