The purpose of this study was to investigate the prevalence of temporomandibular disorders (TMD) in denture wearers and the association between prosthetic factors and this condition.
There is no consensus about the relationship between prosthetic factors and TMD among denture wearers.
The sample was composed of 92 patients wearing both maxillary and mandibular complete dentures. The Research Diagnostic Criteria for TMD (RDC/TMD) were adopted for patient examination. Objective evaluation of denture quality was determined by analysis of retention and stability of mandibular denture, interocclusal distance, articulation and occlusion. Association between denture quality and TMD diagnosis was analysed using chi-square and Fisher's exact tests.
37.4% of the patients presented TMD. Denture quality was not significantly associated with the presence of TMD: mandibular retention (p = 0.466); mandibular stability (p = 0.466); interocclusal distance (p = 0.328); centric relation (p = 0.175); and balanced occlusion (p = 0.56).
Within the scope of this case-controlled cross-sectional study, no robust association between prosthetic factors and TMD was found.
本研究旨在调查义齿佩戴者颞下颌关节紊乱病（TMD）的患病率以及修复因素与该病症之间的关联。
关于义齿佩戴者修复因素与TMD之间的关系尚无共识。
样本由92名佩戴上颌和下颌全口义齿的患者组成。采用颞下颌关节紊乱病研究诊断标准（RDC/TMD）对患者进行检查。通过分析下颌义齿的固位和稳定性、颌间距离、咬合和牙合关系来对义齿质量进行客观评估。使用卡方检验和费舍尔精确检验分析义齿质量与TMD诊断之间的关联。
37.4%的患者患有TMD。义齿质量与TMD的存在无显著关联：下颌固位（p = 0.466）；下颌稳定性（p = 0.466）；颌间距离（p = 0.328）；正中关系（p = 0.175）；以及平衡牙合（p = 0.56）。
在本病例对照横断面研究范围内，未发现修复因素与TMD之间存在紧密关联。
