Definitions

  • All parts of the implant of the utility model are made of metal and / or ceramic, and the cross section of the thread is rectangular.
  • the thread design can effectively improve the contact rate of the implant-bone interface, and the bioactive porous ceramic coating can be selected in the middle and lower sections. Layer or titanium coating or acid etching layer to shorten the time of osseointegration.
  • the implant of the present utility model has a single or multiple retention grooves in the lower and middle surface of the implant, which increases the anti-torsion capability of the implant.
  • the implant of the utility model has a smooth or finely threaded surface with an upper part of the implant of more than 2mra, and a wide neck diameter is conducive to improving biomechanical compatibility, and it is also conducive to the restoration of implant dentures.
  • Figure 1 is a schematic diagram of the overall structure of the utility model
  • Figure 2 is a schematic structural diagram of the utility model (stepped spiral type)
  • the implant of the present invention includes: an implant 1, a gingival ring 2, a gingival ring screw 3, an abutment 4, and an abutment screw 5, which are characterized in that the implant 1 is a spiral type,
  • the thread cross section is rectangular.
  • the implant 1 has a stepped spiral type, and the steps are divided into 3 to 6 sections.
  • the implant 1 has a conical spiral type, and the taper of the conical spiral type is 0 to 30 degrees.
  • the upper section of implant 1 has a smooth surface or fine thread design of more than 2rara, and the neck diameter is wide.
  • the implant 1 is made of pure titanium or titanium alloy, and the remaining parts are made of titanium alloy or ceramic.
  • the surface of the middle and lower sections is provided with a single or multiple anti-torsion retention grooves.
  • the implant 1 is made of pure titanium or titanium alloy, and the surface of the middle and lower sections can be optionally coated.
  • Gingival ring screws 3 are ordinary spiral or tapered spiral or closed spiral.
  • the diameter of the lower cross section of the implant system can be 4 mm, which is far less than the requirement of not less than 6 mm for columnar implants.
  • the elastic modulus of cortical bone can range from 10,000 to
  • 13400Mpa but not more than 13400Mpa which is strictly required by traditional implants.
  • For bite force under the same conditions, it can be improved by at least 20%.
  • the implant is implanted with a special set of drill bits and prepared on the bone. Six months later, the two-stage operation completes the gingival ring, the abutment fixation, and the restoration of the implant denture.
