In the 21st century, the emergence of digital imaging diagnosis and treatment methods and computer program-controlled processing technology has opened up the road to aesthetic, minimally invasive, fast and accurate diagnosis and treatment of oral restoration, and oral medicine is developing towards fully digital medicine. The restorative devices used in clinical dental restoration (all-ceramic crowns, inlays, veneers, bridges, etc.) are individually designed and manufactured according to the patient's missing teeth, and are highly personalized. 3D precision rapid prototyping processing technology can well meet manufacturing requirements such as precision, speed, and aesthetics. However, the types of direct dental restorations produced by 3D printing are currently limited, and materials are the bottleneck of research. If the rapid prototyping of 3D printing nanoporcelain resin restorations is realized , it will not only greatly improve the processing efficiency and production accuracy of oral porcelain restorations, but also save labor costs and reduce consumables. Realize immediate clinical diagnosis and treatment of all-ceramic restorations and advance the digital level of dental medicine.

This research is mainly to explore new 3D printing materials and new manufacturing processes for dental restorations. This project mainly studies from two aspects, one is the design of equipment and processes, and the other is the design and proportioning of materials. Verify the feasibility of 3D printing to directly manufacture full crowns, inlays, and veneers for restoration from the laboratory stage, provide more applications for the promotion of 3D printing technology in digital manufacturing, and promote the application of 3D printing equipment in dental clinics for chairside medical treatment. schedule.
