This study evaluated the shear bond strength (SBS) of 4 different retentive materials for the chairside pickup of dental implant attachments. Shear force was applied to determine the SBS of each material to denture acrylic resin. The difference between SBSs of polymethyl methacrylate and UBAR (claimed to bond to metal) to metal housings was also evaluated. There were no statistically significant differences among the SBSs of Jet Denture Repair Acrylic, EZ PickUp, and UBAR, but Quick Up had an SBS that was significantly lower than that of the other 3 materials. In addition, UBAR had a higher SBS to metal housings than did processed polymethyl methacrylate.
本研究评估了4种不同固位材料用于椅旁取件式牙种植体附件的剪切粘结强度（SBS）。通过施加剪切力来确定每种材料与义齿丙烯酸树脂之间的SBS。还评估了聚甲基丙烯酸甲酯和UBAR（声称可粘结至金属）与金属外壳之间SBS的差异。Jet义齿修复丙烯酸树脂、EZ PickUp和UBAR的SBS之间无统计学显著差异，但Quick Up的SBS显著低于其他3种材料。此外，UBAR与金属外壳之间的SBS高于加工后的聚甲基丙烯酸甲酯。
