Abstract

This clinical case report describes a case of bilateral partial edentulism in the posterior mandible with skeletal mandibular protrusion. The patient was a 43-year-old woman with the chief complaint of masticatory and cosmetic disturbance. In this case, dental implants were used to anchor non-surgical orthodontics. Three dental implants were placed in the posterior mandible, then orthodontic treatment was carried out using these dental implants as orthodontic anchors. In addition, orthodontic mini-screws were placed for vertical intrusion of lower anterior teeth. After correction of reversed occlusion of anterior teeth and extrusive upper and lower teeth, the final implant-supported superstructure was inserted. Implant prostheses and oral hygiene were maintained in excellent condition during 3 years of follow-up.
