This study aimed to determine the possible association between disc displacement (DD) disorders and malocclusion complexity. This cross-sectional study was carried out using a case-control design. The Research Diagnosis Criteria for Temporomandibular Disorders were used to identify cases and controls. The Index of Complexity, Outcome, and Need (ICON) was used to quantify malocclusion complexity as easy, mild, moderate, difficult, or very difficult. A total of 310 subjects were included: 130 cases and 180 controls. A binary logistic regression ( < 0.05) was used to identify associations. The odds ratio (OR) was also calculated. DD was associated with sex, age, and malocclusion complexity ( < 0.05). The malocclusion complexity comparison showed that 89.3% of the controls fell within the easy-moderate levels of the ICON, whereas 85.4% of the cases were in the moderate-very difficult levels ( ≤ 0.001). Difficult and very difficult malocclusions had high ORs (9.801 and 9.689, respectively) compared to the easy cases. In conclusion, patients with malocclusion complexity levels classified as difficult or very difficult have greater odds of presenting DD.
本研究旨在确定盘移位（DD）紊乱与错牙合复杂性之间可能存在的关联。本横断面研究采用病例对照设计进行。使用颞下颌关节紊乱病研究诊断标准来确定病例和对照。使用复杂性、结果和需求指数（ICON）将错牙合复杂性量化为容易、轻度、中度、困难或非常困难。总共纳入了310名受试者：130例病例和180名对照。采用二元逻辑回归（<0.05）来确定关联。还计算了比值比（OR）。DD与性别、年龄和错牙合复杂性相关（<0.05）。错牙合复杂性比较显示，89.3%的对照处于ICON的容易 - 中度水平，而85.4%的病例处于中度 - 非常困难水平（≤0.001）。与容易的病例相比，困难和非常困难的错牙合具有较高的OR值（分别为9.801和9.689）。总之，错牙合复杂性水平被分类为困难或非常困难的患者出现DD的几率更高。
