摘要
A method for manufacturing a non-superelastic rotary file comprising the steps of: providing a superelastic rotary file having an austenite finish temperature; and heating the superelastic rotary file to a temperature of at least about 300° C. for a time period of at least about 5 minutes to alter the austenite finish temperature thereby forming the non-superelastic rotary file; wherein the altered austenite finish temperature of the non-superelastic rotary file is greater than about 25° C.
