不同粘接材料及表面处理方法对瓷与托槽粘结强度的影响

Different adhesive materials and different surface treatment on the porcelain and the influence of orthodontic bracket bonding strength

目的:探讨不同粘接材料及不同表面处理方法对瓷与托槽粘结强度的影响。方法:将烤瓷试样按喷砂+氢氟酸酸蚀+陶瓷偶联剂、喷砂+氢氟酸酸蚀、喷砂+陶瓷偶联剂分成A、B、C三组进行不同方法表面处理,然后分别用3M光固化型、3M化学固化型、西湖巴尔化学固化型、京津化学固化型釉质粘结剂粘结金属托槽。力学材料试验机上剪切法去除托槽,测定各自的抗剪切强度,并用ARI积分法记录托槽去除后瓷面上粘接剂残留指数,以上所有数据进行统计分析。结果:无论抗剪切强度还是瓷面上粘接剂残留指数,A、B组均大于C组(P<0.05),A、B组间无差异(P>0.05);3M光固化型粘结剂大于3M化学固化型、杭州西湖化学固化型粘结剂(P<0.05),3M化学固化型、杭州西湖化学固化型两种粘结剂间无差异(P>0.05),3M化学固化型、杭州西湖化学固化型两种粘结剂大于京津化学固化型粘结剂(P<0.05),3M光固化型粘结剂显著大于京津化学固化粘结剂(P<0.01)。结论:喷砂结合氢氟酸酸蚀瓷面粘结托槽效果较好,陶瓷偶联剂并不能增加其粘结强度;3M光固化粘结剂在瓷面上粘结效果最好,3M化学固化粘结剂、杭州西湖化学固化粘结剂次之,推荐使用3M光固化型粘结剂。

Objective：to study the different adhesive materials and ceramic surface treatment on porcelain and the influence of orthodontic bracket bonding strength. Method：porcelain samples by sandblasting ＋hydrofluoric acid pickling ＋ceramic coupling agent, sandblasting＋hydrofluoric acid pickling,sand blasting,ceramic coupling agent is divided into three groups of different surface treatment, then respectively with 3 m light chemical solidifying,3 m, west lake barr chemical solidification, the Beijing and tianjin chemical solidifying four adhesive bonding metal braces. Mechanical removal of braces sheared material testing machine, testing their shear strength,braces are removed by ARI integral method porcelain surface adhesive residue index and above all the data statistical analysis. Result：both the shear strength and adhesive residue index and porcelain surface A and B group were greater than C group（P＆lt;0.05）,A and B group no difference（P ＆gt;0.05）. 3 m uv-curable adhesive is greater than 3 m chemical solidifying,hangzhou west lake chemical curing adhesive （P ＆lt;0.05）,3 m chemical solidifying, hangzhou west lake chemical curing two binder no difference （P 〉0.05）,3 m chemical solidifying, hangzhou west lake chemical curing two binder is greater than the Beijing and tianjin chemical curing adhesive（P 〈0.05）,3 m light curing adhesive significantly greater than the Beijing and tianjin chemical curing adhesive （P 〈0.01）. Conclusion：the combination of sandblasting hydrofluoric acid etched enamel surface bonding slot effect is good ,the ceramic coupling agent does not increase the bond strength;3 m uv-curable adhesive bonded on the surface of the porcelain works best,3 m chemical curing adhesive chemical adhesive curing times, hangzhou west lake,it is recommended to use 3 m uv-curable adhesive.
