Abstract
Maxillofacial trauma are common, secondary to road traffic accident, sports injury, falls and require sophisticated radiological imaging to precisely diagnose. A direct surgical reconstruction is complex and require clinical expertise. Bio-modelling helps in reconstructing surface model from 2D contours. In this manuscript we have constructed the 3D surface using 2D Computerized Tomography (CT) scan contours. The fracture part of the cranial vault are reconstructed using GC1 rational cubic Ball curve with three free parameters, later the 2D contours are flipped into 3D with equidistant z component. The constructed surface is represented by contours blending interpolant. At the end of this manuscript a case report of parietal bone fracture is also illustrated by employing this method with a Graphical User Interface (GUI) illustration.
Highlights
Craniofacial region is a complex anatomical part made up of various bones joined together
Craniofacial fractures occurs due to various etiological factors like road traffic accident (RTA), sports injury falls etc
Since Digital Imaging and Communications in Medicine (DICOM) data used in our work are in 2D form, so, before constructing the 3D surface, firstly, we have constructed fracture part curves using geometric continuity (GC1) rational cubic Ball curves with three free parameters
Summary
Craniofacial region is a complex anatomical part made up of various bones joined together. Contours blending function have been used to construct the 3D parietal bone fracture.
