The development of a pathological process may occasionally produce unexpected tooth movements, resulting in undesirable effects upon the occlusion. A 14-year-old Caucasian male patient is reported where a mandibular second permanent molar was extruded and tilted by a rapidly developing odontogenic keratocyst, which became evident 1 year after commencing orthodontic fixed appliance therapy. The rapidity of onset, the mode of presentation, and the effects upon the occlusion are discussed.
病理过程的发展偶尔可能会导致意外的牙齿移动，从而对咬合产生不良影响。本文报告了一名14岁的白种男性患者，其下颌第二恒磨牙因快速发展的牙源性角化囊肿而发生伸长和倾斜，这一情况在开始正畸固定矫治器治疗1年后变得明显。文中讨论了其发病的快速性、表现方式以及对咬合的影响。
