A 3D dental model dataset with pre/post-orthodontic treatment for automatic tooth alignment

This is the first public 3D orthodontic dental dataset, comprising 1060 pairs of pre/post-treatment dental models sourced from 435 patients aged between 8 and 35 years old. The dataset encompasses raw dental models with diverse malocclusion, e.g., tooth crowding, deep overbite, and deep overjet; and comprehensive professional annotations, including tooth segmentation labels, tooth position information, and crown landmarks.
