目的
该研究检查了热循环后两种树脂义齿牙齿和浇注型义齿基托树脂之间的粘合强度。假牙未经处理、用强效剂制备或用溶剂二氯甲烷处理。
材料和方法
传统的假牙和交联假牙被粘合到浇注型假牙基托树脂上。以45度角向每颗牙齿的腭面施加压缩载荷直至断裂。牙齿要么经过热循环，要么未经热循环。还对烤瓷牙进行了测试以进行比较。
结果
传统树脂牙和交联义齿之间的粘合强度没有显着差异。热循环显着降低了两种树脂牙的粘合强度，但对烤瓷牙没有影响。二氯甲烷的应用显着提高了两种树脂牙齿在热循环之前或之后的粘合强度。
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 resin denture teeth and a pour-type denture base resin after thermocycling. The denture teeth were untreated, prepared with diatorics, or treated with a solvent, dichloromethane.
MATERIALS AND METHODS
Conventional denture teeth and crosslinked denture teeth were bonded to a pour-type denture base resin. Compressive load was applied at 45 degrees on the palatal surface of each tooth until fracture. The teeth were either thermocycled or not thermocycled. Porcelain teeth were also tested for comparison.
RESULTS
There was no significant difference in bond strength between the conventional resin teeth and the crosslinked denture teeth. Thermocycling significantly decreased the bond strength of the 2 types of resin teeth but had no effect on porcelain teeth. The application of dichloromethane significantly improved the bond strength of the 2 types of resin teeth either before or after thermocycling.
CONCLUSION
It is recommended that dichloromethane be applied on the denture teeth ridge-lap area prior to denture base processing.
