目的
该研究检查了 2 种假牙牙齿和 3 种假牙基托树脂之间的粘合强度。假牙未经处理、用强效剂制备或用二氯甲烷（一种溶剂）处理。
材料和方法
传统的假牙和交联假牙与热固化假牙基托树脂、微波固化假牙基托树脂或浇注型假牙基托树脂粘合。以45度角向每颗牙齿的腭面施加压缩载荷直至断裂。
结果
传统树脂牙齿比交联义齿牙齿具有更高的粘合强度。热固化义齿基托树脂的粘合强度明显超过微波固化义齿基托树脂。两种材料均优于浇注型树脂。与使用二氯甲烷相比，使用二氯甲烷可以显着更好地提高粘合强度。
结论
建议在义齿基托处理之前将二氯甲烷涂在义齿牙槽嵴搭接区域。
PURPOSE
The study examined the bond strength between 2 types of denture teeth and 3 denture base resins. The denture teeth were untreated, prepared with diatorics, or treated with dichloromethane, a solvent.
MATERIALS AND METHODS
Conventional denture teeth and cross-linked denture teeth were bonded to either a heat-cured denture base resin, a microwave-cured denture base resin, or a pour-type denture base resin. Compressive load was applied at 45 degrees on the palatal surface of each tooth until fracture.
RESULTS
Conventional resin teeth possessed higher bond strength than cross-linked denture teeth. The heat-cured denture base resin significantly surpassed the microwave-cured denture base resin in bond strength. Both materials were better than the pour-type resin. The application of dichloromethane resulted in a significantly better improvement in bond strength compared to the use of diatorics.
CONCLUSION
It is recommended that dichloromethane be applied on the denture teeth ridge-lap area prior to denture base processing.
