Motivations: Clinical Applications in Orthodontics

We are aiming to develop methods to compute Shape Correspondence and Shape Analysis to the Orthodontic Clinical field. The main challenge in this approach is the complexity of the surfaces processed, i.e. Cranio-Maxillo-Facial anatomy. Until now, Shape Correspondence was applied almost entirely to brain morphometry studies. SPHARM-PDM Toolbox has been used until now for different Ortho applications, however the performance of this methodological framework does not work satisfactorily for Full Mandibles. Our main interest focuses right now in Entropy-Based Particle Systems [1], that does not rely in parametric fields or spherical topology for establishing correspondence in a Surface Ensemble.

Project

Objectives

1. Integrate tools developed to be used with ShapeWorks particle-optimization shape correspondence program, developed by Utah U.
2. Slicer3 color map visualization
3. UNC SPHARM-PDM shape analysis module integration in Slicer3.
4. Application of Slicer3 for Cranio maxillo facial surgical planning, discussions about how Slicer3 clips, rotates, mirrors.
