Orthodontic implant site-switching technique

The orthodontic implant site-switching technique uses orthodontic tooth movement to augment the deficient alveolar bone in preparation for implant placement while obviating or reducing the need for bone grafting.

Background

All techniques of augmenting the alveolar bone in preparation for implant placement are invasive and associated with a degree of morbidity;[1] However, the literature provides evidence that orthodontic tooth movement can generate new bone.[2] This is because of the fibres of the periodontal ligament (PDL) surrounding the teeth and attached to the alveolar bone, the stretched fibres in the PDL stimulate the osteoblasts depositing new alveolar bone. For instance, the orthodontic forced eruption of hopeless teeth can augment the bone vertically and eliminate or reduce the amount of bone graft required prior to implant placement.[3]

Similarly, where there is a bone-deficient edentulous site, it is possible to move the healthy adjacent teeth into this area, closing the edentulous space and simultaneously creating an implant site with enough bone adjacent to where implant placement was originally planned.[4][5][6]
