ARTIFICIAL TEETH.

To all whom it may concern:

Be it known that I, MIGUEL LINARES, a subject of the King of Spain, residing in the city of Alcoy, Province of Alicante, Spain, have invented certain new and useful Improvements in Artificial Teeth, of which th following is a specification.

This invention relates to improvements in artificial dentures of the kind having a small seating or support. The hygienic benefits of a small seating are obvious, and the wearer would find it more comfortable if it could be held in position as securely as a large seating.

The object of thefpresent invention is to provide improved means for holding such a denture satisfactorily in position by suction.

The invention comprises an'artificial clentur provided witha movable piston adapted when pressed to expel air from between the seating of the denture andthe gum on which it'rests. located in place of one of the artificial teeth.

A construction according to this invention is illustrated in the accompanying drawing in which:

Figure 1 is a perspective view of the suction side of an upper denture; Fig. 2 is a perspective upper view of a lower denture; Fig. 3 is a section on an enlarged scale through the line 3, 3, in Fig. 1, and Fig. 1 is a section on an enlarged scale through the line 4, a, in Fig. .1.

Both the upper and the lower dentures comprise 14 teeth, 12 of porcelain and two piston crowns at, J which latter form the suction devices, each acting, through a hole J which opens on tothe suction surface of the seating H. 40;

Referring to Figs. 3. and 4, A is a piston preferably about 0.4 mmathick adapted to slide in the casing B mounted in the seating H and held in the usual manner by roughening the outer surface or by providing projections to engage the seating material. Secured within the piston are two strips of metal E which pass freely through a support O mounted in the seating H as shown in Fig.

3, the strips E being bent over at the ends to prevent the piston from being forced out of Specification of Letters Patent. 7

the casing B by the spring D which holds the piston normally in its outer position. The parts gold, platinum, iridium platinum alloy, or other suitable metal. The head of the piston serves as the entire crown. When the mouth is closed for mastication or articulation, the spring is compressed because the piston crowns engage the opposite denture, and thus the air is expelled from between the seating and the gum on which it rests, there by producing suction when the spring ex pands. The stroke of the piston is approximately 5 to 1 mm. but of course this may be varied- It will be seen that the position of the molars on each side, corresponds with the vacuum chamber of oval shape where the A, B, C, I), E, may be of 18 carat suction device acts. Any one of the four molars situated at each side of the denture can be used for the suction device.

What I claim is:

1. In an artificial denture, a seating to engage the tissue of the mouth and provided with an air passage extending through from the suction surface of the seating to'the opposite face of the denture, and a suction device located in the air passage and adapted when pressed to expel air from between the seating of the denture and the tissue on which it rests.

2. In an artificial denture, a seating to engage the tissue ofthe mouth and provided with an air passage, and a piston crown located in the air passage in the position molar tooth and adapted when pressed to exofa pel air from between the seating of the dengage the tissue of the mouth and provided with an air passage, a piston and lining located in the air passage inthe position of a molar tooth and adapted when pressed to expel air from between the seating of the denture and the tissue on which it rests, and a spring to normally hold the piston in its outer position.

4:. In an artificial denture, a seating to engage the tissue of the mouth and provided with an air passage, a cylindrical lining in said passage in the position of a molar, a
