复合树脂嵌体在儿童恒牙应用的临床初步观察

Primary evaluation of the composite resin inlay used in the childrens permanent teeth

目的 探讨复合树脂嵌体技术在儿童恒牙牙体修复中的应用价值。方法 用间接法对 5 6颗大面积缺损的恒磨牙和双尖牙进行复合树脂嵌体修复 ,追踪观察 6个月～ 1年。用改良USPHS标准进行临床评价。结果修复体固位率为 96 .4% ,边缘密合性及色泽协调性较好 ,牙髓状况良好 ,与修复体相关的牙龈指数略有增加。仅 1例发生继发龋。结论 复合树脂嵌体可作为儿童期恒磨牙、双尖牙缺损修复的一种适用方法。

Objective To investigate the value of the composite resin inlay to restore the childrens permanent teeth.Methods 56 seriously destroyed permanent molars and premolars were restored by the composite resin inlays in indirect way.The cases were observed for 6 months to 1 year.The long term results were evaluated by modified USPHS.Results The retaining rate of the composite resin inlays was 96.4% in total.The marginal adaptation and the color match were acceptable.All the pulps were vital.There was a slight increase of the gingival index in the gums which were adjacent to the inlays.Only one case (1/56) had secondary caries.Conclusion The composite resin inlay is a new alternative to the restoration of childrens permanent molars and premolars.
