对于牙体大面积缺损,树脂嵌体修复是近年来一种新型修复技术,与树脂直接充填修复相比较,树脂在体外经二期固化处理后,抗压强度、硬度、耐磨性、恢复邻接关系等方面具有较好的临床效果[1]。Ceramage聚合瓷是近年来一种新型瓷化树脂,主要用于制作冠、贴面、嵌体、高嵌体等。然而嵌体的边缘线较长,发生微渗漏的可能性较大,且不同树脂嵌体材料与牙体间微渗漏的程度也不同[2]。本研究通过比较Ceramage聚合瓷嵌体和纳米树脂嵌体材料
For large area defects of the tooth, resin inlay repair is a new repair technique in recent years. Compared with resin direct filling and repairing, the compressive strength, hardness and abrasion resistance of resin resumed adjacency Relationship and so has a good clinical effect [1]. Ceramage polymer porcelain is a new type of porcelain resin in recent years, mainly used for making crown, veneer, inlays, inlays and so on. However, the inlay margin is longer and the possibility of microleakage is greater, and the degree of microleakage between different resin inlay materials and the tooth is also different [2]. This study compares Ceramage polymer inlays and nano-resin inlay materials
