【摘要】：目的:比较选择性激光融积钴铬合金烤瓷冠和传统铸造钴铬合金烤瓷冠的临床修复效果。方法 :选择168例、220颗患牙,分别用选择性激光融积钴铬合金烤瓷冠和铸造钴铬合金烤瓷冠修复,在粘结后1、6、12、24个月进行随访观察。采用美国公共健康协会的修订标准对修复体的临床效果进行评价,并用SPSS 20软件包对数据进行t检验和χ2检验。结果:观察期间失访6例,随访162例共205件修复体,结果显示,选择性激光融积钴铬合金烤瓷冠患者满意度较好。在粘结24个月后,1个修复体的边缘密合度欠佳;而铸造钴铬合金烤瓷冠组有6例边缘着色,8例边缘密合度欠佳,两组间比较差异具有差异性(P0.05)。结论:选择性激光融积钴铬合金烤瓷冠边缘着色较少,具有良好的边缘密合度,近期临床效果满意。
[Abstract]:Objective: To compare the clinical effect of selective laser melting cobalt chromium alloy porcelain crowns and traditional cast cobalt chromium alloy porcelain crowns. Methods: 168 cases and 220 teeth were selected by selective laser melting cobalt chromium alloy porcelain crown and cast cobalt chromium alloy porcelain crown respectively, and followed up for 1,6,12,24 months after bonding. The revised standard of the Health Association evaluated the clinical effects of the restorations and used the SPSS 20 software package to test the data by t test and x 2 test. Results: 6 cases were lost during the observation period and 205 restorations were followed up in 162 cases. The results showed that the selective laser thawing cobalt chromium alloy porcelain crowns had better satisfaction. 1 restorations after 24 months were bonded. The marginal consistency was poor, and the cast cobalt chromium alloy porcelain crown group had 6 cases of edge coloring, 8 cases with poor marginal consistency, and the difference between the two groups was different (P0.05). Conclusion: selective laser melting cobalt chromium alloy porcelain crown has less edge coloring, with good edge density, and recent clinical effect is satisfactory.
