目的:比较全瓷冠与金属烤瓷冠在牙齿修复中的临床效果。方法 ;选择2013年2月至2014年2月收治的冠桥修复患者65例,共100颗患牙,全部进行烤瓷冠修复,按修复方法分为烤瓷冠组(观察组)和全瓷冠组(实验组)各50颗,1年后随访患者,观察修复后的外形、色泽,以及牙龈变化,并进行比较分析。结果:修复1年后,两种冠修复体的外形和色泽无明显改变。烤瓷冠修复后,61.4%的患牙牙龈发生变色,32.5%患牙出现轻度牙龈炎,全瓷冠修复后无一例发生牙龈变色及牙龈炎。实验组牙齿修复总有效率(94.17%)明显高于观察组(77.14%).结论:全瓷牙与金属烤瓷牙都具有较好的牙齿修复效果,金属烤瓷牙不易折断,全瓷牙具有对牙周组织损伤小的优点,且效果逼真且美观。因此,临床实践中应综合根据患者意愿选择义齿类型,以达到更好的修复效果。
Objective: To compare the clinical effect of all-ceramic crowns and metal porcelain crowns in dental restoration. Methods Totally 65 patients with crown bridge repair who were treated from February 2013 to February 2014 were enrolled. All the 100 teeth were repaired with porcelain crowns. All the porcelain crowns (observation group) and all porcelain Fifty patients in the crown group (experimental group) were followed up one year later. The shape, color and gingival changes were observed and compared. Results: After 1 year of repair, there was no significant change in the shape and color of the two kinds of coronal prosthesis. After the restoration of porcelain crowns, discoloration of the gums occurred in 61.4% of the affected teeth, mild gingivitis occurred in 32.5% of the affected teeth, and no gingival discoloration and gingivitis occurred after the restoration of the porcelain crowns. The total effective rate of dental restoration in the experimental group (94.17%) was significantly higher than that of the observation group (77.14%) .Conclusion: All ceramic teeth and metal porcelain teeth have better dental restoration effect, metal porcelain teeth are not easy to break, Has the advantages of small periodontal tissue damage, and the effect realistic and beautiful. Therefore, clinical practice should be based on the patient’s wishes to choose the type of denture, in order to achieve a better repair effect.
