摘要: 目的: 研究青少年安氏Ⅱ类亚类错牙合患者颞下颌关节的关节窝形态、髁突形态、髁突位置及关节间隙的锥形束CT(CBCT)表现,为临床诊疗提供参考。方法: 选择2018年6月—2019年12月来苏州口腔医院正畸科就诊的青少年安氏Ⅱ类亚类错牙合患者30例为实验组,青少年安氏Ⅰ类错牙合患者30例为对照组,比较2组患者关节长轴、关节短轴、髁突外嵴最突点到矢状中线距离、髁突水平角、关节内间隙、关节中间隙、关节外间隙、关节前间隙、关节上间隙、关节后间隙、髁突垂直高度、关节窝宽度、关节窝深度、关节结节后壁倾斜角及双侧髁突到水平线垂直距离差。采用SPSS 23.0软件包对数据进行统计学分析。结果: 实验组安氏Ⅱ类亚类错牙合患者中性侧与远中侧关节后间隙、髁突水平角、髁突垂直高度、关节窝宽度、关节窝深度、关节结节后壁倾斜角比较,差异均有显著意义(P<0.01);对照组安氏Ⅰ类错牙合患者左右两侧关节窝形态、髁突形态及髁突位置比较,差异均无统计学意义(P>0.05)。结论: 安氏Ⅱ类亚类错牙合患者可能在髁突位置、髁突形态及关节窝形态上与安氏Ⅰ类错牙合患者存在差异,正畸治疗中需对此类患者提高警惕,在临床初诊检查时应多关注颞下颌关节区的检查。

Abstract: PURPOSE: To evaluate the morphology and position of condyle and fossa and joint space of adolescent temporomandibular joint with Class Ⅱ subdivision malocclusion, in order to provide a reference for diagnosis before treatment. METHODS: The study sample consisted of 30 adolescent patients with Class Ⅱ subdivision malocclusions(9 males, 21 females, mean age 12.5 years) as the experimental group and 30 adolescent patients with Class Ⅰ malocclusions (11 males, 19 females, mean age 12 years) as the control group treated from June 2018 to December 2019 in Suzhou Stomatological Hospital. The long axis of condyle, short axis of condyle, the distance from the outer pole of condyle to sagittal midline, horizontal angle of condyle, Joint space(medial, inner, outer, anterior, superior, posterior), vertical height of condyle, width of joint fossa, depth of joint fossa, angle of posterior wall of the articular tubercle and vertical distance of bilateral condyle to horizontal line were measured on cone-beam CT(CBCT) images and analyzed with Dolphin Imaging 11.95. SPSS 23.0 software package was used for statistical analysis of the data. RESULTS: In Angle Class Ⅱ subdivision malocclusion patients, there were significant differences in posterior joint space, horizontal angle of condyle, vertical height of condyle, width of joint fossa, depth of joint fossa and angle of posterior wall of the articular tubercle between neutral side and distal side(P<0.01). In Angle Class Ⅰ malocclusion patients, there was no significant difference in joint fossa morphology, condyle morphology and condyle position between right side and left side (P>0.05). CONCLUSIONS: There may be differences in condyle position, condyle shape and joint fossa shape between patients with Class Ⅱ subdivision malocclusions and Class Ⅰ malocclusion patients. More attention should be paid to the temporomandibular joint in initial clinical examination and clinical orthodontic treatment.
