Abstract

According to the authors' clinical experience, malocclusion accompanied by temporomandibular joint disorder involves mainly cross bite, open bite, deep overbite or axillary protrusion. However, it is possible that the symptoms of this disorder are associated with other types of malocclusion or even with nearly normal occlusion. In fact, it can be said that temporomandibular joint disorder may develop with any type of occlusion. This paper reports a case of open bite accompanied by temporomandibular joint disorder occurring in a patient who visited our hospital because of pain in the left temporomandibular joint region, vertigo and partial deafness. In this patient, the temporomandibular symptoms disappeared after orthodontic treatment. The patient received no particular treatment thereafter because follow-up observation confirmed that the therapeutic results were favorable without any relapse of the symptoms of temporomandibular disorder. The positions of the temporomandibular joint and mandibular condyle were determined in lateral-oblique radiograms obtained using our radiographic system, by which the mandibular condyle is radiographed using a projection consistent with its long axis.

开放性咬伤伴颞下颌关节紊乱1例。侧斜位x线片治疗前后咬合情况的比较。
根据笔者的临床经验,错牙合合并颞下颌关节紊乱主要表现为交叉咬合、开放咬合、深覆盖咬合或腋窝前突。然而,这种疾病的症状可能与其他类型的错牙合有关,甚至与几乎正常的咬合有关。事实上,可以说任何类型的咬合都可能导致颞下颌关节紊乱。本文报告一例因左侧颞下颌关节区疼痛、眩晕和部分耳聋而来我院就诊的患者,其开放性咬伤伴颞下颌关节紊乱。本例患者经正畸治疗后,颞下颌症状消失。患者此后未接受特殊治疗,因随访观察治疗效果良好,未见颞下颌紊乱症状复发。颞下颌关节和下颌髁的位置是通过使用我们的放射照相系统获得的侧斜x线片确定的,通过该x线片,下颌髁使用与其长轴一致的投影进行放射照相。
