The survival rate of 1674 bridges and the influence of several factors on the lifetime of bridges were analysed, based on data from patient records that belonged to a random sample of 40 Dutch general practices. It appears that the 12 year survival rate of the bridges is 87%. There is a significant difference in the survival rate between the bridges that meet and do not meet Ante's law, and only a weak significant difference between the bridges with vital vs. non-vital abutment teeth. Gender and age of the patient, length of the bridge, presence of a post and core build-up, or the construction of the bridge (conventional fixed vs. cantilever pontic) appear to have no influence on the survival rate of the bridges in this sample.
基于来自荷兰40家普通诊所随机样本的患者记录数据，分析了1674颗牙桥的存活率以及几个因素对牙桥寿命的影响。结果显示，牙桥的12年存活率为87%。符合和不符合安特法则的牙桥存活率存在显著差异，而基牙为活髓与死髓的牙桥之间只有微弱的显著差异。患者的性别和年龄、牙桥长度、是否存在桩核修复或牙桥的构造（传统固定桥与悬臂桥）在该样本中似乎对牙桥的存活率没有影响。
