FIELD: medicine.
SUBSTANCE: invention can be used for 3D printing in dentistry, subsequent burning in molding box and casting of metal dental implants. Proposed dental burned photopolymer composition for 3D printing contains: oligoester acrylate, polyethylene glycol dimethacrylate, bisacylphosphine oxide and diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide in the following ratio of components, wt %: oligoester acrylate 40–80, polyethylene glycol dimethacrylate 15–55, bisacylphosphine oxide 1–3, diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide 1–3, anthraquinone bright blue 0.03.
EFFECT: development of dental burned photopolymer composition intended for 3D printing, subsequent burning in molding box and casting of metal dental implants, having low ash content and completely burning out at temperature of up to 300 °C.
