Definitions

  • Intraosseous dental implants have the property of the osseointegration, where an element foreign to the bone tissue is inserted and integrated therein, without rejection.
  • a dental implant consists of a surgical technique where the surgeon performs the bone preparation through an opening (hole) with dimensions smaller than the implant, and then performs the said initial stabilization, when the implant is placed by through the application of torque in order to penetrate the threads of the implant into the bone tissue.
  • the quality of initial stabilization is a result of factors such as the shape and dimensions of the opening made in the bone preparation, implant geometry, applied torque values, among others.
  • Torque control applied by the surgeon plays a key role in the quality of the initial stabilization of the implant.
  • the initial stabilization of the implant is determinant in the process of osseointegration.
  • the surgeon uses a said placement wrench that has the ability to temporally attach to the Implant so that the surgeon can manually transmit, with the aid of a torque wrench, the torque required for the implant.
  • the surgeon will cease the application of torque and uncouple the implant placement wrench by simply the surgeon pull the placement wrench in the direction of the longitudinal axis of the placement wrench.
  • the coupling between the placement wrench and the implant is usually made by means of geometrical arrangements between the placement wrench and the implant coupling means.
  • implant manufacturers and placement wrenches use coupling systems comprising 6 to 8-sided geometries, i.e., hexagonal and octagonal cross-sectional geometry, respectively.
  • U.S. Patent US6626911B1 issued to Engman et a/., discloses geometries for engagement between the placement wrench and the implant coupling member, wherein said geometries include non- planar surfaces of variable radius of curvature, in order to increase the resistance to plastic deformation of the implant.
  • a dental implant (10) constructed in accordance with the constructive principles of the present invention has an imaginary central longitudinal axis (e), means for bone interpenetration (11), prosthetic interface (12), coupling region (13), wherein the coupling region (13) has a geometric configuration of the double heptagonal type.
  • Figure 1 Shows a placement wrench having engaging means constructed in accordance with the scope of the present invention
  • Figure 2 Shows a placement wrench coupled to an implant both constructed according to the scope of the present invention
  • Figure 3 Shows a detail of the engagement between the placement wrench and the implant shown in figure 2.
  • Still further objective of the present invention is a torque transmission method comprising the use of implants and placement wrenches comprising the constructive details and features of the present invention.
  • a dental implant (10) constructed in accordance with the constructive principles of the present invention resists the stresses resulting from torques transmitted by means of a placement wrench (20) which are significantly higher than torques typically employed by surgeons without plastic deformations.
  • a dental implant (10) constructed in accordance with the constructive principles of the present invention has a coupling region consisting exclusively of planar surfaces.
  • a dental implant (10) and a placement wrench (20) were constructed in surgical titanium by machining, in accordance with the constructive principles and feature of the present invention, as shown in Figures 1 to 3, and further detailed follow.
  • the dental implant (10) having an imaginary central longitudinal axis, means for bone interpenetration, prosthetic interface, a coupling region, a coupling region having a geometric configuration of the double heptagonal type.
  • the prosthetic interface being of the external type and having hexagonal geometry, the means for bone interpenetration being threaded threads.
  • the cross section characterized by having 14 vertices, and 28 flat edges.
  • the flat edges forming an approximate angle of 25 0 between each other.
  • the cross section also has interconnecting segments. In such a way that the flat edges either are interconnected by the vertices or are interconnected by the interconnecting segments, interleaved.
  • a placement wrench (20), shown in Figure 1 had a coupling region called a double heptagonal, being a volume having a "straight prism" geometry, i.e., having a cross-sectional area constant geometry, and longitudinal planes parallel to the longitudinal axis.
  • Figure 2 by means of a cut-off in the coupling region, describes how the coupling region has been accommodated in the respective coupling region.
  • a dental implant placement system made in accordance with the principles of the present invention comprises the use of a placement wrench (20) and a dental implant (10), wherein the placement wrench (20) comprises 14 vertices in its coupling region and the dental implant (10), 14 vertices in its coupling region, to transmit the torques required for the dental implant placement.
