[Orthodontic extrusion preliminary to implantology in the -aesthetic zone].

The replacement of a missing tooth in the aesthetic zone by a dental implant is, in many respects, a challenge. In order to restore and maintain bone and soft tissue, various procedures are used varying from the immediate placement of a front tooth implant with minimal tissue grafts to an extensive treatment programme with bone grafting, possibly in combination with connective tissue grafts. Another treatment option is orthodontic extrusion. This procedure makes it possible for bone and soft tissue to be created both horizontally and vertically, as a result of which loss of vertical binding can be compensated and the primary stability of the implant can be guaranteed. The procedure for orthodontic extrusion is described on the basis of a case study. In an interdisciplinary treatment plan, orthodontic extrusion is a viable treatment alternative, which can make the immediate placement of a dental implant in the frontal region possible.
