The development of 3D printing complete denture and oral cavity 3D printing denture model technology under the overall digital trend

2022-01-06

Fully moving towards digitalization is the steady development trend of the international dental processing industry. As a manufacturing technology with significant digital features, 3D printing technology has become a link in the dental digital processing chain. And through the data stream, the oral diagnosis, design, and production processes are linked together to form a fully digital process for dental product processing.

With the development of dental 3D printing technology, the application of 3D printing in the production of dental final products has increased. From the most common 3D printed metal crowns and removable denture brackets, it further expands to the manufacturing of 3D printed dental implants, invisible orthodontics, and veneers. Photopolymerization 3D printing technology has expanded from indirect applications such as manufacturing dental molds, casting models, and surgical aids to applications in the production of final oral products. This is mainly due to the development of new materials for oral 3D printing.

Light-curing 3D printing technology to manufacture the final product

PioNext DLP technology planting guide, section printing

PioNext's latest product desktop printer DJ-89 adopts DLP light curing technology and is widely used in the manufacture of implant guides, wax brackets, wax crowns, temporary crowns, invisible orthodontics, etc.

The machine is easy to operate and molds are quickly formed. It already has a certain market share in the dental industry in the United States. PioNext DJ-89 has a large printing platform, which can print 7 denture bases in 90 minutes, 8 indirect bonding trays or dental molds in 30 minutes, and 120-140 wax models in only half an hour. This greatly improves the speed and accuracy of the dentist's diagnosis and treatment of patients, which has attracted much attention.

Digital denture material

Today, 50 million dentures are produced globally every year, but only 1% are produced using digital tools. Traditional denture manufacturing is a complicated manual technique, and the dental technicians have a long cycle of training skilled technicians to master this technique. And efficient and economical 3D printing denture solutions can greatly expand the production of dentures. According to calculations, the material cost of 3D printed complete dentures is about US$3 per piece, while the cost of using traditional denture cards and acrylic is US$50. The use of 3D printed denture materials has reduced the cost by 5 times.

In addition, the most significant difference between the digital denture solution and the traditional denture manufacturing process is that it reduces the dependence on manual experience and obtains accurate, consistent, and high-quality results through digital technology.

So today or in the next few years, oral 3D printing technology will enter the stage of strength. Metal 3D printing equipment, light curing 3D printing systems and materials, the application of these technologies penetrates into the fields of oral restoration, orthodontic product design, and final product manufacturing to solve various oral problems that need to be solved.

Dental 3D printers have been in the dental industry for a long time. In the past 20 years, it has been very active. However, in the past five years, the biggest change in dentistry and 3D printing is actually the affordability and ease of use of the system. Most importantly, improved biocompatible materials that can be used directly in the oral cavity.
