Definitions

  • This invention pertains in general to the field of a implant arrangement, and in particular to a platform switch for implant arrangements. More particularly the invention relates an adapter, such as a dental implant platform switch, for attachment to a dental implant, said adapter comprising a threaded part for connection with a dental implant and a conical male part, corresponding to a conical connection surface of a female part in an implant with a conical connection platform.
  • an adapter such as a dental implant platform switch
  • Conical Seal DesignTM is a conical connection below the marginal bone level that transfers the load deeper down in the bone.
  • Conical Seal DesignTM reduces peak stresses and thereby preserves the marginal bone. It also seals off the interior of the implant from surrounding tissues, minimizing micro-movements and micro-leakage.
  • Conical Seal DesignTM simplifies maintenance and ensures reliability in all clinical situations.
  • the tight and precisely fitting implant-abutment relation of the Conical Seal DesignTM makes abutment connection a quick and simple procedure. The abutment is self-guiding and the installation procedure is non-traumatic, eliminating the risk of bone damage.
  • Conical Seal DesignTM is first implanted in the jaw bone of the patient, where after a spacer element is attached to the Conical Seal DesignTM.
  • This spacer element is in this context provided with a threaded part, to be threadingly connected to the implant, and a conical male part, adapted to bear on the conical connection platform of the implant.
  • the spacer element is provided with an abutment, extending upwards from the dental implant, constituting a mounting knob in the oral cavity of the patient. Thereafter, a dental superstructure may be mounted on the abutment of the spacer element.
  • Conical Seal DesignTM results in a need of spacer elements according to above, whereupon the application of a superstructure will be in a distance level in respect of the implant.
  • US 6,168,436 discloses a universal dental implant abutment system, comprising an abutment collar and a fixation screw.
  • the abutment collar has a cylindrical part for cooperation with an implant body.
  • the system disclosed in US 6,168,436 does not convert the platform of the dental implant.
  • the present invention preferably seeks to mitigate, alleviate or eliminate one or more of the above-identified deficiencies in the art and disadvantages singly or in any combination and solves at least the above mentioned problems by providing an adapter for a dental implant with a conical connection recess in its upper part, said adapter comprising a threaded part for connection with said dental implant and a conical main body, corresponding to a conical connection recess of said implant, a tool grip portion, allowing for attachment of said adapter to said implant by the aid of a tool, and a connection recess adapted for connection to a spacer element or a dental structure.
  • Fig. 1 is a side contour view of an adapter according to one embodiment of the present invention.
  • Figs. 2a and 2b are end views of adapters according to embodiments of the present invention.
  • an adapter according to Fig. 1, is provided.
  • This adapter comprises a main body 11 and a threaded male part 12.
  • the threaded male part 12 is adapted to be threadingly fitted with a threaded female part of an implant.
  • the main body 11 has a first end connected to the threaded male part 12 and a second end located on a distance from said first end along a central axis of the adapter.
  • a connection recess 13 and a tool grip portion 14 are located in said second end of the adapter.
  • the connection recess 13 and the tool grip portion 14 may preferably also be aligned along the central axis of the adapter.
  • the tool grip portion 14 may suitable be a in the form of a screwdriver slot or an internal hexagonal fitting, of known type to the skilled artisan, in the bottom of the connection recess 13.
  • the connection recess 13 may comprise a threaded female part 15, stretching from the end of the tool grip portion 14 towards the second end of the adapter.
  • the tool grip portion 14 allows a tool, such as a screwdriver, to engage with the adapter to fasten it to the dental implant.
  • the female threaded part 15 allows a screw member to be threadingly connected to the adapter, through which a spacer element, a superstructure, and/or prosthesis may be attached/fastened to the adapter.
  • a seat 16 is located above the threaded female part 15, or closer to the second end of the adapter than said threaded female part.
  • the seat 16 corresponds to an abutment of a spacer element, a superstructure, and/or a prosthesis, such that a fitting between the adapter and said spacer element, superstructure, and/or prosthesis may be obtained.
