透明预成冠在乳前牙外伤修复中的疗效分析

Clinical analysis of transparent preformed crown in the restoration of traumatic primary anterior teeth

目的分析研究采用复合树脂直接修复和透明预成冠修复外伤折裂乳前牙的疗效。方法随机选取该院口腔科就诊的21例23颗折裂乳前牙作为试验组,进行透明预成冠修复;18例22颗折裂乳前牙纳入对照组,进行复合树脂直接修复,比较两组治疗后6、12、24个月的疗效。结果治疗后6个月试验组(100%)修复成功率高于对照组(95.45%),12个月后试验组(95.65%)修复成功率高于对照组(81.82%),但差异均无统计学意义(P>0.05);24个月后试验组(91.30%)修复成功率高于对照组(59.09%),差异有统计学意义(P<0.05)。结论透明预成冠修复折裂乳前牙可提高修复成功率,最大程度保存患牙,并有效减少并发症。

Objective To analyze the effects of the composite resin direct restoration and transparent preformed crown in the treatment of traumatic primary anterior teeth.Methods A total of 23 cracked anterior teeth from 21 patients in the Department of Stomatology of this hospital were randomly selected as the experimental group,which were restored with the transparent performed crown.A total of 22 cracked anterior teeth from 18 patients were included in the control group,which were directly restored with composite resin.Then the therapeutic effects were compared in the two groups after 6,12,24 months of treatment.Results After 6 months,the success rate of the experimental group(100%)was higher than that of the control group(95.45%).After 12 months,the success rate of the experimental group(95.65%)was higher than that of the control group(81.82%),but the differences were not statistically significant(P>0.05).After 24 months,the success rate of the experimental group(91.30%)was significantly higher than that of the control group(59.09%),the difference was significantly different(P<0.05).Conclusion The transparent preformed crown can improve the success rate of the repairing cracked primary anterior teeth,preserve the teeth to the greatest extent,and effectively reduce the complications.
