将电解蚀刻技术应用于粘结固定桥,使金属的粘结界面形成凹凸不平的峰谷凹陷,使之与粘合树脂的粘结力增加,超过树脂同酸蚀釉质面之间的粘接力,固定板的厚度也相应减小。这种粘接固定桥称为蚀刻固定板粘结桥,又叫马利兰固定桥。Ibsen 和Neville 认为粘结固定桥是近30年来固定桥最突出、最重要的发展。 Electrolytic etching technology is applied to the bonded fixed bridge, the metal bonding interface to form a rugged peak valley depression, so that the bond with the adhesive resin increases, exceeding the resin with acid enamel surface adhesion , The thickness of the fixed plate is also reduced accordingly. This bonding fixed bridge is called the etching fixed plate bonding bridge, also known as Maryland fixed bridge. Ibsen and Neville believe that the bonded fixed bridge is the most prominent and important development of the fixed bridge in the past 30 years.
