TH31407B - What is embedded in the thread of the bolt - Google Patents

Abstract

This invention relates to a spiral. Or large roughness arranged for what is implanted Especially with buried things Dental threading Or such roughness (i.e. outline), which consists of two wings, the radius on R at the top is formed by the intersection of such two wings, the lower radius r is formed at the bottom of the groove between the threads or the roughness that are adjacent Two The wing, which forms a V angle to the ranias, is perpendicular to the helix cross section Or rudeness and Perpendicular to the surface of the body Such schemes also have height D corresponding to fabrication, thread size or roughness will bear the following designation for 10 degrees less _ V less than _ 35 degrees R larger than 0.4 x D and where for 35 degrees less than _ V less than _ 55 degrees R larger than 0.2 x D in popular shapes The requirements are for 0.05mm less than _ D, less than _ 0.5mm and 25 degrees less than _ V less than _ 55 degrees, the radius on R larger than 0.2 x D, but smaller than D and which for 0.25mm less than _ D. Less than _ 0.5 mm and 10 degrees less than _ V, less than _35 degrees R larger than 0.4 x D but smaller than D. Figure 1.

Claims (1)

1. a large spiral or roughness arranged for something in which a bone is implanted. Especially with dental screwed implants Helix section Or such rudeness (Such as a scheme) consisting of two wings And the radial peaks on the imaginary R at the crest are formed by the intersection of the two such wings that define the transition point P1 between the straight wing and the curved crest. The first tangent through P1 is directed along the wing. Including the vertices P2 on the yor, which is tangent to the second arc. Will be parallel to the direction Lengthwise of what is buried The arc that begins in points P1 and P2.
