铸瓷贴面在前牙美容修复中的临床效果观察

Observation on the effect of ceramic faced in the repair of anterior teeth beauty

目的 研究铸瓷贴面在前牙美容修复中的临床效果。方法 将34例（138牙）氟斑牙患者随机分为两组,对照组16例（69牙）采用传统烤瓷贴面修复,治疗组18例（69牙）采用铸瓷贴面技术进行修复,随访3年,记录并比较两组患者的牙齿存留率及患者满意度,并采用改良Ryge标准对两组患者牙齿的颜色匹配、边缘密合度、牙龈健康、修复体完整度等指标进行评价。结果 3年后治疗组患者牙齿存留率为95.7%,明显高于对照组的89.9%,差异有统计学意义（P〈0.05）;治疗组患者满意度为94.4%,对照组为87.5%,差异有统计学意义（P〈0.05）;两组颜色匹配、边缘着色、牙龈健康以及牙齿敏感度差异无统计学意义（P〉0.05）,但治疗组患者修复体完整度以及边缘密合度明显好于对照组,差异有统计学意义（P〈0.05）。结论 铸瓷贴面在前牙美容修复,特别是氟斑牙的修复中临床效果显著,牙齿存留率更高,修复牙修复体完整度及边缘密合度明显好于树脂修复,患者满意度更高。

Objective To study the clinical effect of ceramic cover anterior on teeth beauty.Methods 138 teeth in 34 patients with dental fluorosis were divided into two groups,the control group （69 teeth in 16 patients） was given traditional PFM cover repair,the treatment group （69 teeth in 18 patients） was given ceramic cover,they were followed up for three years.The teeth remaining rate and patient satisfaction were compared,the match color,edge fit,healthy gums,restoration integrity were compared according to the Ryge standard.Results Teeth remaining rate in treatment group was 95.7%,which was significantly higher than control group （P〈0.05）.The patient satisfaction was 94.4% in treatment group and 87.5% in the control group,the difference was significant （P〈0.05）.The match color,edge coloring,healthy gums and teeth sensitivity were not different between the two groups （P〉0.05）.The restoration integrity and marginal fit of treatment group was better than control group （P〈0.05）.Conclusion The clinical effect of ceramic faced in the anterior teeth beauty repair,especially in the repair of dental fluorosis is remarkable,and the remaining teeth rate higher,repair,dental restoration integrity and marginal fit is significantly better than that of resin repair,patient satisfaction is higher,the water area from non-beryl popularization and application.
