金属烤瓷冠修复5年临床观察

Clinical Observation on the Metal Porcelain-Complete-Veneer-Crown Repair for Five Years

目的：探索固定义齿修复后基牙的发病规律，提高烤瓷修复后远期疗效。方法：随访观察356例行固定义齿修复的患者，修复5年来基牙和牙周的发病情况，分析患者年龄、修复体材料、修复时间与基牙发病和牙周病的关系。结果：50岁以上年龄组患者修复后基牙发病明显高于49岁以下年龄组。基牙发病与修复材料无关；修复后第1年基牙发病明显高于其后4年。结论：基牙发病与患者年龄及修复体戴用的时间有关，与修复体材料无关。牙周病与修复材料及修复时间有关。

Objective： Exploring the orderliness of the disease coming on after repairing the fixed false tooth, and improving the long-term curative effect of Ceramic repair; Method： Observing the condition of the disease coming on of 356 patients repairing the fixed false tooth, analyzing the patients＇ age, repair materials, repair time and the relation between base tooth disease coming on and parodontopathy for five years; Results： The incidence of a disease of the group of 50 and over is higher than the group under 49, the disease coming on of base tooth is independent of repair material, and the incidence of a disease of base tooth in the first year is higher than the following four years; Conclusion： They are correlative of the disease coming on of base tooth and patients＇ age and the time using repair instrument, and it＇s independent of repair material. And they are correlative of the parodontopathy and repair material and repair time.
