摘要
安氏Ⅲ类错颌畸形是临床上常见的错颌畸形之一,通常表现为上下颌第一磨牙近中关系、前牙反牙合,严重影响了面部发育、口腔功能和颜面美观。研究发现反牙合牙位是颞下颌关节紊乱病的潜在影响因素,因此对安氏Ⅲ类错颌畸形患者的颞下颌关节进行检查对临床诊疗和评估是有指导意义的。磁共振成像(MRI)是一种无创伤、无辐射技术,可多序列、多方位成像,并很好地显示关节结构及周围软组织情况,被认为是颞下颌关节(TMJ)软组织成分成像的金标准,已成为颞下颌关节区域的首选检查方法。本文就TMJ应用MRI检查的特点、方法、TMJ的MRI影像与TMJ其他影像学检查方法的比较作一综述。
Angle classⅢmalocclusion is one of the most common clinical malocclusion.It usually shows the mesial relationship between the upper and lower mandibular first molars and the anterior teeth reflex,which seriously affects facial development,oral function and facial aesthetics.The study found that the reverse tooth position is a potential influencing factor of temporomandibular joint disorder.Therefore,the examination of the temporomandibular joint in patients with Angle classⅢmalocclusion is instructive for clinical diagnosis and evaluation.Magnetic resonance imaging(MRI)is a non-invasive,non-radiative technology that can image multiple sequences and multiple orientations,and well displays the joint structure and surrounding soft tissue.It is considered to be the gold standard for imaging the soft tissue components of the temporomandibular joint(TMJ),has become the preferred method of examination of the temporomandibular joint area.This article reviews the characteristics and methods of TMJ application MRI examination,and compares TMJ MRI images with TMJ other imaging examination methods.
