Abstract

In this paper, we present an interactive system to adjust and animate 3D orthodontic treatment objectives, the main goal is to improve the communication tools used by orthodontists to exchange with their patients. Given a 3D pathological patient model and a treatment objective, we propose to automatically generate intermediate steps using script-like treatment scenarios. The intermediate steps can then be adjusted using intuitive manipulators, and used to produce an animation of the treatment. The resulting animation is a useful tool to help patients visualize the potential evolution of their dentition and accept the treatment. The proposed system relies on the registration of a reference model on both the treatment objective and the patient-specific 3D segmented mesh, to automatically position key feature points and create control curves. These primitives are used to both, guide teeth movements during the animation, and provide manipulators to allow for user interactions. The key contributions of this work are (a) the use of a registered reference model to position and create intuitive control primitives, and (b) the introduction of script-like treatment scenarios to facilitate and minimize user interactions during the creation of intermediate treatment steps.
