齿科用抗菌根管锉

Abstract

This project belongs to the field of medical materials and instruments. Specifically, it is a functional root canal file with antibacterial and osteogenesis ability. Root canal file is one of the necessary medical instruments for dental root canal therapy. In order to solve the infection problem that leads to surgical failure in root canal therapy, a novel root canal file with antibacterial property was developed based on TRIZ theory. A multi-functional Mg based metal coating was fabricated on root canal file. During surgery, Mg coating fall off naturally and fund in root canal, thus infection was avoided and capacity of osteogenesis at periphery of root apex was improved. Therefore, surgical success rate increased and long-term stability of the teeth was hopefully reinforced.
