Co-1粘固剂即牙用羧聚复合陶瓷是近年来由昆明齿科材料厂研制的一种新型牙用充填材料。据文献报道 Co-1粘固剂的陶瓷粒度比一般复合树脂所用填料为小,粉液反应完全,生物相容性好,对牙髓无刺激,而且其中含 CaF_2晶体具有防龋作用。我院自1987年6月以来,用 Co-1粘固剂修复100例297颗牙体缺损,现介绍如下。临床资料本组100例中男63例,女37例,年龄最小4岁,年龄最大66岁。297个牙中楔状缺152个,各类龋洞105个,残冠18个,牙釉质发育不全牙面22个。本组患者均用 Co-1粘固剂修复牙体缺损,经3～6月后,充填各类楔状缺损152个牙中脱落14 Co-1 cement that dental carborundum composite ceramic dental materials factory in Kunming in recent years developed a new type of dental filling material. It has been reported in the literature that the ceramic particle size of Co-1 cement is smaller than that used for general composite resins, the reaction of powder liquid is complete, the biocompatibility is good, and the dental pulp is not irritating. Moreover, the crystal containing CaF 2 has anticaries effect. Our hospital since June 1987, with Co-1 cement repair 100 cases of 297 tooth defects, are described below. Clinical data The group of 100 patients, 63 males and 37 females, the youngest 4 years old, the oldest 66 years old. There were 152 wedges in 297 teeth, 105 cavities in all kinds, 18 canines and 22 teeth with enamel hypoplasia. The group of patients with Co-1 cement to repair dental defects, after 3 to 6 months, filled with various types of wedge-shaped defects in 152 teeth off 14
