Definitions

  • the present invention relates to a dental implant made of plastic, ceramic or titanium with an implant body having a main and a micro-thread and a bulbous outer geometry.
  • Dental implants are usually made of titanium. Increased environmental pollution by metals, electrosmog, toxins and a steadily growing number of different substance classes cause in the human and animal body more and more sensitizations, allergies and intolerances. Titanium ions alone, which can be detected after a titanium implantation in the regional lymph nodes, can be an increasingly serious medical problem. Therefore, there is a need for alternative implants.
  • the object of the invention is therefore to make available an improved dental implant.
  • the object of the present invention is achieved by a dental implant with an implant body, which produces an abdominal pressure distribution on the surrounding bone through its outer geometry.
  • a dental implant which comprises an implant body with a main thread, wherein the implant body has a bulbous outer geometry.
  • the main thread deepens towards the tip of the implant body.
  • the tip of the implant body is the opposite end of the abutment.
  • the implant body further has a micro-thread cut into the main thread.
  • the micro-thread extends from about the middle of the implant body to the base of the implant body.
  • the base of the implant body is the end facing the abutment.
  • the micro-thread compresses from about the middle of the implant body towards the base of the implant body.
  • the implant further comprises an abutment, wherein the implant body and the abutment comprise a material independently selected from the group comprising a non-metallic material, ceramic, preferably zirconia, and titanium.
  • the non-metallic material is selected from the group comprising plastic, preferably PEEK (polyether ketone) and blends with PEEK or PAEK (polyaryletherketone) and blends with PAEK.
  • plastic preferably PEEK (polyether ketone) and blends with PEEK or PAEK (polyaryletherketone) and blends with PAEK.
  • the implant body comprises a non-metallic material, ceramic or titanium
  • the abutment comprises a non-metallic material, ceramic or titanium
  • the implant body comprises plastic, preferably PEEK or PAEK, and the abutment comprises a non-metallic material, plastic, preferably PEEK or PAEK, ceramic, preferably zirconium dioxide, or titanium.
  • the implant body comprises ceramic, preferably zirconia, and the abutment comprises a non-metallic material, plastic, preferably PEEK or PAEK, ceramic, preferably zirconia, or titanium.
  • the implant body comprises titanium
  • the abutment comprises a non-metallic material, plastic, preferably PEEK or PAEK, ceramic, preferably zirconium dioxide, or titanium.
  • the abutment comprises a conical section with square and conical tip.
  • An abutment with a tapered portion with square and conical tip may also be used in combination with implants other than those described herein.
  • Figure 1 shows an implant body (1) with a tip (2) and base (3) and a main thread (4), which recesses towards the tip, and the position of the micro-thread (5) in the main thread from the center of the implant is cut.
  • Figure 2 shows an angled abutment (6) with four-edged pilot (7).
  • Figure 3 shows a straight abutment (6) with four-edged pilot (7).
  • the dental implant according to the invention is in two parts and comprises an implant body and an abutment as well as an implant / abutment connection.
  • the surface of the dental implant is hydrophilic. It is blasted, etched and / or plasma treated.
  • the implant shaft is polished about 0.7 mm wide.
  • the implant body and / or the abutment non-metallic materials such as plastic, such as PEEK (polyether ketone) or PAEK (polyaryletherketone), and ceramics, such as zirconia, provided. Titanium or titanium compounds are also considered.
  • the construction, eg shape, dimensions, etc., of the implant body and abutment is such that these two parts fit together and form a two-part dental implant, regardless of which material these two Parts are made. That is, the material of the implant body and that of the abutment can each be freely selected, and the implant body and abutment need not necessarily be made of the same material. In this case, for example, the combination of ceramic plastic or plastic plastic is possible.
  • a main thread is cut from a parallel-walled cylinder, which recesses to the tip, resulting in a conical implant core.
  • an additional thread i. a compacting micro-thread, cut to the implant base, i. towards the abutment, extends.
  • the combination of the main thread and the micro-thread results in a "bulbous" outer geometry of the implant body, ie the circumference of the implant body is greater in a central region than the circumference of the region above (towards the tip) the part of the implant body which faces away from the abutment and is first introduced into the jawbone, while the term “base” refers to that part of the implant body which faces away from the abutment.
  • Main and micro threads are partially broken.
  • the contact pressure of the implant in the jawbone is highest in the middle area.
  • the contact pressure is reduced by the micro-thread, in the lower area is given a pressure reduction by the conical implant body.
  • the middle in the area of cancellous bone there is therefore the highest contact pressure with the strongest primary stability after implantation and in the upper area a trauma prophylaxis of the corticalis.
  • a maximum cutting performance of the implant body is achieved in the lower area.
  • the described construction of the dental implant is particularly advantageous when using plastic or ceramic. However, it can also be applied to titanium implants. Due to the construction-related reduction of the insertion torque, titanium abrasion in the hard bone is reduced. In this way, a dental implant is provided by the construction according to the invention which addresses the problem of titanium deposits in the body. Side, for example by the use of plastic ("metal-free implant”), or at least mitigates.
  • the angled titanium implant has a slight scalloping.
  • an oval, sharpenable abutment is provided for bending.
  • connection of iniplantate body and abutment consists of a conical connection, which has a rotation lock in the area of the tip.
  • the anti-rotation device is configured as a square in an abutment made of plastic or ceramic, i. square with rounded edges. This embodiment at the tip of the abutment facilitates the insertion of the abutment into the implant (function as "pilot").
  • ⁇ br /> ⁇ br /> In a titanium abutment, the anti-rotation device is configured as a square with a screw connection through the central screw an octagon, allowing eight different positions of the abutment.
  • a plastic or ceramic abutment is glued, a titanium abutment is screwed into the implant body.
  • the bonding of the plastic or ceramic implant distributes the contact pressure, so that the implant does not burst even with a conical abutment connection. Furthermore, the load is axial and there is no direct wedge effect. After osseointegration, the bone counter pressure and the slight residual elasticity of the bone act as a fracture prophylaxis.
