摘要： 摘要：目的 评价镍铬合金、镀金镍铬合金、钛合金、金钯合金4种金属烤瓷冠的临床应用效果。方法 对2003年4月至2006年9月大连大学附属中山医院口腔科门诊需要行金属烤瓷冠修复的320例患者的上前牙320颗，根据患者的要求分别制作铸造镍铬合金、镀金镍铬合金、钛合金、金钯合金烤瓷冠各80颗，并进行3年的临床追踪观察。对各组烤瓷冠进行边缘适合度、颜色及牙龈染色情况评价。结果 金钯合金烤瓷冠边缘密合度好，优于镍铬合金、镀金镍铬合金和钛合金（P < 0.05）;金钯合金烤瓷冠颜色效果好，与镍铬合金冠及钛合金烤瓷冠比较，差异有统计学意义（P < 0.05）;牙龈染色现象在钛合金烤瓷冠组发生率最高，金钯合金烤瓷冠组发生率最低（P < 0.05）。结论 金钯合金烤瓷冠具有良好的边缘适合性和生物相容性，制作出的烤瓷冠表现出较好的美学效果，几乎不会出现颈缘黑线，是目前金属烤瓷修复中比较理想的修复材料。

Abstract: Abstract：Objective To compare the clinical effect of the Ni-Cr alloy，Gold-plating Ni-Cr alloy，Titanium alloy and Au-Pd alloy coping of the porcelain-fused-to-metal （PFM）. Methods According to the request of 320 patients who needed to have the PFM repairment，manufacture the metal coping of Ni-Cr alloy，Gold-plating Ni-Cr alloy，Titanium alloy and Au-Pd alloy respectively，with 80 for each，and 3-year clinical tracing observation was made. Results Au-Pd alloy had highter edge adhesion than the Ni-Cr alloy，Gold-plating Ni-Cr alloy and the Titanium alloy（P < 0.05）. The color effect of Au-Pd based dental alloy proves to be good（P < 0.05），when compared with the other alloy groups. The incidence of the marginal gingival coloration and gingivitis was the highest in Titanium alloy，and Au-Pd alloy was the lowest when compared with other 3 groups（P < 0.05）. Conclusion The Au-Pd based dental alloy has good edge suitability and biological compatibility，and the gold-plating Ni-Cr alloy and the Ni-Cr alloy have stable biology property. Titanium alloy stability and the color change need further studies.
