自1955年 Buonocore 研究了酸蚀釉质以增强树脂补牙材料与釉质的粘结力后,1968年 Roydhouse 首次将双酚 A-甲基丙烯酸缩水甘油酯(Bis-GMA)作为主体材料封闭点隙裂沟。1970年 Buonocore 尝试用光敏固化体系的 Bis-GMA 作防龋涂料,1973年用光敏固化充填材料修复折断牙的切缘。1979年2月开始,我们对48例楔状缺损患者的185枚患牙及43例釉质发育不全症患者的 Since 1955, Buonocore studied the acid etching enamel to enhance the adhesion of resin dental materials and enamel, Roydhouse for the first time in 1968 bisphenol A-glycidyl methacrylate (Bis-GMA) as the main material to seal the gap fissure . In 1970, Buonocore attempted to use Bis-GMA as a photo-curable system for caries-free coatings. In 1973, photo-curable fillers were used to repair the cut edges of broken teeth. Beginning in February 1979, we evaluated 48 patients with wedge-shaped defect in 185 patients and 43 patients with enamel hypoplasia
