PHOTOGRAMMETRIC TECHNIQUES FOR DENTISTRY ANALYSIS, PLANNING AND VISUALISATION
Dentistry is a field which has a need for accurate information about teeth shape, their relative position and their appearance in the face. This information is essentially important for various dentistry fields such as orthodontia, teeth treatment, denture production. Existing methods for analyzing mutual teeth arches position (occlusion) use plaster teeth arches casts and a special mechanical tools which allow registering occlusion. For investigation and visualization of exterior appearance of teeth arches only 2D images are used which do not provide full and adequate presentation. So existing means do not give required accuracy and are not convenient for a dentist. Photogrammetric approach gives solution for all described problems with appropriate accuracy of measurements and high quality data for investigation, documentation and presentation. A set of new techniques for teeth occlusion registration and analysis is proposed based on applying teeth arch 3D model instead of a plaster mould. The developed photogrammetric techniques are used for automated patient face and teeth arch 3D models generation, for occlusion registration, treatment planning and documenting.
