Definitions

  • the present invention concerns a dental installation inter ⁇ nal to its bone, comprising an external elastic coating to the metal structure of said installation.
  • a natural tooth when subject to those pressures perform ⁇ ed thereon during the natural mastication function, shows an intrusion of about 0.1 mm, due to the paradontal li ⁇ gament.
  • the dental installation internal to its bone that is the object of the present invention, comprises - for simulat ⁇ ing the function of the paradontal ligament - an external elastic coating which, once it has obtained strong links with the alveolar bone or by means of interposition of a bone-integrating matrix , makes possible the intrusion of the installation in a way similar to the one of the natu ⁇ ral tooth, as well as the determination of tension forces for the alveolar bone.
  • the present invention also solves the prob ⁇ lem of the different intrusive elasticity existing bet ⁇ ween a natural tooth and an installation internal to the bone, being fix (not elastic), being part of one and the same dental prosthesis.
  • the installa ⁇ tion according to the present invention has the purpose of simulating the behaviour the the natural tooth also during the mastication function.
  • figure 1 shows a vertical section of a dental installa ⁇ tion internal to its bone
  • figure 2 shows a possible variant of the installation ac ⁇ cording to the present invention having the same purpose
  • figure 3 shows a detail of a portion of the installation according to the present invention.
