SHELF LIFE AND COLOR PROFILE OF RESIN COMPOSITIONS WITH SILVER NANOPARTICLES
Methods of forming antimicrobial resin compositions comprising silver nanoparticles are disclosed, wherein the resin compositions that are generated exhibit lower initial color, reduced color shift upon storage and reduced levels of spontaneous polymerization. Such methods generally comprise: combining a silver-containing material with a self-cure and dual-cure base resin in situ wherein the base resin does not contain a catalytic amine; and adding a catalytic resin to the mixture of the resin and silver-containing material in order to form the final cured resin. Antimicrobial polymeric materials formed by said methods are also disclosed.
Bioactive porous bone graft implants
Bioactive porous bone graft implants in various forms suitable for bone tissue regeneration and/or repair, as well as methods of use, are provided. The implants are formed of bioactive glass and have an engineered porosity. The implants may take the form of a putty, foam, fibrous cluster, fibrous matrix, granular matrix, or combinations thereof and allow for enhanced clinical results as well as ease of handling.
Method for producing an implant comprising calcium carbonate-containing composite powder having microstructured particles having inhibiting calcium carbonate
The invention relates to a method for producing an implant by means of a composite powder having micro structured particles having inhibiting calcium carbonate, wherein the composite powder is obtained by a method in that large polymer particles are joined to small calcium carbonate particles, wherein the calcium carbonate particles are obtained by a method in that calcium carbonate particles are coated with a composition which, in each case based on the total weight thereof, comprises a mixture of at least 0.1 wt % of at least one calcium complexing agent and/or at least one conjugated base which is an alkaline metal or calcium salt of a weak acid, together with at least 0.1 wt % of at least one weak acid.
REINFORCED BIOLOGIC MATERIAL
The present disclosure provides an implantable medical device comprising a composite graft material including a first biologic component, such as an acellular tissue matrix, and a second non-biologic component.
METHOD FOR USING AN ADHESIVE COMPOSITION IN BONE PRESERVATION AND AUGMENTATION
A method comprising the steps of applying an adhesive composition to a substrate bone repair region. The adhesive composition comprises a porous, biocompatible, biodegradable, resorbable, non-toxic, and polymerizable composition. The substrate bone repair region comprises a bone structure, implant or device surface, or tooth surface. The adhesive composition is cured to provide a polymerized adhesive composition resulting in repairing or augmenting the substrate bone repair region. The adhesive composition may be mixed with a bone graft material before application. The adhesive composition may be additionally applied to a barrier membrane that is placed over the substrate bone repair region where the adhesive composition or combination of adhesive composition and bone graft material is applied.
METHOD AND APPARATUS FOR TREATING BONE FRACTURES, AND/OR FOR FORTIFYING AND/OR AUGMENTING BONE, INCLUDING THE PROVISION AND USE OF COMPOSITE IMPLANTS
A composite implant comprising an injectable matrix material which is flowable and sellable, and at least one reinforcing element for integration with the injectable matrix material, the at least one reinforcing element adding sufficient strength to the injectable matrix material such that when the composite implant is disposed in a cavity in a bone, the composite implant supports the bone. A method for treating a bone, the method comprising: selecting at least one reinforcing element to be combined with an injectable matrix material so as to together form a composite implant capable of supporting the bone; positioning the at least one reinforcing element in a cavity in the bone; flowing the injectable matrix material into the cavity in the bone so that the injectable matrix material interfaces with the at least one reinforcing element; and transforming the injectable matrix material from a flowable state to a non-flowable state so as to establish a static structure for the composite implant, such that the composite implant supports the adjacent bone.
IMPLANTS HAVING A DRUG LOAD OF AN OXYSTEROL AND METHODS OF USE
Provided is a compression resistant implant configured to fit at or near a bone defect to promote bone growth. The compression resistant implant comprises a biodegradable polymer in an amount of about 0.1 wt % to about 20 wt % of the implant and a freeze-dried oxysterol in an amount of about 5 wt % to about 90 wt % of the implant. Methods of making and use are further provided.
METHOD AND APPARATUS FOR TREATING BONE FRACTURES, AND/OR FOR FORTIFYING AND/OR AUGMENTING BONE, INCLUDING THE PROVISION AND USE OF COMPOSITE IMPLANTS
A composite implant comprising an injectable matrix material which is flowable and settable, and at least one reinforcing element for integration with the injectable matrix material, the at least one reinforcing element adding sufficient strength to the injectable matrix material such that when the composite implant is disposed in a cavity in a bone, the composite implant supports the bone.

HYDROGEL COMPOSITIONS AND USES THEREOF
The present application provides compositions configured to be provided in a flowable, liquid form but that are configured to transition to a solid or semi-solid gel based upon a change in pH. The change in pH can arise from one or more materials utilized in the composition itself or based upon encountering an environment with a significantly different pH. The compositions are particularly suited for use as a teat sealant in non-human mammals, particularly cattle.
