Self-Healing dental restorative formulations and related methods
First Claim
1. A dental restorative formulation, comprising:
- a first additive comprising a first capsule including a radical initiator; and
a second additive comprising a second capsule including one or more monomers and a radical accelerator, wherein the dental restorative formulation is polymerized to form a composite and upon the occurrence of a disturbance in the composite said first capsule and said second capsule rupture such that said radical accelerator decomposes said radical initiator of said first capsule to polymerize said one or more monomers of said second capsule thereby healing the composite.

Abstract
Dental restorative formulations comprising two additives incorporated into the continuous phase of a dental material. One additive contains a capsule with a radical initiator. The other additive contains a capsule with one or more monomers and a radical accelerator. The dental restorative formulation is applied and polymerized to form a composite. When a disturbance occurs in the dental composite, the capsules of the additives rupture so that the radical accelerator of the second capsule decomposes the radical initiator of the first capsule to polymerize the one or more monomers of the second capsule thereby healing the dental composite. The radical accelerator controls the rate of decomposition of the radical initiator.

13. A method of forming a dental restorative formulation, comprising the steps of:
-
providing a dental material; adding a first additive to the dental material, wherein the first additive comprises a first capsule including a radical initiator; introducing a second additive to the dental material, wherein the second additive comprises a second capsule including one or more monomers and a radical accelerator; applying the dental restorative formulation; polymerizing the dental restorative formulation to form a dental composite; and rupturing the first capsule and the second capsule when a disturbance occurs in the dental composite, wherein the radical accelerator of the second capsule decomposes the radical initiator of the first capsule to polymerize the one or more monomers of the second capsule thereby healing the dental composite.
