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 time of adhesive, a dental bur, a probe, a gauze placement tool, gauze counter and a brush for cleaning the dental bur.

This invention provides aragonite- and calcite-based solid substrates for the repair, regeneration, enhancement of formation or a combination thereof of cartilage and/or bone, which solid substrates comprise or are made to ultimately comprise three phases, wherein each phase differs in terms of its chemical content, or structure, kits comprising the same, and methods of use thereof.

A system for multiphasic delivery of at least one growth factor at a treatment site comprises a delivery vehicle for releasing at least one growth factor in an initial release profile and a carrier for releasing at least one growth factor in a sustained release profile. The initial release profile releases at least one growth factor over a period of hours to days, wherein the growth factor is released in a large amount initially, with the remainder being released in progressively lower amounts. The sustained release profile releases at least one growth factor over a period of days to weeks, wherein the growth factor is released at a generally constant amount over such period. The system of the invention is particularly suited for applications on bioimplants. The invention also comprises methods and kits for multiphasic delivery of at least one growth factor. The invention also comprises calcium sulphate as a carrier for releasing at least one growth factor in both single and multiphasic systems for delivering at least one growth factor at a treatment site.
