Abstract
The present invention entails a partial denture formed of a relatively hard acrylic material. Molded into a selected portion of the denture is an area of relatively soft material. A teeth opening is formed in the soft material, the opening being at least slightly elongated to receive at least two successive existing teeth of the subject. Forming a part of the soft material and the existing teeth opening is an elastic retainer strip that engages the gum area of the subject adjacent the existing teeth. The elastic retainer strip engages or grips the subject's gum, resulting in the partial denture being secured within the subject's mouth.
