    Provisional Clarksons Improvements in Securing Artificial Teeth. The methods or means hitherto generally adopted for inserting and securing artificial teeth consist in inserting and securing them either on the roots of the natural teeth by means of a pivot or pin running up or into the root, or such teeth are fixed on or attached to a metallic or vulcanite base or frame forming a foundation on which to secure the 5 artificial teeth. The pins or platina fastenings for connecting and securing such teeth have hitherto been placed and fitted so as to run right up a hole in the centre of what are called “ tube ” teeth, and are soldered to the foundation frame or palate, the pins being held in their positions in the teeth by 10 means of sulphur or mastic. The disadvantage of this method of securing artificial teeth is that where the “ bite ” is closed and the tooth consequently short, thereby allowing very little length for the pin or pins, they are very liable to come off or to break. As hitherto practised in flat mineral teeth (so 15 called from the back of the teeth being quite flat, the front teeth being only half teeth, and the back part not bearing the least resemblance to natural teeth), in each tooth two platina pins or rivets are usually inserted in a horizontal position in the backs for the purpose of securing them to the artificial frame or plate. 20 In vulcanite “ pin ” teeth generally used in the best description of vulcanite work, they, like the “ flat ” teeth, have two pins inserted in the back of each tooth to secure them to the vulcanite foundation or plate, the disadvantage of this system being that the pins or rivets in the backs of the teeth prevent them from being hollowed out in a natural 25 manner. This Invention has therefore been designed to remedy the above named disadvantages or defects, and it consists in forming or making artificial teeth with a lateral hole through each tooth through which hole a platina pin or fastening (made of the desired shape and size) is 80 passed and secured to the side or lateral slope or angle of the tooth (or teeth), and not to the back part or up the centre of the tooth as hitherto. The chief advantages of these improved means of fastening and connecting artificial teeth will be that the platina pins or fastenings of 35 each tooth can if desired be easily connected or soldered laterally to those of the next and so on through the entire set, thus affording more strength
