REVIEW OF INTENSITY-BASED AND GEOMETRY-BASED REGISTRATION TECHNIQUES, APPLIED ON 3D CONE-BEAM CT DATA

M simulators have been helping to teach therapeutic and diagnostic procedures as well as the representation of medical concepts and in the process of decision of health professionals.Use of jaw motion simulators in dentistry, education, orthodontic adjustment of occlusions, or in the pre-operative planning of craniofacial surgery can be extremely useful, improving diagnosis and postoperative treatment. This article presents TMJsim, a simulator of mandibular motion constructed from real data coming from Computed Tomography and Magnetic Resonance images. A virtual joint model which composes the simulator receives points captured from the lower incisor point motion. Contribution of each muscle in temporomandibular movement is approached from the Hill actuators model and the concept of curves of insertion. Virtual Articulator is replacing mechanical articulators currently used with many advantages: more accurate simulation of motion, inclusion of new parameters such as muscle strength and it shows graphics for motion curve analysis.
