Definitions

  • Dental plates are known for the application of artificial teeth, which are normally immovable when seat in a bone-like fitting.
  • the improvement in accordance with the present invention concerns the process for forming the tooth head or top which connects with the pivot, as a support element of the artificial teeth. Such a process makes it possible not only to provide an immovable top relatively to its support pin but also to form an anatomically correct top by the use of a punch cooperating with a counter punch designed and constructed for that purpose.
  • the present invention makes it possible to form the head or top with an angular orientation of its axis, relatively to the orientation of the axis of the support pin and therefore relatively to the root belonging to the Patient. It will therefore be possible, even if the root has anomalies in location, to adapt the inclination of the axis of the top to the inclination of the axis of the root of the natural tooth or at least to adjust it for purposes of appearance with regard to the alignment of the teeth.
  • FIG. 1 shows a cylinder from which a tooth blank is formed
  • FIG. 2a is an elevation of the tooth blank
  • FIG. 2b is a part section of an alternative tooth blank
  • FIG. 3 is a section of the tooth blank mounted in a counter punch with associated punch
  • FIG. 4 is a section of the parts of FIG. 3 in the closed position
  • FIG. 5a is a side elevation
  • FIG. 5b is a front elevation of a punch formed tooth
  • FIGS. 6a, 6b and 6c show teeth punched with alternative inclinations and FIG. 6d is a plan view of a punched tooth.
  • FIG. 1 shows a cylinder of suitable material having a high strength, from which, according to sections a-B there is hollowed out mechanically a piece shown in FIG. 2a and formed of the following components: a truncated conical pivot 1 carrying below the groove 2 and connected at its upper end with a projecting collar 3 and an upper head 4 of frusto conical formation.
  • FIG. 3 shows at the top a counter punch, hollow and preferably cylindrical, within the cavity of which a core 6 having slightly conical outer surfaces is introduced under pressure; the lower end of the core carries a frusto conical member, the shape of which matches that of the parts 1, 2 and 3 of the piece shown in FIG. 2a.
  • the core 6 comprises a seat 8 within which may be rotated an eccentric 9 hinged on a transverse pivot 10 located in a seat formed in the two members forming the counter punch, namely, the core 6 and the hollow cylinder 5.
  • the eccentric By operating the handle 11 the eccentric may be employed to extract the pins 1, 2., 3 of the said piece shown in FIG. 2a when the operation of stamping out the head has been effected as will be described hereinafter.
  • the punch 12 which has on its upper surface 13 a cavity 14 formed according to the shape of the tooth which will be located at a suitable incline, according to the anatomical requirements of the subject as being the most suitable for the good execution of the work.
  • FIGS. 5a and 5b respectively show the side and front of a component pieces produced according to the described process, the head 4 of which is covered, with the interposition of cementing material 15, by a coat 16 of an enamel-like substance.
  • FIGS. 6a, 6b, 60 show side views of a three component piece formed according to various required anatomical inclinations.
  • FIG. 6a show the vertices can be removed from their respective heads 4 according to the process of the invention; for example with axis y-y of the pin the tip is disposed forwardly at 17 in FIG. 6a or disposed thereon as shown in 17' in FIG. 6b or held as shown in 17" in FIG. 6c.
  • FIG. 60 shows in part cross section a variation of construction of the component shown in FIG. 2a wherein the head 4' with the collar 3' is screwed on the support pin 1' which then is hollowed out by turning.
  • the heads of the components shown are formed according to the process described any may be hollowed out in the course of the preparatory work in the laboratory so as to have readily available means to produce intermediate elements to be located among elements of the type stated in the described process for the purpose of completing dentures having an immobile bridge.
  • a tooth forming moldable member having a frusto conical body and a pin connected to the wider end of said frusto conical body.
  • a counter punch a member having a pin carried by said counter punch and a tooth forming moldable piece connected with said pin and projecting outwardly from said counter punch, and a punch having a cavity adapted to receive said tooth forming piece, said cavity having the shape of an artificial tooth.
