Supernumerary tooth may closely resemble the teeth of the group to which it belongs, i.e. molars, premolars or anterior teeth, or it may bear little resemblance in size or shape to which it is associated. Many complications can be associated with supernumeraries, like impaction, delayed eruption or ectopic eruption of adjacent teeth, crowding, development of median diastema and eruption into floor of the nasal cavity. This may also cause the formation of follicular cysts with significant bone destruction. Early intervention to remove it is usually required to obtain reasonable alignment and occlusal relationship. This article will present the clinical management of an (i) impacted supernumerary tooth impeding the eruption of maxillary central incisor and (ii) erupted supernumerary tooth with midline diastema.
多生牙可能与它所属的牙组（即磨牙、前磨牙或前牙）非常相似，或者在大小或形状上与相关牙齿几乎没有相似之处。多生牙可能会引发许多并发症，如阻生、相邻牙齿萌出延迟或异位萌出、牙列拥挤、正中牙间隙形成以及萌入鼻腔底部。这也可能导致伴有明显骨质破坏的滤泡囊肿形成。通常需要早期干预将其拔除，以获得合理的牙列排齐和咬合关系。本文将介绍一例（i）阻生多生牙妨碍上颌中切牙萌出和（ii）已萌出的伴有中线牙间隙的多生牙的临床处理。
