Description
March 24, 1942. H. J. SHEEDY BISECTIONAL LOWER DENTURE Filed July 21, 1939 Patented Mar. 24, 1942 BISECTIONAL LOWER DENTURE Harry J. Sheedy, Scranton, Pa.
Application July 21, 1939, Serial No. 285,694
1 Claim.
This invention relates to artificial dentures and has for an object to provide a full lower artificial denture which is center balanced.
lhe denture of my invention is made by dividing an artificial denture medially along a perpendicular plane extending from front to back of the denture or corresponding to the anterior center of the lower jaw. By this division, two distinct half sections of the denture are produced.
Other objects and advantages will be apparent from the following detailed description of a preferred embodiment of the invention, reference being had to the annexed drawing, in which:
Figure l is a plan view of a lower denture embodying the invention;
Figure 2 shows one half-section of the denture of Fig. 1 including the threaded socket; and
Figure 3 shows the other half-section of the denture carrying the screw for entering the socket on the other complementary section.
In Fig. 1 is illustrated a lower denture parted along a plane l extending medially from front to back of the denture so as to divide the denture into two complementary sections designated A and B. The sections present fiat faces in approximately abutting relation, and the two parts are held together by a male and female connection comprising a threaded socket 2 embedded in the flat abutting face of denture section A and a screw 3 projecting perpendicularly outward from the fiat abutting face of denture section B. By rotating the screw 3 within the socket 2 the two sections are drawn into loose face-to-face contact to adjustably lit the denture to the jaw and to retain the parts in assembly.
When the denture is in place within the mouth seating upon the lower jaw, the denture sections A and B are free to yield independently of one another about the screw-and-socket connection 5 (which I term a center balance or pivot) so that during the process of mastication unequal chewing stresses upon opposite sides of the denture do not unbalance the denture.
The denture described above may be made of any suitable material, and the lit of old poorly fitting dentures may be improved by modifying them to include the center balance feature as set forth in the foregoing description, The denture sections A and B may be detached from each other for cleaning by simply unscrewing pair of complementary half sections each comprising a side and front portion of the denture, said sections being provided with vertical 0pposed flat faces substantially in abutting contact, a screw-threaded socket embedded within one 5 of said sections and opening through one of said fiat faces and a screw extending perpendicularly outward from the other of said flat faces and adapted to engage the socket in the other section, the sections being connected solely by the screw-and-socket joint whereby the sections are positively retained in assembly while permitting free and independent angular movement between the sections about the axis of the screw.
