Abstract
A tooth restoration system for insertion into a tooth upon which root canal therapy has taken place. The system comprises a post, a core and a crown wherein the post is formed from a fibre-reinforced composite material and the core and crown are formed from a ceramic or a polymer/ceramic composite material. The fibre-reinforced composite material is molded to the root canal shape while still in a uncured or partially cured state so that it molds to the root canal. The post is then finally cured and the core and crown built up on the post to form the dental implant. The fibre-reinforced composite material comprises a polymeric matrix and a reinforcing fibre component embedded within the matrix.
Claims5
A method of preparing a dental prosthesis comprising a post, a core and a crown for restoring a tooth upon which root canal therapy has taken place, the method comprising the steps of:
- (a) creating a post from an uncured or partially cured fibre-reinforced composite material comprising a polymeric matrix and a reinforcing fibre component embedded within the matrix;
- (b) molding a lower end of the post to fit the root canal void;
- (c) curing the post;
- (d) forming a core onto the upper end of the post from a ceramic or polymer/ceramic composite material;
- and
- (e) forming a crown around the core from a ceramic or polymer/ceramic composite material and shaping the crown to simulate the lost tooth.
A method of preparing a dental prosthesis comprising a post, a core and a crown for restoring a tooth upon which root canal therapy has taken place, the method comprising the steps of:
- (a) creating a mold of the tooth upon which root canal therapy has taken place;
- (b) creating a temporary post approximating the shape of the intended post;
- (c) creating an index around the temporary post;
- (d) removing the temporary post and filling the mold with an uncured or partially cured fibre reinforced composite material comprising a polymeric matrix and a reinforcing fibre component embedded within the matrix;
- (e) curing the post while applying a vacuum;
- (f) forming a core onto the upper end of the post from a ceramic or polymer/ceramic composite material;
- and
- (g) forming a crown around the core from a ceramic or polymer/ceramic composite material and shaping the crown to simulate the lost tooth.
