Benefits of technology

This patent describes a new type of material that uses special plastics instead of traditional metal or ceramic materials. It also includes a dental filling material added during production. These materials are safe and effective but they don't make it easier than regular teeth due to their lack of biocompatibility.

Problems solved by technology

The technical problem addressed in this patent text relates to developing a low-cost 3D printing material for creating temporary dental devices without requiring expensive equipment and training. Current methods require multiple steps such as selecting and attaching paper layers, laser sintering, and casting melted resin onto teeth. These techniques have limitations in terms of speed, accuracy, and cost efficiency.

Embodiment Construction

[0015]The present invention provides a three-dimensional printing article for making dental products, comprising: a compound made of about 20 to about 80 wt % of Ethoxylated bisphenol A dimethacrylate (BisEMA) (Formula I), preferably, said Ethoxylated bisphenol A dimethacrylate comprises ethoxyl chain with n=2, and m=2, 4 or 10;

about 0 to 75 wt % Diurethane dimethacrylate (UDMA) (Formula II);

about 0 to about 10 wt % Triethylene glycol dimethacrylate (TEGDMA) (Formula III); and

about 0.01 to about 10 wt % of a photo-initiator, preferably, the photo-initiator is Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide (TPO).

[0016]Preferably, said compound further composing: about 0 to about 10 wt % of Trimethylolpropane triacrylate (TMPTA) (Formula IV);

[0017]In one embodiment, the three-dimensional printing article for making dental products, comprising: a photoresist, wherein the photoresist is consisted of about 0.1 to about 10 wt % of silicon dioxide or silylated silicon dioxide, and about 0.
