Definitions

  • the present invention relates to medicine, namely to surgical and orthopedic dentistry in dental implantation.
  • An implant is an artificial tooth root, most often made of medical pure titanium (BT 1-00). Through surgery, the implant is implanted in the jawbone. After implantation, the implant is used as the main support to restore lost chewing function.
  • BT 1-00 medical pure titanium
  • the implant is inserted into the jawbone, both by open access, that is, by folding the mucosal-periosteal flap, and by closed access, using a mucotome, form an opening on the mucous membrane of the alveolar bone corresponding to the diameter of the implant.
  • a bed is formed in the jawbone for implant placement.
  • a necessary condition for achieving the predicted result during dental implantation is the condition of the soft tissues surrounding the implant.
  • Implantation takes a long time, on average, from three to six months.
  • an orthopedic design is installed on it.
  • the dental implant has intraosseous and supragingival parts.
  • the intraosseous part is implanted in the patient’s jaw bone.
  • Gingival part protrudes from the jawbone and gums and is designed to attach an orthopedic structure.
  • plate implants are used.
  • a plate implant is an implant, the intraosseous part of which is in the form of a plate.
  • One embodiment of a plate implant is described in patent RU 2139010.
  • a plate implant may have several through holes.
  • bone tissue is restored and fixes the implant.
  • bone tissue grows through the through holes in the implant, thereby providing additional fixation of the implant.
  • Cylindrical root implants are implants of the intraosseous part of which has the shape of a cylinder. In the process of implantation of a cylindrical implant, bone tissue is restored and fixes the implant.
  • a cylindrical implant may also have several openings. During restoration, bone tissue grows through the through holes in the implant, thereby providing additional fixation of the implant.
  • plate implants The disadvantage of plate implants is the increased invasiveness of surgical interventions. In addition, when using plate implants, it is necessary to connect the implant with intact teeth.
  • An additional disadvantage of lamellar and cylindrical implants having through holes is that if it is necessary to remove the implant after restoration of the bone tissue of the jaw, traumatic removal of bone tissue together with the implant will be required. Removing one implant without surrounding bone tissue is not possible.
  • a cylindrical implant that does not have through holes and any means of preventing rotation can rotate about its axis when using early functional loads. This is also a disadvantage.
  • Root-shaped implants of helical form are implants of the intraosseous part of which has the shape of a cylinder and is equipped with an external thread.
  • FIG. 1 is a schematic illustration of the intraosseous portion of a screw implant.
  • the screw implant 1 contains an external thread 2.
  • a hole is drilled corresponding to the cylindrical part 4 of the screw implant 1.
  • the size of the hole in the bone 3 of the jaw is smaller than the external size of the thread 2 of the implant 1.
  • the screw implant 1 is installed by screwing it into the bone tissue.
  • the cylindrical part 4 is freely placed inside the hole in the bone tissue, and the external thread 2 is in contact with the inner surface of the hole, namely, it cuts into the bone tissue.
  • the result is the fixation of the screw implant 1 inside the bone tissue 3 of the jaw at the time of installation of the implant.
  • a screw implant can be equipped with anti-rotation grooves 5.
  • bone tissue grows into anti-rotation grooves 5.
  • Screw implants provide fixation of the implant from the moment of installation. This ensures the primary stability of the implant.
  • the disadvantages of screw implants include the following.
  • the external thread 2 interacts with the bone tissue, namely, cuts into it and forms a mating internal thread on the inner surface of the hole in the bone tissue of the jaw.
  • Figure 1 shows the area 6 of bone tissue undergoing necrosis.
  • the implant 1 can be shifted relative to its original position.
  • Screw implants Due to necrosis of part of the bone tissue, the implantation time of the screw implant is increased and the likelihood of rejection is increased. In addition, the range of application of screw implants is limited. Screw implants are not used for dental prosthetics in narrow places of the jaw and atrophied places of the jaw. This restriction is caused by the possibility of destruction of the jaw bone when installing a screw implant as a result of external threading.
  • One-stage implants are implants in which the intraosseous part and the supragingival part are made as a whole, that is, as a single product.
  • the supragingival part of the implant is exposed to external forces that are transmitted to the intraosseous part.
  • the implant may move relative to its original position.
  • Two-stage implants are implants in which the intraosseous part and the supragingival part are made separately, that is, in the form of two products.
  • the intraosseous part and the supragingival part of the two-stage implant are connected using a threaded connection.
  • the supragingival part of the implant is attached to the intraosseous only after implantation of the intraosseous part of the implant, that is, after complete restoration of the bone tissue of the jaw.

Abstract

L'invention concerne la médecine et, plus particulièrement, la chirurgie dentaire et la stomatologie orthopédique. Selon la présente invention, un implant dentaire comprend une partie principale en forme de tige et au moins une arête d'ancrage qui est formée sur la partie principale et est conçue pour avoir une interaction avec le tissu osseux lorsque l'implant est installé. L'orientation de l'arête d'ancrage coïncide sensiblement avec l'orientation de l'axe de la partie principale. Grâce à ce type d'implant, il est possible d'écourter le temps d'implantation et de réduire les risques de rejet de l'implant.
