A Protractor is an orthodontic device used for treating the maxillary retrusion. It utilized the orthopedic force created by the pulling of the maxilla and counterforce of the mandibula.
Combination Anchorage Technique is a combination technique that consists of the Begg and the straight wire techniques. By using a special bracket and buccal tube, it is possible to maximize the benefits of both techniques in orthodontic treatment.
