目标。本研究的目的是评价临时树脂与聚醚醚酮(PEEK)使用不同的表面处理和处理方法的粘接强度。PEEK圆盘用600目旋转碳化硅纸抛光。将有机玻璃管填充并用临时树脂(Luxatep荧光)粘接到PEEK圆盘上，PEEK圆盘用110目氧化铝颗粒(Rocatec Pre)空气研磨，用厄瓜多尔复合修复底漆、Luxatep釉面和邦德底漆或Clearfi陶瓷底漆进行处理，或者用摩擦化学二氧化硅涂层(Rocatec Plus)和Espe Sill或Clearfi陶瓷底漆进行硅烷化处理。未作预充剂的空气研磨PEEK盘作为对照。每组8个样品在37℃的蒸馏水中保存3天，不进行热循环(TC)或150天，并在5℃至55℃之间额外进行37,500次热循环(停留时间30 S)。在万能试验机上以2 mm/min的十字头速度测试了储存后的拉伸粘结强度(TBS)。统计分析采用Kruskal-Wallis检验和Bonferroni-Holm校正的Wilcoxon秩和检验。3d后TBS为0~15.0 Mpa。人工老化超过150天后，TBS为0~12.9 Mpa。采用空气研磨和LUXTEMP釉面粘接剂预涂的方法，TBS明显高于其他方法，且经久耐用。临床上推荐在PEEK表面空气磨损后使用含甲基丙烯酸甲酯的LUXTEPEP釉面粘结剂。(C)2012年牙科材料学会。爱思唯尔有限公司出版。保留所有权利。
Objective. The purpose of the study was the evaluation of the bond strength of a provisional resin to a polyetheretherketon (PEEK) using different surface treatments and conditioning methods.Methods. PEEK disks were polished with 600 grit rotating silicon carbide papers. Plexiglas tubes were filled and bonded with a provisional resin (Luxatemp Fluorescence) to the PEEK disks which were air-abraded either with 110 mu m alumina particles (Rocatec Pre) and conditioned with the primers Ecusit Composite Repair, Luxatemp Glaze & Bond or Clearfil Ceramic Primer or they were tribochemically silica-coated (Rocatec Plus) and silanated with Espe Sil or Clearfil Ceramic Primer. Air-abraded PEEK disks without priming served as control. Subgroups of 8 specimens each were stored in distilled water at 37 degrees C either for 3 days without thermal cycling (TC) or for 150 days with additional 37,500 thermal cycles between 5 and 55 degrees C (dwell time 30 s). Following storage tensile bond strength (TBS) was tested at a crosshead speed of 2 mm/min in a universal testing machine. Statistical analysis was conducted with Kruskal-Wallis test followed by Wilcoxon rank sum test adjusted by Bonferroni-Holm.Results. After 3 days TBS ranged from 0 to 15.0 MPa. After artificial aging over 150 days TBS ranged from 0 to 12.9 MPa. Using air-abrasion and priming with Luxatemp Glaze & Bond resulted in significantly higher TBS than all other methods, which was also durable over time.Conclusion. The use of the methylmethacrylate containing primer Luxatemp Glaze & Bond after air-abrasion of PEEK surfaces can be recommended clinically as promising bonding method to PEEK.
