The authors conducted research to determine the structural relationships of the craniomandibular articulation that resulted when a mandibular reference position was established. A noninvasive clinical method was used to identify and record centric maxillomandibular relation in normal subjects and a suitable reference position in subjects with derangements of the craniomandibular articulation. The reference positions were checked for repeatability. Magnetic resonance imaging was used to determine the intraarticular relationships resulting from application of the clinical techniques. The normal subjects conformed well to the 1987 "Glossary of Prosthodontic Terms" definition, with the mandible close to first-tooth contact. In subjects with deranged articulations, the condyle was always in an abnormal relationship on the affected side in the reference position, and there were many intersubject variations.
作者开展研究以确定在确立下颌参考位置时颅下颌关节的结构关系。采用一种非侵入性临床方法来识别和记录正常受试者的正中上颌下颌关系以及颅下颌关节紊乱受试者的合适参考位置。对参考位置进行了重复性检查。使用磁共振成像来确定应用临床技术后关节内的关系。正常受试者与1987年《口腔修复学术语词汇表》的定义非常相符，下颌接近首次牙齿接触。在关节紊乱的受试者中，在参考位置时患侧髁突总是处于异常关系，并且受试者之间存在许多差异。
