Abstract

A crown for a damaged tooth is manufactured via metal injection molding and features an opening into which can be applied flowable dual-cure tooth colored material.

Claims (17)

1. A method of creating an interim restorative crown for a previously damaged anterior tooth comprising steps of:

forming a scaffold by metal injection molding (MIM) by creating a feedstock of finely powdered metal mixed with binder material, shaping and solidifying the feedstock using injection molding, and performing conditioning operations to remove the binder and densify the powdered metal;

fitting the scaffold about said anterior tooth wherein said scaffold defines a pocket, which pocket substantially conforms to the profile of said tooth; said scaffold having an opening therein;

fitting said scaffold to said tooth such that an empty space exists between the said scaffold and said tooth; and,

injecting flowable composite material into the said space through the opening.

2. The novel method of claim 1 , wherein said composite material is a dual-cure composite material.

3. The novel method of claim 1 , wherein said step of filling said scaffold overfills the opening; and further comprising the step of:

shaping said cured, dual-cure composite material.

4. The novel method of claim 3 , further comprising the step of:

polishing the cured dual-cure composite material.

5. The novel method of claim 1 , wherein the opening in the scaffold comprises an opening in a facial panel of said scaffold which further includes substantially all of said facial panel.

6. A method of creating an interim restorative crown for a previously damaged anterior tooth comprising the steps of:

providing a scaffold having a facial panel comprising an opening preformed into the facial panel;

fitting the scaffold about said anterior tooth wherein said scaffold defines a pocket, which pocket substantially conforms to the profile of said tooth;

adding a quantity of composite material to the pocket of said scaffold to bond the scaffold to the tooth and cover the opening of the facial panel of the scaffold;

curing, finishing and polishing said crown.

7. The method of claim 6 , wherein said composite material is a dual-cure composite material.
