Definitions

  • the invention relates to a dental implant set according to the preamble of claim 1.
  • Implants, bone substitute materials, membranes and surgical instruments, especially implant drills, are used as essential components and instruments in the context of implant treatment in suboptimal bone conditions.
  • the bone is initially prepared for the planned position and implant size by means of a cut or a punch with implant drills after opening the gum at the selected implant site.
  • implant drills From the prior art, a variety of implant drills is known.
  • membranes By using additional membranes, a shield against the invasion of connective tissue is achieved, which would prevent the bony regeneration of the defect.
  • synthetic polymers such as polylactides or polyglycolides and their chemical modification are preferably used in the prior art.
  • the membranes are very thin elastic films. A distinction is made between resorbable membranes which are broken down by the body and do not need to be removed, as well as nonabsorbable membranes.
  • the remaining bone defect is filled up with synthetic bone substitute material and, in turn, provided with a membrane.
  • the bone substitute materials known from the prior art have a granular structure and, depending on the particle size, after introduction have the property of being compressible under external pressure, which leads to an undesired irregularity in the final bone structure.
  • Such changes in the augmentation structure i. E.
  • the increase in bone mass can already be induced intraoperatively by the process of suture closure of the implantation wound.
  • the elasticity and plasticity of the currently used membrane in the augmentation does not provide sufficient protection against external compression.
  • the conventionally used membranes do not currently provide optimal shielding from invasive connective tissue cells.
  • bone strength around the implant of 1.5 to 2 mm located beneath the bone membrane is often undershot as a result of the use of the conventional bone substitute materials in conjunction with the membrane, which considerably impairs the prognosis of the durability of the implant.
  • the object is achieved in that the bone substitute material and the membrane of hard and firm nature.
  • the core idea of the invention is to avoid elastic deformation with a concomitant change in volume and increase in density of the bone substitute material and the membrane due to incompressible formation of the bone substitute material and of the membrane.
  • a solid and hard state of the granular bone substitute material as well as the membrane, for example of polylactide, is almost incompressible.
  • the transfer of a granular material for the bone substitute material to a solid and hard state can be accomplished by conventional methods such as sintering or gluing with fibrin glue.
  • the transfer of the membrane into a hard and solid state can also be realized by conventional methods.
  • the set has a face milling cutter as a surgical instrument. Face milling cutters have already found use in the context of medical treatments, as shown in DE 20 2007 003 035 U 1 for knee endoprosthesis care.
  • an end-face milling cutter is expediently suitable, which has a lower-side cutting surface, whereby a cavity above the cavity created for the implant can be produced, which has a larger diameter than the cavity.
  • the inserted and screwed into the cavity implant protrudes into the cavity, so that the bone substitute material according to the invention can be arranged around the upper region of the implant.
  • the bone replacement material which is preferably arranged in a ring around the implant, thus forms a non-positive and positive connection with the implant, as well as after incorporation with the surrounding bone.
  • Claim 6 therefore provides that the bone substitute material is annular.
  • a practicable variant of the invention provides that the set has a drill bit as a surgical instrument.
  • the use of drill bits in dentistry is known.
  • DE 35 43 737 AI discloses a drill bit for root canal treatment.
  • the use of a drill has the advantage that the generation of the cavity for the implant and the generation of the cavity for the bone substitute material can be completed in one operation.
  • the invention provides a dental implant provided with a bone substitute material of granules, the bone substitute material being of firm and hard nature. So provided is a one-piece structure, which is composed of the implant and the bone substitute material.
  • the implant may preferably be provided with a solid and hard membrane. All components, ie. Implant, bone substitute material and membrane, while expediently be releasably connected together.
  • the invention also provides for the use of the bone substitute material according to the invention, the membrane according to the invention and the use of the face milling cutter for dental implantology.
  • Fig. 1 shows in a sectional view the dental implant set according to the invention, wherein the components of the set are shown after the implantation,
  • Fig. 2 shows in a sectional view a cavity produced for the implant and a cavity for the bone substitute material in a jawbone
  • Fig. 3 is a sectional view of a face milling cutter as a further component of the dental implantation set according to the invention, the face milling cutter being shown during use in a dental implantology
  • Fig. 4 shows the steps of a dental implantology in a sectional view, in which components of the dental implant sets according to the invention are used.
  • Fig. 1 shows the dental implant set according to the invention, which is provided with the reference numeral 1 and whose components are shown in the state of the implant 2 inserted in the toothless region of the jaw bone 5 and of the gum 6 sewn over the implant region.
  • the components of the implant set 1 include the bone substitute material 3 and the membrane 4.
  • the implant 2 around the bone replacement material 3 is arranged annularly.
  • the granular bone substitute material 3 is not in a loose granular but in a solid and hard state, so that the bone substitute material 3 as a ring-shaped hard block one previously generated for bone augmentation and in FIG. 2 cavity 15 fills accurately.
  • the cavity 15 is bounded with pierced and opened gums 6 from a longitudinal side 16 and a shorter side 8, which is formed at the upper end of the cavity 9, so that the cavity 9 in contrast to the conventional practice In a sense, by the one larger diameter than the cavity 9 having cavity 15 undergoes a spatial expansion.
  • the dental implant set 1 also has, as FIG. 1 further shows, a membrane 4 which, like the bone substitute material 3, is of solid and hard nature.
  • the integrally formed membrane 4 surrounds both the upper The end face of the implant 2 and the bone substitute material 3 as well as a part of the wall of the bone replacement material 3 designed as a hard annular block and thus adapts to the upper and lateral outer contour of the bone substitute material 3 and the implant 2, respectively.
  • the membrane At the lower end of the part of the membrane 4, which faces the lateral outer contour of the bone substitute material 3, the membrane has a plastically deformable end piece 18 in order to achieve optimum adaptation in the transition of the membrane 4 to the bone 5.
  • the implant 2 is detachably connected to the membrane 4.
  • the membrane 4 has a hole 7a and the implant 2 via a corresponding to the hole 7a push button 7, so that the membrane 4 can be placed or plugged onto the implant 2.
  • the push button 7 is part of a locking screw, which is an integral part of the implant 2 and with which the upper end of the implant 2 is closed.
  • FIG. 3 shows, as a further component of the dental implantation set 1 according to the invention shown in FIG. 1, specifically during a dental implantation step, a face milling cutter 17 in the form of a face milling cutter.
  • the face milling cutter 17 has an end mill element 10 which has a cutting edge 12 on the underside.
  • a centering pin 13 is arranged whose length and depth corresponds to the length and depth of the cavity 9 shown in FIG.
  • a fastening element 14 which connects to a coupling element shown in FIG. 3 produces drive not shown.
  • a drill bit may also be provided which has a drilling portion instead of the centering pin 13, so that the function of a countersink bit and a face milling cutter is combined in one tool.
  • the diameter of the centering pin 13 of the face milling cutter 17 corresponds to the diameter of the cavity 9.
  • the present in the form of a face milling cutter face milling 17 mills by means of the cutting edge 12 in FIG. 2 showed standardized cavity 15.
