人们对牙齿的要求,已不再局限于某些疾病的防治,而更注重牙齿的整齐、协调与清洁。目前,一种比较理想的牙体修复材料——光固化复合树脂,已广泛用于牙体的修复治疗中,现介绍如下: 光固化复合树脂应用于牙体龋坏,主要是前牙的吻合龋;牙颈部楔状缺损,不易做良好固位形者;牙体外伤,切缘缺损小于1/2;固定桥体的腹面脱落;畸形牙,比如过小牙、牙间隙过大;变色牙如四环素牙、斑釉症、牙髓坏死等异常情况。同时牙周组织必须健康,若有牙外伤,牙根损伤不超过其1/3。另外,还适用于对银汞充填材料敏感反应者。光固化复合树脂的充填修复过程分四步进行:
People's demands on the teeth are no longer confined to the prevention and treatment of certain diseases, but rather pay more attention to the tidiness, coordination and cleanliness of the teeth. At present, a relatively ideal dental restoration material - light curing composite resin, has been widely used in the restoration of the teeth, are described below: Light curing composite resin used in dental caries, mainly anastomosis of the anterior teeth Caries; dental wedge-shaped defect, not easy to do a good shape retainer; dental trauma, cut edge defect less than 1/2; fixed bridge body ventral shedding; deformed teeth, such as too small teeth, excessive tooth space; discolored teeth Such as tetracycline teeth, spot glaze disease, dental pulp necrosis and other anomalies. At the same time periodontal tissue must be healthy, if tooth trauma, root damage does not exceed 1/3. It is also suitable for those who are sensitive to amalgam filling materials. Light curing composite resin filling repair process in four steps:
