This study was to determine the shear bond strengths of Ni-Cr alloy to Ni-Cr alloy (Group I), Ni-Cr alloy to enamel (Group II), and Ni-Cr alloy to dentin (Group III) using Imperva Dual, DC Metabond, All-Bond, Geristore, and Panavia. All bonded specimens were thermocycled 2000 x (5 degrees C-55 degrees C) after 24 hours and subjected to shear bond testing on a Universal Instron Testing Machine. In all groups of the study, Imperva Dual and CB Metabond had significantly (p < .05) higher bond values than Panavia.
本研究旨在使用Imperva Dual、DC Metabond、All-Bond、Geristore和Panavia测定镍铬合金与镍铬合金(第一组)、镍铬合金与牙釉质(第二组)以及镍铬合金与牙本质(第三组)之间的剪切粘结强度。所有粘结标本在24小时后进行2000次(5摄氏度至55摄氏度)热循环,并在万能英斯特朗试验机上进行剪切粘结测试。在该研究的所有组中,Imperva Dual和CB Metabond的粘结值显著高于Panavia(p <.05)。
