【摘要】 多生牙是临床常见的牙齿数目异常，可发生在颌骨的任何位置，埋伏多生牙可导致邻牙移位、牙根吸收、颌骨囊肿，常需手术拔除。传统方法拔除埋伏多生牙时需大量去骨，导致骨组织大量丢失，手术创伤大。本文报道超声骨刀“掀盖法”拔除左下后牙区埋伏多生牙伴囊肿1例。更多还原

【Abstract】 Supernumerary teeth are common clinical anomalies in the number of teeth, which can occur in any position of the jaw. Impacted supernumerary teeth can lead to displacement of neighboring teeth, root resorption, and cysts in jaw, which often need to be extracted. The traditional method of extracting impacted supernumerary teeth requires a large amount of bone removal, resulting in a large amount of bone tissue loss and surgical trauma. In this paper, we report the extraction of an impacted supernumerary tooth with cyst in left mandible by "bone lid technique" through piezosurgery.更多还原
