EXPERIMENTAL SUBSTANTIATION OF THE CHOICE OF THE RESTORATION METHOD IN THE CERVICAL AREA OF TEETH WITH ABFRACTION DEFECTS

The etiology of abfraction defects is still in dispute. The etiology of these affections is not fully established. An important factor in the success of the treatment of abfraction defects of teeth by aesthetic restoration is the optimal choice of filling materials. It is impossible to improve the efficiency and quality of dental care without materials science. The aim of the study was to determine the strength of the restoration with uniaxial compression of the tooth before and after thermal cycling. The object of the study was 20 removed teeth with abfraction defects. The teeth were divided into two groups depending on the type of restoration. Half of the teeth were subjected to uniaxial loading in each group, the second half was subjected to thermal cycling before loading. Samples with indirect restorations showed greater strength both before and after thermal cycling
