Nitinol in dentistry

Abstract

An alloy of nickel and titanium In recent years, endodontic instruments have been made using nitinol. A lower modulus of elasticity and better strength are found in nitinol alloys when compared to stainless steel alloys. Because of their extremely elastic nature, Nitinol wires regain their original shape after deformation upon unloading. These qualities are interesting to endodontists because they make it possible to build root canal tools that take advantage of these advantageous traits to give them an advantage while creating curved canals. In order to fully understand the special qualities of nitinol alloys utilized in dentistry, this review attempts to give an overview of them.
