METHOD FOR DETECTING TOOTH LOOSENING Russian patent published in 2015 - IPC A61C19/04 

FIELD: medicine.

SUBSTANCE: method involves an impression procedure and making a dental model, in which a route of insertion of a future tray and a centre of the vestibular surface of the examined teeth is marked with a chemical pencil. The dental model is compressed with heated base plate wax 2 mm thick. A melting hot plate is used to cut down the wax from a base of the model with leaving the same on the teeth only. The prepared composition is reproduced in a silicone mass. The silicone copy is filled with plaster to produce a model. The produced model is used to make a tray of a rigid transparent plastic 4 mm thick. Through holes are created with a conical dental cutter having the parameters of a periotest probe through the transparent plastic which is guided by the marks in chemical pencil. Excessive plastic is cut off to the level of the transitory fold; the tray borders are smoothed. The tray is removed from the dental model, processed with disinfectants and mounted on the patient's denture. The periotest probe is fixed into the cone-shaped through holes of the tray at a distance of 2 mm. The measurements are taken with the use of the periotest with keeping the patient's medical records. That is followed by integrated treatment; thereafter, the repeated examinations of teeth loosening with the use of the existing tray at the various stages of treatment may be required.

EFFECT: method enables providing the high accuracy of periotestometry in the patients, matching the obtained results of teeth loosening in the course of treatment.
