FIELD: medicine, stomatology, orthodontics. SUBSTANCE: method deals with inspection of jaw models. Positions of teeth rows and jaw bones are transferred to the device by facial arc to estimate both position and rate for upper and lower teeth rows against total coordination point on occlusion plane and certain perpendicular, then stencil with teeth rows is applied onto model according to the norm values to determine deviations in teeth rows structure and their position against coordination point. Device for prediction of teeth rows anomalies contains upper and lower shelves with socles for teeth models, descriptive frame is well attached to lower shelf with a bar on rotating arms and fixation mechanism and coaxially installed dowels. EFFECT: higher efficiency and accuracy, decreased number of roentgenograms. |
