Disagreement exists regarding the relationship between occlusal interferences and temporomandibular joint dysfunction (TMD). This study sought to determine how a balanced occlusion, providing uniform contact in centric relation, would affect signs and symptoms of TMD. A randomly chosen group of 60 patients with occlusal interferences and signs and symptoms of TMD used a mandibular orthotic to balance their occlusions at centric relation (CR). When the occlusions of symptomatic patients were balanced in CR, there was a significant reduction or elimination of TMD complaints, suggesting a relationship between balancing occlusion in CR and optimum management of TMD.
关于咬合干扰与颞下颌关节紊乱病（TMD）之间的关系存在分歧。本研究旨在确定在正中关系下提供均匀接触的平衡咬合如何影响TMD的体征和症状。随机选取60名有咬合干扰及TMD体征和症状的患者，使用下颌矫正器使他们在正中关系（CR）下的咬合达到平衡。当有症状患者的咬合在CR中达到平衡时，TMD相关主诉显著减少或消除，这表明在CR中平衡咬合与TMD的最佳治疗之间存在关联。
