Abstract: Angle class Ⅱ malocclusion is the most common dental malformation in clinical practice. Different types of malocclusion also affect the shape and position characteristics of the condyle. After orthodontic treatment，malocclusion patients will have their occlusion changed，and the shape and position of the condyle will undergo adaptive reconstruction to further maintain the stability and balance of the oral and maxillofacial functional system. This article summarizes the features of shape and position of the condyle in patients with Angle class Ⅱ malocclusion before and after orthodontic treatment.

Key words: malocclusion, Angle class Ⅱ, condyle shape, condyle position
