1. To develop a prototype of iRadiate3D (including the 3Dprinted jaw and the AR application)

2. To develop practice exercises for intraoral radiography positioning using iRadiate3D with an emphasis on relating the spatial position of the film/holder to the final image.

3. To investigate whether iRadiate3D (specifically the impact of the opportunity for dynamic and real-time visualization)improves students’ ability to spatially relate the physical positioning of intraoral radiographic film/holder to the final radiographic image produced.

4. To understand how this elaborative rehearsal process aids in the students’ thought process in developing a rationale for their answers.
