| Abstract [eng] |
Relationships between muscle tensions, jaw motions, bite and joint forces, and craniofacial morphology are not fully understood, and critical information is often difficult or impossible to obtain in experiments on living humans. The inaccessibility of the mandible and its related structures is a major obstacle to measure their internal forces and stresses, and understanding their effects. Computer modeling offers an alternative method for doing this. Despite its limitations, modeling appears to provide a useful conceptual framework for developing hypotheses regarding the role of stresses during human masticatory system function. Three-dimensional model of main elements of masticatory system was created from computed tomography images. Later this model will be improved with physical characteristics. The objective of this work is to select the set of tools and create the new ones which could be used to acquire the three dimensional model from tomography images. The rules and restrictions of using medical hardware should be taken into account. The main outcome of this work is a macro-command created for the “Image Pro Plus”, which is used to capture object coordinates from the tomography pictures. Experiments were made to define the factors which are influencing the quality of the created model. |
