摘　　要：目的:运用三维空间测量法研究骨性Ⅱ类安氏Ⅱ类2分类患者颞下颌关节的三维空间形态、位置及生长发育的相关趋势。方法:纳入骨性Ⅰ类安氏Ⅰ类患者42例与骨性Ⅱ类安氏II类2分类患者47例,拍摄CBCT,采用Mimics21.0重建颞下颌关节三维模型,在三维模型上测量关节前间隙、关节上间隙等14个测量项目,并进行比较。结果:男性患者的髁突普遍比女性患者的大,而安氏Ⅱ类2分类患者随年龄的增长,髁突内外径及前后径逐渐增大,但髁突高度、关节窝大小及形态等均在青少年时期就已接近成年时的大小,在成年患者与未成年患者中并无显著差异。相对于安氏Ⅰ类患者,安氏Ⅱ类2分类患者的关节窝宽度更小,髁突体积及表面积均更小,且髁突位置多处于后退位。结论:骨性Ⅱ类安氏Ⅱ类2分类患者与骨性Ⅰ类安氏Ⅰ类患者的关节窝形态、髁突形态及位置、生长发育趋势均有一定差异。Objective:To study the 3D spatial morphology,location and growth trend of temporomandibular joint(TMJ)in patients with ClassⅡdivision 2 by 3D spatial measurement method.Methods:47 classⅡdivision 2 patients and 42 ClassⅠpatients were included.The 3D model of TMJ was reconstructed by Mimics21.0.14 indexes such as anterior,upper and posterior space were measured directly on the 3D model and compared between the 2 groups of patients.Results:The condyle size of the male patients was generally larger than that of the female patients.The condyle size gradually increased with the increase of age in the patients of ClassⅡdivision 2.However,the size and shape of the fossa and the height of the condyle were close to the final size in the early stage,and there was no significant difference between adult and juvenile patients.The fossa width,condyle volume and surface area were smaller,and the condyle position was mostly in a recessive position in ClassⅡdivision 2 patients compared with ClassⅠpatients.Conclusion:The fossa shape,condylar shape and location,and growth trend are different between ClassⅡdivision 2 and ClassⅠpatients.
