    【Abstract 】 AIM: To create a digitized threedimensional (3D) model of skull by using Broadbentbolton lateral and frontal biorthogonal radiographic planes. METHODS: 3D landmarks were located from the conventional lateral and posteroanterior cephalograms and 3D model was fitted by using BSpline curve. RESULTS: Model of 3Dsurface of skull was made by BSpline curve. CONCLUSION: Rebuilding the 3D surface of skull lays the basis for 3D measurement and analysis.
