CLOSE‐RANGE PHOTOGRAMMETRY APPLIED TO RESEARCH IN ORTHODONTICS

Research work is being undertaken by the Department of Orthodontics at Addenbrooke's Hospital, Cambridge, which involves studying the growth of children's faces in three dimensions. In evaluating the morphology of soft tissues, the advantages offered by photogrammetry have been recognised and this paper describes how the technique has been put into practice at the hospital where a stereometric instrument, equally suitable for use as a camera or as a projection plotter, has been constructed. Resume La Section Dentaire de l'Hopital Addenbrooke a Cambridge etudie la croissance dans les trois dimensions de la face enfantine. On a tout de suite reconnu les avantages que presente la photogrammetrie dans la morphologie des tissus mous. Cette communication decrit l'emploi & dcar;un appareil photogrammetrique, construit a l'hopital, qui serf aussi bien d'appareil photographique que de restituteur stereoscopique a projection optique.
