摘要/Abstract

摘要： 目的： 探讨骨皮质切开在辅助关闭因牙槽骨萎缩引起间隙关闭困难病例中的临床意义。方法： 选取尖牙远移速度小于0.2 mm/月的病例24例，12例进行骨皮质切开术，12例作为对照组。2组均采用微种植钉支抗滑动法关闭间隙。采用SPSS 13.0软件包对数据进行t检验。结果： 所有病例均关闭拔牙间隙，实验组尖牙远移速度显著优于对照组（P<0.05），尖牙远移更接近整体移动（P<0.05）；间隙关闭后尖牙远中未见明显软组织折痕（P<0.05），但尖牙远中龈沟深度和对照组无显著差异（P>0.05）。结论： 对于牙槽骨萎缩引起的较难关闭的拔牙间隙，骨皮质切开具有积极作用。

Abstract: PURPOSE: To study the effect of corticotomy in assisting space closure in cases whose alveolar ridge atrophy was obvious after extraction. METHODS: Twenty two cases whose canine's distal movement<0.2mm/m were selected, 12 accepted corticotomy and the other 12 were selected as the control group. All the spaces were closed with sliding mechanics under the help of microscrews. SPSS 13.0 software package was used for statistical analysis. RESULTS: All the spaces were closed. The canine's movement speed in the experimental group was superior to the control group(P<0.05), and the canine's movement was almost bodily movement (P<0.05); there was no obvious gingiva fold after space closure (P<0.05). There was no significant difference in the sulcus depth on the distal surface of the upper canine(P>0.05). CONCLUSIONS: Corticotomy is helpful to space closure in cases with significant alveolar ridge atrophy.
