Abstract

Objective: The aim of this study is to analyze the effect of laser treatment on surface morphology of restorative materials. Materials and Methods: The samples included 19 porcelain ceramics (Group P), 10 half yttrium stabilized zirconia (Y-TZP) and half porcelain (Group ZP), and 13 Y-TZP ceramic (Group Z). Pilot study was applied on the prepared samples to determine the effectiveness of hydroxyapatite or graphite powder before surface treatment. Following the pilot study, three laser systems were treated over all ceramic surfaces and scanning electron microscope (SEM) images were taken to do topographic analysis of the samples. Results: According to the results of pilot study; surfaces of zirconia, porcelain, and zirconia-porcelain samples were covered with graphite powder and then treated by CO 2 laser, erbium:Yttrium-aluminum-garnet (Er:YAG) and neodymium:YAG (Nd:YAG) laser. SEM observations were reported for all laser types and all laser parameters that were chosen. Conclusion: The three types of laser products; CO 2 , Er:YAG, and Nd:YAG are also effective on different output powers on different types of restorative materials.

三次激光处理修复材料表面形貌分析的SEM评价
目的:分析激光治疗对修复材料表面形态的影响。材料与方法:样品包括19种陶瓷(P组),10种半钇稳定氧化锆(Y-TZP)和半瓷(ZP组),13种Y-TZP陶瓷(Z组)。对制备的样品进行中试研究,以确定表面处理前羟基磷灰石或石墨粉的有效性。在初步研究之后,对所有陶瓷表面进行了三种激光系统处理,并拍摄了扫描电子显微镜(SEM)图像对样品进行地形分析。结果:根据前期研究结果;用石墨粉覆盖氧化锆、陶瓷和氧化锆-瓷样品的表面,然后用co2激光、铒钇铝石榴石(Er:YAG)和钕钇石榴石(Nd:YAG)激光进行处理。报告了所选择的所有激光类型和所有激光参数的扫描电镜观察结果。结论:三类激光产品;CO 2、Er:YAG和Nd:YAG对不同类型的修复材料的输出功率也不同。
