This paper analyzes two different navigation approaches: a computerized tomography (CT) marker based approach and a conventional non-computerized tomography marker approach. This study provides advantages and benefits of the CT marker based approach. 3D coordinates, frame description, homogeneous transform, and kinematic equations are calculated and displayed in a GUI. Results show that the CT maker based approach are not statistically different from conventional approaches and thus viable to perform intelligent dental navigation. © 2008 IEEE.Mahidol UniversityComputer ScienceConference PaperSCOPUS10.1109/CSIE.2009.976
