Orthodontic Intrusion of over Erupted Permanent Maxillary Molars Using Temporary Anchorage Devices

摘要

In most cases, damaged mandibular molars result in over eruption of the opposing maxillary molars. This by itself constitutes a complicated clinical scenario;since the rehabilitation of the edentulous mandibular space usually requires a pre-prosthetic intervention. Multiple treatment options are valid and the choice depends primarily on the severity of the problem. Orthodontic molar intrusion is one of these options. This case report shows how the supra erupted maxillary permanent molars were intruded with the help of temporary anchorage devices placed interradicularly between the maxillary posterior teeth. A total of nine months was enough to complete the treatment. Following the orthodontic molar intrusion, the lower edentulous spaces were restored with dental implant supported prosthesis in order to establish a stable functional occlusion.
