A system and computer-implemented method including generating a patient digital tooth model including a crown component; generating landmarks on an edge of the crown component; and generating a generic digital tooth model corresponding to the patient digital tooth model. The generic digital tooth model including both root and crown components. The method also includes mapping the landmarks on the edge of the crown component on to the generic digital tooth model; solving a first morphing function to fix landmarks on an edge of the crown component to a ring-edge space; solving a second morphing function to fix landmarks on the generic digital tooth model to ring-edge space; and selecting vertices in ring-edge space to stitch tooth crown with morphed template root.
