TOOTH-BRIDGE.
Specification of Letters Iatent.
Application filed February 10,1913. Serial No. 74?,422.
To all whom it may concern:
' Be it known that I, FRIEDRICH SCHREIBER, dentist, a citizen of Germany, residing at Berlin, Grermany have invented new and useful Improvements in 'looth-Bridgeibf which the following is a specification.
This invention relates to artificial dentures in the form of bridges, employed to fill a gap in the mouth of one or more artificial teeth.
The object of the present invention is to obviate as much as possible any great dis comfort to the patient and to render it unnecessary to crown the natural teeth on each side of the gap with gold crowns.
Broadly speaking, the present invention comprises a bridge formed in two longituthis invention employs a portion of the bridge itself to form the biting surface of the artificial tooth or teeth.
In the accompanying drawings :-Figures 1 and 2 show a portion of'a lower jaw having a tooth gap viewed from above and from the side respectively. Figs. 3 and 4 show the same views provided with one constructional form of the new tooth bridge.- Fig. 5 shows the separate halves of the new tooth bridge in lan view. Figs. 6 to 8 show transverse "sec 1011s through various constructions of the new tooth bridge.
The new tooth bridge is composed of metal and comprising two halves A, A
placed side by side in the longitudinal direction. The ends are formed as clasps B,
B to be applied sidewise on each side of the tooth gap against the adjacent natural teeth C, and when necessary also upon their biting surfaces, and the bridge halves are then secured together by means of screws D or the like. The ends B, B are so fitted to the natural teeth 0, that they prevent any displacement of the bridge toward the biting surfaces or in the opposite direction and do not injuriously affect the right bite. Corresponding to the special circumstances of each case, the halves A, A of the tooth bridge will receive a shape such as is illustrated'in Figs. el'to 8, or of some other section. If, for instance, the section be chosen as shown in Fig. 8, then the biting surface of the artificial tooth or teeth will have no slot. The invention is not limited to the constructions illustrated. Thus for instance the new tooth bridge can be used simultaneously for several tooth gaps which are separated by one or more 'natural teeth. In this case it may suflicc in special circumstances if the tooth bridge in addition to being attached to the natural tooth or teeth which are between the gaps, is fixed only to the natural tooth on the far side of the one gap. Consequently, the tooth bridge will support the artificial tooth or teeth requisite for the filling up of the second gap without a third point of support.
Between the gum E and the bridge supporting the artificial tooth or teeth there may be left a space (Fig. 6) which can' readily be cleansed in order to prevent theaccumulation of remains of food and so forth. Or the bridge may be caused to touch the gum within the gap. In this case (Figs. '7 and 8) the bridge is preferably sloped off from the inside underneath so that inthis case also the proper cleansing of the gum E can take plac As hereinefore described andillustrated .in the dra ing, the middle part of the bridge forms itself the artificial tooth or teeth, which thus would be from gold or another noble metal. It is however also pos- Patented Nov. 10, 1914. l
sible to employ porcelain teeth in connection with thenew bridge. For this purpose, the middle part of thelatter is. only to be made narrower, and the porcelain teeth are fixed to it in any known or special manner.
As shown in Fig. 9 of thedrawing, the bridge A is constructed in accordance with the foregoing disclosure with anchoring means, and the said bridge has porcelain teeth A secured to it in well known manner.
lVhat I claim is I 1. A metal tooth bridge comprising two halves adapted to be placed side by side in the longitudinal direction of the gum, each half having clasps at both endsfitting laterally about the abutment teeth, and means for tightening said halves together.
the artificial teeth necessary for filling the gap and having clasps at both ends fitting laterally about the abutment teeth, the middle portions of the bridge halves overlapping each other, and means for tightening said halves together.
In testimony whereof I afiix my signature in presence of two witnesses.
