摘要
目的:评价镍铬合金、高金合金及金沉积基底烤瓷冠的颈缘密合度。方法:分别制作镍铬合金、高金合金及金沉积基底烤瓷冠各100件。修复完成时和完成后18个月临床检查烤瓷冠的颈缘密合度。结果:金沉积及高金合金基底烤瓷冠的颈缘密合度明显优于镍铬合金(P<0.05)。结论:金沉积及高金合金基底烤瓷冠有良好的颈缘密合度,具有临床推广价值。
Objective： To evaluate the marginal adaptation of Ni-Cr alloy, high-gold alloy and auro-galvano-form ceramic crowns. Methods：The Ni-Cr alloy, high-gold alloy and auro-galvano-form ceramic crowns were made respectively. Every kind was 100 pieces. The marginal adaptation of these crowns was observed. Results ： The marginal adaptation of high-gold alloy and auro-galvano-form ceramic crowns were better than Ni-Cr alloy （ P 〈 0. 05 ）. Conclusion： The marginal adaptation of high-gold alloy and auro-galvano-form ceramic crowns were perfect. They can be used in clinic.
