The overall aim of this research is to apply the use of model-based computer vision methodology in order to develop a system for dentistry to go beyond traditional approaches in diagnosis, treatment planning, surgical simulation and prosthetic replacements. This computer vision methodology should obsolete the use and avoid the discomfort of the mold process used today as well as substantially improves the data accuracy available to the oral surgeon and dental care personnel. Our main objectives are as follows: (i) to design a flexible data acquisition system to capture high quality calibrated intra-oral images of the Jaw, Teeth, and Gums (ii) to develop methods for accurate 3-D reconstruction from the acquired sequence of intra-oral images using state-of-the-art approaches in 3D reconstruction, including shape from shading, and space carving techniques; (iii) to develop and automate a robust algorithm for fusion of data acquired with accurate and fast 3D data registration; (iv) to develop a specific object segmentation and recognition system to separate and recognize individual 3D tooth information for further analysis and simulations; (v) to develop algorithms to simulate tooth movement based on the finite element method and deformable model approaches; (vi) to develop a database software with a user friendly GUI interface which stores the acquired digital models in a database that can be retrieved on demand and shared over computer networks for further assistance in diagnosis and treatment planning; and (vii) to enable the use of haptic feedback interfaces on our 3D jaw models in future work.
