Abstract

Purpose: To investigate the effect of painless low-power Er:YAG laser irradiation of conventional and polymer-infiltrated ceramic network (PICN) type CAD-CAM resin-based composites (RBCs) on resin bonding.

Methods: An Er:YAG laser system, phosphoric acid etchant, universal adhesive, RBC, and two types of CAD-CAM RBC block were used. Microtensile bond strength, fracture mode, scanning electron microscopy (SEM) observations of bonding interfaces and CAD-CAM surfaces, and surface roughness of ground and pretreated surfaces were investigated. As pretreatment methods, low-power Er:YAG laser irradiation and air-abrasion with alumina particles were used.

Results: The effect of low-power Er:YAG laser irradiation of CAD-CAM RBCs on bonding to repair resin varied depending on the type of CAD-CAM RBCs.

Clinical significance: The low-power Er:YAG laser irradiation of the conventional CAD-CAM RBCs was shown to be effective as a surface pretreatment for resin bonding, while the laser irradiation of PICN-type CAD-CAM RBCs was not effective.

低功率 Er:YAG 激光照射 CAD-CAM 树脂基复合材料对树脂粘合的影响。

目的：研究无痛低功率 Er:YAG 激光照射传统型和聚合物浸润陶瓷网络（PICN）型 CAD-CAM 树脂基复合材料（RBC）对树脂粘接的影响：方法：使用 Er:YAG 激光系统、磷酸蚀刻液、通用粘合剂、RBC 和两种 CAD-CAM RBC 块。研究了微拉伸粘接强度、断裂模式、粘接界面和 CAD-CAM 表面的扫描电子显微镜（SEM）观察结果以及研磨表面和预处理表面的表面粗糙度。预处理方法包括低功率 Er:YAG 激光照射和氧化铝颗粒气磨：结果：低功率 Er:YAG 激光照射 CAD-CAM RBC 对修复树脂粘接的影响因 CAD-CAM RBC 的类型而异：临床意义：对传统的 CAD-CAM RBC 进行低功率 Er:YAG 激光照射可以有效地对树脂粘接进行表面预处理，而对 PICN 型 CAD-CAM RBC 进行激光照射则效果不佳。
