ABSTRACT:
A periodontal structure regeneration composition for treatment of periodontal disease is a mixture of particles of a bone growth material and free collagen. All particles are sized to be less than 1 mm in diameter. The periodontal regeneration composition is injected into the periodontal pocket through an 18 gauge 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.
