        <Explanation>The American Association of Orthodontists provides sponsorships and similar funding to established programs and organizations. Annual contributions to the Graduate Orthodontics Residents Program (GORP) sponsor a 3 day event which introduces residents to the programs and services of the AAO and builds relationships between the various orthodontic programs and the students in them. The contribution is used to fund space rental for the meeting, meals and social events for attendees. In order to ensure that all orthodontic residents are able to benefit from the knowledge of educators who specialize in various aspects of orthodontics, the AAO supports the university distance learning program. The distance learning program uses advance technology to capture lectures, create an interactive learning experience and allow visual participation by orthodontic residents.</Explanation>
