PROCESS OF MAKING DENTAL PLATES BY ELECTRO DEPOSITION.
SPECIFICATION forming part of Letters Patent N 0. 397,320, dated February 5, 1889. Application filed April 11, 1887 Serial No. 234,341. (ModeL) To all whom it may concern:
Be it known that I, JOSEPH G. WARD, a citizen of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in the Process of MakingDental Plates by Electro-Deposition; and I do hereby 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 letters of reference marked thereon, which form a part of this specification.
In said drawings, Figure 1 represents a top or plan view of a plaster cast or impression of the upper jaw and a dental plate formed thereon, as comprehended in my invention; and Fig. 2 is a section on line X X thereof.
The object of my invention is to provide a process by means of which complete metal dental plates ready for the setting of the teeth may be produced by electro-deposition, and the steps in said process are essentially follows:
Casting a form from the mouth of the patient and then electro-depositing a substantially rigid plate thereon, substantially as set forth.
The following detailed description will more fully disclose the manner of carrying my said process into practice, several additional features being described to indicate what may further be done when desired.
In the drawings, A is a positive cast of the upper jaw, made in wax.
B is the plate, and C an additional thickness of either rubber or other material superposed on the plate.
The plate Bis an electro-deposited metal dental plate, and is produced in the following manner: Take a plaster cast or impression of the mouth or jaw, and from this cast get a positive in wax, in the usual manner. After this positive has become thoroughly dry} the surface is metallized or made conductive by applying bronze powder, plumbago or black-lead, or any other of the ordinary conducting agencies, and is then submerged in an electrolytic bath composed of any metallic saltssuch as are commonly em- I ployed in obtaining metallic electro-deposits,
as, for instance, cyanide of silver. After the metal or metals of which it is designed to make the plate through the agency of voltaic electricity have been deposited to a sufiicient thickness, the positive cast, with its deposit, may be removed from the bath and the plate removed from the cast and trimmed and finished up; but if it is desired to have the plate of increased thickness around the edge where the teeth are to be set, the cast, with the plate adhering to it, may be removed from the bath and all the exposed surface of the plate, except the portion to be thickened, may be covered with a coating of wax or other nonconducting substance and resubmerged in the bath and left there until the required thickness of plate around the edge is secured, when it is taken from the bath. Either with or without this additional thickness at certain points, the plate maybe covered on the outer side or a portion thereof with a layer or partial layer of vulcanized rubber or other suitable material, in the usual way; but the plate is complete and may be used without the rubber coating. 7
The deposit of silver may first be covered with a deposit of gold, platinum, or other metal not affected by the ingredients in the rubber when such is added, said deposit being of sufficient thickness to prevent the ingredients in said layers from chemically acting on the silver, and thus rendering the said layer soft and inefficient as a support for the teeth.
I do not claim the deposit of the two or more strata of metal in this application, whether it is to be followed by the superposed rubber or not, as I have made that feature the subject of a separate application for patent filed by me on the 17th day of November, 1888, Serial Having thus described my invention, what I claim, and desire to secure by Letters Fat 5 ent, is v 1. The process of producing ametal dental plate, which consists in first casting a form from the mouth of the patient and then depositing a substantially rigid plate thereon, 10o substantially as set forth.
2. The process of forming a complete metal dental plate l'eadyfoft hesetting of the teeth, have hereunto set my hand this 5th day of which consists in casting a form from the April, 1887.
