Abstract:


With the elevated awareness of oral health and improved standard of living, there is an increasing demand for orthodontic treatment. Indeed, malocclusion (e.g. overjet and crowding) is a prevalent health issue because it compromises masticatory function (i.e. chewing) and causes aesthetic concerns. However, the traditional orthodontic treatment is costly, inefficient and of varied quality because the treatment process entails tedious manual operation and the treatment outcome heavily depends on the skills of individual orthodontists. All this calls for advances in digital orthodontics to make orthodontic treatment reliable, efficient, affordable and accessible.


Several imaging and computational technologies are already applied in digital orthodontics, ranging from image acquisition, tooth segmentation, visualization, CAD/CAM and 3D fabrication of customized appliances. In this talk I shall discuss how machine learning can be used to facilitate several key tasks in digital orthodontics. Specifically, some novel methods based on machine learning will be presented for solving the following key problems: (1) detection of cephalometric landmarks for diagnosis; (2) segmentation of teeth in 2D intra-oral scans and 3D cone-beam CT images; (3) determination of the optimal tooth setup to define the treatment goal; and (4) generation of tooth motion from the initial pre-treatment arrangement to the target setup for treatment simulation.
