目的：追踪观察纤维桩CAD/CAM氧化锆烤瓷冠与传统的钴铬合金铸造桩钴铬合金烤瓷冠的临床效果,为评价纤维桩CAD/CAM氧化锆烤瓷冠的远期临床效果提供参考。方法：同期制作纤维桩CAD/CAM氧化锆烤瓷冠(A组),钴铬合金铸造桩钴铬合金烤瓷冠各21件(B组)。临床检查42件修复体边缘密合性,随访复查修复体的基牙继发龋和修复体的折裂、折断、脱落情况。结果：42件修复体平均随访3年。A组、B组边缘密合性分别为100%和88%(P<0.01)。继发龋的情况也是A组(7.1%)、好于B组(16.7%)(P<0.05)。3年内,核桩脱落数量A组为4例(9.5%),B组为3例(7.1%),崩瓷A组为1例(2.4%),B组为2例(4.8%)。脱落率和崩瓷率无统计学意义(P>0.05)。结论：纤维桩CAD/CAM氧化锆烤瓷冠边缘密合性好,能够达到传统金属固定桥的强度,满足临床应用要求。

Objective:Tracking observation of zirconia fiber pile CAD/CAM of PFM crown with traditional cobalt chromium alloy casting co-cr alloy porcelain crowns, clinical effect. Methods:At the same time production of zirconia fiber pile CAD/CAM porcelain crowns (group A), cobalt chromium alloy casting co-cr alloy porcelain crowns the 21 pieces (group B). And sex, clinical examination restoration margins follow-up review. Results: In group A and group B edge and sex were 100% and 88% respectively (P<0.01). Secondary caries is group A was better than group B (P<0.05). Three years, nuclear pile off quantity for 4 cases of group A, group B for 3 cases, collapsed for 1 case of group A, group B for 2 cases. Loss rate and collapse rate of porcelain has no statistical significance (P>0.05). Conclusion:CAD/CAM zirconia fiber pile PFM crown edge and sex good, can achieve the strength of the traditional metal fixed bridge, satisfies the requirement of clinical application.
