  • Patent number: 5376005
    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.

  • Patent number: 5364269
    Abstract: The present invention entails a partial denture that is basically constructed of a relatively hard acrylic material and includes a series of artificial teeth implanted along the ridge of the denture. The denture is particularly designed for a certain patient and is provided with at least one existing tooth opening for accommodating certain existing teeth of the patient. Formed about the buccal flange area of the denture and adjacent the existing tooth opening is an elastic retainer strip that is integrally molded with the relatively hard acrylic material of the denture. This elastic retainer strip engages the patient's gum in front of the existing teeth that project through the opening in the denture. On the opposite side of the existing tooth opening and opposite the elastic retainer strip there is provided a metal filler panel that is also bonded or integrally molded with the relatively hard acrylic material.
