One of the unprecedented effects of using temporary anchorage devices (TADs) is to intrude posterior teeth and then to close the open bite. Posterior intrusion often decreases mandibular plane angle which leads to better chin projections in Class II malocclusion. For patients with degenerative temporomandibular joints, orthodontic treatment can benefit them for better chewing function after their joints have been stabilized . Treatment mechanics and outcome of conservative orthodontic treatment using TADs will be presented. Stability of using TADs or surgical orthodontics for closing these acquired open bites will be discussed.
Evaluate appropriate timing for treating these acquired open bites.
Adopt this treatment modality using TADs and apply appropriate mechanics to treat acquired open bite.
Address the stability issue to patients before treatment starts.
