摘要

目的:本研究旨在利用锥形束计算机断层扫描(CBCT)对前开咬(AOB)患者的咽部气道间隙(PAS)进行三维评价，并与正常咬合患者进行比较。方法:开放咬合组(OBG, n = 25)由前牙覆盖3 mm以下的患者组成，对照组(n = 25)由年龄和性别匹配的患者组成，前牙覆盖1-3 mm，角I类错颌(1°≤a -nasion点- B点角≤4°)，正常轮廓(22°≤法兰克福下颌平面角≤28°)。将CBCT数据重建成三维图像后，将PAS分割成四个部分，并测量每个部分的体积。同时测量咽气道长度(PAL)及缩窄最小部位的面积和横向宽度。Pearson相关分析评价PAS变化与前牙覆合量的相关性。结果:OBG显示鼻咽、下咽和总气道容积明显变窄。OBG也显示了一个显着较小的面积和横向宽度的部分与最小的收缩。OBG显示明显较长的PAL，但前覆合的数量与PAS的变化没有相关性。结论:PAS与AOB相关。AOB患者PAS较窄，部分较小，收缩最小。

Three-dimensional evaluation of the pharyngeal airway space in patients with anterior open bite.

Objective: : This study aimed to three-dimensionally evaluate the pharyngeal airway space (PAS) of patients with anterior open bite (AOB) by using cone-beam computed tomography (CBCT) and compare the findings with those obtained in individuals with normal occlusion.

Methods: : The open bite group (OBG, n = 25) consisted of patients with an anterior overbite of -3 mm or less, while the control group (n = 25) consisted of age- and sex-matched individuals with an anterior overbite of 1-3 mm, Angle Class I malocclusion (1° ≤ point A-nasion-point B angle ≤ 4°), and a normodivergent profile (22° ≤ Frankfort mandibular plane angle ≤ 28°). After the CBCT data were reconstructed into a three-dimensional image, the PAS was segmented into four parts, and the volume of each part was measured. Pharyngeal airway length (PAL) and the area and transverse width of the part showing minimal constriction were also measured. Pearson's correlation analysis was used to evaluate the correlation between changes in the PAS and the amount of anterior overbite.

Results: : The OBG showed a significantly narrower airway space in the nasopharyngeal, hypopharyngeal, and total airway volumes. The OBG also showed a significantly smaller area and transverse width of the part with minimal constriction. The OBG showed a significantly longer PAL, but there was no correlation between the amount of anterior overbite and the changes in PAS.

Conclusions: : The PAS was associated with AOB. Patients with AOB had a narrower PAS and a smaller part showing minimal constriction.

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
