Abstract

Using additional equipment allows you to get information about the patients’ problems to plan the subsequent functional treatment. One of the important components that need to consider in the prosthodontic treatment planning is the individual trajectory of lower jaw movement. To register lower jaw articulation we use a new optical axiograph Dentograf, allowing obtaining the necessary data for programming mechanical and virtual articulator. This device may use in patients with any pathology of occlusion. The use of mechanical articulator allows producing prosthodontic constructions according to the individual protrusion and laterotrusion movements. In our study, we tried to reproduce additional, previously not used movements using plaster models of jaws: chewing, mouth opening. As a result, we have significantly upgraded the classical structure of the mechanical articulator. Our researches and using of additional devices formed the basis for articulation concept FIRA, which consists in the study and analysis of individual trajectories of lower jaw movement and implementing the data in the subsequent treatment. To minimize errors in the planning of functional treatment we have tried to eliminate unnecessary digital recounts of joint trajectories for obtaining numerical values of angles for programming the mechanical articulator.
