This invention relates to dental appliof still another modification, especially of ances, and more particularly to an arrangethe suction plate. ment for sucking off secretions which may Referring to Fig. 1, the upper jaw is have collected in dental canals.

The suction conduit comprises the india rubber tube 8 with its inserted coil spring,.andcommunication between this tube and the tooth socket is established -by means of a screw threaded mouth piece 17, preferably made of iron and arranged to be screwed up and down within the yoke or stirrup 19, which, for this purpose, is provided with a corresponding screw thread at its centre. At its lower end the said mouthpiece terminates into a loose section of suction tube 21, attached to the mouth piece 17 by means of a The purpose of this loose piece of tubing is to enable a better insertion of the appliance into the hole 4 made by the dentist. V

In order to provide an airtight joint with the tooth, the tube 21 is provided with a fiat suction pad 22 made of'india rubber or the like material, and which pressed tightly upon the tooth when the mouth piece 17 is screwed down in the stirrup 19 Fixing .the stirrup upon the crown of the tooth is etfected by means of clips without the tooth being pressed thereby in the direction of its root. The said clips are pivoted tothe stirrup at 23 and are 'aoapted, with their jaws 24, to bear sideways upon the tooth by means of the set screws 28 having preferably milled heads 27, The stirrupll), in this way, forms a support for the mouthpiece 17 While the latter being pressed onto the tooth; the pressure being directly taken up by the jaws 2st; it is not transmitted to the root of thetooth or to the pa-tients jaw.

The modification shown in Figs. 4- and 5 (litters from the aforesaid only in that the firing jaws are provided with pads 23 for the" purpose o1 preventing the tooth being clamped by the metallic parts of the appliance.
