Application Of DLP 3D Printing Technology In Dentistry

Nov 20, 2020

The report of market research organization TMR shows: By the end of 2025, the global dental 3D printing market value will reach 3.441 billion US dollars, a growth rate of 16.5%. More and more dentists are beginning to use 3D printing technology to manufacture implants, such as crowns, bridges, and dentures. This is also driving the popularization of dental 3D printing in the future. Moreover, as the application of 3D printing technology continues to mature, the application of 3D printing in the dental field to the entire medical field can be said to be more and more extensive. DLP 3D printing is one of the more advanced 3D printing technologies nowadays. Its application in dental dentistry is quite extensive. Below I will briefly introduce you to several DLP applications in dental medicine.

1. 3D printing guides, the production of 3D printing guides, first register the direct or indirect scan data of the upper and lower jaw dentition with the patient's CT reconstruction of the jaw model, and then use the surgical virtual software to simulate the jaw bone based on the three-dimensional measurement results Osteotomy and moving operation, and finally design the guide plate required for the operation according to the virtual operation plan, and input it into the 3D printer to process it with DLP technology.

2. Invisible braces, in the traditional orthodontic treatment process, after the doctor obtains the patient's dental model, he manually saw off the teeth that need to be moved one by one, arranges the teeth to a movable position, and heats them. The film forming technology directly presses out the transparent braces for the patient to wear. The moving distance may only be 0.1 mm, which not only requires a lot of time and energy, but also requires the professional knowledge and manual craftsmanship of the operator. It also has a heavy plaster. The mold is not convenient for storage, transportation and communication between doctors and patients. 3D printing replaces the manual arranging of dental molds. You only need to arrange the digital dental molds on the computer to the ideal position through professional software. According to the orthodontic theory and big data results, use extremely precise Resin 3D printing resin dental molds at different stages can be used to press out transparent braces with the previous laminating process, and its accuracy and speed are naturally self-evident.

3. The dental model is an important reference standard for orthodontic treatment. The traditional plaster dental model is easy to age and fracture, and it is inconvenient to store. At the same time, the production process of the plaster dental model is low in efficiency and accuracy. The application of 3D printing technology to the manufacture of solid dental molds can reduce the pain of the patient's orthodontic treatment process, and also provide convenience for the doctor. Moreover, this method is more efficient and economical than the traditional manufacturing process, and has strong practical value.
