概括

细分LeFort I骨切术会导致牙的根部再吸收. 然而,再吸收的增加与单独的正牙治疗没有显著差异,并且在临床上无关紧要.

科学领域:

牙科牙科是指牙科的专业.
矯正牙科矯正牙科是一種矯正牙科.
口腔和牙面部外科手术

背景情况:

细分LeFort I骨切除术是一种用于正牙的手术程序,用于纠正大变形.
根吸收是正牙治疗和正牙手术的潜在并发症.

研究的目的:

为了评估根部再吸收的发生率和严重程度,上牙邻 osteotomy 网站的细分LeFort I骨切除术后.
为了比较经过细分LeFort I骨切除术与正牙治疗的患者和仅接受正牙治疗的患者之间的根吸收.

主要方法:

在三个时间点 (手术前/治疗,手术后/治疗和长期随访) 分析了18名手术患者和16名对照患者的形束计算断层扫描 (CBCT) 扫描.
用重复测量ANOVA测量和分析腹中央切口的根体积,表面积和长度,犬和第一牙.
统计学意义被设定为p<0.05.05.

主要成果:

随着时间的推移,手术组的根吸收 (长度,体积和表面积) 呈现出统计学上显著的增加.
在手术组和对照组之间没有观察到根吸收的显著差异,除了一些变量.

结论:

分段性LeFort I骨切除术与正牙治疗相结合,可诱导根部再吸收.
在联合治疗和单独的正牙治疗之间观察到的根再吸收差异不是统计学上显著的,也不是临床上显著的.
