摘　　要：目的:比较镍铬合金基底、钛合金基底、金合金基底烤瓷冠的临床应用效果。方法:分别制作镍铬合金基底、钛合金基底、金合金基底基底烤瓷冠,每种基底烤瓷冠各选取20例,观察三者戴入时及戴入2年后烤瓷冠的颜色、冠边缘的密合度、颈缘染色及冠的折裂、折断情况。结果:金合金基底烤瓷冠的颜色、冠边缘的密合度及颈缘染色均优于钛合金、镍铬合金基底烤瓷冠(P<0.01),三者在冠的折裂、折断方面的差异无显著性(P>0.05)。结论:钛合金烤瓷冠作为一种价格适中的底冠,能基本满足临床要求。Objective ：To evaluate the clinical effect of Ni-cr alloy ,high-gold alloy and Ti alloy porcelain crowns.Methods：The Ni- Cr alloy,high-gold alloy and Ti alloy porcelain crowns were made respectively. Every kind of PFM was 20 pieces. The evaluator examined the prosthesis for shade,gingival color ,marginal fit and porcelain defect. Results：The results showed that the Ti alloy porcelain was similar to Ni--Cr alloy ceramic crowns in shade ,gingival color and fitness. The effect of them was better in high - gold alloy than that in Ni-Cr alloy and Ti alloy （P〈0.01）. The fracture of 90 porcelain crowns was not found out in two years （P〉0.05）. Conclusion： The Ti alloy porcelain restoration can be used for the clinical application as its cheap price.
