Abstract
A dental prosthetic device and method of making and installing the device, the device being a nonmetallic dental post for tooth restoration, the post being fabricated in a mold from a fiber reinforced, ceramic polymer composite, the post having an anchor portion installed in a drilled and reamed post hole with an adhesive and a mounting head portion that is built up with a core material for bonding to a restoration, the post restorative having structural and composition characteristics similar to a natural tooth.
Claims22
A dental post for use in mounting a permanent tooth restoration comprising:
- an elongated post member fabricated of a nonmetallic composition having an anchor portion adapted to seat in a prepared tooth canal and a mounting portion adapted to construct a tooth core for mounting a permanent tooth restoration on the installed post wherein the post-member is prefabricated in a mold from a fiber-reinforced composite material having a strength and flexibility approximating natural tooth material, wherein the elongated post member is fabricated from a polymer composite material forming a unitary, flexible mounting structure having a flexible strength of approximately 1000 megapascals and is fabricated in a mold from a fiber-reinforced composite material having a glass fibers in a methacrylate polymer matrix.
A method of dental restoration of a tooth using a nonmetallic post having an anchor portion and a head portion comprising the steps of:
- a.) structurally preparing the tooth for drilling a post hole;
- b.) selection one of a plurality of prefabricated nonmetallic posts having a fiber-reinforced composite material having a strength and flexibility approximating natural tooth material wherein the elongated post member is fabricated from a polymer composite material forming a unitary, flexible mounting structure having a flexible strength of approximately 1000 megapascals and is fabricated in a mold from a fiber-reinforced composite material having glass fibers in a methacrylate polymer matrix;
- c.) drilling a post hole conforming to the anchor portion of the selected nonmetallic post;
- d.) injecting a resin adhesive into the post hole;
- e.) coating the anchor portion of the nonmetallic post with an adhesive;
- f.) installing the post in the hole;
- g.) building a restoration core on the head of the post;
- h.) shaping the restoration core to receive a restoration;
- and,
- i.) adhering a restoration to the core and head of the post.

- c. selecting one of the elongated prefabricated posts;
- d. drilling a post hole conforming to the anchor portion of the nonmetallic post;
- e. injecting a resin adhesive into the post hole;
- f. coating the anchor portion of the nonmetallic post with an adhesive;
- g. installing the post in the hole;
- h. building a restoration core on the head of the post;
- i. shaping the restoration core to receive a restoration;
- and,
- j. adhering a restoration to the core and head of the post;
- wherein the step of coating the anchor portion of the nonmetallic post includes a preliminary step of etching the anchor portion of the post.
