Definitions

  • the invention relates to a dental implant system comprising an implant and at least two abutments, wherein at least one of the abutments is seated with a recess on a head part of the implant corresponding to the recess.
  • the implant For the prosthetic replacement of individual teeth, it is known to replace the completely missing tooth in the jaw with an implant that is anchored in the Kiefenknochen.
  • the implant thus has an endosseous part, whose extension bumps through the gingiva and thus causes an opening of the body.
  • the endosseous part of the implant Before an inserted implant can be loaded with a chewing force, it is necessary for the endosseous part of the implant to heal in and be firmly enclosed by the bone substance.
  • the neck of an implant which is present in the inserted state of the implant at the level of the gingiva, polished so as not to irritate the vital and soft tissue of the gingiva as possible, because the gingiva encloses after healing the implant and protects the underlying tissue Penetration of foreign bodies and microbes.
  • a provisional is placed on the head of the implant, which is not in occlusion with an antagonist, so as not to disturb the healing process. Only after the implant has healed can it be fully loaded and an abutment in the form of a tooth blank or a prosthetics manufactured in the technical center is placed on the neck area of the implant as a full dental prosthesis.
  • the optimal height of the head portion of the implant protruding from the gingiva is difficult to assess and may change slightly during the healing process. Therefore, when a prefabricated abutment is placed on the healed implant, it may happen that in the patient's smile line the neck of the tooth can be undesirably recognized as an implant or the abutment presses on the gingiva as the mucosal height across the jawbone varies with each patient is. In order to take into account the individual mucosal height of the patient, the abutment is shortened accordingly when inserting. However, adjusting the patient's mouth requires one

  • Implant system consisting of an implant and an abutment.
  • the abutment has a conical opening with which it rests on the truncated conical implant head.
  • To prevent the abutment from twisting on the implant it is provided that has an elevation in the conical opening, which engages in a groove of the implant head and thus forms a locking element.
  • This implant system has the above-mentioned disadvantage that the height of the abutment shaft is not necessarily adapted to the mucosal height of the patient and may need to be prepared when fitting in the mouth of the patient, so that the gingiva is not traumatized.
  • the object of the invention is therefore to provide an implant system available, which can be adapted to the individual mucosal height easier and faster.
  • the object of the invention is achieved in that the at least two abutments have differently shaped recesses, whereby the at least two abutments seated at different heights on the head part of the implant. Further advantageous embodiments of the invention are specified in the subclaims.
  • the dental implant system consists of at least one implant and at least two abutments, the abutments having differently shaped recesses or openings. Because these recesses or openings are designed differently, they sit with a different height on the implant.

  • the multi-edge system can be a square, six or octagonal system. Other systems for transmitting torque from a tool to the implant are also possible.

Abstract

L'invention concerne un système d'implant dentaire comprenant un implant et au moins deux butées. Dans ce cade, au moins l'une des butées repose avec une cavité sur une partie tête de l'implant correspondant à la cavité. Au moins deux butées comportent des cavités configurées de manière différente, grâce auxquelles les deux butées ou plus reposent sur la partie tête de l'implant à des hauteurs différentes.
