Abstract
Computer-implemented methods and systems for modeling teeth. Methods include generating a clinical crown mesh including visible surfaces of a clinical crown of a tooth; generating a parametric tooth model representing an average of multiple etalon teeth of the same tooth type; fitting the clinical crown mesh with the parametric tooth model to create an interim tooth model; and morphing the interim tooth model to mimic an anatomical shape of the clinical crown mesh. Fitting the clinical crown mesh with the parametric tooth model includes coupling point pairs on surfaces of the clinical crown mesh and the parametric tooth model, where a weighting factor is assigned to each point of the clinical crown mesh or parametric tooth model, and transforming the point pairs according to their weighting factors to cause the point pairs to converge.
