A total of 203 resin-bonded bridges was inserted under controlled clinical conditions and evaluated for a number of patient-dependent variables over a period of 5 years. Of the variables evaluated only 'initial occlusion of the abutment teeth' and 'location in the dental arch' had a significant influence on the retention of resin-bonded bridges. Anterior resin-bonded bridges were more durable than posterior bridges. Mandibular posterior bridges showed the lowest retention ratio. It is concluded that the design of posterior resin-bonded bridges should include tooth preparation or a wrap-around design of the retainers.
在可控的临床条件下共植入了203颗树脂粘结桥，并在5年的时间里对一些与患者相关的变量进行了评估。在所评估的变量中，只有“基牙的初始咬合”和“牙弓中的位置”对树脂粘结桥的固位有显著影响。前牙树脂粘结桥比后牙桥更耐用。下颌后牙桥的固位率最低。结论是，后牙树脂粘结桥的设计应包括牙体预备或固位体的环抱式设计。
