LOUIS E. IIOUGI'I, OF HAMILTQN, VIRGINIA.

DENTAL BITE-PLATE.

SPECIFICATION forming part of Letters Patent No. 650,464, dated May 29, 1900.

Application filed April 10, 1900.

To all whom it may concern.-

Be it known that I, LOUIS F. HOUGH, a citizen of the United States, residing at Hamilton, in the county of Loudoun and State of Virginia, have invented certain new and useful Improvements in Dental Bite-Plates; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to dental appliances, and has for its object the production of an improved bite-plate which is employed in connection with the making of artificial upper and lower dentures and by the use of which absolute accuracy in articulation is insured. The invention in its preferred embodiment is set forth in detail in the following description and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a bite-plate embodying myinvention. Fig. 2 is a sectional view showing the application of the plate.

Referring to the said drawings by letter, A denotes the bite-plate, which is preferably constructed of metal, with side fiat plate members a a, connected at their forward end by a curved piece a. of wire, whereby lateral adj ustment of the plates a is permitted. Secured centrally to the part a and extending rearwardly therefrom is a flat strip a which may be of the same material as the plates at. This strip for a portion of its length is in the plane of the plates a, but beyond said portion it is inclined upwardly and its free end is bent cylindrically to provide a curved abutting surface a The plates and strip are provided with oppositely-extending projections a a.

In practicing my invention, the wax impressions being taken, the bite-plate is pressed against the under side of the upper impression B and is held thereagainst by the engagement of the upper projections a with the wax. The impressions are then fitted to the mouth of the patient, the introduction of the upper impression, carrying the bite-plate, bringing Serial No. 12,341. (No model.)

the abutment (L3 against the roof of the mouth. The lower jaw of the patient is now raised, and during such movement the tongue is elevated to the roof of the mouth and pressed against the abutment. As the jaws close the lower projections on the plate enter the upper surface of the lower impression B, and the impressions are thus held together.

It has been found in practice that the greatest accuracy in the bite or articulation is obtainable when the tongue of the patient is elevated against the roof of the month. No means has, however, prior to this invention been devised whereby such position of the tongue is insured, and one of the objects of my invention is to provide means which encourage such position, I having found by practice that the patients tongue naturally presses against the abutment, the pressure being maintained so long as the plate remains in the month. With the tongue exerting pressure against the abutment the movement of the lower jaw is accurately controlled, so that when the attached impressions are removed it will be found that the proper bite or articulation is secured.

Various modifications in details may be made, and I do not therefore limit myself to the construction shown and above described.

I claim as my invention- 1. A dental bite-plate having an upward extension providing a tongue-rest or abutment.

2. A dental bite-plate having oppositelyextending projections to engage an upper and a lower impression, and a separate tonguerest or abutment adapted to bear against the roof of the mouth.

3. A dental biteplate capable of lateral adjustment having oppositely-extending projections to engage an upper and a lower impression, and a tongue-rest or abutment ex tending upwardly from the plate and adapted to bear against the roof of the mouth.

In testimony whereof I affix my signature in presence of two witnesses.

LOUIS F. l-IOUGI-I.
