Abstract

Abstract Objectives The objective of the present study was to compare the dentoskeletal effects of mini-screw-assisted rapid maxillary expansion (RME) in children with different body mass index (BMI) percentiles. Study design The study was performed on 20 patients who were divided into two groups based on their BMI percentiles as normal-weight (n = 10) and overweight-obese (n = 10). The linear, angular and area analyses were performed on lateral and postero-anterior cephalometric radiographs and three-dimensional dental models before and after RME therapy. Results A statistically significant increase was observed in maxillary intermolar and intercanine distances and palatal area measurements in both groups (P < 0.05). There was no significant difference between the two groups when dental RME changes were measured on 3D models. A significant difference was observed in latero-nasal and maxillo-mandibular width as well as postero-anterior cephalometric parameters between the groups (P < 0.05). While a significant change was observed in the SN-GoMe, FMA, Z angle, Wits appraisal, total anterior facial height and lower anterior facial height parameters in the normal-weight group (P < 0.05), a statistically significant change was observed in the gonial and nasolabial angles in the overweight-obese group. Conclusions Mini-screw-assisted RME treatment significantly increased maxillary intermolar and intercanine width, and the palatal area in both groups; however, there was no significant difference between the BMI groups.

一项前瞻性临床研究:不同体重指数青少年微型螺钉辅助上颌快速扩张的比较

摘要目的本研究的目的是比较不同体重指数（BMI）百分位数儿童上颌骨微型螺钉辅助快速扩张（RME）的牙骨骼效果。研究设计这项研究对20名患者进行了研究，他们根据BMI百分位数分为两组，即正常体重（n=10）和超重肥胖（n=10）。在RME治疗前后，对侧前方和后前方的头影测量X线片和三维牙齿模型进行线性、角度和面积分析。结果两组上颌齿间距离、齿间距离和腭面积测量值均有统计学意义（P<0.05），在三维模型上测量牙齿RME变化时，两组差异无统计学意义。两组间鼻后宽度、上下颌宽度及前后头影测量参数差异有统计学意义（P＜0.05），正常体重组SN GoMe、FMA、Z角、Wits评价、前面部总高度及前面部下高度参数变化有统计学意义，超重肥胖组的角和鼻唇角有统计学意义的变化。结论微型螺钉辅助RME治疗可显著增加两组上颌齿间宽度、齿间宽度和腭面积；然而，BMI组之间没有显著差异。

期刊介绍： The Australasian Orthodontic Journal (AOJ) is the official scientific publication of the Australian Society of Orthodontists. Previously titled the Australian Orthodontic Journal, the name of the publication was changed in 2017 to provide the region with additional representation because of a substantial increase in the number of submitted overseas'' manuscripts. The volume and issue numbers continue in sequence and only the ISSN numbers have been updated. The AOJ publishes original research papers, clinical reports, book reviews, abstracts from other journals, and other material which is of interest to orthodontists and is in the interest of their continuing education. It is published twice a year in November and May. The AOJ is indexed and abstracted by Science Citation Index Expanded (SciSearch) and Journal Citation Reports/Science Edition.
