[Determination of regimes of functional loading in the patients with traumatic mandibular fractures after...

There are presented the modern possibilities of application of the computeric modeling methods, including CAD/CAM/CAE technologies, in the planning of osteosynthesis and determination of the functional loading regimes in the patients, suffering traumatic mandibular fracture. Virtual models of the systems "bone-fixator", created on the ground of analysis of the spiral CT and functional investigations data, have had demonstrated highly precisely the anatomic peculiarities of the patients chewing system, ununiform physicomechanical properties of the fractures bone tissues and conditions of functional loading while the teeth closure. Mathematical calculations, conducted on the models, have permitted to estimate the value and character of the local pressure and deformity, occurring in the system elements, and to estimate its rigidity and safety in conditions of the chewing load. The model calculations were taken in account while choosing the patients rehabilitation regimes in posttraumatic period. Clinical investigations, conducted in immediate and late follow-up periods after the operation, have confirmed the trustworthiness of the model calculations and possibility of the method application while decision making in complex, atypical clinical settings.
