Definitions

  • the present invention relates to an implant in which the vertical groove is formed in the side groove and the lower thread to improve the structure in order to reduce the excessive stress generated in the implant implanted in the alveolar bone.
  • an implant means a replacement that is originally restored when human tissue is lost, but dental implants refer to implanting artificial teeth.
  • the roots made of titanium (titanium), etc. which are not rejected by the human body, are planted in the alveolar bone where the teeth fall out, and the artificial teeth are fixed to restore the function of the teeth.
  • the surrounding teeth and bones are damaged over time, but the implants do not damage the surrounding dental tissues, and they have the advantage that they can be used semi-permanently because they have the same function or shape as natural teeth and do not cause tooth decay.
  • the fixture of such a dental implant (Fixture) is passed through the tight bones of high bone density and penetrated into the spongy bone of low bone density.
  • the fixture of the dental implant embedded in the alveolar bone does not have a physiological movement to relieve the stress applied to the self by being directly adhered to the bone tissue, so that a large stress is generated in the surrounding bone by mastication pressure (vertical pressure).
  • Each of the fixing screws includes a threaded portion and a washer portion at the outer end of the threaded portion, and has a sufficient width to engage an adjacent outer bone surface when the threaded portion is mounted to the bone to laterally support the threaded portion.
  • the threads have threads of various sizes, and the washer portion is intended to penetrate the gum tissue so that the washer portion can engage the adjacent outer bone surface upon which the thread portion is mounted within the bone.
  • Each fixation screw is provided with a lateral bore at the outer end of the fixation screw to receive sutures or the like through the fixation screw to prevent the fixation screw from falling into the oral cavity. Orthodontic appliance fixing and fixing method are described,
  • a first implant 24 and a first peak 25 in a dental implant fixture that is inserted into an alveolar bone of a human body while rotating about a central axis to form an artificial tooth.
  • the first screw thread 23 disposed alternately in the direction of the central axis is formed with the body portion 20 formed on the outer circumferential surface, and integrally with the body portion 20 at the lower side of the body portion 20 and the diameter toward the lower side. It is narrowed and the second screw thread 31 is alternately arranged in the direction of the center axis of the second bone and the second peak is made of a tapered portion 30 formed on the outer peripheral surface,
  • the dental implant fixture is characterized in that the distance has a ratio of 0.17 ⁇ 0.21: 1,
  • a dental implant having a fixture embedded in an alveolar bone, wherein the fixture has a cross section continuous over the entire circumference substantially along the rim at an upper end thereof. It is formed in a closed loop (CLOSED LOOP) shape, the dental implant is characterized in that it has an outer inclined contact coupling portion that the outer diameter of the outer wall is increased from the top to a predetermined distance downward,
  • Publication No. 20-0392306 discloses a dental implant fixture comprising a trunk portion having a predetermined length and extending to a threaded inner circumferential surface, wherein a plurality of three-dimensional pores are formed on the outer circumferential surface of the trunk portion. It can be seen that the fixture fixture for which the three-dimensional pores are formed is disclosed.
  • the present invention increases the contact area with the bone in the upper 1/5 ⁇ 1/3 (dense bone contact area) of the fixture to solve the above problems, disperses the stress concentrated on the surface bone around the fixture, mastication pressure Side grooves with improved structure to form grooves on the side edges that can effectively resist (vertical pressure) and vertical incision grooves for implanting the removed bone fragments into the side grooves when the fixture is placed on the lower thread line. It is a technical solution of the present invention to provide the formed implant.
  • the present invention has increased the overall contact area between the implant and the alveolar bone, the position of the side groove is located in the dense bone, which is advantageous for the dispersion of stress concentrated on the surface bone around the fixture, and the bone contact surface by the edge of the groove formed in the direction of the central axis By giving this cut form delays the continuous bone absorption, and has the advantage of effectively resisting mastication (vertical pressure).
  • the present invention is the head portion 1, the upper groove (2) provided with a groove in the upper center of the head portion 1, and a screw thread on the lower surface of the head portion (1)
  • the vertical groove is formed in the side groove and the lower screw thread consisting of a lower portion (3) provided, a plurality of vertical incision groove 11 cut perpendicularly to the screw line, and a side groove (10) formed over the entire upper edge of one side It relates to an implant formed.
  • the present invention relates to an implant having a plurality of vertical incision grooves in the lower thread and grooves to prevent the increase of contact area or stress distribution and bone fracture in the cortical bone after implantation in the alveolar bone.
  • Lateral grooves increase the overall contact area between the implant and the alveolar bone, and the position of the side grooves is located in the dense bone, which is advantageous for stress distribution, and the bone contact surface is cut off by the lower edge of the groove to delay continuous bone absorption.
  • resists mastication vertical pressure
  • the groove is inclined upward 20 ⁇ 60 ⁇ .
  • the width is 1 ⁇ 2mm and the depth is 0.5 ⁇ 1.5mm.
  • a shape inclined upward by 45 ° toward the central axis direction is preferable, and the width and length are preferably 1 mm.
  • the vertical incision groove serves to implant bone tissue into the lateral groove by deleting the alveolar bone when the fixture is placed.
  • the procedure is the same as a conventional implant procedure, but due to the difference in structure, the side groove edge of the present invention enables effective resistance to mastication (vertical pressure) and increases the contact area with the bone.
  • the implant was implanted into the alveolar bone, to facilitate dissipation of stress concentrated on the surface bone around the fixture.
  • FIG. 1 is a view showing the entire implant of the present invention
  • Figure 2 is a detailed view of the implant of the present invention, head (1), upper groove (2), lower (3), side groove (10) and vertical incision groove (11) It can be seen that.
  • the implant of the present invention includes a head 1, an upper groove 2 provided with a groove in the upper center of the head 1, and the head ( 1) a lower portion (3) provided with a screw thread on the lower surface, a plurality of vertical incision grooves 11 cut perpendicularly to the screw thread,
  • the structure is formed over the entire side rim of the upper side and has a side groove 10 having a width of 1 to 2 mm and a depth of 0.5 to 1.5 mm in a shape inclined upward 20 to 60 degrees toward the center axis direction.
  • the present invention relates to a dental implant having a plurality of vertical incision grooves in the groove and the lower thread to prevent the increase of contact area or stress distribution and bone fracture in the cortical bone after implantation.
