全瓷冠与金属烤瓷冠在牙齿修复中的效果及安全性比较

Comparison of effects and safety of all-ceramic crowns and porcelain-fused-to-metal crowns in restoration of teeth

目的比较全瓷冠与金属烤瓷冠在牙齿修复中的效果及安全性。方法回顾性分析我院2018年1月至2020年1月收治的120例接受冠桥修复患者的临床资料,患牙均位于前牙区,按照烤瓷冠修复材料不同将其分为全瓷冠组(n=62)及金属烤瓷冠组(n=58)。比较两组的临床疗效、牙周临床指标、牙龈指数分级情况、患者对牙齿修复效果的满意度及随访6个月、1年的并发症发生情况。结果全瓷冠组的治疗总有效率显著高于金属烤瓷冠组(P<0.05)。治疗6个月后,两组的PLI、BI、PD均高于治疗前(P<0.05);但组间比较,差异无统计学意义(P>0.05)。全瓷冠组的牙龈指数0级患者占比显著高于金属烤瓷冠组(P<0.05)。全瓷冠组患者对牙齿修复效果的满意度显著高于金属烤瓷冠组(P<0.05)。全瓷冠组随访6个月、1年的并发症总发生率均显著低于金属烤瓷冠组(P<0.05)。结论与金属烤瓷冠修复牙齿相比,全瓷冠的临床疗效更高,且患者对此修复效果的满意度也较高,短期随访期间未见明显的并发症,安全性较高,预后较好。

Objective To compare the effects and safety of all-ceramic crowns and porcelain-fused-to-metal crowns in restoration of teeth.Methods The clinical data of 120 patients who underwent crown and bridge restoration admitted in our hospital from January 2018 to January 2020 were analyzed retrospectively.The affected teeth were located in the anterior tooth area.According to the different restoration materials of ceramic crowns,the patients were divided into all-ceramic crowns group(n=62)and porcelain-fused-to-metal crowns group(n=58).The clinical efficacy,periodontal clinical indexes,gingival index grading,patients'satisfaction with the effect of dental restoration,and the occurrence of complications after follow-up of 6 months and 1 year were compared between the two groups.Results The total effective rate of treatment of the all-ceramic crowns group was significantly higher than that of the porcelain-fused-to-metal crowns group(P<0.05).After 6 months of treatment,PLI,BI and PD of the two groups were higher than those before treatment(P<0.05);however,there were no significant differences between the two groups(P>0.05).The proportion of patients with gingival index grade 0 in the all-ceramic crowns group was significantly higher than that in the porcelain-fused-to-metal crowns group(P<0.05).The patients'satisfaction with the effect of dental restoration of the all-ceramic crowns group was significantly higher than that of the porcelain-fused-to-metal crowns group(P<0.05).After 6 months and 1 year follow-up,the total incidence of complications in the all-ceramic crowns group was lower than that in the porcelain-fused-to-metal crowns group(P<0.05).Conclusion Compared with porcelain-fused-to-metal crowns,all-ceramic crowns can obtain higher clinical efficacy,and patients are also more satisfied with the restoration effect.There are no obvious complications during short-term follow-up,with higher safety and better prognosis.
