On June 8th, “The application seminar of 3D printing in the field of stomatologyâ€, Shao Bo, general manager of Jingwei Xincheng, told reporters. The seminar is the first time in the field of stomatology, public hospitals, private stomatological hospitals and clinics, denture processing and 3D printing equipment manufacturing enterprises, and the State Food and Drug Administration. Direction, we also want to understand the ideas of experts and companies, and be able to provide better services. â€
The “Application Symposium on 3D Printing in the Field of Stomatology†was jointly organized by the Editorial Board of China Journal of Stomatology and Jingwei Xincheng (Beijing) Technology Co., Ltd., and the State Food and Drug Administration approved four ministers Liu Bin and Zhonghua Dental. Yu Guangyan, president of the Medical Association, and Zhao Yimin, editor-in-chief of the Chinese Journal of Stomatology, and many other experts and industry-related enterprises attended the event.
It is understood that Jingwei Xincheng is a product solution provider dedicated to the development, sales and after-sales of digital solutions. At present, Jingwei Xincheng has successfully digitized medical dental models, digitized denture processing and digitalization of chairside treatment. Covers 70% of the customer base.
According to industry statistics, 94% of the population in China has dental problems. About one in 10 people have dentures installed, and the average annual consumption of dentures is 81.65 million. It takes 5.5 hours to print 100 teeth at a time. According to the imported powder price of 4000 yuan/kg, 1kg powder can print 600-700 teeth, and the cost of a single tooth is about 5-7 yuan. The data shows that the cost of traditional casting single teeth is about It is 20 yuan.
With the improvement of living standards, the denture customer's requirements for dentures are getting higher and higher. Traditional denture technology has long time, high technical requirements and high cost, while 3D printing dentures have short time, technical requirements and relatively low cost and comfort. High degree. To this end, some insiders judge that the future 3D printing denture will gradually become the mainstream of the denture market.
At the same time, the state is also encouraging to 3D printing. For example, in 2015, the “National Additive Manufacturing Industry Development Promotion Plan (2015-2016)†and “Made in China 2025†were successively introduced, and the additive manufacturing method represented by 3D printing was upgraded to the national strategic level. In addition, many provinces and cities have established a local 3D printing industry alliance, with 3D printing as a key development industry.
In fact, since the first digital CAD/CAM system was sold in China's dental industry in 2004, the multi-pattern of dentures has undergone earth-shaking changes. The industry has rapidly moved from a manual processing industry to automatic digital production and processing in more than 10 years. On the road to industry transformation.
Guan Qing, the deputy general manager of portable technology, which is a naked-eye 3D and 3D printing industry-wide product and service, and owns a number of invention patents and proprietary technologies, said that 3D printing technology is also called “additive manufacturing†technology, 3D printing. The most outstanding advantage of the technology is that it can directly generate objects of any shape from computer graphics data without machining or molds, thus greatly shortening the product development cycle, increasing productivity and reducing production costs, thus achieving customized production.
With the continuous development of 3D technology and dental materials, the application of personalized abutments, inner crown metal 3D printing, planting guides, and digital models has also been expanded. However, in the development of these fields, the dental industry customers are increasingly involved in the application of digital equipment, the upgrading of production processes and the approval system for 3D products.
Shao Bo pointed out that 3D printed dentures are safer than other implant technologies, but as emerging dental technologies, there are certain deficiencies. For example, at present, there is no denture 3D printing technology related courses in the Department of Stomatology in colleges and universities. Some students have not even contacted the dentures and are out of the market.
It is also known that the current research on 3D printing materials for oral implants is limited, the molding materials are mostly made of chemical polymers, and the physical properties of the molded products are poor. Nowadays dental 3D printing technology still has difficulty in popularization and bottlenecks, and the cost of imported printing equipment and consumables. High, and domestic equipment still needs further improvement in stability.
From the actual operation point of view, the use of 3D printing dentures also has some problems to be solved. Lu Li even bluntly said that the use of 3D printed dentures is not like teeth, far less manual than the craftsman. “I deliberately went to five technicians to conduct research and found that the problem lies in the software. The material has improved but the software has not kept pace. Many software programmers have not mastered the printing skills, and these are trainings, but currently severely lacking."
And 3D denture printing companies are more concerned about the approval of the State Food and Drug Administration. It is understood that the 3D denture printing classification belongs to the medical device industry, but the specific approval registration scheme in China has not yet been released. Liu Bin, the four ministers of the State Food and Drug Administration, has admitted that there is no specific timetable and it is recommended to establish a 3D denture printing industry alliance or industry association to increase independent research and development and to carry out scientific norms.
