The purpose of the current study was to develop a light source as well as a light-curing unit for polymerization of indirect composites.1. A reflector was designed using a glass substructure instead of a metallic one. The inner surface of the reflector was coated with varying metal oxides. By changing the composition and thickness of the coating layers, degree of the reflection could be changed.2. A metal halide light source was constructed after preparation of an arc tube and a reflector. A laboratory light-curing unit was next fabricated. The MIII unit was especially designed for laboratory polymerization of indirect veneering and inlay/onlay composites and opaque resins. The unit was equipped with two halogen lamps and a metal halide lamp.3. Depth of cure of an indirect composite was determined to evaluate curing performance of the MIII unit. A xenon curing unit (UXS) was used as the reference unit. Depth of cure after specific light exposure period was as follows. Exposure period (s), MIII DC (mm): UXS DC (mm): 20 s=2.00:l.24. 30 s2.13:l.55. 60 s=2.50:l.95. 90 s=3.04:2.26.4. Knoop hardness number of an indirect composite (Sinfony) was determined, and the results were KHN=24 for the Visio units, and KHN=40 for the MIII unit. Significant difference was found between the two values.

当前研究的目的是开发一种用于间接复合材料聚合的光源和光固化装置。 1．反射器的设计使用玻璃底座而不是金属底座。反射器的内表面涂有不同的金属氧化物。通过改变涂层的成分和厚度，可以改变反射的程度。 2．制备好电弧管和反射器后构建金属卤化物光源。接下来制造了实验室光固化装置。 MIII 装置专为间接饰面、镶嵌/高嵌复合材料和不透明树脂的实验室聚合而设计。该装置配备有两个卤素灯和一个金属卤化物灯。3．确定间接复合材料的固化深度以评估 MIII 单元的固化性能。使用氙气固化装置（UXS）作为参考装置。特定曝光时间后的固化深度如下。曝光时间（秒），MIII DC（毫米）：UXS DC（毫米）：20秒=2.00：l.24。 30 s2.13:l.55。 60秒=2.50:l.95。 90秒=3.04:2.26.4。测定了间接复合材料（Sinfony）的努氏硬度值，Visio 单位的结果为 KHN=24，MIII 单位的结果为 KHN=40。两个值之间发现显着差异。
