This study evaluated shear bond strengths of a layering indirect composite material to a zirconia framework material treated with tribochemical silica coating. Zirconia disks were divided into two groups: ZR-PRE (airborne-particle abrasion) and ZR-PLU (tribochemical silica coating). Indirect composite was bonded to zirconia treated with one of the following primers: Clearfil Ceramic Primer (CCP), Clearfil Mega Bond Primer with Clearfil Porcelain Bond Activator (MGP+Act), ESPE-Sil (SIL), Estenia Opaque Primer, MR. Bond, Super-Bond PZ Primer Liquid A with Liquid B (PZA+PZB), and Super-Bond PZ Primer Liquid B (PZB), or no treatment. Shear bond testing was performed at 0 and 20,000 thermocycles. Post-thermocycling shear bond strengths of ZR-PLU were higher than those of ZR-PRE in CCP, MGP+Act, SIL, PZA+PZB, and PZB groups. Application of silane yielded better durable bond strengths of a layering indirect composite material to a tribochemically silica-coated zirconia framework material.
本研究评估了一种分层间接复合材料与经摩擦化学二氧化硅涂层处理的氧化锆框架材料之间的剪切粘结强度。将氧化锆盘分为两组：ZR - PRE（空气颗粒研磨）和ZR - PLU（摩擦化学二氧化硅涂层）。间接复合材料粘结到用以下底漆之一处理过的氧化锆上：Clearfil陶瓷底漆（CCP）、带有Clearfil瓷粘结活化剂的Clearfil Mega Bond底漆（MGP + Act）、ESPE - Sil（SIL）、Estenia不透明底漆、MR. Bond、Super - Bond PZ底漆液A与液B（PZA + PZB）以及Super - Bond PZ底漆液B（PZB），或者不进行处理。在0和20000次热循环后进行剪切粘结测试。在CCP、MGP + Act、SIL、PZA + PZB和PZB组中，ZR - PLU的热循环后剪切粘结强度高于ZR - PRE。硅烷的应用使分层间接复合材料与经摩擦化学二氧化硅涂层处理的氧化锆框架材料之间具有更好的持久粘结强度。
