摘　　要：目的评价金沉积、金合金和镍铬合金3种不同基底烤瓷冠临床应用效果。方法对2004年5月至2006年5月在辽宁省妇幼保健院口腔科进行烤瓷冠修复的患者35例(120颗牙),根据患者要求分别制作镍铬合金基底、金合金基底、金沉积基底烤瓷冠,每种基底烤瓷冠40颗牙。观察比较戴冠2年后3组烤瓷冠在颜色、边缘的密合度、牙龈染色等方面的情况。结果金合金基底、金沉积基底烤瓷冠在颜色、冠边缘的密合度及颈缘染色均优于镍铬合金基底烤瓷冠,差异有统计学意义(P<0.05)。结论金合金基底和金沉积基底烤瓷冠临床效果好。Objective To compare the clinical effect of the ceramic crowns made of Ni-Cr alloy,gold alloy,gold-electroforming.Methods One hundred and twenty ceramic crowns were made of three alloys respectively(40 pieces eacht ype).The color,margin fitness and cervical gray line of the ceramic crowns were checked after 2 years.Results Theg old-electroforming and gold alloy ceramic crowns were better than the Ni-Cr alloy ceramic crowns in color,cervicalg ray line and margin fitness(P<0.05).Conclusion The clinical effect of gold alloy and gold-electroforming ceramicc rowns is better than the Ni-Cr alloy ceramic crowns.
