EDWIN TELLE, OF NEW ORLEANS, LOUISIANA.

METHOD OF MANUFACTURING DENTAL PLATES.

Specification of Letters Patent.

Patented Dec. 3%,1913.

Application filed. November 5, 1912. Serial No. 729,619.

To all whom it may concern:

Be it known that I, EDWIN TELLE, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Methods of Manufacturing Dental Plates; 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.

My invention relates to an improved method of forming dental plates, as herein described and claimed.

The ObJBOt of my invention 1s to provide improved methods of forming dental plates for upper sets Constructed with a new type of adhesion along their outer circumferences and having a free clearance space over the palatine surface.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views :Figure l is a perspective view, illustrating a thin dental cup, having its outer circumference roughly coated with strips of impression material; Fig. 2 is a side view of the device shown in Fig. 1; Fig. 3 is a similar view of the same plate, showing the circumferential strips impressed and trimmed to proper width in the carrying out of my improved method; Fig. etis a section on the line 4- .1: of Fig. 2; and Fig. 5 is a section on the line 55 of Fig. 3.

Referring to the drawings, 1 indicates a special dental cup of thin rubber, metal, or other suitable material, which I construct in the usual way for each month in order to insure a snug fit. On the outer circumference of the cup 1, I apply strips 2 of impression material of suitable width and thickness. I then heat the impression material 2 to render it sufliciently plastic, and adjust the cup in the patients month by gentle pressure to flatten the impression material and obtain an accurate impression thereof. The plate is then removed and the sides of the flattened and impressed strips of impression material trimmed to proper width, as shown at 3 in Figs. 3 and 5. The cup is then replaced in the patients mouth, after being heated to render the impressed and trimmed impression material plastic, and the air exhausted from beneath the cup by suction exerted by the patient, thereby producing a strong uniform pressure over the entire surface of the cup, which forces the impressed plastic material accurately to the surface of the month. For mouths in which it is exceptionally difficult to secure afirm or satisfactory adhesion, the above step may be repeated and additional impression material applied to parts of the cup is necessary. After firm adhesion is thus obtained on the outer circumference of the dental cup, I form in any well known manner a plaster mold of the latter, in which a dental plate of rubber, celluloid, aluminum, or other suitable material, can be formed having a firm adhesion on its outer circumference and a free clearance space over the palatine surface.

By my invention, the strips of impression material around the entire outer circumference of the dental cup cover a relatively soft surface in the mouth and permit a free clearance space above the palatine surface of the cup, thus enabling an eflicient adhesion to be obtained that is vastly superior to the usual types of suction chambers and rubber disks.

I claim The herein described method of manufacturing dental plates, which consists in preparing a thin dental cup, coating the outer circumference of said cup with impression material, heating the impression material to render it plastic, pressing the cup to position in the patients mouth to accurately impress the plastic impression material, trimming the impressed plastic material to proper width, flasking the cup, and replacing the impression material with rubber or other suitable material.

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

EDWIN TELLE.
