DENTURE AND PREPARATION THEREOF

摘要

PURPOSE:To easily and certainly prepare a denture having good fittability and physical properties within a short time by constituting a foundation base part of a thermoplastic resin while constituting a gum part of a photopolymerizable resin cured polymerizate. CONSTITUTION:The sheet like thermoplastic resin 2 on a gypsum model 1 is molded under heating and pressure to prepare a foundation base part. Artificial teeth 4 are arranged to the upper surface of the obtained foundation base part using a photopolymerizable resin 5 to form a gum. At this time, the photopolymerizable resin is polymerized and cured by the irradiation with light. By this method, the foundation base part is constituted of the thermoplastic resin and the gum part is constituted of the photopolymerizable resin cured polymerizate. By this method, a denture having good fittability and physical properties can be prepared easily and certainly within a short time.
