Abstract:
Objective:To study the morphological characteristics of temporo-mandibular joint with high angle vertical skeletal pattern in adult females with class II skeletal type.Methods:41 CBCT films of adult females (20 normal controls;21 skeletal class II high angle subjects)were collected.The position of and form of condyle,form of fossa and joint spaces were measured by Mimics 17.0 soft-ware.Results:Compared with the control group the condyles in high angle patients located more posterior.The joint fossae were lower. The angles of posterior joint node bevels were smaller.The condyles were shorter,thinner and tipped more anteriorly.The position of the conyles were more anteriorly.Conclusion:Class II skeletal type adult females with high vertical skeletal patterns have different forms of fossae,different positions and forms of condyle compared with the normal controls.
