FIELD: medicine; dentistry. ^ SUBSTANCE: method involves preliminarily improving worn-down chewer teeth occlusion, determining tooth color from VITA scale, making gingiva retraction, forming U-shaped groove on each tooth along cutting edge and on approximal surfaces and bearing areas on oral surface mating the tooth grooves along cutting edge. The oral surface is prepared on 1/3 of its length 1-2 mm far from medial and distal borders. Reinforcing rectangular gold-plated metal gauze is fixed on the supporting area. The gauze width is selected not to be greater than sum of tooth crown width and interdental space. The gauze is fixed at least 1 mm blow the cutting edge level. Its separated intermediate portion formed in advance in accordance with supporting area dimensions. When being fixed, the gauze is thrusted against supporting area. Gauze portions to be fixed in grooves on approximal surfaces are formed as free wires brought close to each other in pericervical zone before final substitution of diastemas and restoring cutting edges with hard tissue losses taken into account and composite materials being applied. ^ EFFECT: enhanced effectiveness of lower dentition treatment in worn hard tissue cases. ^ 2 cl |
