目的：评价全牙列牙合垫用于儿童外伤前牙固定的临床效果。方法：选择58例7～12岁儿童，其中男42例，女16例，随机分为两组，实验组（30例）采用全牙列颌垫固定，对照组（28例）采用弓丝托槽技术固定。比较治疗前及固定4周后的牙松动度、患者舒适指数、牙龈指数和医生临床操作时间，并进行统计学分析。结果：外伤牙固定4周后，疗效差异无统计学意义（P＞0．05）；患者舒适指数、牙龈指数、临床操作时间全牙列牙合垫优于弓丝托槽（P＜0．05）。结论：全牙列牙合垫用于混合牙列期儿童外伤前牙固定效果可靠，且较舒适，对牙周刺激小，可节省时间。

AIM:To evaluate the clinical effects of vacuum-formed jaw-pillow used for teeth fixing in chil-dren with traumatic anterior teeth.METHODS:58 cases of children (42 males and 16 females aged 7 -12 years) with anterior teeth trauma were randomly divided into 2 groups,and respectively treated by vacuum-formed jaw-pillow (30 cases)and arc wire (28 cases).The clinical operation time,tooth mobility,patient comfort index and gingival index were compared between the 2 groups before and 4 weeks after treatment .Tata were statistically analyzed.RE-SULTS:The efficacy between the 2 groups was not statistically different (P>0.05);the comfort index,gingival in-dex and clinical operation time of vacuum-formed jaw-pillow group were obviously better than those of control group (P<0.05).CONCLUSION:Vacuum-formed jaw-pillow used for teeth fixing in children with traumatic anterior is superior to arc wire .
