Abstract:
BACKGROUND: Orthodontic purposes, such as the prevention of anterior crowding, are common and controversial indications for surgical removal of the third molar (M3) germ in young patients. A higher tooth bud position and the risk of tooth displacement in the infratemporal fossa when surgery of the maxillary M3 germ is planned makes the success of germectomy unlikely with little benefit. A rare complication of maxillary M3 germ surgery is partial tooth building after germectomy.
METHODS: We report the case of a 14-year-old patient who was referred for germectomy of the maxillary M3 in the early development germ stadium to address space constraints and obstruction to the eruption of the second molar (M2) teeth. Computed tomography (CT) examination was used to verify the position and development of the maxillary M3 germ. The surgical procedure was performed without any complications. Eight years after the surgery, the patient presented with indefinable pain in the right upper jaw in the germectomy area. Cone-beam CT revealed a partial tooth formation in the form of a radix relict in the region of the maxillary M3.
CONCLUSIONS: The ongoing debate surrounding germectomy revolves around its indications and timing, considering factors such as patient age, anatomical appearance, and root formation stage. Complications, like partial tooth formation postgermectomy, highlight the importance of precise timing in treatment.
CONCLUSIONS: This is the first report of partial tooth formation as a complication after germectomy of the M3 germ in a complete crown-formation stadium.
摘要:
背景:正畸的目的,例如预防前路拥挤,是年轻患者手术切除第三磨牙(M3)细菌的常见且有争议的适应症。计划进行上颌M3胚芽手术时,较高的牙芽位置和颞下窝牙齿移位的风险使成功的胚芽切除术不太可能带来益处。上颌M3胚芽手术的罕见并发症是胚芽切除术后的部分牙齿形成。
方法:我们报告了一例14岁的患者,该患者在早期发育的胚芽体育场接受上颌M3的胚芽切除术,以解决空间限制和第二磨牙(M2)萌出的障碍。计算机断层扫描(CT)检查用于验证上颌M3胚芽的位置和发育。手术操作无任何并发症。手术八年后,患者在生殖道切除区域的右上颌出现了无法确定的疼痛。锥形束CT显示,在上颌骨M3的区域中,部分牙齿形成为基数状。
结论:围绕生殖器官切除术的争论围绕其适应症和时机展开,考虑到患者年龄等因素,解剖外观,和根形成阶段。并发症,像部分牙齿形成后,强调治疗中精确时机的重要性。
结论:这是在完整的牙冠形成体育场中,对M3胚芽进行胚芽切除术后,部分牙齿形成作为并发症的第一份报告。
