ABSTRACT:
The present invention relates to a partial denture that includes a series of artificial teeth along with an opening formed on a ridge portion of the denture for allowing existing teeth to extend therethrough. In a preferred embodiment the partial denture is basically comprised of a relatively hard acrylic material. Around the opening formed in the ridge there is provided a relatively soft material and this includes an elastic strip that is formed in the partial denture adjacent the opening formed in the ridge for existing teeth. The elastic strip is molded adjacent the ridge opening and is particularly integrally molded with the relatively hard acrylic material that forms a substantial part of the partial denture. To assure a secure connection between the elastic retainer strip and the relatively hard acrylic material, there is provided a generally curved S-shaped molded joint between each end of the elastic retainer strip and the relatively hard acrylic material.
