Abstract

Building the form of dental arch is of great importance for orthodontic diagnosis and treatment. This paper presents a novel automated method for detecting the arch curve from dental triangular meshes with minimal user intervention. The feature region between gingiva and teeth were firstly extracted based on discrete curvature analysis. Then using the feature region as reference, a feature image were generated where the arch skeleton is detected. The arch curve were finally computed to approximate the skeleton line based on B-spline extended fitting. The experiment results demonstrate that the method is fast and robust even in the presence of malocclusion.
