To identify differences in occlusal curvatures and maxillary arch dimensions between subjects with signs and symptoms of temporomandibular disorders TMDs and asymptomatic subjects.
One hundred subjects 78 female and 22 male who consented to participate in this research were examined for signs and symptoms of TMDs according to the guidelines of the Research Diagnostic Criteria for Temporomandibular Disorders RDCTMD. In addition, occlusal measurements were performed for all subjects on plaster models. All statistical analyses were performed with SPSS version 19.
Significant associations were revealed between the depth of the curve of Spee COS and temporomandibular joint TMJ sounds. Furthermore, maxillary arch width was negatively correlated to the steepness of the curve of Wilson. No differences were found between subjects with and without a history of orthodontic treatment.
Subjects with TMJ sounds tend to have a flatter COS compared to subjects without TMJ sounds.
比较有颞下颌关节紊乱病（TMD）症状和无症状患者的咬合曲线和上颌弓尺寸的差异。
共 100 名受试者（78 名女性和 22 名男性），根据颞下颌关节紊乱病研究诊断标准（RDCTMD）的指南，对他们进行 TMD 症状和体征的检查。此外，所有受试者的石膏模型都进行了咬合测量。所有统计分析均使用 SPSS 版本 19 进行。
Spee 曲线深度（COS）与颞下颌关节（TMJ）声音之间存在显著相关性。此外，上颌弓宽度与 Wilson 曲线的陡峭度呈负相关。有和没有正畸治疗史的受试者之间没有差异。
与没有 TMJ 声音的受试者相比，有 TMJ 声音的受试者的 COS 更平坦。
