(1) filling plastic: taking a proper amount of denture powder, placing the denture powder in a clean container, gradually adding denture water according to the ratio of 24g of powder to 10ml of water until the denture powder is completely wet and is in a wet sand shape, after the plastic is well mixed, covering a vessel, waiting until the dough period, filling the denture powder into a dental crown male mold, adding a mold box cover, and placing the mold box cover in a squeezer to slightly press down so as to prevent the dental mold from being crushed to cause deformation;
(2) and (3) heat treatment: fixing the mould box on a mould box clamp, then placing the mould box in a room-temperature water pot, immersing the mould box in water, heating the mould box to a boiling point within 1.5-2.0 hours, maintaining the temperature for 15-30 minutes, and fully cooling the mould box at room temperature;
s6, opening a box and polishing: taking down the model box, slightly rotating the model box from the upper model box to the lower model box by a knife, knocking the bottom of the model box by a bolt hammer to remove the model, separating the false teeth by a plaster shear,
s7, grinding and polishing: grinding the false tooth to remove the excessive plastic on the edge of the base support, the undercut and the small tumor on the tissue surface, then evenly grinding the ground surface of the base support by using green sand stone or sand containing rubber, carefully grinding by using a small brush of a wet cloth wheel, a fine hair wheel, a big brush and the like dipped with pumice powder paste, and throwing the whole surface of the false tooth by using a dry cloth wheel dipped with polishing paste.
In summary, the following steps: according to the manufacturing method of the combined type oral cavity false tooth, the prepared combined type oral cavity false tooth has antibacterial property under the condition that the color and luster are not influenced, the combined type oral cavity false tooth is convenient to wear for a long time, the damage of oral bacteria to the combined type oral cavity false tooth can be reduced, the oral hygiene of a wearer can be improved, the prepared combined type oral cavity false tooth has better wear resistance and durability and ageing resistance, and the service life of the combined type oral cavity false tooth can be prolonged.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
