To provide a prosthesis for a dental surface that has the same rear resistance and aesthetic property as a conventional hard resin, does not require a careful formation of an abutment such as an abutment tooth as previously or the extraoral manufacture of an indirect dental prosthesis and can form a dental prosthesis in a short time in the case where the manufacture of a dental prosthesis is necessary because of the damage to or loss of a tooth.
This prosthesis 1 for the dental surface shaped by following the labial side of a foretooth, the malar side, the adjacent sides or the occluding side of a molar, the reverse side of which is joined to a lingual tooth formed by filling a resin material 4 for molding a lingual tooth on the abutment 3 is formed of a polymer of a compound having an unsaturated double bond and can be polymerized and a mixture of a filler and a polymerization initiator. The prosthesis may be in the form of a veneer 0.1 to 2 mm in thickness or has a protrusion forming a hole or a groove into which a post planted in the root of a remaining tooth gets into or engages with the reverse.
