目的探讨牙列缺损患者应用金属烤瓷冠固定修复的临床疗效,并比较其对前牙和后牙的治疗效果。方法将2008年6月-2011年6月我科收治的164例应用金属烤瓷冠固定修复牙列缺损的患者随机分成前牙组90例和后牙组74例,随访1年,观察比较两组的成功率和并发症发生率。结果前牙组患者治疗后成功86例、成功率为95.6%,后牙组患者治疗后成功65例、成功率为92.9%,两组比较差异无统计学意义(P>0.05);前牙组发生崩瓷2例、继发牙龈炎1例、冠桩脱落1例、并发症发生率为4.4%,后牙组发生崩瓷3例、继发牙龈炎1例、冠桩脱落1例、并发症发生率为7.1%,两组比较差异无统计学意义(P>0.05)。结论牙列缺损应用金属烤瓷冠固定修复临床治疗成功率高、安全有效、并发症少,并且对于前牙、后牙具有同样的修复效果,是一种极具应用前景的修复治疗方法。
Objective To investigate the clinical effect of fixed metal-ceramic crowns in patients with dentition defect and to compare the therapeutic effect of anterior teeth and posterior teeth. Methods From June 2008 to June 2011, 164 cases of patients with dentition defect repaired with metal porcelain crowns were randomly divided into anterior teeth group (n = 90) and posterior teeth group (n = 74), followed up for 1 year. Group success rate and complication rate. Results In the anterior teeth group, 86 cases were successfully treated with a success rate of 95.6% and 65 cases were successfully treated with posterior teeth group with a success rate of 92.9%. There was no significant difference between the two groups (P> 0.05) 2 cases of collapsed porcelain, 1 case of secondary gingivitis, 1 case of crown peeling, the incidence of complications was 4.4%, 3 cases of posterior teeth group collapse, 1 case of secondary gingivitis, 1 case of crown off, The incidence of disease was 7.1%, there was no significant difference between the two groups (P> 0.05). Conclusion The application of metal porcelain crowns in the restoration of dentition defect has high success rate, safe and effective, few complications, and the same repairing effect on the anterior teeth and posterior teeth. It is a promising method of repair and treatment.
