Definitions

  • the invention is in the field of medical technology and relates to a dental implant system.
  • the dental implant system has an implant and a secondary part (also called 'abutment'), it being possible to build on the secondary part a structural element ("superstructure " ) which, for example, can form an artificial crown.
  • the implant system may also include any system-specific tools for creating a model for the dental technician.
  • the invention also relates to an implant, a secondary part, a laboratory analog of an implant and a positioning tool.
  • Implant systems are available on the dental market. They are based on a screw body on which an artificial crown or another
  • Supra structure is constructed via a secondary part. This procedure makes it possible to compensate for possible misalignments and axial divergences of adjacent implants. In addition, the relocation of the abutment selection makes one
  • an inner polygon for example a hexagon or an octagon
  • the secondary part having a corresponding outer polygon engaging in the inner polygon as a guide surface, as a result of which Angular position (ie the position in the azimuthal direction) of the secondary part is determined.
  • First problems show up when transferring the oral situation to a master model for the dental technician.
  • a so-called impression tray with impression material is used, which is guided into the patient's mouth.
  • a positioning tool for example a positioning cylinder
  • the removal of the impression depending on the (oblique) position of the implant may be difficult, and the full recovery of the impression material is not always guaranteed because of the large delay.
  • Retentive sites on adjacent divergent implants can become almost insurmountable with rigid interlocking.
  • the provision of the impression material should be less complete because of the greater delay.
  • the abutments ultimately vary in their vertical orientation and angular position, ie they come to lie in different positions in the laboratory analog and in the implant. Divergences in the angular position have a particularly disadvantageous effect in this context, in particular when non-rotationally symmetrical secondary parts are used. Crown bridge assemblies on angled abutments will achieve optimum fit (passive fit with good edge closure) only for a defined position of the abutments. If these abutments are transferred from the model to the mouth, they may come to rest in a slightly different position (depending on the tightening torque), resulting in poor fit.
  • the dental implant system has an implant and a secondary part, which can be attached to the implant in a rotationally fixed manner, and on which a superstructure can be built.
  • a positioning tool is available to change the position of the
  • the implant has a recess projecting inwards from a coronal end face into which an apical end of the positioning tool can be inserted. It is characterized in that grooves or cams are formed in the recess, which together with corresponding cams or grooves of the introduced into the recess apical
  • the implant has grooves in the recess (ie, the inner funnel) (they may be formed as arbitrarily shaped guide grooves be) or cams, which cooperate with corresponding cams or grooves of the secondary part and form a positioning aid and protection against rotation.
  • these grooves or cams are just after the coronal end face of the implant, ie they are located in the region of the transition between an optionally existing implant shoulder and the inner funnel.
  • “In the area of the transition” means for grooves, that they connect directly to the transition to the implant shoulder, in the case of cams not more than 2 mm, preferably at most 1 mm away from the transition.
  • the "cams” may be of any shape as long as they are insertable into the grooves and have widths to tolerances, preferably an oblong-rectangular shape, so that the groove-cam connection is more or less a tongue-and-groove connection.
  • the number of grooves in the implant or in the secondary part corresponds to the number of surfaces of the polygon (for example 8 for an octagon) or is an integer multiple or a fraction of the number of surfaces.
  • the number of cams is that of the grooves or is a fraction of that number (eg, 2 or 4 at 8 grooves).
  • a positioning tool for the transfer to the model - this tool has of course as the secondary part cams or grooves - made of metal, whereby the precision is increased.
  • FIGS. 1a and 1b each show an implant or the laboratory analog to the implant according to the prior art together with an associated positioning tool and a copying impression cap.
  • FIGS. 2a and 2b illustrate the problem of poorly defined angular position, as it results between implant or laboratory analog and secondary part or positioning tool.
  • 3a and 3b each an implant or a laboratory analog to the implant according to the invention together with an associated positioning tool and a Abformkappe with snap mechanism
