  • Patent number: 4583947
    Abstract: Customized dentures are manufactured by first producing denture bases in one of a plurality of standard sizes each having sockets therein for receiving an array of artificial teeth. Next, an array of artificial teeth removably coupled together by means of a U-shaped appliance which maintains the occlusal aspects of the teeth is positioned in the sockets. Such denture bases which may be wax, uncured synthetic resin or a cured synthetic resin are then shipped and inventoried by a dentist. To fit a particular oral cavity, the dentist first makes an impression of the oral cavity and from that impression upper and lower models are casted. The dentist then selects a denture base having the artificial teeth positioned thereon in one of the standard sizes which most closely accommodates the models. The denture bases are then conformed to the surface contours of the models and the prosthetic teeth are secured in the sockets.
