Abstract
Dental restorative formulations comprising an additive material and a capsule incorporated into the continuous phase of a dental material. The additive material includes one or more alkoxy groups and one or more vinyl groups. The capsule includes a catalyst and a molecule with one or more silanol groups. The dental restorative formulation is applied and polymerized to form a composite. When a disturbance occurs in the dental composite, the capsule ruptures so that the catalyst initiates a condensation reaction between the molecule with one or more silanol groups and the one or more alkoxy groups thereby healing the dental composite.
