En-Masse traction with orthodontic implants


In modern orthodontics, Multi Bracket Appliance (MBA) is the most effective appliance to control the teeth in three-dimensions, especially with orthodontic implants. The orthodontic implants provide the skeletal anchorage, which allows the MBA to distalize or intrude the posterior molar predictably. Since there is a play between the bracket and wire in the MBA, in a strict sense, the movement pattern of each tooth is tipping. For the distlization of the posterior molar, the tipping movement is the fundamental issue of the MBA. Tipping could cause stress concentrations in the periodontal ligament, steps of the marginal ridges between adjacent tooth, and a stuck wire in the bracket slot by the distortion. To achieve an efficient tooth movement and eliminate the side steps during an active orthodontic treatment, I adopt a new approach as an alternative to the MBA. Lateral teeth from the first premolar to the second molar are fixed to the lingual arch with the bonding resin material. The lingual arch is pulled toward the orthodontic implants to achieve the En-masse traction of the lateral teeth in the manner of molar distalization or intrusion. In this presentation, I will outline the treatment outcome.
