System and method for three-dimensional complete tooth modeling

A computer-implemented method comprising:

• receiving at least one patient digital tooth model comprising a patient crown component and at least one generic digital tooth model comprising a root component and a crown component, the generic crown component corresponding to the patient crown component;
• and
• morphing the at least one patient digital tooth model with the at least one generic digital tooth model to provide a complete digital tooth model of the patient, wherein morphing comprises:
• utilizing crown landmarks to generate a first morphing function to determine a morphed central axis;
• repositioning a central axis of the generic tooth model to be tangent to the morphed central axis;
• scaling the repositioned central axis of the generic tooth model to be equal to the morphed central axis in a particular direction;
• and
• utilizing the crown landmarks from the patient digital tooth model and root landmarks from the generic digital tooth model to generate a second morphing function;
• calculating a patient root component from the second morphing function;
• stitching a corresponding patient crown component to the patient root component;
• and
• conducting interactive adjustment of the patient root component by adjusting by at least one of length and rotation.
