Application filed December 5, 1921.
To all whom it may concern Be it known that I, HOUSTON M. CARROLL, Sn, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Compression Tray, of which the following is a specification.
As it is well understood by persons skilled in the art, plaster of Paris, contained in an impression cup is frequently used for taking impressions of the human mouth, in connec tion with the operation of fashioning artificial teeth. Further, it is well known that the palatine arch is much harder and unyielding than is the alveolar ridge. The result is that when a bite is taken on a mass of plaster of Paris, or the like, in an impression tray, the water is pressed out of the central portion of the mass, by the relatively hard palatine arch, and flows to the ed es of the tray, thereby softening the material in which the impression of the alveolar ridge is received. The unsatisfactory results flowing from the foregoing operation will be appreciated readily.
In view of the foregoing, this invention aims, broadly considered, to provide an impression tray, the central portion of which is more yielding than is the peripheral portion thereof, to the end that the palatine arch may not compress the water out of the mixture, thereby softening that portion of the mixture wherein the impression of the alveolar ridge is received.
Itis within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.
In the accompanying drawings:
Figure 1 shows in top plan, a tray constructed in accordance with the invention; Figure 2 is a bottom plan of the tray Figure 3 is a section on the line 33 of Figure 1; Figure 4 is a section on the line 44 of Figure 1; and Figure 5 is an enlarged section on the line 55 of Figure 1.
In carrying out the invention, there is provided a main member 1 which may be made of metal or any other relatively rigid substance, the main member including a base 2 having an opening 3, the main member being supplied with an upstanding marginal Specification of Letters Patent.
Patented Jan. 24, 1922.
Serial No. 520,037.
A yieldable and preferably resilient diaphragm 9 is located between the base 2 of the main member 1 and the auxiliary member 5. The diaphragm 9 may be made of rubber or any other suitable material having the physical characteristics above alluded to. Securing elements 10 connect the auxiliary member 5 with the main member 1 and hold the diaphragm 9 in place. The securing elements 10 preferably are removable, to the end that the diaphragm 9 may be renewed, and, if preferred, screws may be used.
When a bite is taken, that portion of the impression material which is compressed by the relatively hard palatine arch will cause the diaphragm 9 to yield, practically none of the water being squeezed out of the impres sion material to moisten or liquefy that portion of the impression material which receives the impression of the alveolar ridge. The impression material retains its homogeneity, and the clearness of the impression is preserved, especially as regards the alveolar ridge.
What is claimed is:
1. A dental impression tray embodying a. marginal portion, and an inner portion which is more yielding than the marginal portion.
2. A dental impression tray comprising a main member having an opening; and a yieldable diaphragm secured to the main member and extended across the opening.
3. A dental impression tray comprising main and auxiliary members having registering openings; and a yieldable diaphragm held between said members and extended across the'openings.
4. A dental impression tray comprising main and auxiliary members having regis- I tering openings, the auxiliary member being In testimony that I cleim the foregoing prolonged to form a handle for the tray; a as my OWI1,-I have hereto 'afiixed my signayieldable diaphragm located between the tune 1n the resence of twp itnesses. 7 main and auxiliary members :and extended H iUSTON 1W; CARROLL; f SRi across the openings; and means fer connect- WitneSses'i ing the main and auxiliary members releas- J P.
