Abstract
Generating a crown model using a statistical method (such as k-means clustering, principal component analysis (PCA), or similar statistical methods) can result in a crown model that is missing sharpness details below the threshold of the statistical technique. A method is provided to add back the sharpness to the resulting model by combining a single full-featured example into the algorithms generating the statistical model. The end result is a crown model that is relatively simple to produce and manipulate in real time, yet maintains the anatomical sharpness of a natural tooth.