  • FIGS. 4a to 4c each show an implant laboratory analog according to the invention together with the three versions of a secondary part according to the invention.
  • the implant 1 according to FIG. 1 corresponds to a product available on the market. It has a trained as a screw apical area 1.1 and a coronal area 1.2 and is formed on its outer surface osseointegrative. At its coronal end, the implant has a shoulder surface 1.3. From the coronal end face inwards, an inner funnel is formed, which subsequently forms an inner polygon 1.5, namely an inner octagon, on a cylindrical or conical section 1.4. Apical from the inner polygon 1.5, the implant still has a not visible in the drawing internal thread into which an occlusal screw for attaching a secondary part can be introduced.
  • the implant is made, for example, of titanium or of a titanium alloy.
  • a positioning tool 3 is made of plastic and has a cylindrical shape. It has an apical outer polygon 3.1 which fits into the inner polygon 1.5 of the implant and a further outer polygon 3.2 for the rotationally fixed anchoring of the positioning tool in the impression during the transfer of the implant angular position to a model.
  • a dental technician together with the dentist, if necessary, can select the appropriate abutment from a selection of secondary parts and make a superstructure.
  • the positioning tool 3 is inserted into the implant inner funnel until the apical outer polygon engages in the inner polygon of the implant.
  • the impression cap and the positioning tool are positioning tools.
  • the positioning angle 3 defines the rotational angle position of the implant laboratory analog 5, which has an inner funnel with an inner polygon 5.5 corresponding to the structure of the implant.
  • the impression cap is used to define the vertical position during the impression process and is required for the correct transfer of the same from the oral situation to the model and for the reproduction of the implant shoulder position.
  • Figs. 2a and 2b The above-mentioned problem of insufficient definition of angular position and tilting is illustrated in Figs. 2a and 2b.
  • the rotational position of the positioning tool 3 relative to the implant 1 and the laboratory analogue 5 (in the illustration in the figure, the element 1, 5 designate both the implant and the laboratory analog) may vary by a considerable amount, as the difference between the nominal position of FIG 2a and the tilted position of Fig. 2b.
  • the same inaccuracy also arises between Laboranalog 5 / Implant 1 and Secondary Part 2 when working in the laboratory or in the clinic when attaching the abutment to the implant of the patient (ie in the figure, the element 3, 2 together with the positioning tool and the secondary part in Section).
  • the drawn inaccuracy can thus quadruple; this is the more so as a deviation from the target position generally in the screw rotation direction 6 will be observed.
  • FIG. 3a shows an implant 11 according to the invention, wherein the reference numerals 11.1, 11.2, 11.3, and 11.5 show the apical region, the coronal region, the shoulder surface and an inner polygon analogously to the implant according to FIG.
  • the material of the implant as well as the osseointegrative surface can be chosen the same as in the known implant.
  • the Implant at the coronal end of the inner funnel, so in the region of the transition between the shoulder surface 11.3 and the inner funnel and then to the shoulder surface 11.3 a plurality of axially extending grooves 11.6 or grooves.
  • the inner funnel limiting surface in the region of the grooves 11.6 is slightly conical, but they could just as well be cylindrical or cylindrical and conical.
  • the positioning tool 13 does not have a part to be inserted into the interior of the inner funnel, but rather cams 13.6 arranged on its lateral surface at the apical end, which are insertable into the grooves of the implant.
  • cams 13.6 arranged on its lateral surface at the apical end, which are insertable into the grooves of the implant.
  • not every groove must correspond to a cam of the positioning tool;
  • the tool has only four cams whereas eight grooves are present in the implant.

Abstract

L'invention concerne un système d'implant dentaire présentant un implant (11) et une partie secondaire, pouvant être fixée sur l'implant de manière bloquée en rotation et sur laquelle une superstructure peut être montée. De plus, un outil de positionnement (13) est prévu pour transmettre à un modèle la position de l'implant dans la bouche d'un patient. Cet implant présente un évidement qui s'étend vers l'intérieur depuis une face coronaire et dans lequel une extrémité apicale de l'outil de positionnement peut être introduite. Ce système se caractérise en ce que des rainures (11.6) ou des bossages sont formés dans l'évidement et forment, conjointement avec des bossages (13.6) ou rainures correspondants de l'extrémité apicale de l'outil de positionnement, introduite dans l'évidement, un verrouillage stable par rapport à des rotations de l'outil de positionnement (13) autour d'un axe d'implant (11.7).
