The loss of anterior teeth may be transient solved by temporary adhesive bridges (Oslo bridge, Rochette, Ellmann, Neumann, Tschemitscheck, Armatron systems). Provisional crowns and bridges could be used for Brackets fixing. Anterior bridge with subocclusal connector permits transversal expansion. When a successful orthodontic treatment is followed by a prosthetic treatment, it is not important to change the achieved occlusion, by the occlusal framework morphology. The framework design of the metal component can contribute to the improvement of the aesthetic aspect and reduce the cost by using a small quantity of expensive alloy. Cytocompatibility of the used Cr-Co alloy is confirmed by cell culture test.
前牙缺失可通过临时粘结桥（奥斯陆桥、罗谢特、埃尔曼、诺伊曼、切米奇茨克、阿玛特隆系统）暂时解决。临时冠和桥可用于托槽固定。带有咬合下连接体的前桥允许横向扩展。当成功的正畸治疗之后进行修复治疗时，通过咬合架形态改变已获得的咬合关系并不重要。金属部件的支架设计可通过使用少量昂贵合金来改善美观并降低成本。所用铬钴合金的细胞相容性通过细胞培养试验得以证实。
