摘　　要：目的研究一种外置型空间稳定装置对植骨区域的成骨影响。方法选取上颌前牙缺失伴牙槽嵴唇侧骨缺损的患者,随机分为两组。试验组在植骨术后戴入外置型空间稳定装置,对照组无佩戴。通过测量分析术前、术后即刻及术后6个月时的CBCT数据,对比在采用或不采用外置型空间稳定装置的情况下,在植骨术后6个月的成骨情况。结果最终入选并观测17个植骨位点,其中试验组7个位点,对照组10个位点。试验组在嵴顶下2 mm和4 mm处的水平骨吸收率显著低于对照组相应观测水平处的水平骨吸收率(P=0.001)。各组牙槽嵴顶下2 mm处的水平骨吸收率均显著高于相应组别中嵴顶下4 mm处的骨吸收率(P=0.003)。结论本研究所使用的外置型空间稳定装置对于维持空间稳定、减少骨吸收具有较好的临床效果。Objective To study the effect of a space stabilizing device on the capacity for osteogenesis in the bone⁃grafted area.Methods Patients with anterior teeth defects as well as labial alveolar ridge defects were randomly divided into two groups:the experi⁃mental group was treated using a space stabilization device after guided bone regeneration whereas the control group received regular guided bone regeneration.The CBCT data was analyzed prior to,immediately and 6 months after procedure to compare the osteogenesis with or without the device.Results Seventeen bone⁃grafted sites were examined(7 in the experimental group and 10 in the control group).At 2 mm and 4 mm below the alveolar ridge,the horizontal bone resorption rate in the experimental group was significantly low⁃er than the corresponding level in the control group(P=0.001).The horizontal bone resorption rate at 2 mm below the alveolar ridge of each group was significantly higher than that at 4 mm below the alveolar ridge in corresponding groups(P=0.003).Conclusion The space stabilizing device used in this study has a positive clinical impact on preserving space stability and minimizing bone resorption.
