This invention relates to a backin for an artificial tooth, known in dental ar ance as a dummy, and used to replace a 0st natural tooth, the dummy being provided with pins projecting from its posterior face and inserted'in sockets located within a portion of a metallicbridge.
The object of the invention is to provide a metal backing permanently attachable to the bridge during the operation of making the latter, and constituting, when attached,
a fixture which includes a rigid tooth seat," and rigid-pin-recelvlng sockets, each 1mmovable relative to the bridge, the backing having metallic surfaces complomental to those of the posterior face and pins of the tooth, and adapted to be secured thereto by cement,
so that a dummy may be conveniently secured to the bridge, and a broken dummy may be removed and replaced by another, the rigidity of the metallic socket Walls incorporated in the bridge, rendering said walls free from liability of deformatlon, so that they cannot be closed or distorted, and are always in condition to receive the pins, whether of an original dummy, or of a dummy substituted for a broken one.
I have shown thebacking adapted for use with a tooth having a root extension, but
it will be obvious that it may be adapted for use with other typw of pin teeth.
Of the accompan ing drawings forming a part of this speci cation,j'
Figure 1 shows in perspective a backing embodying the invention, adapted for use with a tooth or dummy of the type referred to.
Figure 2 is a longitudinal section of the backing.
Figure 3 shows in perspective a tooth applicable to the backing shown by'Figure 1.
Figure 4: is a longitudinal section of the tooth shown by Figure 3.
Figure 5 shows the backing as in Figure 2, and the tooth as in Figure 4, and shows by dotted lines a bridge to which the backing is secured when in use.
Figure 6 shows in perspective a partly completed backing. a V
The drawings show the parts much enlarged.
The same reference characters indicate the same parts in all of the figures.
My improved backing comprises a thin plate 12, preferably of gold, having an outer bridge, accordin side conforming to'the posterior face 13, of an artificial tooth or dummy, from which pins 14 project, an inner side formed to bear on a bridge 15, and an integral rib 16, projecting from the inner side'and containing sockets 17, opening on the outer side, and adapted to receive the pins 14. The surfaces of the inner side and rib are adapt ed to be attached and adhere to the metallic material of the bridge 15, the latter being cast on or. soldered to said surfaces. The backing when thus attached, constitutes a fixture on the bridge, and its outer side and socketwalls are attachable by cement to the posterior face and pins of the tooth.
To minimize the quantity of metal employed in the backing, the length of the rib 16 may be less than the width of the plate 12, as shown by Figure 1, or the midlength portion of the ribmgy be interrupted by a recess, as shown by igure 6, which shows the backing partly completed.
The plate 12 may be bent to conform its outer side to the two faces forming a recess in a tooth of the character referred to, although, if desired, the bend may beomitted so that the plate will conform to a posterior face which is flat from end to end of the tooth. V v
The backing may be marketed in the form shown by Figure 6, its area being greater than that of the posterior face, so that a dentist may cut away the surplus marginal material in exact conformity to the margin of the tooth face.
The backing may be formed by suitable dies, adapted to form the external surfaces and the sockets, or the sockets may be formed by drilling, or otherwise.-
It will be seen that a dentist, supplied with the described backing, may readily incorporate the same as a fixture on a bridge by well known methods not requiring description, and that the pin sockets of the invcorporatedbacking are non-distortable, and
.In practice the bridge 15 is secured by well known means to natural teeth at opposite ends of a gap caused by the removal of one or more intermediate natural teeth. One or more backings may be secured to the to the number of natural teeth to be repl aced. When the tooth or dummy isof the type referred to, its root provided With pin receiving sockets that open through the outer face of the plate, 10 said .rib, preventing warping of the hacking plate transversely.
In testimony whereof I have aifixed my signature.
SIMON MYERSON.
