Analysis of the Failure Mode of Dental Burs Due to Tear and Wear

The topic of the paper falls within the new research directions regarding the wear of dental burs, addressing the concept of their durability and reliability. Considering the operating life of dental burs and the conditions imposed by the environment, a series of elements that underlie the occurrence of the wear phenomenon are highlighted. The paper synthesizes the issues of degradation mechanisms and the effects they have on the active part of dental burs, on dental materials used in dental laboratories. The theoretical aspects, state of stresses and strains, their functional parameters in the work processes were identified, and one of the ways of evaluating the tear and wear of the active part of dental burs.
