NURBS-based Reverse Engineering of the Mandible, Creation of a Layered 3D Model Based on Real CT Scans

Abstract

This paper presents the high-resolution reconstruction of a human mandible and lower dentition based on real CT data. The primary goal was to create a continuous spline-based computer model that provides a robust foundation for analyzing the tooth–bone interface. Special emphasis was placed on the realistic integration of teeth into the mandible, enabling the model to be divided into distinct biological layers. The resulting geometry is fully prepared for numerical simulations, where individual solid parts can be assigned specific material properties, allowing more accurate finite element analysis of the mechanical behavior of different regions.
