摘要

为了探讨颞下颌关节(TMJ)紊乱与咬合问题的关系,对149例(男54例,女95例)未经治疗的错颌畸形患者进行了颞下颌关节紊乱(TMJ)症状(关节噪声、疼痛和下颌运动障碍)的流行病学调查。结果表明:1)颞下颌关节病变发生率为33.6%,其中男性占27.8%,女性占36.8%。2)在有症状的被试中,颞下颌关节紊乱最常见的症状是关节噪音(76.0%),其次是关节疼痛(68.0%),第三是下颌运动障碍(38.0%)。3) 8岁以后TMJ疾病的发生率增加,15 ~ 18岁略有下降,19岁以后出现高频。这些变化可能与牙合结构的变化有关,如永久继位磨牙的脱落或第三磨牙的出现。4)对称前交叉咬合错颞下颌关节紊乱发生率低。而在后牙合错和下颌外侧移位的病例中,颞下颌关节紊乱的症状却很常见。这些结果提示下颌头侧移可能与颞下颌关节紊乱的发生有关。

[Incidence of temporomandibular joint disorders in patients with malocclusion].

In order to examine the relationship between the incidence of temporomandibular joint (TMJ) disorders and the occlusal problems, epidemiological surveys regarding the signs of TMJ disorders (joint noise, pain and disturbance of mandibular movement) were carried out to 149 untreated patients (54 males and 95 females) with malocclusion. The results indicated as follows: 1) Incidence of TMJ disorders was 33.6% of total samples, 27.8% of males and 36.8% of females. 2) In symptomatic subjects, the most frequent sign of TMJ disorders was joint noise (76.0%), the second was joint pain (68.0%) and the third was disturbance of mandibular movement (38.0%). 3) The incidence of TMJ disorders increased after 8 years of age, while it decreased slightly from 15 to 18 years of age and showed high frequency after 19 years of age. It was suggested that these changes were related with the occlusal configurations such as the exfoliation followed by the eruption of permanent successors or the eruption of the third molars. 4) Symmetrical anterior cross-bite malocclusion showed low incidence of TMJ disorders. In posterior cross-bite malocclusion and mandibular lateral displacement case, however, the signs of TMJ disorders were found frequently. These results suggested that the lateral shift of mandibular head in fossa may relate with the appearance of TMJ disorders.
