Abstract
On the basis of 1718 teeth in 212 patients fitted with removable partial dentures, it was established that the frequency of caries in uncontrolled noncrowned abutment teeth for partial dentures was twice as high and the number of extractions three times as high as in the control group. The special risk for abutment teeth was effectively reduced by using artificial crowns. The concept of crowning abutment teeth is discussed.
摘要
基于212例佩戴可摘局部义齿患者的1718颗牙齿，研究发现，局部义齿未做冠修复的基牙龋病发生率是对照组的两倍，拔牙数量是对照组的三倍。使用人工牙冠可有效降低基牙的特殊风险。文中还讨论了基牙冠修复的概念。
