3D Assessment of Mandibular Growth Based on Image Registration: A Feasibility Study in a Rabbit Model
Figure 4
Comparison between Implant-based registration (a) and registration followed by Procrustes analysis (b) in one test animal. Surface meshes of the mandible obtained at baseline (blue) and after eight weeks (grey) were made transparent and then superimposed. Scalar fields were used to assess morphological changes using a color-coded quantitative representation (color map): Red indicating bone outward/deposition, green indicating small or no changes and blue indicating inwards/resorption. Note the greater amount of remodelling changes occurring at the mandibular ramus revealed by the implant method as compared to the registration/Procrustes method.
