    N° 24,585 Date of Application, 3rd Nov., 1896—Accepted, 3rd Jan., 1898 COMPLETE SPECIFICATION. Improvements in the Manufacture of Artificial Teeth. I, Antonio Villar, of Valladolid in the Kingdom of Spain, Dentist, do hereby declare the nature of this invention and in what manner the same is to be performed to be particularly described and ascertained in and by the following statement:— 5 This invention relates to the manufacture of Artificial teeth. Among the many infirmities afflicting the human race those of the teeth occupy a prominent place, owing to the frequency with which they occur as well as to the pain the patient suffers therefrom. Numerous means have been tried in all ages to cure these ills, among which the 10 most radical has always been the extracting of the affected teeth, a violent measure and one which, although eradicating pain, also destroys a very necessary adjunct to the preservation of health and moreover prejudicially affects the appearance. To remedy such evils Dental Prothesis was established with the object of replacing the lost teeth by artificial ones, employing first of all human teeth, then teeth of 15 animals and lastly mineral or incorruptible ones, made of porcelain, which cannot be improved upon as regards the nature of their composition but as regards their shape and form they may differ from those hitherto known. The only substances employed for my crown-tooth are porcelain, which is used for the manufacture of all sorts of artificial teeth, and platinum which is the only material 20 capable of being embodied with porcelain. My improved teeth consist of a front and a back face, side faces and a base. The front face is merely made of porcelain thus precluding any metallic ring being seen when setting the tooth, which is not the case with other crown-teeth. The side faces, also consisting of porcelain, serve, together with the inner edge of 25 the body of the tooth, to allow of the insertion of a stationary platinum sheet or plate which constitutes the back face and base of the crown-tooth. The base is hollow or concave and fluted in the inner portion of its front face with the view of making the tooth lighter and more adhesive when used in vulcanite working. 30 The object of my invention is to provide a tooth which when manufactured shall be ready for use as a plane tooth as a crown-tooth and for the so called bridge-work, thus avoiding in all cases counter-plating and such other operations as are indispen¬ sable for converting a plane tooth into a crown. Now, inasmuch as this attribute of my new system enables a great deal of time and work to be saved there having been 35 heretofore no tooth which could be used either with a base plate on vulcanite or as a crown, and, as the essential and peculiar characteristic of my tooth apart from its form, consists in the platinum plate which is flanged at its lower end and is fixed to the body thereof, its purpose being to allow of one tooth being welded to another without its being submitted to any other process than the manufacturing one, 40 the result of all the above will be that not only on account of its form but also because of its many and ready applications, my crown-tooth will prove a useful novelty.
