Abstract
An easily removable dental post is disclosed. The dental post is provided with a cavity that when necessary to remove the dental post acts as a ream guide or to engage a removing tool such as an Allen wrench. The cavity allows marking of the post through the use of radio-opaque material and the efficient curing of light-curable adhesive.
