摘要：

目的:通过观察Nd∶YAG激光与氢氟酸(HF)联合处理的瓷面,探讨不同瓷表面处理方法对瓷面与托槽粘结强度的影响。 方法:将48个金属烤瓷试样根据表面处理方法随机分为空白对照组、HF组、机械打磨组、0.75W激光组、1.05W激光组和1.45W激光组。经温度循环实验后,测定各组试样剪切强度和拉伸强度。 结果:各处理组试样剪切强度和拉伸强度与空白对照组比较差异有统计学意义(P<0.01),1.05W激光组和1.45W激光组试样剪切强度和拉伸强度与HF组比较差异有统计学意义(P<0.05),1.05W激光组试样剪切强度和拉伸强度均高于其他各组(P<0.05)。试样的剪切强度与拉伸强度呈正相关关系(r=0.426,P=0.000)。 结论:能量参数为1.05W的Nd∶YAG激光与HF联合处理即可获得理想的粘结强度,且剪切强度愈大其拉伸强度愈大。

Abstract:

Objective To observe the porcelain treated with Nd∶YAG laser irradiation and hydrofluoric acid(HF), and to explore the influence of integrated treatment of Nd∶YAG laser irradiation and HF etching in the bond strength of brackets to porcelain. Methods 48 metal ceramic prostheses were randomly divided into untreated control group, HF group, grooved treatment group, 0.75W laser group, 1.05W laser group, 1.45W laser group. All samples were bonded to the brackets. After temperature cycling test, the shear bond strength (SBS) and tensile bond strength (TBS)were measured. Results There were significant differences in SBS and TBS between various surface treatment groups and untreated control group (P<0.01). The SBS and TBS of brackets bonded in HF group was significantly higher than those in 1.05W laser and 1.45W laser groups (P<0.05).The SBS and TBS in 1.05W laser and 1.45W laser groups were higher than those in HF group(P<0.05). The SBS and TBS in 1.05W laser group were higher than those in other groups(P<0.05). SBS showed positive correlation with TBS(r=0.426, P=0.000). Conclusion The use of Nd∶YAG laser irradiation with the energy parameter of 1.05W and HF could increase the bonding with formation of composite resin, and the more SBS, the more TBS.
