PHOTOPOLYMERIZABLE DENTAL POLYMER RESTORATIVE MATERIAL COMPOSITION

Disclosed is a dental restorative material composition comprising a photopolymerizable monomer, a photoinitiator, ethyl 4-dimethylaminobenzoate, and 2-(dimethylamino)ethyl methacrylate. The composition has the strength thereof after polymerization gradually increased by controlling a curing speed, and thus may be easily processed immediately after polymerization while ultimately having excellent compressive strength, and, by having low shrinkage stress, enables improving a treatment environment of a patient. L'invention concerne une composition de matériau de restauration dentaire comprenant un monomère photopolymérisable, un photoinitiateur, du 4-diméthylaminobenzoate d'éthyle et du méthacrylate de 2-(diméthylamino)éthyle. La composition a sa résistance après polymérisation progressivement augmentée par régulation d'une vitesse de durcissement, et peut ainsi être facilement traitée immédiatement après polymérisation tout en ayant finalement une excellente résistance à la compression, et, en ayant une faible contrainte de retrait, et permet d'améliorer un environnement de traitement d'un patient. 광중합성 단량체, 광개시제, 에틸 4-디메틸아미노벤조에이트 및 2-(디메틸아미노)에틸 메타크릴레이트를 포함하여 경화속도를 조절함에 따라 중합 후 강도가 점진적으로 상승하여 중합 직후의 가공이 용이하면서도 최종적으로는 우수한 압축강도를 가지고, 또한 수축응력이 낮아 환자의 치료 환경을 개선 가능한 치과용 수복재 조성물이 개시된다.
