    Specification* A.D. 1873.—N° 3964. Clarkson's Improvements in Securing Artificial Teeth. i In all cases to carry out this Invention with respect to preserving the natural shape of the teeth} the fastenings must he attached in such a position as to allow of the tooth being ground to any required extent in the process of fitting for the mouth. 5 The principle of this Invention may he applied to “ blocks ” as well as single teeth, the fastenings being secured to each side of the block. Any pattern of artificial tooth can be moulded and added to or cut away so as to adapt it to these fastenings, hut it is preferable to make the moulds from the natural teeth. 10 The design of this Invention is to imitate nature not only in the shape of the teeth but also in the manner of the connection. This will be seen by the Drawings representing the junction of the processes of the natural teeth, and the application of the fastenings used in this improve- • V t ment. 15 Teeth made according to this Invention may be used with frames or foundations when required for suction or other purposes; but such frames may be of considerable less thickness than usual; the required strength being obtained by means of the lateral unions. Variations of this method of securing teeth could easily be made* a 20 few such are represented in the Drawings. What is claimed as the Invention is the principle of employing lateral fastenings in imitation of the junction of the alveolar processes, thereby ensuring natural shape, solidity, and means of secure union in the articfical substitutes without necessarily employing [a foundation or frame, whether in the form of 25 plate, band, bar, or wire; the teeth being securely connected by the junction of the fastenings.
