Ceramic tooth 3D printing production method in dental restoration industry

Abstract

The invention relates to the field of dental restoration, in particular to a ceramic tooth 3D printing production method in a dental restoration industry. The method includes a first step: scanning isperformed; a second step: a ceramic tooth machining center designs 3D ceramic tooth simulation model files; a third step: a 3D printer produces a prototype of a to-be-restored body required by a doctor; a fourth step: after the printing is completed, a support is removed from the prototype of the to-be-restored body, and the prototype of the to-be-restored body is placed in a crystallization furnace for sintering and degreasing; and a fifth step: the sintered prototype of the to-be-restored body is subjected to soaking dyeing or coloring and then undergoes high-temperature crystal forming, sothat the whole product is manufactured. The ceramic tooth 3D printing production method in the dental restoration industry has the advantages that the manufacturing cycle is short, the quality stability is high, the cost is greatly reduced, the industrial mass production can be performed, and the digital production level is high.

Description

technical field [0001] The invention relates to the field of dental restoration, in particular to a production method for ceramic teeth 3D printing in the dental restoration industry. Background technique [0002] In the traditional production of pottery teeth, the doctor performs clinical treatment on the teeth that need to be restored by the patient, obtains a plaster model, and mails the plaster model that needs to be made into pottery teeth to the pottery tooth processing factory through the salesman of the pottery tooth factory or the salesman of the courier company. Technicians need to go through plaster-wax engraving-casting-car gold-OP-pile porcelain-shape repair-glazing-polishing-disinfection treatment-packaging-mailing to the hospital or dental clinic, so that the doctor can install dentures for the patient. This method has the following problems: [0003] 1. The production cycle is long: it takes 5-10 days to work, and it takes 3-5 days for out-of-town processing...

AI Technical Summary

Problems solved by technology

[0003] 1. The production cycle is long: it takes 5-10 days to work, and it takes 3-5 days for out-of-town processing or OEM OEM express delivery for foreign parts;

[0004] 2. High degree of dependence on labor: all the processes in the production of existing pottery teeth are basically completely completed by technicians;

[0005] 3. Poor quality stability: In the traditional process, doctors take molds, ceramic technicians count the number of processes, because it is completely done manually, it will vary depending on the degree of technical familiarity of personnel, process flow, machine accuracy, environment, material quality stability, and operation. Methods and many other reasons lead to the instability of quality. Usually, the pass rate of ceramic tooth processing quality can only reach about 85-95%. ;

[0006] 4. High production cost: Due to the traditional production process, it involves salesperson expenses, mailing costs, salaries of ceramic technicians in each process, management costs and other comprehensive costs. At the same time, due to the macroeconomic environment, prices and labor wages continue to rise. It is close to 80-90% of the cost of sales, and some ceramic tooth enterprises have no profit
