METHOD OF CREATING THREE-DIMENSIONAL DESIGN PROJECT OF MARGINAL PARODONTIUM Russian patent published in 2014 - IPC A61C9/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to dentistry and is intended for diagnostics of esthetic impairment of marginal parodontium and dentitions. Parameters of biological zone of examined area are measured by Kois method in important zones and fixed in formalised map. Digital photography of marginal parodontium is performed in different projections, with preliminary application of two coordinate points at known distance on mucous membrane with thin contrast marker. Photographs are generated on resource of Autodest corporation by means of Autodesk 123DCatch software. After calculation of model and sending three-dimensional model of marginal parodontium by server in programme Autodesk 3dsMAX marking of parameters of individual's biological zone is performed. Distortion of image is taken into account by measurement of distance between applied coordinate points. Versions of design projects of marginal parodontium are created by correcting three-dimensional model in accordance with principles of existence of biological width and patient's esthetic demands. Simplicity of method application, minimal economic costs and invasive manipulations, maximal information about patient's esthetic status make it possible to widely apply the invention in everyday clinical practice of dentist.

EFFECT: method makes it possible to carry out quality planning of patient's esthetic rehabilitation.
