目标.本体外研究的目的是使用五种类型的表面处理方法评估粘合剂粘合系统与非晶和结晶PEKK和纤维增强PEEK的粘合强度和耐久性。对每种材料的150个样本进行机械和化学处理，用Multilink Automix粘合到树脂玻璃管上，填充Multicore Flow，并在37 ℃的水中储存3、30和150天。在拉伸粘合强度测试（TBS）之前，将长期储存系列在5至55 ℃之间热循环10，000次（30天）或37，500次（150天）。使用Kruskal-Wallis和Wilcoxon检验进行统计分析，多重检验采用Bonferroni-Holm校正（α = 0.05）。纤维增强PEEK在所有五个调节组和所有三个储存时间中表现出比结晶和非晶PEKK更高的粘合强度，后者显示出最低的TBS。在用二氧化硅涂层和底漆（Rocatec Soft、Monobond Plus、Luxatemp Glaze 81 Bond; TBS高达23.6 MPa）调节后实现了最高TBS。调节方法对无定形和结晶PEKK以及纤维增强PEEK的粘合强度具有显著影响。(C)2013年牙科材料学院。由爱思唯尔有限公司出版。保留所有权利。
Objectives. The purpose of this in vitro study was to evaluate the bond strength and durability of adhesive bonding systems to amorphous and crystalline PEKK and fiber-reinforced PEEK using five types of surface conditioning methods.Methods. One hundred and fifty specimens of each material were conditioned mechanically and chemically, bonded with Multilink Automix to Plexiglas tubes, filled with Multicore Flow, and stored in water at 37 degrees C for 3,30 and 150 days. The long-term storage series were thermal cycled between 5 and 55 degrees C for 10,000 times (30 days) or for 37,500 times (150 days) prior to tensile bond strength test (TBS). Statistical analysis was performed using Kruskal-Wallis and Wilcoxon tests with a Bonferroni-Holm correction for multiple testing (alpha = 0.05).Results. Fiber-reinforced PEEK exhibited higher bond strengths in all five conditioning groups and at all three storage times than crystalline and amorphous PEKK, which showed lowest TBS. Highest TBS was achieved after conditioning with silica coating and priming (Rocatec Soft, Monobond Plus, Luxatemp Glaze 81 Bond; TBS up to 23.6 MPa).Significance. The conditioning method has a significant influence to the bond strength of the bonding to the amorphous and crystalline PEKKs and fiber-reinforced PEEKs. (C) 2013 Academy of Dental Materials.
