Abstract
This paper proposes a simulation system for intraoral radiography. The simulator we have developed enables dental students or interns to practice intraoral radiography without X-ray radiation and film costs. A system user can quickly obtain an intraoral radiograph after setting an indicator cone and film with respect to the simple dental mannequin mounted on the system. In this paper, we develop a dental-shape database from multi-slice CT images of human teeth, and formulate an algorithm to output the image of the intraoral radiograph on a computer display, where the dental-shape data, three-dimensional positional data of the indicator cone and film are input. Realistic observations of actual intraoral radiography are simulated.
