Abstract
A dental post for securely retaining a dental restoration on a prepared tooth stub having a top surface and a bore extending therein. The dental post comprises a bulbous head and a shank. The shank is an elongated rod-like member having a first longitudinal axis, with the outside diameter of the shank measured along a second axis perpendicular to the first axis and being a predetermined dimension. The shank is arranged to be fixedly secured within the bore so that the bulbous head extends beyond the top surface of the prepared tooth stub. The bulbous head has an outside diameter measured along a third axis parallel to the second axis and is a predetermined dimension. The bulbous head has plural through passageways, e.g., a coronal passageway, and a transverse passageway that communicate with one another. The plural through passageways are for receipt of a setable securement medium which flows therein and about the surface of the head to secure the dental restoration to the post. A dental pliers is also disclosed for the safe handling and insertion of the dental post.
