Manufacturing method of root canal filling tip

Abstract

The invention provides a manufacturing method of a root canal filling tip, and belongs to the field of medical equipment. The manufacturing method of the root canal filling tip comprises the following steps: step 1, selecting a medical vanadium-free nickel-free titanium alloy wire as a raw material; step 2, processing a first end of the vanadium-free nickel-free titanium alloy wire into a cone to form a closed section; step 3, processing a filling section from a thick end of the closed section on the vanadium-free nickel-free titanium alloy wire; step 4, cutting into a plurality of scale lines from one end of the filling section on the vanadium-free nickel-free titanium alloy wire to form a depth measuring section; and step 5, manufacturing a mould with a mould cavity, putting the filling section in the center of the mould cavity of the mould, and injecting heated gutta-percha into the mould cavity to enable the gutta-percha to uniformly wrap the periphery of the filling section. The root canal filling tip manufactured by the manufacturing method provided by the invention adopts the vanadium-free nickel-free titanium alloy wire as the raw material, has high biocompatibility and is safe to use; and the root canal filling tip adopts an integrally formed structure, avoids welding and prevents harmful substances in a welding flux from permeating a human body.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a method for manufacturing a root canal filling tip. Background technique [0002] The root canal is the structure of the oral cavity inside the tooth. There is a hollow structure in the middle of the tooth, called the pulp cavity, and the upper part of the pulp cavity structure is wide, called the pulp chamber, which contains soft tissues such as dental pulp; the lower part of the pulp cavity structure has a tubular root canal, that is, the root canal, from which the dental nerve and Blood vessels that nourish the nerves. [0003] Root canal therapy is the most commonly used effective treatment for pulp disease and periapical disease in the world. The principle of root canal therapy is to remove most of the infection in the root canal through mechanical and chemical methods, and to prevent the occurrence of periapical lesions or promote the healing of periapical lesions that h...
