METHOD FOR MANUFACTURING ROOT CANAL FILLING TIP, AND ROOT CANAL FILLING TIP

摘要

Disclosed are a method for manufacturing a root canal filling tip, and a root canal filling tip manufactured by means of the method. The method comprises the following steps: step 1, selecting a medical vanadium-free nickel-free titanium alloy wire as a raw material; step 2, machining a first end of the vanadium-free nickel-free titanium alloy wire into a cone to form a closed section (1); step 3, machining a thick end of the closed section on the vanadium-free nickel-free titanium alloy wire to form a filling section (2); step 4, cutting one end of the filling section on the vanadium-free nickel-free titanium alloy wire into a plurality of scale lines to form a depth measuring section (31); and step 5, manufacturing a mould with a mould cavity, accommodating the filling section in the center of the mould cavity of the mould, and injecting heated gutta-percha (4) into the mould cavity to enable the gutta-percha to uniformly wrap the periphery of the filling section.
