ARTIFICIAL FOOD BOLUS AND METHOD FOR INSTANT ASSESSMENT OF DENTO-FACIAL HEALTH WITH USING ARTIFICIAL FOOD BOLUS

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, particularly to dentistry, and aims at the instant assessment of a patient's adaption to dental structures. There are used two identical artificial food boluses unbreakable by chewing and presented as a cylinder of the diameter of 1 cm ending with hemispheres 4 cm long; a plaiting thread is attached to one of the boluses; the thread has a pin on the other side to be fixed on the patient's clothes when chewing. An elastic base of the bolus is porous neoprene having a porosity of no more than 30% and air-filled. Before use, the artificial food boluses are heated to a temperature of +37°C. Heat emission of the patient's oral cavity tissues is controlled by means of a thermal camera. The bolus thread pin is fixed to the patient's clothes, and the patient is asked to place the bolus into the mouth and chew it for 30 sec, with the bolus advanced sequentially along the whole dentition. That is followed by analysing the heat emission dynamics of the oral cavity tissues. If observing no hyperthermia or short-term uniform or symmetrical temperature increase in the oral cavity tissues, the patient's adaption to chewing is considered to be high and his/her dental structure is stated to be highly stable. The non-uniform, asymmetrical and long-term tissue temperature increase shows the patient's low adaptation to chewing, low stability of his/her dental structure is predicted. The dental structure is mounted with controlling the tissue heat emission dynamics after 30-second chewing of the artificial food bolus heated to +37°C and identical to the first one; the heat emission dynamics is compared to the initial one; and an increase of the hyperthermia and its length shows the low patient's adaptation to the dental structure, and the tissue injuries are predicted.;EFFECT: by the instant assessment of the patient's adaptation to the dental structures, the method enables preventing food chewing complications following mounting the dental structure with the patient's low stability to chewing.;2 cl, 1 ex
