近十年来,高分子粘合材料在口腔科的应用,发展甚快,其种类日益增多,应用范围亦不断扩大。特别在直接粘着矫正附件,牙体缺损修复,涂膜窝沟封闭防龋等方面的应用上,巳取得了较为显著的成果。以磷酸等溶液涂敷牙面,是极大部分粘合材料使用时的首要步骤。这一过程被称为酸处理(Acid etching)。对牙面酸处理后的组织结构,物理性能的变化以及再矿物化等问题,已有大量研究报道。1974年12月,在瑞
Over the past decade, the application of polymer adhesive materials in dentistry has developed rapidly, its types are increasing, and its application range is also expanding. Especially in the application of direct adhesion correction accessories, dental defect repair, anti-caries coating dent and pit, etc., has achieved more significant results. Applying a solution of phosphoric acid to the tooth surface is the first step when using a large part of the adhesive material. This process is called Acid etching. A large number of studies have been reported on the tissue structure, changes in physical properties and remineralization after acid treatment of tooth surfaces. December 1974, in Switzerland
