一、前言1973年,Rochette曾用MMA系树脂进行松动牙的暂时固定。以后,一些学者用Bis—GMA系混合树脂固定松动牙,并尝试在前牙缺失时,将塑料牙直接粘接于邻牙上。由于不牢固,又利用金属背板以加强固位,并称之为粘接桥(adhesion bridge)。经过近十年的反复尝试和研究,尤其是随着高分子粘接剂的发展,已使这种方法具有临床使用价值,并由前牙缺失的修复发展到后牙缺失的修复。二、粘接桥的应用优点:1、不切削或少切削基牙牙体组织。2、避免修复体对牙龈的刺激,预防牙
I. Introduction In 1973, Rochette used MMA resin for transient fixation of loose teeth. Later, some scholars used Bis-GMA mixed resin to fix the loose teeth and tried to adhere the plastic teeth to the adjacent teeth directly when the anterior teeth were missing. Due to the weakness, metal backsheets are used to reinforce the retention and are called adhesion bridges. After nearly ten years of repeated attempts and studies, especially with the development of polymer adhesives, this method has been made of clinical value, and the development of anterior teeth missing repair to the repair of posterior teeth missing. Second, the application of bonding bridge Advantages: 1, no cutting or cutting teeth incisor tissue. 2, to avoid prosthetic stimulation of the gums, prevent teeth
