目的：对比三种全冠修复的边缘适合性效果进行对比，以指导临床的治疗。方法根据临床完成的镍铬合金烤瓷冠、贵金属烤瓷冠和全瓷冠修复，1年后复诊观察所有全冠的边缘适合性。结果镍铬合金烤瓷牙边缘适合性A级的占86.5％，贵金属烤瓷牙边缘适合性A级的占95.1％，全瓷牙边缘适合性 A级的占96.6％。结论对于镍铬合金烤瓷冠边缘的密合性差，而全瓷冠与贵金属烤瓷冠具有很好的边缘适合性。

Objective To repairing ef ects on marginal adaptation of Ni-Cr al oy porcelain crowns,al-ceramic crowns and metal ceramic crowns compared to guide clinical treatment. Methods According to the teeth conditions and needs of patients,use Ni-Cr al oy porcelain teeth,dental precious metal ceramic and al -ceramic dental restoration to repair,one year after referral to observe al the objects in gingival color,gingival index and marginal fit. Results Ni-Cr al oy porcelain teeth marginal fit of Class A accounted for 86.5%.accounting for 95.1%of Class A of the marginal fit of precious metal porcelain tooth edge.al -cerainlc dental marginal fit of Class A accounted for 96.6%. Conclusion For the Ni-Cr al oy porcelain teeth,crowns fit is poor and the binder dissolution caused by the local pigment deposi-tion is the main reason to cause periodontal damage caused by gum color change.Al-ceramic dental and precious metal ceramic teeth has go d biocompatibility and marginal adaptation of virtual y no efect on the color of the gums and gingival index.
