摘要： 目的研究不同处理方式对树脂纳米瓷(LAVA Ultimate)与树脂水门汀粘接后剪切强度的影响。方法本次实验分为喷砂实验和粘接实验两部分。将LAVA Ultimate切削成大小约 6 mm×6 mm,高度约为2 mm的样本80片,依照不同的喷砂时间和喷砂气压随机分为4组,每组10个试件,使用3M Single Bond Universal+3M RelyX Ultimate与纳米树脂柱粘接后在万能试验机上测试断裂载荷,计算剪切强度,选出最高组。同等喷砂条件下40个样本随机分为A(Single Bond Universal(3M)+RelyX Ultimate(3M)) ,B (Porcelain Primer(Bisco)+ All-bond Universal(Bisco)+RelyX Ultimate(3M))与纳米树脂柱进行粘接。粘接后再分成两个亚组,分别进行冷热循环5 000次和恒温水浴24 h。在万能试验机上测试断裂载荷,计算剪切强度,采用单因素方差分析对数据进行统计分析。结果单因素方差分析结果表明不同喷砂条件的分组对剪切强度差异有统计学意义(第2组和第4组)(P=0.037);冷热循环后,A组和B组试件的剪切强度均有明显下降(P=0.003,P<0.01);A、B组不同粘接方式的剪切强度差异无统计学意义(P=0.062,P=0.671)。结论 0.2 MPa压力下喷砂14 s可明显提高树脂纳米瓷与树脂水门汀的剪切强度;冷热循环会明显降低剪切强度;粘接方式对剪切强度无明显影响。

Abstract: Objective To study the influence of different treatment methods on the shear strength of resin nano-ceramics (LAVA Ultimate) after bonding. Methods The LAVA Ultimate was cut into 80 samples with a size of about 6 mm×6 mm and a height of 2 mm. According to different sandblasting time and pressure, the samples were randomly divided into 4 groups with 10 specimens in each group. The fracture load was tested on the Universal testing machine after the 3M Single Bond Universal+3M RelyX Ultimate was bonded to the nano resin column, and the shear strength was calculated to select the highest group. Under the same blasting conditions, 40 samples were randomly divided into A (3M Single Bond Universal+3M+RelyX Ultimate), B (Porcelain Primer (Bisco)+All-bond Universal (Bisco) Relyx Ultimate (3M)) and nano resin columns for bonding. After bonding, they were divided into two subgroups, which were subjected to 5 000 cooling and heating cycles and a constant temperature water bath for 24 h, respectively. The breaking load was tested on a universal testing machine. The shear strength was calculated, and the data were statistically analyzed using one-way ANOVA. Results Results of one-way ANOVA showed that there were significant differences in shear strength between different sandblasting conditions (group 2 and group 4) (P=0.037). After hot and cold cycling, the shear strength of group A and group B decreased significantly (P=0.003, P<0.01). There was no significant difference in shear strength between groups A and B with different bonding modes (P=0.062). Conclusion The shear strength of resin nano porcelain and resin cement can be significantly improved by sandblasting at 0.2 MPa for 14s, and can be significantly reduced by cooling and heating cycles. The bonding mode has no obvious effect on the shear strength.
