可见光复合树脂是新型的光固化复合树脂,有其独特的一些优点。近年来发展很快,渐渐受到口腔医学界重视,已广泛应用于临床。一、可见光复合树脂及其固化器的特性可见光复合树脂是由多官能度的树脂及混合型或超微型的无机填料组成,此外,还有光敏剂、还原剂、阻聚剂、看色剂等。可见光固化器是由钨卤素灯、光导管、开关、定时器、散热装置等组成。有的安装有滤光片。波声长一般在450～550nm范围,有效波长470～510nm。光传导有液态或玻璃纤维的光导管、石英棒等。电压的变化对光强
Visible light composite resin is a new light-cured composite resin, has its own unique advantages. In recent years, the rapid development, gradually by the dental profession, has been widely used in clinical. First, the characteristics of visible light composite resin and curing device Visible light composite resin is a multi-functional resin and hybrid or ultramicro inorganic filler composition, in addition, there are photosensitizers, reducing agents, polymerization inhibitors, such as toner . Visible light curing device is made of tungsten halogen lamp, light pipe, switch, timer, heat sink and other components. Some are equipped with filters. Wave length is generally in the 450 ~ 550nm range, the effective wavelength 470 ~ 510nm. Light conduction liquid or fiberglass light pipe, quartz rods and so on. Voltage changes on the light intensity