  • Figs. 2a and 2b illustrates end views of two embodiments of the adapter of said second end.
  • the seat 16 may be a circular seat, according to Fig. 2a, or a main circular seat with indentions 21, according to Fig. 2b.
  • These indentions 21 may have a radius smaller than the radius of the circular seat 16.
  • the number of indentions may vary.
  • the number of indentions may be 1, 2, 3, 4 or 5, or even more than 5, as long as the purpose of the indentions fulfil the object of hindering a dental structure and/or a spacer element from rotating.
  • a dental structure such as a prosthesis or superstructure
  • a circular seat may provide a satisfying seat, since the dental structure itself will hinder rotation. This is due to the fact that the dental structure is attached at more than one point, thus locking the dental structure.
  • the seat 16 may have other suitable forms, allowing for the hindering of rotation of a spacer element, a superstructure, and/or a prostheses.
  • Such other suitable forms may be a square shape, a rectangular shape, a triangular shape, other polygonal shapes, or a star shape.
  • the shape of the seat 16 may be tailored to fit the different spacer elements, superstructures, and/or prostheses available on the market. Thus, it will be possible to obtain a platform switch from the conical implant platform to any suitable platform asked for.
  • the seat is provided on the spacer element, superstructure, and/or prosthesis, whereby an abutment corresponding to such seat is located on the adapter.
  • the threaded female part 15 and the tool grip portion 14 may be provided, within the boundaries of the abutment, or next to said abutment, such that the abutment may be fastened to the implant and a spacer element, a superstructure, and/or a prosthesis in turn may be fastened to the adapter.
  • the side or sides of the seat, and thereby also on the corresponding abutment, may be slightly angled. This arrangement permits a tight attachment between the adapter and the spacer element, superstructure, and/or prosthesis.
  • the frictional forces between the two congruent, smooth- finished circumferential surfaces can be adjusted, on the one hand as a function of the tightening force or choice of material and, on the other hand, as a function of the angle of convergence of the surfaces.
  • the adapter may for example be made of titanium, but other materials with a sufficient degree of biocompatibility and strength to be able to serve permanently as a bone anchor for prosthetic structures in the form of spacer elements, superstructure, crowns, bridges and other prostheses. These can be made of ceramics, metal, or tissue-compatible plastic, or combinations thereof. Also, different combinations of material can be used for different indications. For example, when, for reasons of space, the adapter has to be given an extremely small volume, it can have a core of especially strong alloys and a coating of pure titanium and/or hydroxyapatite in order thereby to increase the strength of the adapter.
  • the main body 11 has a conical shape corresponding to a conical inner shape of a dental implant, such as Conical Seal DesignTM.
  • a dental implant such as Conical Seal DesignTM.
  • This arrangement permits a tight attachment between the main body 11 of the adapter and the dental implant.
  • the frictional forces between the two congruent, smooth-finished circumferential surfaces can be adjusted, on the one hand as a function of the tightening force or choice of material and, on the other hand, as a function of the angle of convergence of the surfaces. If this angle is sufficiently small, the two components can be tightened so hard that it is practically impossible to distinguish them.
  • the second end of the main body 11 preferably ends at the same plane and/or level as the dental implant, whereby the connection recess 13 of the adapter will be located at a fixture level, i.e.
  • connection recess 13 there is no need for elevation of the connection recess 13 above the dental implant, which will be the case when using spacer elements. This may be accomplished since the grip portion 14 is located within the connection recess 13, whereby there is no need for a separate grip portion protruding from the second end.
  • the main body 11 fills the connection recess of the implant with a conical connection recess, such that the main body 11 has substantially the same volume as the recess of the implant, except for the connection recess 13 and the grip portion 14.
  • a dental implant may be adapted instead of replaced by the aid of an adapter according to the present invention, when a new dental implant would better suit the dental situation of the patient, which may be the case if the patient is in need of some kind of reconstruction of the dental structure, such as for example in case of loosing yet another tooth.
