In this study subjects with shortened dental arches (SDA, n = 60), characterized by the absence of molar support, are compared with subjects with a complete dentition (n = 72) with respect to signs and symptoms of mandibular dysfunction. The subjective examination consisted of questions related to pain, noises within the joints and mobility of the lower jaw. The objective examination consisted of the registration of clicking of the temporomandibular joint (TMJ) by bilateral palpation and measuring the maximal mouth opening. In spite of the finding that significantly more subjects of the SDA group under 40 years of age reported pain in or around the TMJ, it is concluded that in the population studied no convincing evidence was found that a SDA provokes signs and symptoms of mandibular dysfunction.
在本研究中，将以无磨牙支持为特征的牙弓缩短受试者（SDA，n = 60）与全牙列受试者（n = 72）在颞下颌关节紊乱的体征和症状方面进行比较。主观检查包括与疼痛、关节弹响和下颌活动度相关的问题。客观检查包括通过双侧触诊记录颞下颌关节（TMJ）弹响以及测量最大开口度。尽管发现SDA组中40岁以下的受试者报告TMJ内或其周围疼痛的人数明显更多，但得出的结论是，在所研究的人群中，没有找到令人信服的证据表明SDA会引发颞下颌关节紊乱的体征和症状。
