SPECIFICATION forming part of Letters Patent N 0. 354,833, dated December 21, 1886. Application filed March 30, 1886. Serial No. 197,124. (No model.)
To all whom. it may concern: groundconcave on the back, and are destitute Be it known that I, CHARLES P. GROUT, of of any metal pins, presenting a continuous the city and county of New York, in the State and unbroken porcelain surface, andlprovide 55 of New York, "have invented a new and useful for securing such porcelain faces or teeth on 5 Improvement in Artificial Tooth-Crowns and tooth-crowns without subjecting the porcelain Porcelain Faces therefor, of which the followfaces or teeth to the heat necessaryfo'r soldering is a specification. ing.
l/Vhen artificial tooth crowns or caps of gold, In the accompanying drawings, Figure 1 is 6 platinum, or other analogous metal are fitted a partly-sectional elevation of a tooth and a IO to teeth or tooth-roots which are visible when porcelain-faced crown secured thereon and worn in the mouth, such crowns or caps are made according to my invention. Fig. 2 is a usually provided with porcelain faces to simu horizontal section of the crown. Fig. 3 replate the appearance of the natural teeth. In resents the inner concave surface or back of 6 applying such porcelain faces to tooth-crowns the porcelain face or tooth, and Fig. 4. is a it is usual to apply to the porcelain face a gold horizontal section of the component parts of or other backing, which is soldered to pins the porcelain-faced crown separated from each.

In my Letters Patent N 0. 330,831, dated No- A designates the tooth, and B the gold or vember 17, 1885, I'have shown and described other metal crown applied thereto. a thin porcelain tooth-face ground concave on C designates the thin porcelain face or tooth, its inner face, so as to render the porcelain which is applied to the front of the crown to .face particularly adapted to crowns which are simulate a natural tooth. This tooth-face or 2 5 applied to teeth without much cutting away tooth is very thin, and is ground concave on of the tooth structure, as would be necessary the inner face or back. This porcelain face I if the tooth-crown were to have secured to it or tooth is destitute of any pins, and its inner a comparatively thick porcelain face or tooth face or back presents a continuous and un- 8 with a flat back, as is usually employed. The broken porcelain surface. The back of the porcelain face described in my aforesaid pattooth-face or tooth O is ground to a curve, to out had metal pins presented at its concave approximately fit the convex curvature of the back, and was backed with thin metal soldered crown B in a horizontal direction.

As here represented, the lip or 40 they show a blue color if platinum be used as flange 1) is formed by a thin plate, B, of gold,- a backing, and a yellow color if gold be used platinum, or other metal, which is soldered to as a backing, and no provision is afforded for the front of the crown B. The plate Bis first applying immediately behind the tooth-face a burnished down to fit the concave back of the 95 white cement or other composition or matetooth or tooth-face O, and its edge or margin is rial which will cause the porcelain face to turned slightly outward to form the lip or show white like the natural teeth, and which flange b. The plate B (best shown in Fig. 4) will absolutely and perfectly fill all minute is then soldered to the crown B, and at any spaces behind the tooth-face and between it convenient time thereafter the porcelain tooth: 1 and the metal, and prevent the entrance of all face or tooth C may be inserted within the lip secretions behind the porcelain tooth-face. Or flange band thelatter burnished down over In carrying out my invention I make thin the edge thereof, in order to secure it firmly porcelain tooth faces orteeth, which are in place.
From the above description it will be understood that all heating and soldering together of parts of the crown is done before the porcelain face is combined therewith, and hence the latter will never be cracked by the flux used in soldering. This method of securing the porcelain face to the crown B also provides for introducing a small quantity of liquid gntta-percha, oxyphosphate of zinc, or other composition behind the tooth-face or tooth, in order to simulate the natural appearance and color of a tooth, and prevent the color of the metal from showing through the toothface or tooth.
It is not indispensable to my invention, so far as the combination of the tooth-face with the crown is concerned, that the tooth-face should be destitute of pins at the back, because a tooth-face having pins presented at the back, but having no projection, might be used. The pins would'not, however, serve any useful purpose, and would be a detriment to the porcelain face.
What I claim as my invention, and desire to secure by Letters Patent, i's- 1. The combination, with a metallic toothcrown provided at the front with a flange or lip, of a porcelain face fitting the front of the crown within the flange or lip and secured in place by turning the flange'or lip inward over its edge or margin, substantially as herein described.
2. The combination, with a metallic toothcrown, of a curved plate soldered to the front of the crown and having its edge portion turned outward to form a lip or flange, b, and a porcelain tooth-face secured on the front of the crown by the turning inward of the lip or flange I) over its edge, substantially as herein described.
CHAS. P. GROUT.
