本研究的目的是比较差异开口扩张器（EDO）和扇形扩张器（FE）的上颌牙颌效果。48例替牙期上颌牙弓狭窄患者随机分为EDO组和FE组。在扩张前后采集锥形束计算机断层扫描。使用ITK-SNAP和3D Slicer软件评估颅底重叠后的线性和角度三维变化。组间比较采用T检验或Mann-Whitney U检验（P<0.05）。EDO组包括24例接受EDO治疗的患者（13例女性，11例男性; 7.6岁）。FE组包括24例接受FE治疗的患者（14例女性，10例男性; 7.8岁）。EDO组的颅骨外侧位移更大，眼眶、鼻腔、颧骨和腭区的扩张更大（组间平均差异分别为0.4、0.8、0.9和1.1 mm）。FE组的尖牙间扩张和尖牙颊侧倾斜度更大，而EDO组的磨牙间距离变化和磨牙颊侧倾斜度更大。垂直和前后位移和腭平面旋转观察到类似的变化。与FE相比，EDO产生了更大的横向骨骼扩张，具有相似的垂直和前后效应。牙齿的变化更大的磨牙区的患者与EDO和犬齿区的患者与FE治疗。EDO和FE能够在混合牙列中产生骨骼变化。两种扩张器的选择取决于磨牙区和鼻上颌复合体所需的扩张量。该试验在ClinicalTrials.gov上注册，标识符为NCT 03705871。
The aim of this study was to compare the maxillary dentoskeletal outcomes of the expander with differential opening (EDO) and the fan-type expander (FE). Forty-eight patients with maxillary arch constriction in the mixed dentition were randomly allocated into EDO and FE groups. Cone-beam computed tomography scans were acquired before and after expansion. Linear and angular three-dimensional changes were assessed after cranial base superimposition using the ITK-SNAP and the 3D Slicer software. T or Mann-Whitney U tests were used for intergroup comparisons (P<0.05). The EDO group comprised 24 patients treated with the EDO (13 female, 11 male; 7.6 years). The FE group comprised 24 patients treated with the FE (14 female, 10 male; 7.8 years). Skeletal lateral displacements were greater in the EDO group with greater expansion in the orbital, nasal cavity, zygomatic bone, and palate regions (mean intergroup differences of 0.4, 0.8, 0.9, and 1.1 mm, respectively). Intercanine expansion and canine buccal inclination were greater in the FE group, while intermolar distance changes and molar buccal inclination were greater in the EDO group. Similar changes were observed for vertical and anteroposterior displacements and palatal plane rotation. The EDO produced greater transverse skeletal expansion compared to the FE, with similar vertical and anteroposterior effects. Dental changes were greater in the molar region for patients treated with the EDO and in the canine region for patients treated with the FE. The EDO and the FE are capable of producing skeletal changes in the mixed dentition. The decision between both expanders will depend on the amount of expansion required in the molar region and in the nasomaxillary complex. The trial was registered at ClinicalTrials.gov, under the identifier NCT03705871.
