PROBLEM TO BE SOLVED: To provide an artificial tooth used for a plate denture that is a dental prosthesis device in which the keeping effect with a denture base material is maintained without depending on the adjustment of a crown length diameter.SOLUTION: An artificial tooth has an internal structure that includes a support part d and a groove space e surrounding the support, and secures the mechanical keeping force for the denture base material without depending on the adjustment of an artificial tooth length diameter. That is, the efficiency improvement of denture making becomes possible such that the reworking of a through hole or the like can be suppressed to the minimal. Moreover, the contamination of the junction with the denture base material by a micro leakage is reduced by disposing a protrusion c in an artificial tooth outer peripheral wall distal end, and the aesthetic effect is reduced. |
