METHOD OF RESTORATION AND REINFORCEMENT OF TEETH WITH SIGNIFICANT DESTRUCTION OF THE CROWN OF THE TOOTH

Abstract

Background: One of the ways to improve the quality of restoration of the crown part of the tooth is to add a reinforcing component that increases the strength and durability of the restoration.
 Aim:Propose a new method for restoring extensive defects in hard tissues of teeth with additional reinforcement
 Materials and methods: In the course of the work, 100 chewing anatomical and functional teeth removed according to various indications were used. Carious cavities of all teeth after removal were prepared for class 1 G.V. Blаck cavities. The wall thickness was measured using a dental micrometer, the wall thickness of half of the teeth (40) was more than 3 mm, half (60) - less than 3 mm, on the basis of which it was calculated how the load would be distributed in the tooth, based on this, the optimal installation method was determined threads with composite in the tooth cavity. We used: dental adhesive Single Bond Universal in separate packages, dental composite material 3M ESPE Filtek Ultimate Universal Restorative, thread with composite material (light-curing dental fiber formed CATERPILLAR), also during the work we used a dental micrometer, laboratory electrical equipment: testing machine, hardness tester, Shimadzu trademark, LEDEX dental light curing lamp, model WL-070, Carl Zeiss Primo Star laboratory microscope, emission scanning electron microscope Merlin (Zeiss).
 Conclusion:The "Method of restoration of molars in case of significant destruction of the crown part of the tooth" has been developed (RF Patent No. 2783060). It is proposed as a method of restoration of extensive defects of the crown part of the tooth using a composite tape as a reinforcing component. When analyzing the results of the study on the Shimadzu bursting machine, it was revealed that restorations carried out using a composite thread are more durable and, accordingly, durable than similar therapeutic restorations of the shape and function of the tooth carried out without using a composite thread.
 Results: In a laboratory test for maximum compression and stress, teeth restored using a combination of floss with composite and composite material have shown significantly greater resistance than teeth restored with composite material alone.
