摘要
目的:探讨CEREC 3全瓷冠修复早期牙隐裂保存活髓的临床效果。方法:选择138颗早期隐裂患牙分为三组,直接树脂修复组(A组)、顿号普通金属烤瓷全冠修复组(B组)、CEREC 3全瓷冠修复组(C组),观察并评价半年、1年、2年的临床疗效。结果:CEREC 3全瓷冠修复组及普通金属烤瓷全冠修复组较树脂修复组具有优势,能明显降低牙隐裂所致的后续并发症,一年成功率及两年成功率差异有统计学意义(P<0.05);CEREC全瓷冠修复组与普通金属烤瓷全冠修复组在两年成功率上比较差异有统计学意义(P<0.05)。结论:CEREC 3全冠修复对早期牙隐裂的治疗有效可靠,能够有效降低牙折及治疗后牙髓炎等的发生率,并有较好的修复效果。
Objective： To discuss the clinical effect of preserve vital pulp of cracked tooth through CEREC3 all-ceramic crowns.Method： 138 crack teeth in early stage were divided into three group： direct resin restoration group （A group）, PFM （Porcelain-fused-to-metal crown） group （B group） and CEREC 3 all- ceramic cro^aa group（C group）. Observation and evaluation were performed separately after 0.5 year, 1 year and 2 years.Result： The pulp survival rate for B group and group were much better than A group, the significant difference were found in three groups（P〈O.05）.There was statistical difference on 2-year evaluation of B group and C group（P〈O.05）.Conclusion： The most effective approachment to restore cracked tooth is though CEREC 3 all-ceramic crown with low pulpitis rate and excellent aesthetic performance.
