METHOD FOR DETERMINING PERIODONTIUM FAILURE DEGREE Russian patent published in 2005 - IPC

Abstract RU 2256404 C2

FIELD: medicine.

SUBSTANCE: method involves applying flexible dental cappa plates having built-in radiopaque net set congruently to gingiva contour when being manufactured, and radiopaque thread placed on dental pocket bottom around teeth under study. Mesh diameter is equal to 1 mm. Several dental pocket depth values are measured. Total failure scale in periodontium is determined from formula CP=(D1+D2+…+Dn)/(L1+L2+…+Ln)*100%, where CP is the periodontium destruction degree, D1,D2,…Dn mean depth of each bone pocket in mm, L1,L2,…Ln is the total length of tooth root in mm. CP value being below 20%, I degree periodontium failure is diagnosed. The value being from 20 to 50%, II degree periodontium failure is diagnosed. The value being higher than 50%, III degree periodontium failure is diagnosed.

EFFECT: high quality of diagnosis.
