Denture alignment kit

Claim 1

A method of facilitating the accurate positioning of artificial teeth during the setup stage in the fabrication of full dentures, which comprises the steps of contacting a lower record base with an occlusal guide comprising a rigid transparent sheet with a rear edge, said contact being between said rear edge and the retromolar pads of said base, while said guide is positioned in the contemplated occlusal plane of said dentures, contacting a cusp ridge locator comprising a rigid wedge-shaped sheet having adjacent first and second edges meeting at an acute angle at said first edge with the ridge crest of said lower record base, said locator being wedged between said guide and said lower record base in a position substantially normal to said guide with said second edge of said locator resting against the lower surface of said guide, and visually projecting the contact point of said first edge with said ridge crest onto said guide with the aid of one of a series of parallel lines inscribed on a surface of said locator normal to said second edge and extending from said second to said first edge, and marking said projection on the upper surface thereof, repeating said contacting and projecting steps to establish a progression of said projected contact points constituting transfer of the crest line of said lower ridge crest to said upper guide surface.

Claim 2

A method of facilitating the accurate positioning of artificial teeth during the setup stage in the fabrication of full dentures, which comprises the steps of contacting a lower record base with an occlusal guide comprising a rigid transparent sheet with a rear edge, said contact being between said rear edge and the retromolar pads of said base, while said guide is positioned in the contemplated occlusal plane of said dentures, contacting a cusp ridge locator comprising a rigid wedge-shaped sheet having adjacent first and second edges meeting at an acute angle at said first edge with the ridge crest of said lower record base, said locator being wedged between said guide and said lower record base in a position substantially normal to said guide with said second edge of said locator resting against the lower surface of said guide, and visually projecting the contact point of said first edge with said ridge crest onto said guide with the aid of one of a series of parallel lines inscribed on a surface of said locator normal to said second edge and extending from said second to said first edge, and marking said projection on the upper surface thereof, repeating said contacting and projecting steps to establish a progression of said projected contact points constituting transfer of the crest line of said lower ridge crest to said upper guide surface.
