摘要/Abstract

摘要： 目的　通过研究新型流体树脂材料DMG constic与牙本质和临时冠材料的粘结性能，分析实验中粘结性能的相关数据，为临床上材料的使用提供参考。方法　采用微拉伸测力仪测定材料与牙本质和临时冠材料粘结微拉伸强度，应用扫描电镜观察材料断裂界面微观形貌并判断断裂方式。结果　新型树脂DMG constic与牙本质的粘结强度与3M Z350流动树脂，经t检验存在差异性(P <0. 05)，但能够满足临床的需要；新型树脂DMG constic与临时冠粘结强度，经t检验无显著差异性(P>0. 05)；两组实验材料的断裂方式均以界面断裂为主。结论　免酸蚀免粘结新型流体树脂材料简化了口腔操作程序，能够满足临床的多种需要。

Abstract: Objective　To analyze bond properties of flowable resin Constic, and to provide laboratory evidence for the application of clinical material. Methods The micro-tensile bond strengths between flowable resin and dentin, flowable resin and temporary crown material were measured by micro tensile force meter. Surface morphology was studied by scanning electron，and the modes of failure were judged. Results The dentin micro-tensile bond strengths of Constic resin and Z350 XT were (20.60±4.09) MPa, (31.23±5.66) MPa, respectively(t=7.943, P<0. 05). Temporary crown material bond strength of Constic was (53.67±8.94) MPa, while bond strength between temporary crown material was (59.52±4.24) MPa (t=1.388, P>0.05). The fracture sites of most samples were at interface. Conclusion As a self-etching and self-adhesive system, Constic simplifies clinical procedure, and it is potential for multiple clinical use.
