ABSTRACT:
A picket for anchoring objects to an article is disclosed. The picket includes multiple helically-shaped members disposed about a common longitudinal axis and connected to one another. In one embodiment the object sought to be secured is placed between the end portions of the helically-shaped members and the picket is rotated into engagement with the surface thereby trapping the object sought to be secured between the helically-shaped members and a connecting means. The multiple helically shaped members increase the surface engaging force and permit the object sought to be anchored to be placed in a desired location on a surface and anchored without requiring the use of additional connecting means. In other embodiments an anchoring portion of the picket is integrally formed with, or fixed to, a generally cylindrical collar portion to provide both secure anchoring and lateral stability. A dental application for anchoring a dental prosthesis to a bone structure is also disclosed.
