Abstract
A dental post for retaining a dental restoration onto a tooth stub and a method for making dental post. The dental post includes a cylindrical body portion and a head portion which extends outwardly from the body portion. The body portion is inserted in a bore in the tooth and secured therein by cement. To improve cement retaining capacity of the dental post, there are provided on the body portion non-continuous raised portions, spaced by wide open gaps to retain large segments of thick segments of cement. The overall portion of the gap area surface is greater than that of the land area surface.
