目的：观察桩核冠修复后牙不同缺损程度残冠的疗效。方法：根据牙冠缺损程度（残存洞壁数）将后牙残冠分为4类，随访观察226个后牙残冠桩核冠修复的疗效。结果：226个后牙残冠治疗后，随访观察3～7年，随访到201个，其中成功190个（成功率94．5％），失败11个；在4类缺损后牙残冠中，缺损3洞壁的Ⅲ类残冠成功率（83．9％）明显低于缺损1、2和4洞壁的Ⅰ、Ⅱ、Ⅳ类残冠；在Ⅲ类残冠中树脂桩核和纤维桩核修复的疗效略好于金属铸造桩核，前磨牙桩核冠修复的疗效略好于磨牙，但均无统计学差异（P＞0．05）。结论：后牙残冠的桩核冠修复疗效与其缺损洞壁数目有关，残存1洞壁并丧失完整肩领结构的Ⅲ类残冠修复效果最差。
目的：觀察樁覈冠脩複後牙不同缺損程度殘冠的療效。方法：根據牙冠缺損程度（殘存洞壁數）將後牙殘冠分為4類，隨訪觀察226箇後牙殘冠樁覈冠脩複的療效。結果：226箇後牙殘冠治療後，隨訪觀察3～7年，隨訪到201箇，其中成功190箇（成功率94．5％），失敗11箇；在4類缺損後牙殘冠中，缺損3洞壁的Ⅲ類殘冠成功率（83．9％）明顯低于缺損1、2和4洞壁的Ⅰ、Ⅱ、Ⅳ類殘冠；在Ⅲ類殘冠中樹脂樁覈和纖維樁覈脩複的療效略好于金屬鑄造樁覈，前磨牙樁覈冠脩複的療效略好于磨牙，但均無統計學差異（P＞0．05）。結論：後牙殘冠的樁覈冠脩複療效與其缺損洞壁數目有關，殘存1洞壁併喪失完整肩領結構的Ⅲ類殘冠脩複效果最差。

AIM:To observe the effect of post-and-core crown in the treatment of molar residual crowns with different degree of defects.METHODS:226 residual crowns were devided into 4 types according to the defect degree of residual crowns.The crowns were restored with post-and-core crowns and 201 crowns were followed-up for 3~7 years.RESULTS:190 of the 201 teeth(94.5%)were successfully restored.The treatment success rate of re-sidual crown type Ⅲ(defects of 3 walls)was lower(83.9%)than that of other types.CONCLUSION:The effect of post-and-core crown in the treatment of residual crowns is related to the number of defected walls.The lowest success rate is produced in the treatment of Type Ⅲ residual crown.
