Mini-implants are increasingly used for orthodontic anchorage. Using a mini-implant as anchorage in uprighting a mandibular molar, the need for other orthodontic appliances is minimal. Furthermore, the treatment is nog evoking any risk of disturbing the occlusion, since other teeth are not loaded. Depending on a good control of the applied forces and the extrusion of the molar during uprighting, the orthodontic treatment can be simple and not burdening the patient.
