Skeletally based miniplate supported orthodontic anchorage

Abstract

m m fi fl z s M t o t p i a t T a c o m rthodontic treatment is often limited by the severity f malocclusion and biomechanical restrictions of vailable appliances. Many devices and techniques ave been developed over decades to assist or augent orthodontic anchorage. Headgear, Pendulum nd Herbst appliances, magnets, and elastics, alone nd in combination, are examples of the many opions available to the orthodontist to control the ovement of teeth. All of these purely orthodontic echniques have practical limitations related to paient compliance, reliance on tooth or soft tissue upport, or the complex nature of the malocclusion o be treated. Adjunctive surgery is often required to chieve acceptable results. The concept of using implants for orthodontic anhorage has been studied for over 25 years. Tradiional endosseous implants placed in the alveolar one and used as orthodontic anchors have been xtensively reported. More recently, midpalatal ndosseous implants, miniscrews, and miniplates ave been used successfully for skeletal anchorage to orrect malocclusions that are difficult or impossible o treat with traditional orthodontic methods. Jenner and Fitzpatrick first reported the use of an steotomy plate for orthodontic anchorage in 1985. ore recently, investigators have used miniplates in he mandible and the maxilla to assist in correctng skeletal open bite deformities in adult patients ho would normally require orthognathic surgery. iniplates for orthodontic anchorage have also been emonstrated in patients with supererupted posterior eeth and to distalize molars. Miniplate anchorage has been used with success or over 5 years at Nova Southeastern University to ssist in closing skeletal anterior open bite, intrude upererupted teeth, and as anchorage adjuncts for agittal tooth movement.
