Abstract

A periodontal structure regeneration composition for treatment of periodontal disease is a mixture of particles of a bone growth material and free collagen. The periodontal regeneration composition is injected into the periodontal pocket through a needle. The composition may contain a thickener that increases the viscosity of the composition after the material has been injected into the periodontal pocket. The composition is available in pre-filled syringes offered in a kit that may also contain strips of surgical sponge or gauze that are sized to fit within a periodontal pocket, a tube of adhesive, a dental bur, a probe, a gauze placement tool, gauze counter and a brush for cleaning the dental bur.

Claims (8)

1. A method of treating periodontal disease comprising the steps of:

placing a sponge into a periodontal pocket to distend the pocket and to cause hemostasis;

removing the sponge;

injecting into the periodontal pocket a mixture of a bone growth material and free collagen; and

subjecting the mixture to an infusion of energy, prior to injecting the mixture into the periodontal pocket;

wherein the steps of placing, removing, injecting, and subjecting are all done without incisions in gingival tissue surrounding the periodontal pocket.

2. The method of claim 1 wherein the infusion of energy is provided by heating the mixture.

3. The method of claim 2 wherein the infusion of energy is provided by exposing the mixture to microwave radiation.
