Wireless Dental Probe for Orthodontic Treatments
University of Louisville This project will create a 3D surface model of the human jaw from optical imaging. The instrumentation system for generating the model will be simple and inexpensive. Using a small-size CCD camera fitted with a magnetic tracker, a sequence of calibrated 2D images is generated which spans the jaw. Geometrical computer vision methodologies are employed to extract 3D information from the sequence of images, which are then registered together to construct the jaw. Characteristics of the jaw are exploited in the registration. The 3D surface model is in itself very useful for basic studies of tooth alignments and in a number of orthodontic practices. Additional texture information about the gum will be registered to the 3D model, creating a realistic model of the inter-oral cavity.The outcome of this project is a dental probe formed of CCD sensor, tracker, and software system for image capturing and 3D model building. The probe will be fitted with communication and file transfer mechanisms. This technology will be beneficial for various dental applications, and will lend benefit to other applications of object scanning
