空气磨损似乎是强制性的持久树脂粘结氧化锆陶瓷。空气磨损可能通过产生表面缺陷而损害陶瓷强度。因此，省略空气磨损或使用降低的空气压力似乎是可取的。我们测试了零假设，即省略空气磨损或使用降低的空气压力不会影响氧化锆陶瓷粘结，而与使用底漆无关。测试了三种机械表面条件（抛光，0.05或0.25 MPa下的空气研磨）和4种底漆条件。在不同的表面处理后，氧化锆陶瓷试样进行了粘结，并在水储存3天或150天后进行了拉伸粘结强度评估，并进行了额外的37，500次人工老化热循环。省略空气磨损导致剥离过程中独立的使用底漆人工老化。空气研磨和底漆的组合显著改善了树脂与氧化锆陶瓷的长期结合。使用低压空气研磨，只要涂敷足够的粘合剂底漆，表面粗糙度降低而不影响长期粘合强度。
Air-abrasion seems to be mandatory for durable resin bonding to zirconia ceramic. Air-abrasion might compromise the ceramic strength by creating surface defects. Therefore, omitting air-abrasion or using reduced air-pressure seems desirable. We tested the null hypotheses that omitting air-abrasion or using reduced air-pressure does not affect zirconia ceramic bonding independent of using primers. Three mechanical surface conditions (polished, air-abraded at 0.05 or at 0.25 MPa) and 4 priming conditions were tested. After different surface conditioning, zirconia ceramic specimens were bonded, and tensile bond strengths were evaluated after water storage for 3 days or for 150 days with additional 37,500 thermal cyclings for artificial aging. Omitting air-abrasion resulted in debonding during artificial aging independent of using primers. The combination of air-abrasion and priming improved long-term resin bonding to zirconia ceramic significantly. With low-pressure air-abrasion, surface roughness was reduced without affecting long-term bond strength, provided that adequate adhesive primers were applied.
