Abstract

Orthodontic extrusion of canines, although challenging, can yield excellent results without tooth extraction. Temporary anchorage devices (TADs), involving mini-implants in the alveolar bone, offer stable anchorage via biomechanics. This case report details orthodontic extrusion of bilaterally impacted maxillary canines using TAD mini-implants and elastics. The patient had bimaxillary protrusion, moderate crowding, deep bite, and vertical growth pattern, necessitating careful treatment planning. The combination of TAD mini-implants with Class-II elastics simplified biomechanics. The treatment achieved efficient results, maintained adjacent teeth positioning, and improved patient compliance.

摘要

犬齿的正畸性萌出虽然具有挑战性,但在不拔牙的情况下也能取得优异的效果。临时锚固装置(TADs),即在牙槽骨中植入微型种植体,通过生物力学提供稳定的锚固。本病例报告详细介绍了使用TAD微型种植体和弹力牵引对双侧上颌埋伏阻生犬齿进行正畸性萌出的情况。该患者有双颌前突、中度拥挤、深覆合和垂直生长型,需要仔细的治疗计划。TAD微型种植体与II类弹力牵引的结合简化了生物力学。该治疗取得了有效的结果,保持了邻牙的位置,并提高了患者的依从性。
