Definitions

  • the invention relates to a post blank for a dental implant, which has an implant body for insertion into a jaw.
  • Dental jaw implants are widely known and serve to anchor dental restorations in the jaw of a patient.
  • such implants have an implant body, which often has a thread for screwing into the jaw, as well as a post on which the dental prosthesis can be fastened.
  • their posts are either rectilinear with a longitudinal axis of the Aligned implant body or are arranged angled to this at a certain angle of inclination, so that it is possible, the implant body - for example, if there is too little space in the vertical direction - obliquely screw into the jaw and still receive a vertically oriented post.
  • the post blank has an outer contour, which by an at least partially spatial overlay of the outer contour of at least one first single post, which includes a first inclination angle to a longitudinal axis of the implant body, and the outer contour of a second single post, to the longitudinal axis of the Implant body includes a second angle of inclination is formed.
  • a post blank is created in an advantageous manner, which is characterized in that from it by a simple material removal at least one post which extends either at the first or at the second inclination angle to the longitudinal axis of the implant body can be formed. It is therefore easily possible for the treating dentist or dental technician to machine the post blank on site in such a way that the post has the desired inclination to the longitudinal axis of the implant body.
  • An advantageous development of the invention provides that the outer contour of the post blank according to the invention by an at least partially spatial superposition of the outer contours of a plurality of individual posts whose inclination angle is in the limited by the first and second inclination angle range is formed.
  • the measure according to the invention has the advantage that from the post blank according to the invention not only a post, which extends either at the first inclination angle or at the second inclination angle inclined to the longitudinal axis of the implant body, can be formed. Rather, the measures according to the invention allow a post with a plurality of different angles of inclination to be formed from the post blank according to the invention.
  • a further advantageous development of the invention provides that the outer contour of the post blank according to the invention is set such that is transferred by a rotational movement of the first inclination angle extending first single post in the extending under the second inclination angle second single post.
  • Such a measure has the advantage that a post with an angle of inclination lying between the first and the second inclination angle can be created by a simple material removal of excess material areas from the post blank according to the invention.
  • a further advantageous development of the invention provides that the first inclination angle is substantially 0 °.
  • a further advantageous embodiment of the invention provides that the post blank and the implant body are integrally formed, which has the advantage of a compact implant with high strength.
  • a further advantageous embodiment of the invention provides that the post blank and the implant body are formed in two pieces and connectable to each other, whereby a lighter insertion of the implant body is possible.
  • the connection between the post blank and the implant body is secured against rotation, which is preferably realized by a non-rotationally symmetrical plug connection.
  • FIG. 1 shows a perspective oblique view of an exemplary embodiment of a post blank for a dental implant
  • FIG. 2 shows a perspective side view of the embodiment of FIG. 1,
  • FIG. 3 shows a cross section through the exemplary embodiment of FIG. 1 along a line III-III of FIG. 1,
  • FIG. 4 shows a plan view of the embodiment of FIG. 1
  • FIG. 5 shows a cross section through the exemplary embodiment of FIG. 1 connected to an implant body.
  • the post blank 1 has an outer contour A, which is defined by a superposition of an outer contour 2 1 of a first single post 2 and an outer contour 3 'of a second single post 3.
  • the above values of ⁇ i and c- 2 are only exemplary in nature. It is also possible to provide a smaller or larger inclination angle ⁇ i or ⁇ 2 .
  • the outer contour A of the post blank 1 is thus determined by a superposition of the outer contours 2 'and 3' of the two individual posts 2 and 3.
  • the post blank 1 removes that material which exceeds the shape of the desired angled post Y.
  • the post blank 1 furthermore has a gingival circulation stage 5, which displaces the gum on the implant body 6 when the post blank 1 is applied. It may have various embodiments known to those skilled in the art and, in cooperation with the implant body 6, serves to shape the gum and optimally apply it to the post blank 1.
  • the post blank 1 described in this embodiment has a two-part shape and, as shown in FIG. 5, is composed of a structural element 7 and a base element 8 which is preferably not machined.
  • the material of the structural element 7 is preferably zirconium oxide and that of the base element 8 is titanium, it being understood that it is also possible to use other materials, for example from the field of plastics, metals or ceramics.
  • the connection of the structural element 7 with the base element 8 can take place in a manner known to the person skilled in the art, for example by gluing, welding or shrinking.
  • connection of the post blank 1 or of the base element 8 with the implant body 6 shown here takes place via a projection 9 of the base element 8, which is introduced into a corresponding recess 10 of the implant body 6.
  • this compound is secured against rotation, for example by having a non-rotationally symmetric hexagonal cross-sectional shape.
  • Other shapes such as polygonal cross sections of recess 10 and projection 9 are of course also possible.
  • the post blank 1 has both in its structural element 7 and in the base element 8 via a passage 13, via which both the screw 11 can be inserted, as well as by means of a ge suitable tool with the internal thread 12 of the implant body 6 is screwed.
  • a one-piece post blank 1 is also possible.
  • implant body 6 of the post blank 1 and the implant body 6 are also made in one piece, which brings the advantage of higher strength with it, for example, a cross-section debilitating screw omitted.
  • a division in two makes it easier to insert the implant body 6 into the patient's jaw so that a choice of a one-piece or two-part implant can be made according to the desired advantages to be achieved.

Abstract

L'invention concerne une ébauche de tenon pour un implant dentaire, lequel implant présente un corps (6) prévu pour être inséré dans une mâchoire. Selon l'invention, l'ébauche de tenon (1) présente un contour extérieur, formé par une superposition au moins partiellement spatiale du contour extérieur d'au moins un premier tenon individuel (2), formant un premier angle d'inclinaison (a<SUB>1</SUB>) avec un axe longitudinal (B) du corps de l'implant, et du contour extérieur d'un second tenon individuel (3), formant un second angle d'inclinaison (a<SUB>2</SUB>) avec l'axe longitudinal (B) du corps (6) de l'implant.
