Prior to the replacement of a missing tooth with an implant the adult dentition, orthodontic treatment can be carried out to widen the space mesio-distally, correct the axial inclination of the neighbouring teeth and safeguard the anterior overbite. Implantation is not possible if, as a result of orthodontic treatment the gap cannot be widened to a minimum of at least 6 mm, if the alveolar bone is not thick enough in the vertical dimension or if the implant does not have sufficient space in the oro-vestibular direction.
在使用种植体替代缺失牙之前，对于成人牙列，可以进行正畸治疗以在近远中方向上扩大间隙、矫正相邻牙齿的轴向倾斜并维护前牙覆合。如果由于正畸治疗间隙无法扩大到至少6毫米的最小宽度、牙槽骨在垂直维度上不够厚或者种植体在口腔前庭方向上没有足够的空间，则无法进行种植。
