title: A systematic modification of edgewise therapy.
abstract: This article describes a highly systematic modifcation of the edgewise technique that incorporates the principle of light continuous force application. It is a re-evaluation of our earlier article in view of the experience gained in applying this treatment approach in a teaching clinic. The classification of cases according to retraction requirements, the appliance designs, and the use of four basic phases of treatment remains largely the same as previously described. Some of the variations and modifications that have been necessary because of new information and pedogogical considerations are discussed. The treatment of typical orthodontic problems with differing retraction requirements is illustrated.
