摘要
目的:我们旨在全面分析成年人骨骼畸形、性别和下颌骨特征在所有三个维度上可能存在的相关性,并确定极端骨骼模式的典型下颌骨特征:根据现有的计算机断层扫描或锥束计算机断层扫描扫描结果,计算出 111 名成年患者(平均年龄为 27.0 ± 10.2 岁;49 名女性,62 名男性)的头骨三维模型。根据三维模型,从以下几个方面对骨骼形态进行了检查:(a)横向维度,根据menton偏差进行不对称检查;(b)矢状维度,根据Wits评估结果进行不对称检查;(c)纵向维度,根据上下颌平面角度进行不对称检查。评估的下颌骨特征包括线性(腮高和腮宽、腮体长度)、角度(腮、腮和腮体角度)和体积(腮/下颌体积、腮体/下颌体积)参数:横向骨骼不对称与下颌骨特征之间未发现相关性,而矢状(F(16, 174) = 3.32, p 2 = 0.23)和垂直(F(16, 174) = 3.18, p 2 = 0.23)骨骼模式对下颌骨有显著影响。性别与下颌骨特征的相关性与骨骼形态无关。判别分析显示,II级和III级患者在颌骨和颌骨体角度方面存在差异,II级患者的角度更高(颌骨角度:II级=89.8 ± 3.9° vs. III级=84.4 ± 4.8°;颌骨体角度:II级=87.7 ± 4.8° vs. III级=82.1 ± 5.2°)。根据盂角、体角和体/下颌体积对低发散和高发散患者进行区分,高发散患者的盂角、体角和体/下颌体积更大(盂角:低发散 = 114 ± 9.3° vs. Hyperdivergent = 126.4 ± 8.6°; body angle: hypodivergent = 82.9 ± 4.4° vs. Hyperdivergent = 87.7 ± 6.5°; body/mandibular volume: hypodivergent = 72.4 ± 2.7% vs. Hyperdivergent = 76.2 ± 2.6%):在分析成人患者的三维数据以制定治疗计划时,正畸医生应注意下颌骨的角度和体积特征,以识别极端的骨骼矢状或垂直畸形。
Three-dimensional mandibular characteristics in skeletal malocclusion : A cross-sectional study.
Purpose: We aimed to comprehensively analyse a possible correlation between skeletal malocclusions, gender and mandibular characteristics in all three dimensions in adults and to identify mandibular characteristics that are typical for extreme skeletal patterns.
Methods: A 3D model of the skull was calculated in 111 adult patients (mean age = 27.0 ± 10.2 years; 49 women, 62 men) from available computed tomography or cone beam computed tomography scans of their heads. Based on the 3D models, the skeletal patterns were examined in (a) the transversal dimension regarding asymmetry according to menton deviation, (b) the sagittal dimension according to the Wits appraisal and (c) the vertical dimension according to the maxillomandibular plane angle. The mandibular characteristics assessed were linear (ramus height and width, body length), angular (ramus, gonial and body angle) and volumetric (ramus/mandibular volume, body/mandibular volume) parameters.
Results: No correlation between transversal skeletal asymmetry and mandibular characteristics were found, while sagittal (F(16, 174) = 3.32, p < 0.001, η2 = 0.23) and vertical (F(16, 174) = 3.18, p < 0.001, η2 = 0.23) skeletal patterns were shown to have a significant effect on the mandible. Gender correlated with mandibular characteristics independently from the skeletal pattern. Discriminant analysis revealed that class II and III patients differed in ramus and body angle with class II patients showing higher angles (ramus angle: class II = 89.8 ± 3.9° vs. class III = 84.4 ± 4.8°; body angle: class II = 87.7 ± 4.8° vs. class III = 82.1 ± 5.2°). Hypo- and hyperdivergent patients were discriminated by gonial angle, body angle and body/mandibular volume with hyperdivergent patients having a greater gonial and body angle and body/mandibular volume (gonial angle: hypodivergent = 114 ± 9.3° vs. hyperdivergent = 126.4 ± 8.6°; body angle: hypodivergent = 82.9 ± 4.4° vs. hyperdivergent = 87.7 ± 6.5°; body/mandibular volume: hypodivergent = 72.4 ± 2.7% vs. hyperdivergent = 76.2 ± 2.6%).
Conclusion: When analysing 3D data for treatment planning of adult patients, the orthodontist should pay attention to angular and volumetric characteristics of the mandible to identify extreme skeletal sagittal or vertical malocclusions.
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.
