DENTAL PROSTHESIS

An object of the present invention is to provide a dental material, particularly, a dental prosthesis, having excellent properties such as hydrophilicity and antifouling properties. The dental prosthesis according to the present invention includes a monolayer film obtained by curing a composition including: a compound (I) having at least one hydrophilic group selected from anionic hydrophilic groups and cationic hydrophilic groups, and at least one functional group with a polymerizable carbon-carbon double bond; a compound (II) having two or more functional groups with a polymerizable carbon-carbon double bond (wherein the compound (II) has no anionic hydrophilic group nor cationic hydrophilic group); and a surfactant (III) having a hydrophilic moiety including an anionic hydrophilic group, a cationic hydrophilic group or two or more hydroxyl groups, and a hydrophobic moiety composed of an organic residue (wherein the surfactant has no polymerizable carbon-carbon double bond).
