    Abstract:
    Overeruption of mandibular molars due to the loss of antagonist teeth causes occlusal functional disturbances. To restore proper occlusion, intrusion of the overerupted molars becomes essential before multidisciplinary reconstructive dental approaches can be initiated. Treatment protocols involving prosthodontic reduction, surgical impaction, and conventional orthodontic intrusion have been introduced. Orthodontic intrusion seems to be a favourable procedure which requires calibrated anchorage support. This case illustrates the management of a complex dental and functional problem with an interdisciplinary approach through the use of orthodontic, periodontal, restorative and implant therapy. In order to intrude the overerupted molar, a partial orthodontic appliance was used in conjunction with mini-implants and mini-screws. The results showed that the biological responses of the teeth and the surrounding bony structures to the intrusion appeared normal and acceptable. Periodontal health and vitality of the teeth were maintained throughout the treatment and even after one-year follow-up.
