Resumo
Durante o tratamento endodôntico buscamos o adequado preparo do canal radicular fazendo uso de instrumentos endodônticos, que são submetidos a diversas forças como torção, flexão e pressão, sendo exposto a falhas mecânicas, alterações na anatomia do canal ou a fratura do próprio instrumento. Com o propósito de aperfeiçoar o tratamento endodôntico evitando tais complicações, foram introduzidos diversos procedimentos em sua fabricação utilizando diferentes ligas metálicas incluindo o seu tratamento térmico, mecânico e de superfície visando obter melhores propriedades mecânicas como maior resistência a fratura e maior flexibilidade. Este trabalho de conclusão de curso tem como objetivo de revisar e discutir as vantagens do uso de instrumentos endodônticos com ligas tratadas na pratica clínica e sua eficácia.
During the endodontic treatment, we search for the proper preparation of the root canal using endodontic instruments, which are subjected to various forces such as torsion, flexion and pressure, being exposed to mechanical failures, changes in the anatomy of the canal or fracture of the instrument itself. In order to improve the endodontic treatment, avoiding such complications, several procedures were introduced in its manufacture using different metallic alloys, including its thermal, mechanical and surface treatment, aiming to obtain better mechanical properties such as greater fracture resistance and greater flexibility. This course conclusion work aims to review and discuss the advantages of using endodontic instruments with treated alloys in clinical practice and their effectiveness.
