This study aimed to investigate the correlation between mandibular deviation (MD) and possible clinical factors in patients with anterior disc displacement (ADD). This retrospective clinical study enrolled 296 patients with ADD, diagnosed using magnetic resonance imaging, from 2015 to 2018. The clinical symptoms and medical histories of these patients were carefully examined and recorded. Mandibular deviation was the primary outcome variable confirmed by a combination of clinical examination and facial photographs or posteroanterior cephalograms. The primary predictor variable was ADD staging. Secondary predictor variables included condylar height and distance of disc displacement. Other predictor variables were age, sex, disease course, oral parafunctions, depression, and bone mineral density. We used logistic regression to examine the correlation between the MD and all predictor variables. The χ2 test and analysis of variance were used to exclude the correlation between the predictor variables. In this study, the prevalence of MD was 77% among 278 patients with ADD. Bilateral ADD staging significantly contributed to MD on both sides. The odds ratio increased with the deterioration of disc displacement. The present study demonstrated that the ADD staging influences the condylar height and MD, and that articular disk position should be considered while treating MD.
本研究旨在探讨患有前牙盘移位（ADD）的患者下颌偏斜（MD）与可能的临床因素之间的相关性。本回顾性临床研究纳入了 2015 年至 2018 年间经磁共振成像（MRI）诊断为 ADD 的 296 例患者。仔细检查并记录了这些患者的临床症状和病史。下颌偏斜是通过临床检查和面部照片或前后颅面侧位片相结合来确认的主要结局变量。主要预测变量是 ADD 分期。次要预测变量包括髁突高度和盘移位距离。其他预测变量包括年龄、性别、病程、口腔功能障碍、抑郁和骨密度。我们使用逻辑回归来检查 MD 与所有预测变量之间的相关性。使用卡方检验和方差分析排除了预测变量之间的相关性。在这项研究中，278 例 ADD 患者中有 77%存在 MD。双侧 ADD 分期对双侧 MD 有显著影响。随着盘移位恶化，比值比增加。本研究表明，ADD 分期影响髁突高度和 MD，在治疗 MD 时应考虑关节盘位置。
