The extraction rate was studied in a group of 151 patients treated for periodontal and prosthodontic reasons. 29 of 588 abutments had to be extracted due to periodontal problems within a period of 6 years after prosthodontic treatment. The initial findings of the extracted teeth are correlated with the initial findings of all abutments. It can be shown that periodontally reduced teeth involve a higher risk of extraction; nevertheless, in the majority of the cases, they could be successfully used as abutments.
在一组因牙周和修复原因接受治疗的151例患者中研究了牙体拔除率。在修复治疗后的6年内，588个基牙中有29个因牙周问题而不得不拔除。拔除牙齿的初始检查结果与所有基牙的初始检查结果相关。结果显示，牙周状况不佳的牙齿拔除风险更高；然而，在大多数情况下，它们仍可成功用作基牙。
