Abstract: The present application relates to a radicular pivot wherein the apical end of the pivot has a hemispheric end with a continuous variation in the curvature between the cylindro-conical part and the apical end. The invention also relates to a drill for the preparation of the radicular chamber intended to receive such a pivot, as well as the system composed of a pivot and the matching drill.

Abstract: The present application relates to a radicular pivot including a rod having a threaded part wherein the distance between the internal conical envelope going through the roots of the threads, on the one hand, and the external conical envelope going through the crests of the threads increases towards the apical end, at least on a proximal part of the length of the thread.

Abstract: The invention relates to a device for storing tools, especially for storing drill bits, reamers, pivots, and dental implants, that includes a container for receiving the tools and a complementary closing mechanism that grips and closes the container by clipping onto it.

Abstract: The invention relates to an essentially parallelepiped-shaped tool storage device having at least two bodies affixed to one another by at least two fixing points of a pivot axis, one body forming the lid and the other being complementary to the lid-forming body. The lid-forming body is pivot-mounted and includes a pivot axis for opening the device.

Abstract: A radicular post cooperating with a resilient dental impression for use in preparing a cap to be fixed to a tooth having a post hole shaped to receive the post, each post having a conical part for entering the post hole and having a cylindrical part aligned on the longitudinal axis of the post and extending from the tooth when the post is seated in the post hole, the cylindrical parts of the posts having retention grooves circularly disposed around them, the parts of the posts being fully symmetrical about the axis; and the impression being formed of a cured resilient compound having a molded hole fitting the cylindrical part of each post, and the impression holes having resilient rings shaped to enter and fill the grooves in associated posts, the shapes of the grooves and rings and the resilience of the impression compound being selected such that the cylindrical parts of the posts can be removed from and re-positioned within the holes in the impressions without damaging the impressions and while achieving a
