Abstract

Assess the effect of applying a low viscosity resin before placing ceramic restoration with two different luting agent.

Twenty slices from IPS e.max CAD (Ivoclar Vivadent) were fired and assigned to 5 treatment surface groups; E: hydrofluoric acid (HF); E/S: HF-etching?+?silane (20?s); E/S+: HF-etching?+?silane (60?s); S: silane (20?s); S+: silane (60?s). Before building the cylinder with regular or flowable composite resin for the SBS test, half of each treatment surface group received adhesive (Optibond FL bottle #2), and the other half no adhesive. The SBS test was performed after 24?h. Statistical analysis was performed using multifactorial analyses of variance Two-way ANOVA. The Tukey HSD test was used to test the average values of all groups. The significance level adopted in all analyses was?≤?0.05 (p?<?0.05).

Groups E/S and E/S+, with flowable?+?adhesive and E/S with regular composite resin?+?adhesive, showed the highest SBS values (22.05, 18.91 and 21.06?MPa respectively), followed by group E with or without adhesive, for both luting agent. The lowest bond strength was observed when the silane was applied alone, independent of the adhesive coat and luting agent (0.65–5.55?MPa). When the adhesive was omitted, flowable presented high bond strength compared to composite resin in groups ES and ES+.

The low viscosity resin in the etched and silanized ceramic surface is important to obtain high SBS values.

CAD/CAM二硅酸锂修复体与常规可流动复合树脂的粘接

在用两种不同的修复剂放置陶瓷修复体之前，评估使用低粘度树脂的效果。取IPS e.max CAD (Ivoclar Vivadent)切片20片，分为5个处理面组;E:氢氟酸(HF);E / S: HF-etching + ?硅烷(20);E / S +: HF-etching + ?硅烷(60年代);S:硅烷(20s);S+:硅烷(60? S)。在用常规或可流动的复合树脂构建用于SBS测试的圆柱体之前，每个处理表面组的一半使用粘合剂(Optibond FL瓶#2)，另一半不使用粘合剂。24 h后进行SBS试验。统计分析采用多因素方差分析，双因素方差分析。采用Tukey HSD检验对各组平均值进行检验。所有分析采用的显著性水平为?≤?0.05 (p?<?0.05)。E/S组和E/S+组，具有可流动的?胶粘剂和E/S与常规复合树脂?SBS值最高，分别为22.05、18.91和21.06?(MPa)，其次是有胶或无胶的E组。单独使用硅烷时，与涂层和粘结剂无关，其粘结强度最低(0.65 ~ 5.55 MPa)。当不添加粘合剂时，与ES组和ES+组相比，flowable的结合强度更高。蚀刻和硅化陶瓷表面的低粘度树脂是获得高SBS值的重要因素。
