Abstract

DC60 (07/05/40) This invention relates to a large helix or coarseness arranged for bone implants, specifically dental implants that are helixated. A portion of such helix or coarseness (e.g., framework) consists of two wings. The upper wing, radius R, whose apex is formed by the intersection of the two wings, has a lower radius r formed at the bottom of the groove between two adjacent helixes or coarsenesses. Such wings form an angle V with a plane perpendicular to the cross-section of the helix or coarseness and Perpendicular to the surface of the bone implant, the aforementioned framework has a height D corresponding to the invention. The size of the thread or roughness shall be subject to the following specifications: for 10 degrees less than or equal to V less than or equal to 35 degrees, R greater than 0.4 x D, and for 35 degrees less than or equal to V less than or equal to 55 degrees, R greater than 0.2 x D. In popular shapes, the specifications are: for 0.05 mm less than or equal to D less than or equal to 0.5 mm and 25 degrees less than or equal to V less than or equal to 55 degrees, the radius on R shall be greater than 0.2 x D but less than D, and for 0.25 mm less than or equal to D less than or equal to 0.5 mm and 10 degrees less than or equal to V less than or equal to 35 degrees, R greater than 0.4 x D but less than D. Figure 1. This invention relates to large threads or roughnesses provided for bone implants, specifically dental implants made in threaded form. Or such roughness (e.g., outline) consisting of two wings, the upper radius R at the apex is created by the intersection of these two wings, the lower radius r is created at the bottom of the groove between two adjacent threads or roughness. Such wings, which form an angle V with the axis, are perpendicular to the cross-section of the thread or roughness and perpendicular to the surface of the body of the embedded object. Such outline also has a height D corresponding to the fabrication of the dimensions of the thread or roughness, which will be subject to the following designations: for 10 degrees less than V less than 35 degrees R greater than 0.4 x D, and for 35 degrees less than V less than 55 degrees R greater than 0.2 x D in popular shapes. The requirements are for 0.05 mm, less than D, less than 0.5 mm, and 25 degrees, less than V, less than 55 degrees, the radius on R is greater than 0.2 x D but less than D, and for 0.25 mm, less than D, less than 0.5 mm, and 10 degrees, less than V, less than 35 degrees, R is greater than 0.4 x D but less than D.

Claims (1)

1. A large helix or coarseness arranged for bone implants, particularly dental implants that are helix-shaped. A portion of such helix or coarseness (e.g., framework) consisting of two straight wings and a curved apex with an imaginary radius R at the apex is created by the intersection of the two wings, defining the transition point P1 between the straight wings and the curved apex. The first tangent passes through P1, which is dictated along the wings, as well as the apex P2 on the apex, where the second tangent to the arc is parallel to the longitudinal direction of the implant. An arc beginning at the aforementioned points P1 and P2 and having tangents at the points common to the first and second tangents, forms a curved apex with a radius of curvature R1, a lower length S, and a lower radius r, which is created at the bottom of the groove between two adjacent helixes or coarsenesses.
