DELIVERY SYSTEM FOR BONE GROWTH PROMOTING MATERIAL

摘要

A delivery system that includes a bone growth promoting material encapsulated within a water absorptive gelatinizable covering is used to promote bone growth in order to repair a bone defect and/or strengthen a weakened bone region. The delivery system may be shaped and sized in order to fit within a bleeding wound (e.g. one that is formed in the gingiva when a tooth is extracted). The covering may be formed of a gelatinizable gauze that fonns a gel-like material when moistened with water. The delivery system is contained within a moisture resistant package prior to use. Alternatively, the delivery system comprises a bone growth promoting material and thickening agent contained within a syringe that, upon adding water, form a is viscous gel or stiff putty.
