Application filed August 26, 1921. erial No. 495,613;
To all 40. mm it may concern:
Be it known that I, HERMAN E. S. {Jr-rains, a citizen of theUnited States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Removable Dentures, of whichthe following is a specification.
This invention relates to removable dentures of the general type described in Patent N 1,366,058, Jan. 18, 1921.
The objects of the present invention are, as in the invention described in the patent referred to, to provide a removable dental bridge member which is Capable of slight movement under the stress of mastication, which can be made up of interchangeable standardized parts, and in which the connecting means between the bridge and its supporting piers form an actual part of the occlusal surface of the dental arch.
A further object of the invention is to'provide a tongue and socket connecting means in which the socket does not open to the occlusal surface but is covered by a dental member forming part of the connecting means.
I have found that by providing downward- 1y extending socket in seats inlaid in the lower part of the bridge-facing sides of the pier teeth, the socket can be overlaid or covered by artificial denture members rigidly.
connected at one side to the terminal teeth of the bridge work, each denture member having a tongue extending downwardly from its lower face for engagement with a socket. Preferably the denture members included in the connecting means are formed to replace the portions of the pier teeth which were removed in seating the socket members. This and other features of the invention will be hereinafter more particularly described.
In the drawings, in which a preferred embodiment of the invention has been selected for illustration V Figure 1 is a view in perspective of a clental arch in which is included a removable bridge member embodying the invention.
Figure 2 is a detail View partly in side elevation and partly in section showing the means for connecting the bridge member to the pier teeth.
Fgure 3 is a plan view of a bridge-supporting or pier tooth, fitted with, a socket member forming part of the invention.
'material.
Figure l is a vertical section ofthe pier 1 tooth shown in Figure 3.
F igure 5 1s a view in end elevation of a dental bridge member equipped with means .for connecting the bridge member to a pier tooth. Figure 6 is a plan view of the device shown in Figure 5.
Figure 7 is a view inside elevation of the device shown in Figure 6. I
Figure 8 is a view of a modified form of tongue shown in position in a socket member illustrated in section.
Referring to the drawings for a more detailed description, a complete dental arch is shown at 5 in Figure 1 in which is included a removable bridge member 7 made up of two artificial teeth 9 mounted on a base or saddle 11 formed of gold or other suitable The bridge teeth 9 are provided respectively with connecting members 12 which are in turn provided with laterally extending anchoring lugs 13 that are embedded in the adjacent lateral faces of, the bridge teeth, as is best shown in F gures 6 and 7 of the drawing. The members 12 are also provided with lugs or tongues 15 projecting downwardly from the under sides thereof as is indicated in Figures 5 and 7 of the drawing.
A suitable socket member for receiving the tongue 15 takes the form of a seat 17 mounted in the bridge-facing side of a pier tooth 19, as indicated in Figures 2 and 4: of the drawing. The seat 17 consists of a block' of suitable non-corrosive metal having a relatively horizontal surface or shelf 21 formed in a plane interi'nediate the gum and the operating surface of the tooth, the surface 21 serving as a seat on which to receive the member 12. A socket 23 entering the member 1? from the surface 21 receives the tongue 15 as indicated in Figure 2 and serves to anchor or hold the bridge member in its place.
The tongue 15 and the slot 23 have, as will be seen, a relatively thin or flat formation along the row of teeth and a relatively wide or elongated construction transverse to the row. This produces an exceedingly staple anchoring effect so far as concerns longitudinal movement of the bridge in its seat but permits a slight up and down movement of the bridge and even a slight lateral rocking movement of the bridge structure. The latter function is facilitated by forming rounded corners on the tongue '15 as at in Fig. ure 5 of the drawing. This effect maybe still further enhanced Where desired by removing'a small amount of metal from the opposite edges of the tongue at its point of emergence from the member 12, as at27 in Figure 8. In order to provide a Wear piece forthe outwardly facing surface of the mem- ,ber12, thesocket member '17 is preferably provided with an upwardly extending abutment member 29; \vhiclralso assists inthe inlaying or anchoring of thesocket mem V fiber in the pivot tooth structure.
It will be seen that an effective connecting 1 means bet veen the bridge member and the supporting of pivot tooth has been provided in which theconnecting member itselffo-rms a dental member.
What is claimed iszr 1.111 a device for connecting dental bridge members to supporting parts, a seat mounted in a tooth structure and having mounted in a tooth structure and occupying 7 a substantial part of the horizontallcross section thereof, said seat having a support mg surfacesubstantially parallel to the occlusal surface of thedental arch and an elongated socket extending intothe seat from said surface, a dental member formed to rest on the supporting surface of the seat, the seat-engaging surface of SZLlCl dental member having ato'ngue fitting said elongated.
In a device for connecting dental "socket, saidelongated socket and tongue 'eX- tending transversely'of the dentalfarch, and a rigid connection between the dental memberand the adjacent face of the next adjacent tooth in the bridge structure,

In a, device for connecting, dental bridge members to supporting parts, a seat mounted in a tooth structure and having a supportingsurface substantially parallel to the occlusal surfaceof the dental arch, said seat having an'elongated socket extending therein from the supportingsurface, a den talinember formed to engage said.support-' ing surface in covering relationto said slot and provided With a tongue member fitting into the slot, said tongue and slot extending transversely of the dental arch and formed to permit slight rocking movement of the engagedparts, and a rigid connection between the dental'member and the "bridge structure.
