摘要
目的:探讨反与颞下颌关节结构紊乱病的相关性。方法:收集59例,诊断为颞下颌关节结构紊乱病伴反患者。将颞下颌关节结构紊乱病患者分为可复性关节盘移位、不可复性关节盘移位。根据反牙位、反牙形态功能、反牙数目、反牙相对中线关系分组,运用SPSS22.0软件对数据行卡方分析。结果:反牙位与颞下颌关节结构紊乱病有关,前后牙均有反的颞下颌关节结构紊乱病患者与不可复性关节盘移位有关(P<0.05);其余分类均无相关性。结论:反牙位是颞下颌关节结构紊乱病的潜在影响因素,疲劳易诱发关节结构紊乱。
Objective：To investigate the correlation between crossbite and temporomandibular joint disc displacement（DD）.Methods：Fifty-nine cases were collected,who were diagnosed as DD with crossbite.The patients with DD were divided into disc displacement with reduction and disc displacement without reduction.They were classified in terms of the crossbite tooth location,morphological function,crossbite tooth number,and relative median line of crossbite tooth.The data were analyzed with SPSS22.0 software package and X2 test.Results：There was a significant correlation between crossbite tooth position and DD.Crossbite in anterior and posterior teeth had a high incidence of disc displacement without reduction（P〈0.05）.The other classification were no significance.Conclusion：Crossbite might be a risk factor in DD,and bite fatigue might induce DD.
