Abstract

The performances of endodontic instruments are improving with the advancement of them. This advancement is because of the composition and material of which the endodontic instruments are made. Today, there are made Ni Ti instruments, to improve the metallurgical properties and to have better elasticity and flexibility than classic stainless still endodontic instruments. In addition, rotary and reciproc instruments are especially important, beside manual endodontic instruments. In order to function successfully, they need to have adequate torque. Finite Element Analysis is used for stress access in different areas. Today, the FEA is widely used in dentistry to detect the torque generation of rotary instruments. FEA can simulate the torque distribution and is an engineering method for numerical analysis. There are, several computer software programs, that works with FEA and they have 3D views of relevant data for analysis. The benefits of FEA are: precise modeling of instruments with all the characteristic design details and precise modeling of the complicated geometry of the anatomical-morphological characteristic of the teeth, including the root with the canal system, as well as coronary morphological characteristics. FEA can be used to show pressure transfer, to see the places of load as well as the places of tooth fracture and shows the places of instruments fracture. FEA, also, provides the opportunity for setting the torque in rotary and reciproc endodontic instruments. Torque is one of the parameters that shows the generation of stress during root canal shaping. Several studies have shown tooth cracks due to NiTi instruments shaping, depending of different speed and torque setting. Therefore, every time, a new endodontic instrument enters the dental market, research using multiple fields is required. At the same time, it is necessary to include as much as possible all the ways of research to complete the picture, to get more information about the endodontic instrument and to get the clear understanding of the way of working.
