Objectives.
To build a 3D parametric model to detect shape and volume of dental roots, from a panoramic radiograph (PAN) of the patient.
Materials and Methods.
A PAN and a cone beam computed tomography (CBCT) of a patient were acquired.
For each tooth, various parameters were considered (coronal and root lengths and widths): these were measured from the CBCT and from the PAN.
Measures were compared to evaluate the accuracy level of PAN measurements.
By using a CAD software, parametric models of an incisor and of a molar were constructed employing B-spline curves and free-form surfaces.
PAN measures of teeth 2.1 and 3.6 were assigned to the parametric models; the same two teeth were segmented from CBCT.
The two models were superimposed to assess the accuracy of the parametric model.
Results.
PAN measures resulted to be accurate and comparable with all other measurements.
From model superimposition the maximum error resulted was 1.1 mm on the incisor crown and 2 mm on the molar furcation.
Conclusion.
This study shows that it is possible to build a 3D parametric model starting from 2D information with a clinically valid accuracy level.
This can ultimately lead to a crown-root movement simulation.
