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.

Soft tissue grafts, packaged soft tissue grafts, and methods of making and using soft tissue grafts are disclosed. One soft tissue graft includes processed tissue material having first and second opposed surfaces. The first and second opposed surfaces are bounded by first and second edges. The first edge has a concave shape that curves toward the second edge. The second edge has a convex shape that curves away from the first edge. The first surface comprises a plurality of apertures. At least one of the apertures is formed from a multi-directional separation in the first surface. One method of making a soft tissue graft includes positioning a cutting die on a surface of tissue material, pressing the cutting die into the tissue material to cut the tissue material, and processing the cut tissue material to create processed tissue material.

Biodegradable antimicrobial films are provided that are solid at room temperature and substantially liquefy in situ after implantation into a mammal, such as a human patient. Methods of using the films to cover a medical device, such as a breast implant, prior to insertion into a subject are also provided.

A method of preparing a porous bone substitute is provided. The method includes preparing a ceramic paste including calcium phosphate-based ceramics, preparing a molded article formed of the ceramic paste based on a 3D rapid prototyping method, drying the molded article, and sintering the dried molded article.

Biodegradable antimicrobial films with improved surface and handling properties are provided that are solid at room temperature and substantially liquefy in situ after implantation into a mammal, such as a human patient. Methods of using the films to cover a medical device, such as a breast implant, prior to insertion into a subject are also provided. The biodegradable films may contain a drug to reduce inflammation or capsular contracture. Methods of making biodegradable films are also provided.

The present invention relates to a membrane comprising at least one positively charged, synthetic, hydrophobic polymer, at least one hydrophilic polymer and at least one plasticizer; wherein said membrane is flexible and is capable of supporting at least one of cell adherence, cell proliferation or cell differentiation. The invention further relates to use of a membrane of the invention in the preparation of an implantable devices including cell delivery systems, cell growing surfaces and scaffolds. The invention further provides methods for promoting tissue regeneration in a defected tissue region applying membranes of the invention.

Various aspects described herein relate to compositions comprising silk fibroin particles and methods of using the same, as well as devices and methods of delivering such compositions. The compositions described herein are suitable for injection into a site of defect in a soft tissue to provide bulking and/or augmentation effect to the soft tissue.

An encapsulated three-dimensional (3-D) bone matrix composition for inducing bone growth includes a 3-D bone matrix, an oxygen carrier incorporated into the 3-D bone matrix, and an encapsulation material which encapsulates the 3-D bone matrix incorporated with the oxygen carrier. Methods are disclosed for preparing an encapsulated 3-D bone matrix that can be maintained in packaging.

The present invention relates to a membrane comprising at least one positively charged, synthetic, hydrophobic polymer, at least one hydrophilic polymer and at least one plasticizer; wherein said membrane is flexible and is capable of supporting at least one of cell adherence, cell proliferation or cell differentiation. The invention further relates to use of a membrane of the invention in the preparation of an implantable devices including cell delivery systems, cell growing surfaces and scaffolds. The invention further provides methods for promoting tissue regeneration in a defected tissue region applying membranes of the invention.

The present invention provides a plasticized dehydrated or freeze-dried bone and/or soft tissue product that does not require special conditions of storage, for example refrigeration or freezing, exhibits materials properties that approximate those properties present in normal hydrated tissue, is not brittle, does not necessitate rehydration prior to clinical implantation and is not a potential source for disease transmission. The invention replaces water in the molecular structure of the bone or soft tissue matrix with one or more plasticizers allowing for dehydration of the tissue, yet not resulting in an increase in brittleness of the plasticized product, and resulting in compressive and/or tensile properties similar to those of normal hydrated bone. Replacement of the chemical plasticizers by water prior to implantation is not required and thus, the dehydrated bone or soft tissue plasticized product can be placed directly into an implant site without significant preparation in the operating room.
