An argon ion laser has some interesting characteristics for light-activating of composite resin filling materials. The laser light is monochromatic and coherent, and it's intensity is stable over a long period of time. Furthermore, there is only few decreasing of light intensity when increasing the distance from a light source. So, the usage of an argon ion laser might provide many clinical advantages, especially in area of the complicated anatomical forms where the light could not be brought into the proximity to the surface of the resin.The first step in this investigation was accomplished to build up and to improve the argon ion laser unit to be suitable for curing composite resins. Secondary, accomplished experiments were estimated the curing ability compared with the commercially available light activator. It was determined that a significantly greater degree of polymerization was achievable following argon lasing compared to exposure with conventional light activators. And higher bond strengths were obtained with argon lasing in spite of increasing distance from the irradiation surface. In final step in this investigation, the clinical performance of this system was planned in clinics.

氩离子激光器在复合树脂填充材料的光活化方面具有一些有趣的特性。激光是单色的、相干的，在很长一段时间内强度是稳定的。此外，随着与光源距离的增加，光强的下降幅度很小。因此，使用氩离子激光可能会提供许多临床优势，特别是在复杂的解剖形式的区域，光不能被带到树脂表面附近。本研究的第一步是建立和改进氩离子激光装置，使其适合于固化复合树脂。其次，将完成的实验与市售的光活化剂进行了固化能力的比较。结果表明，与使用传统的光激活剂相比，氩气激光可以实现更大程度的聚合。随着距离辐照表面的距离增大，氩激光的结合强度增大。在本次调查的最后一步，该系统的临床性能计划在诊所。
