| 摘 要： | [摘要] 目的 比较含钛镍铬合金、钴铬合金、高金合金烤瓷修复体的临床应用效果。方法 选择含钛镍铬合金、钴铬合金和高金合金烤瓷修复患者分别为189例(233单位冠)、206例(251单位冠)和97例(118单位冠)修复完成后分别于3个月、1年、3年复查,检查烤瓷冠的色泽、牙龈炎症、龈缘变色以及裂纹或折裂或崩瓷情况。结果含钛镍铬合金、钴铬合金烤瓷冠在色泽、龈缘炎症(3个月时)、裂纹或折裂或崩瓷方面无显著性差异(P>0.05);龈缘变色(1年及3年时)含钛镍铬合金烤瓷冠高于钴铬合金,并明显高于高金合金烤瓷组(P<0.05);裂纹或折裂或崩瓷,3种材料烤瓷牙相比较,差别无显著性(P>0.05)。结论 高金合金烤瓷冠在化学稳定性、生物相容性、色泽方面具有明显优势;钴铬合金近几年来已逐步取代镍铬合金烤瓷冠;镍铬合金烤瓷冠远期效果有待进一步考证。
