目的比较金属烤瓷冠和全瓷冠对牙齿修复的临床效果。方法选取2011年4月—2012年4月我院收治的80例冠桥修复患者,依据患者意愿,将其分为对照组(22例)和试验组(58例),对照组采用镍铬合金烤瓷冠,无酸水门汀粘结;试验组采用全瓷冠,利用计算机技术制作完成后用双重固化树脂粘结。记录所有患者治疗效果,并对其随访1年,观察修复有效性和并发症情况。结果试验组患者牙龈健康和美观度高的比例高于对照组,牙齿折裂比例低于对照组(P<0.05)。试验组总有效率为94.8%,高于对照组的77.0%(P<0.05)。结论全瓷冠对牙周组织损伤较小,但是会有一定的裂纹出现,总体上是一种较好的修复牙齿的方法。
Objective To compare the clinical effect of metal porcelain crowns and all-ceramic crowns on dental restoration. Methods Eighty patients with crown-bridge repair who were treated in our hospital from April 2011 to April 2012 were divided into control group (n = 22) and experimental group (n = 58) according to patients’ wishes. The control group was treated with nickel-chromium alloy Porcelain crown, acid-free cement bonding; test group using all-ceramic crown, the use of computer technology after the completion of double-cured resin bonding. All patients were recorded for treatment and follow-up for 1 year to observe the effectiveness of the repair and complications. Results The proportion of gum health and aesthetics in the test group was higher than that in the control group, and the rate of tooth fracture was lower than that of the control group (P <0.05). The total effective rate of the experimental group was 94.8%, which was higher than that of the control group (77.0%, P <0.05). Conclusion All-ceramic crowns have less damage to the periodontal tissue, but there will be some cracks, which is a better method of repairing the teeth.
