Resin bonding to a glass-infiltrated aluminum oxide ceramic (In-Ceram) cannot be achieved by the methods commonly used for conventional silica-based dental ceramics. This study evaluated the durability of alternative methods of adhesive bonding to In-Ceram ceramic. The tensile bond strength of six bonding systems to In-Ceram ceramic was tested after up to 150 days of storage in isotonic artificial saliva solution and thermal cycling. Sandblasting alone or additional use of a silane did not result in a durable bond of a conventional BIS-GMA composite resin to In-Ceram ceramic. A durable bond to In-Ceram ceramic was achieved with a combination of tribochemical silica coating and conventional BIS-GMA composite resin or with the combination of sandblasting and a composite resin modified with a phosphate monomer. These two chemomechanical bonding methods appeared suitable for clinical bonding of In-Ceram ceramic restorations. A delayed degradation in bond strength was recorded for the combination of thermal silica coating and a conventional BIS-GMA composite resin; no reduction was found after 30 days, but there was a pronounced decrease after 150 days. This degradation indicated that extended storage in a wet environment was needed in laboratory tests to evaluate the durability of chemical bonds.
树脂与玻璃渗透氧化铝陶瓷（In-Ceram）的粘结无法通过常规用于传统二氧化硅基牙科陶瓷的方法来实现。本研究评估了粘结In-Ceram陶瓷的替代方法的耐久性。在等渗人工唾液溶液中储存长达150天并进行热循环后，测试了六种粘结系统与In-Ceram陶瓷的拉伸粘结强度。单独喷砂或额外使用硅烷并不能使传统双甲基丙烯酸缩水甘油酯（BIS-GMA）复合树脂与In-Ceram陶瓷形成持久的粘结。通过摩擦化学二氧化硅涂层与传统BIS-GMA复合树脂的组合或喷砂与用磷酸盐单体改性的复合树脂的组合，可实现与In-Ceram陶瓷的持久粘结。这两种化学机械粘结方法似乎适用于In-Ceram陶瓷修复体的临床粘结。对于热二氧化硅涂层与传统BIS-GMA复合树脂的组合，记录到粘结强度的延迟降解；30天后未发现降低，但150天后有明显下降。这种降解表明在实验室测试中需要在潮湿环境中延长储存时间以评估化学键的耐久性。
