摘要

目的评估并比较骨骼等级为 II 的患者在使用固定功能矫治器--Herbst 和 AdvanSync™ (Ormco,Orange,CA,USA)矫治器治疗后,咽部气道和舌间隙在治疗前和治疗后侧位头相图上的变化:在这项随机对照试验中,40 名患者(21 名男性,19 名女性)被分为两组--Herbst 组(平均年龄为 12.6±0.67 岁)和 AdvanSync 组(平均年龄为 12.8±0.66 岁)。治疗前和治疗后(矫治器疗程-8 个月)的侧位头影均使用软件程序进行描记,以评估咽部气道和舌间隙的变化:结果:Herbst 组的鼻咽气道、velopharyngeal 气道、舌咽气道和下咽气道分别增加了 2.12 毫米(p ≤ 0.001)、2.33 毫米(p ≤ 0.001)、2.40 毫米(p ≤ 0.01)和 1.57 毫米(p ≤ 0.05),而 AdvanSync 组分别增加了 1.89 毫米(p ≤ 0.001)、1.21 毫米(p ≤ 0.001)、1.18 毫米(p ≤ 0.001)和 1.53 毫米(p ≤ 0.001)。Herbst 组的舌长和舌高分别增加了 2.04 毫米(p ≤ 0.01)和 3.74 毫米(p ≤ 0.001),而 AdvanSync 组的数值分别为 2.41 毫米(p ≤ 0.05)和 2.69 毫米(p ≤ 0.001)。Herbst 组的舌尖与下咬合面的距离变化为 0.69 毫米(p ≤ 0.001),AdvanSync 组的舌尖与下咬合面的距离变化为 0.77 毫米(p ≤ 0.001)。咽后气道尺寸与舌后口咽气道尺寸呈正相关,而舌后口咽气道尺寸与喉咽气道尺寸呈正相关,喉咽气道尺寸与舌尖距下咬合平面的距离呈良好相关:结论:在本研究中,两个治疗组的气道尺寸和舌参数都有明显增加。除舌尖与下咬合面的距离外,Herbst矫治器组的这些变化高于AdvanSync组。只有在腭后口咽气道方面发现了咽气道之间的明显差异。

Cephalometric evaluation of pharyngeal airway and tongue space following treatment with Herbst and AdvanSync appliances : A prospective randomized clinical trial.

Cephalometric evaluation of pharyngeal airway and tongue space following treatment with Herbst and AdvanSync appliances : A prospective randomized clinical trial.

Objectives: To evaluate and compare pharyngeal airway and tongue space changes after treatment with fixed functional appliances-Herbst and AdvanSync™ (Ormco, Orange, CA, USA) appliances-in skeletal class II patients in pre- and posttreatment lateral cephalograms.

Methods: For this randomized, controlled trial, 40 patients (21 male, 19 female) were divided into two groups-a Herbst group (mean age 12.6 ± 0.67 years) and an AdvanSync group (mean age 12.8 ± 0.66 years). Pre- and posttreatment (appliance therapy duration-8 months) lateral cephalograms were traced using a software program to evaluate pharyngeal airway and tongue space changes.

Results: Nasopharyngeal airway, velopharyngeal airway, glossopharyngeal airway, and hypopharyngeal airway increased in the Herbst group by 2.12 mm (p ≤ 0.001), 2.33 mm (p ≤ 0.001), 2.40 mm (p ≤ 0.01), and 1.57 mm (p ≤ 0.05), while in the AdvanSync group the increases were 1.89 mm (p ≤ 0.001), 1.21 mm (p ≤ 0.001), 1.18 mm (p ≤ 0.001), and 1.53 mm (p ≤ 0.001), respectively. In the Herbst group, tongue length and height increases were 2.04 mm (p ≤ 0.01) and 3.74 mm (p ≤ 0.001), while the values in the AdvanSync group were 2.41 mm (p ≤ 0.05) and 2.69 mm (p ≤ 0.001). The change of the tongue tip from the lower occlusal plane was 0.69 mm (p ≤ 0.001) in the Herbst group and 0.77 mm (p ≤ 0.001) in the AdvanSync group. The velopharyngeal airway dimension was correlated positively with that of the retroglossal oropharyngeal airway, which in-turn positively correlated with the laryngopharyngeal airway which correlated well with the distance of the tongue tip from the lower occlusal plane.

Conclusions: The airway dimensions and tongue parameters increased significantly in both treatment groups in the present study. These changes were higher in the Herbst appliance than in the AdvanSync group, except for the distance of the tongue tip from the lower occlusal plane. A significant difference between the pharyngeal airways was found only for the retropalatal oropharyngeal airway.

期刊介绍: The Journal of Orofacial Orthopedics provides orthodontists and dentists who are also actively interested in orthodontics, whether in university clinics or private practice, with highly authoritative and up-to-date information based on experimental and clinical research. The journal is one of the leading publications for the promulgation of the results of original work both in the areas of scientific and clinical orthodontics and related areas. All articles undergo peer review before publication. The German Society of Orthodontics (DGKFO) also publishes in the journal important communications, statements and announcements.
