随着对复合树脂无机填料的粒度、含量、固化形式和色泽的不断改进,目前复合树脂~([1])已被认为是一种较理想的牙体修复材料,通过粘接技术粘附到窝洞内,使其洞形预备比银汞合金修复更加简单快捷,同时保留更多健康牙体组织。粘接剂发展至今已经出现八代产品,第一、二代粘接剂的作用在于促进粘接剂与牙本质活性基团的化学结合,粘接强度不高~([2])。随着微机械固位机制的提出,第三、四代粘 With the continuous improvement of the particle size, content, curing form and color of the composite resin inorganic filler, the current composite resin ~ ([1]) has been considered as a more ideal dental restoration material, adhered to Nest hole, making it more simple and efficient preparation of the hole than the amalgam repair, while retaining more healthy tooth tissue. Eight generations have emerged in the development of adhesives. The first and second generation adhesives have the effect of promoting the chemical bonding between adhesives and dentin active groups, and the bonding strength is not high. [2] With the proposed mechanism of micro-mechanical retention, the third and fourth generation sticky
