Current methods to produce 3-dimensional tooth root models involve conversion from radiographic means (computed tomography) or creation using computer-assisted design (CAD) software. The former lacks detail while the second is manually fabricated and can bear little resemblance to the original. Thin-plate splines have been used in morphometries to define changes of shape between subjects of the same species . Herein, we use thin-plate splines to deform a 3D geometric prior model of a tooth to match 2D patient radiographs, producing a "best- fit" patient specific 3D geometric polygonal mesh of the tooth.
