In vivo Study of Adaptation of Adhesive Composites

本研究的目的是评估新开发的牙用复合材料在体内和体外的边缘微渗漏和适应性。本研究使用的材料是三种修复复合材料，分别是Photo Anterior/Liner Bond System， PhotoClearfil Bright/Photo Bond和Clearfil F II/ New Bond。用这些材料修复提取的人类前磨牙，并对其进行负荷循环和热循环后的边际微渗漏和适应性评估。然后，用这些复合材料修复猴子的牙齿。修复后7天和180 d处死，拔牙，评估边缘微漏和适应情况。在体外和体内实验中，光前/衬里结合系统在所有材料中表现出最小的边际微漏和最好的腔适应性。结果表明，由CA剂、SA底漆和保护剂组成的复合材料对腔体的附着力起重要作用。

The purpose of this study was to evaluate marginal microleakage and adaptation of newly developed dental composite in vivo and in vitro. The materials used in this study were three restorative composites, Photo Anterior/Liner Bond System, PhotoClearfil Bright/Photo Bond and Clearfil F II/ New Bond. Extracted human premolars restored with these materials were evaluated marginal microleakage and adaptation after load cycled or thermocycled. Then, monkey teeth were restored with these composites. The animals were sacrificed 7 and 180 days after restoration and the teeth were extracted and evaluated marginal microleakage and adaptation. Both in vitro and in vivo, Photo Anterior/Liner Bond System showed the least marginal microleakeage and best adaptation to the cavity in all materials. The results suggests that CA agent, SA primer and protect Liner in which the Liner Bond System consists contribute the adhesion of the composite to the cavity.
