Maxillary central incisors have the least incidence of congenital absence. When it does happen, the patient may present with over retained deciduous centrals or the contralateral central may have drifted into the available space presenting as generalised anterior spacing with loss of midline. In such cases a multi-disciplinary approach may be required with orthodontic treatment to re-organise the space available in order to rehabilitate the patient with a fixed prosthesis. This case report presents the treatment of a patient with congenitally missing maxillary left central incisor using dental implant with angulated abutment after orthodontic correction and stabilization of the remaining maxillary anteriors.
上颌中切牙先天性缺失的发生率最低。当这种情况发生时,患者可能会出现乳牙滞留,或者对侧中切牙可能会向缺牙间隙移位,导致前牙区普遍出现间隙并伴有中线丧失。在这种情况下,可能需要采取多学科治疗方法,通过正畸治疗重新调整可用间隙,以便为患者安装固定修复体进行修复。本病例报告介绍了一名上颌左侧中切牙先天性缺失患者的治疗过程,该患者在正畸矫正并稳定剩余上颌前牙后,使用带角度基台的牙种植体进行修复。
