Technical Field
The invention belongs to the technical field of design and manufacture, relates to a method for manufacturing a removable denture, and particularly relates to a method for manufacturing a digital removable denture.
Background
With the increasing degree of global aging, the number of middle-aged and elderly people is gradually increased, so that the demand for false teeth is more obvious. According to the survey data of China, the average number of teeth missing of middle-aged people of 35-44 years old is 2.12, the average number of teeth missing of middle-aged people of 55-64 years old is 5.95, and the average number of teeth missing of middle-aged people of 65-74 years old is 9.06. For the people with tooth deficiency, the restoration treatment is generally carried out by three ways, namely fixed denture restoration, implant restoration and movable denture restoration. Most of people over 60 years old are patients with residual teeth and edentulous jaws, and the residual teeth patients are generally repaired by adopting a method of implanting or moving false teeth. However, since patients are over-aged or suffer from diseases such as heart disease or hypertension, and cannot be repaired by implantation, only removable dentures that are relatively economically safe can be selected for repair, and thus market space and market demand for removable dentures have become large.
The movable false tooth is a kind of prosthesis which is supported by natural tooth and base covering mucosa and bone tissue, and depending on the fixing body of false tooth and the fixing function of base, the artificial tooth recovers the shape and function of lost tooth, and uses base material to recover the shape of defective alveolar ridge and soft tissue, so that the patient can take off and wear it by himself. Generally comprises an artificial tooth, a base, a retainer and a connector.
Traditional removable denture preparation adopts the silicon rubber die to obtain patient's oral cavity structural morphology, and the doctor is posted the die for the denture processing factory, and the denture processing factory carries out the gypsum and pours into after receiving the die. Filling the concave on the poured plaster, and manually designing and manufacturing the wax-type bracket with the casting channel. And embedding the wax-type stent in an embedding material, pouring the heated cobalt-chromium alloy solution after the wax is lost and sintered out of the cavity, and manually removing the casting channel after cooling to polish and polish the cobalt-chromium stent. Coating a separating agent on gypsum, putting the polished cobalt-chromium bracket on the gypsum, manually arranging teeth, carving a wax-type base, taking an impression of the cast by using silicon rubber after the production is finished, respectively punching an injection hole and a drainage hole on the lingual side and the buccal side, fully boxing the cast and the silicon rubber together, and boiling out wax at high temperature to form a cavity. Injecting a mixture of denture powder and denture water into the cavity at the punching position, taking out the mixture after a period of high temperature and high pressure, separating the injected removable denture from the plaster and the silicone rubber, manually polishing, and sending back to a doctor after the plaster model is qualified in trial wearing.
A flow chart of a conventional removable denture manufacturing method is shown in fig. 1.
By adopting the traditional removable denture manufacturing method, the technical requirement on a technician is high, the manufacturing period is long, the precision is low, and the rework rate is high; therefore, how to make a digital removable denture have higher precision and short making period is a problem to be solved at present.
