Non-extraction treatment of Class II malocclusion frequently requires upper molar distalization into a final Class I relationship. To achieve this, a variety of treatment modalities have been suggested. In order to achieve the appropriate system for the patient, it is essential to know the skeletal and dentoalveolar effects and the force system of each molar distalization mechanic. Succesful molar distalization results are obtained with extraoral or intraoral appliances for the correction of Class II molar relationship or for the creation of space in the upper arch. However, with the extraoral appliances, patient compliance arises as a major problem for both the patient and the orthodontist. Recently, several different intraoral procedures have been introduced to minimize the need for patient co-operation. The purpose of this review was to evaluate and compare the treatment effects of an extraoral appliance and an intraoral appliance for distal movement of maxillary first molars
