It consists of one on a tooth stump or an abutment of an implant attachable primary crown, further from a provided in the dental prosthesis, can be placed on the primary crown secondary crown. Between the primary crown and the secondary crown a spacer crown is provided, which is either firmly connected to the primary and secondary crown or is in frictional connection with at least one of these two crowns.
  • DE 10 2008 058 305 A1 discloses a connecting device for fastening a dental prosthesis to a jawbone with at least two connecting elements, each of which has an implant to be inserted into a jawbone and a male part extending from the implant along a male axis for connection to a dental Have prosthesis. It is provided that the Patrizenachsen, along which extend the male of the at least two connecting elements arranged in a jaw bone connecting elements, substantially parallel to each other.
  • this document describes another connection device and a method for producing a connection device for fastening a dental prosthesis to a jawbone.

  • a fastening device for a dental prosthesis in particular for use with a plurality of implants in the mouth of a patient is given, which has a lower part, which is connectable along a first axis with an implant and has a second axis arranged on a holding element, which of an upper part is enclosed, wherein the upper part is suitable for connection to a dental prosthesis, wherein between the upper part and lower part of an adhesive gap is formed, which allows for introduction of an adhesive material balancing between the upper part and lower part.
  • the fastening device thus provides a possibility for compensating the position between a tooth surface assigned to the upper part. prosthesis and one or more the lower part associated implant or implants to create.
  • the adhesive gap thus serves to correct positional inaccuracies when setting the implant (s) or manufacturing tolerances in the production of the required parts.
  • the lower part can be prefabricated with respect to the geometric configuration such as angulation or shaping in the region of the gingiva and individually generated for each patient, for example by means of a CAD / CAM method.
  • any deviations can be compensated via the adhesive gap, so that the dental prosthesis can be brought onto the implants by means of the fastening device according to the invention, without exerting mechanical forces acting in particular in the radial direction, which could hinder the osseointegration of the implants.
  • the upper part can completely or even partially enclose the lower part.
  • the adhesive gap between the upper part and the lower part has a drainage channel.
  • the drainage channel can thus be used to dispense excess adhesive material, which in particular facilitates the use of the fastening device according to the invention, since no precise application of the adhesive material with a predetermined volume is required.
  • the adhesive gap completely or at least partially covers the retaining element.
  • both a stable attachment of the dental prosthesis to the implant or implants can be achieved as well as a seal of the upper part against the lower part to prevent deposits reach.
  • the first axis and the second axis at an angle to each other.
  • the angulation of the fastening device can be selected individually, so that an orientation of the first axis to the second axis adapted to the oral situation can be selected.
  • the first axis and the second axis have a same orientation.
  • the fastening device according to the invention can also be used in straight-shaped lower parts, are oriented in the holding element and implant in the same direction.
  • angulated and non-angulated embodiments can also be chosen differently for different implant positions.
  • the upper part has an opening arranged on the top, which is provided with an internal thread into which a draw-off screw along the second axis can be introduced.
  • the lower part is designed as an abutment.
  • the lower part can be adapted to different implants in order to create compatibility with different implant designs.
  • the lower part is prefabricated on a patient-specific basis.
  • the lower part may in particular be subject to angulation, i. the angle between the first and the second axis, and / or be prefabricated in the region of the gingival transition to the gingival formation for the respective oral situation at the intended implant position, so that the best possible patient-individual use is possible.
  • the upper part is connectable with a cap which is suitable for receiving a dental prosthesis.
  • the cap can be releasably secured to the upper part by any type of connection known from the prior art.
  • any type of connection known from the prior art.
  • a further adhesive gap is formed between the cap and the dental prosthesis. Any deviations can be compensated for via the adhesive gap alone or in combination with the further adhesive gap or even alone by the further adhesive gap, so that the dental prosthesis can be brought to the implants by means of the fastening device according to the invention without mechanical forces.
  • FIG. 1 shows a fastening device according to the invention in a sectional view
  • Fig. 2 shows another fastening device according to the invention in one
  • Fig. 3 shows a further fastening device according to the invention in one
  • a first embodiment of a fastening device according to the invention BV is shown in a sectional view.
  • the fastening device BV has a lower part UT, which has at its lower end a rotationally symmetrical about a first axis EA receiving element AE, which consists of a mounting channel for receiving a fastening screw is penetrated.
  • the receiving element can for example be inserted into an implant (not shown in FIG. 1) and secured in the fastening channel BK by means of a screw, not shown.
  • a holding element HE is formed, which has a frustoconical construction except for the region which is penetrated by the fastening channel BK.
  • the lower part UT thus represents an individually adapted abutment, which can be introduced into an implant.
  • the adhesive gap KS is also formed in the region below the lower end of the upper part OT, so that excess adhesive can be dissipated in the adhesive gap KS to the outside.
  • a special outflow channel AK as indicated in FIG. 1. 2
  • the upper part OT here has an opening delimited by an internal thread IG, through which a take-off screw AS constructed as a set screw is guided.
  • the withdrawal screw AS is thereby introduced to separate the upper part OT from the lower part UT with its external thread AG along the second axis ZA further into the internal thread IG, so that this, as soon as it comes into contact with the holding element HE causes a withdrawal force, so that the Upper part OT can be detached from lower part UT.
  • the withdrawal screw AS can be supported on the upper side of the retaining element HE.
  • the upper side of the upper part OT can form a flat surface with the upper side of the withdrawal screw AS until use of the trigger function.
  • the lower part UT can be removed from the implant by loosening a screw in the fastening channel BK, so that it is now accessible.
  • the overcoming of the holding force of the adhesive material in the adhesive gap KS is possible by means of a trigger screw AS, without applying forces that would predominantly act in the radial direction on the implant, so that the ingrowth of the implants in the jawbone would be difficult.

  • a further adhesive gap WK is provided between cap KA and upper part OT.
  • the adhesive gap KS between upper part OT and lower part UT can also be selected with a smaller distance, since now also the further adhesive gap WK is available for compensation.
  • the fastening device BV according to the invention is particularly suitable for the use of freshly placed implants, since an adaptation to the individual situation of a patient is possible by means of the adhesive gap KS or of the further adhesive gap WK. Accordingly, lower parts can be individually produced as abutments at the respective implant positions individually for each patient, for example by means of a CAD / CAM method. Possible deviations can be compensated for via the adhesive gap KS alone or in combination with the further adhesive gap WK or even alone by the further adhesive gap WK, so that the dental prosthesis can be brought to the implants by means of the fastening device BV according to the invention without mechanical forces.
  • the dimensioning of the glue gap KS can be carried out in such a way that deviations of a few degrees (in 3 °) can be compensated. With regard to the dimensioning of the additional adhesive gap WK greater compensation is possible.
