摘　　要：目的观察和评价金属烤瓷冠桥修复临床效果。方法对986颗牙分别采用镍铬合金与金合金行金属烤瓷冠桥修复,修复后2年复查比较两种方法的优缺点。结果复查的516例病例中,镍铬合金组并发症为23.11%,而金合金组仅为8.04%,两者差异有显著统计学意义(χ2=12.53,P<0.01)。结论金属烤瓷冠桥修复中金合金的疗效高于镍铬合金,值得临床推广。Objective To evaluate the clinical effect of the restoration of metal porcelain crowns/bridges Methods 986 teeth were received metal porcelain crowns/bridges restoration by Ni - Cr alloy and Gold alloy respectively. Followed up two years and then compare to the clinical effect of these two types of restoration. Results In 516 follow up cases, 23.11% teeth restored by Ni -Cr alloy porcelain crowns/bridges had complications, while only 8.04% restored by Gold alloy had complications, there was a statistic significance（ χ^2 = 12.53 ,P 〈0.01 ）. Conclusion The Gold ally has better clinical effect compare to Ni - Cr alloy in metal porcelain crowns/bridges, thus should be recommended clinically.
