目的采用3种不同的粘接剂对CAD/CAM树脂与3种树脂复合骨水泥的粘接性能进行评价（剪切粘结强度（SBS，n=180）、拉伸粘结强度（TBS，n=180）和粘附功（WA，n=60）），进一步分为四种预处理方法（VP连接（VP）、BPO. link（VL）、Clearfil陶瓷底漆（CP）和无预处理（CG））和三种骨水泥（RelyX ARC、Variolink II和Clearfil SA骨水泥）。每个亚组包含15个标本。在24 h H2O/37 ℃ + 5000次热循环（5/55 ℃）后测量SBS和TBS，并评估失效类型。测定预处理CAD/CAM树脂和非聚合树脂复合水门汀的WA。结果在SBS和TBS测试中，CG和CP预处理组（不考虑树脂复合骨水泥）以及VP预处理组（Clearfil SA骨水泥）均未显示出粘结。然而，CG结合RelyX ARC显示TBS为5.6 +/- 1.3 MPa。一般而言，用VL处理的组观察到最高的粘合强度。CG和VL预处理组的WA低于VP或CP处理组。总体而言，SBS和TBS在各组的数值范围内显示出相似的趋势。WA结果与SBS/TBS结果不具有可比性，因此没有结论。临床相关性对于XHIP-CAD/CAM树脂的临床使用，粘结表面应另外用Aluminum预处理。链接作为粘合剂。
Objectives The aim of this study was to assess the bonding properties between CAD/CAM resin and three resin composite cements combined with different bonding agents using three test methods.Materials and methods Four hundred twenty CAD/CAM resin substrates were fabricated and divided into three test methods (shear bond strength (SBS, n=180), tensile bond strength (TBS, n=180) and work of adhesion (WA, n=60)), further into four pretreatment methods (VP connect (VP), visio. link (VL), Clearfil Ceramic Primer (CP) and no pretreatment (CG)) and three cements (RelyX ARC, Variolink II and Clearfil SA Cement). Each subgroup contained 15 specimens. SBS and TBS were measured after 24 h H2O/37 degrees C+ 5000 thermal-cycles (5/55 degrees C) and failure types were assessed. WA was determined for pretreated CAD/CAM resin and non-polymerized resin composite cements. Data were analysed with Mann-Whitney U, Kruskal-Wallis H, Chi2 and Spearman's Rho tests.Results Within SBS and TBS tests, CGs and groups pretreated with CP (regardless of resin composite cements), and VP pretreated with Clearfil SA Cement showed no bond. However, CG combined with RelyX ARC showed a TBS of 5.6 +/- 1.3 MPa. In general, highest bond strength was observed for groups treated with VL. CG and groups pretreated using VL showed lowerWA than the groups treated with VP or CP.Conclusions Measured TBS values were higher than SBS ones. In general, SBS and TBS showed similar trends for the ranges of the values for the groups. WA results were not comparable with SBS/TBS results and admitted, therefore, no conclusions on it. Clinical relevance For a clinical use of XHIP-CAD/CAM resin, the bond surface should be additionally pretreated with visio. link as bonding agent.
