A mandibular third molar moved into the lower border during a period of several years. When the patient experienced discomfort, an incisional biopsy and marsupialization were performed. Eight months later, adequate bone had regenerated and the molar and remaining cyst structure were removed. Full-mouth and panoramic radiographs would have allowed the dentist to locate the missing molar before surgery was necessary.
一颗下颌第三磨牙在数年时间里移至下颌骨下缘。当患者感到不适时，进行了切开活检和袋形术。八个月后，有足够的骨质再生，然后拔除了该磨牙并切除了剩余的囊肿结构。术前进行全口和全景X线片检查本可使牙医找到缺失的磨牙。
