<p>The present invention relates to a dental prosthetics and more particularly to an improved support post (18), having a centrally convergent shank portion (1), for securing a dental prosthesis, such as an artificial crown, to the root of a tooth. The invention further relates to a method and device for strengthening a tooth and root from which the nerve has been removed and specifically to a dental post which provides centering for the forming of a bracing filler to internally reinforce the walls of pulpless roots while providing for the support of an artificial prosthesis. The invention further provides for a secondary reinforcing device surrounding the central dental post and also being capable of following the contours of the tooth root. This secondary strengthening and reinforcing element is a flexibly coiled wire (112) of a generally helicoid shape, which also serves as a matrix for the luting of composite filler.</p> |
