A method and component devices for producing edentulous dentures. The method includes obtaining a cast impression of a jaw, any teeth and gingiva area with a first set of dental trays including selecting a properly sized upper dental tray (10) and a properly sized lower dental tray (50), applying impression material in each said tray and placing each said dental impression tray with said impression material in said oral cavity in order to deform uncured impression material. A second set of dental trays is utilized including a lower dental tray (100) having a contact plate (1 10) with an upwardly extending shoulder (1 12) surrounding a tapered opening, a ball nut (114) retained in the tapered opening, and a post (116) adjustably secured to the ball nut. A striking plate (122) is attached to a second upper dental tray (120) in order to accurately obtain an established occlusal vertical and centric relation positions. A third upper dental tray (200) with a wax impression is inserted for esthetic blue printing to establish the shape of the patient's upper lip and mouth. A third lower dental tray (220) with wax impression material (222) is utilized to determine functional position including tongue, cheek and Hp positioning.
