Furthermore, a snap ring is arranged on the denture base.
The second technical scheme is as follows:
a preparation method of a minimally invasive aesthetic bracket denture specifically comprises the following steps:
step 6, making a wax pattern on the plaster model with the teeth to obtain a wax pattern denture model;
step 7, putting the prepared wax denture model into a model box, and then embedding by adopting an embedding material;
step 8, after the embedding material is dried, putting the whole embedding box into a pot, and heating for 5-10 minutes by using boiling water; melting and discharging the wax to form a cavity;
step 9, injecting a molten thermoplastic resin into the cavity by using a stealth casting machine, and carrying out die-casting molding at 300 ℃ for 20-25 min; then cooling to normal temperature;
and step 10, after the embedding box is cooled to normal temperature, opening the cooled embedding box, removing redundant embedding materials, and grinding and polishing the surface of the denture to obtain the minimally invasive aesthetic bracket denture.
Further, the embedding material is anhydrite.
Further, the thermoplastic resin is fatty acid polyurethane resin.
Further, the tooth design software adopts dental EXO or 3shape software.
Compared with the prior art, the invention has the following beneficial effects:
1. the denture adopts the high-strength zirconia customized denture (Zernike brand), so that the service life of the product is greatly prolonged, and the denture can be specially customized by working procedures of digital scanning, cutting, dyeing and the like according to the personalized characteristics of the color, the shape and the like of the teeth of a patient, thereby improving the aesthetic degree and the simulation degree of the denture.
2. The traditional metal clasp type base is improved into the false tooth base made of fatty acid polyurethane resin, the false tooth base is free of any metal material, high in strength and good in wear resistance, can be made into a transparent material or a gum color imitation according to requirements, can be worn for a long time, and overcomes the defects that a metal bracket is not attractive, metal allergy is easy to generate, a hidden false tooth cannot be worn for a long time and the like.
3. Compared with the traditional bonded bridge prosthesis, the invention belongs to the repair of movable false teeth, is convenient for self-cleaning of oral cavity and avoids the possibility of displacement of the false teeth of the oral cavity and secondary caries.
4. The denture base made of the fatty acid polyurethane resin has very small denture base and snap ring, thereby greatly reducing the foreign body sensation in the oral cavity.
The invention can highly simulate the color and the shape of the mouth of a patient, forms a great breakthrough in the color and the shape, solves the defects of single dental plate of the traditional movable prosthesis, low simulation degree, unattractive appearance of the traditional metal bracket, easy generation of metal allergy, incapability of wearing the invisible denture for a long time and the like, and when in use, a clinician only needs to prepare a combining support without grinding natural dental tissues, thereby really achieving the minimally invasive aesthetic repair.
