Provided herein are compositions and their methods of use to adhere (e.g., in wet and dry environments) a variety of materials together.

GLASSES, CEMENTS AND USES THEREOF

Various embodiments of tantalum- and/or niobium-containing glasses and cements as well as uses thereof are described herein. For example, in an embodiment, the glasses comprise a transition metal pentoxide such as tantalum pentoxide and/or niobium pentoxide present in the glass in an amount of less than 2.0 mol %, based on the total composition of the glass, glass polyalkenoate cements prepared from such glasses and uses of such cements, for example, for sternal closure or fixation, stabilization and/or repair of a fracture in a bone in the wrist, elbow, knee, shoulder, spine and/or hip.

Injectable, biodegradable bone cements and methods of making and using same

Compositions of, methods of making, and methods of using alkaline earth phosphate bone cements are disclosed. A bone cement composition includes a powder comprising a basic source of calcium, magnesium, or strontium, a setting solution comprising H3PO4 and a buffer, and a biocompatible polymer that is incorporated into the setting solution. The powder is mixed with the setting solution to form a bone cement paste that either (a) sets into a hardened mass, or (b) is irradiated with electromagnetic radiation to form dry powders, the dry powders then being mixed with a second setting solution to form a radiation-assisted bone cement paste that sets into a hardened mass.

Method for controlling work time for forming shape of biphasic self-setting calcium phosphate

Biphasic self-setting calcium phosphate (SSCP) used for bone graft material and dental material applications having shape formability, shape retentivity, and bone replacement properties in addition to biocompatibility, safety, non-infectiousness, and absence of outflow, wherein the work time for forming the shape of a kneaded material obtained by kneading biphasic SSCP powder and biphasic SSCP liquid is controlled. A method for controlling the work time for forming the shape of biphasic SSCP in which the moldable work time from the start of kneading to the setting of the kneaded material is adjusted to within a range of from 10 seconds to 600 seconds by kneading a biphasic SSCP powder and biphasic SSCP liquid, the biphasic SSCP powder comprising tetracalcium phosphate and -tricalcium phosphate and the biphasic SSCP liquid comprising a phosphoric acid aqueous solution containing a calcium component.

HIGHLY LOADED METAL OXIDE MATERIALS BY SELF-ASSEMBLY FOR EXTENDED BIOLOGICALLY ACTIVE MOLECULE RELEASE IN MEDICAL AND DENTAL APPLICATIONS

A biocompatible composite material for controlled release is disclosed, comprising a biocompatible metal oxide structure with a loaded network of pores. The pore network of the biocompatible composite material is filled with a uniformly distributed biologically active micellizing amphiphilic molecule, the size of these pores ranging from about 0.5 to about 100 nanometers. The material is characterized in that when exposed to phosphate-buffered saline (PBS), the controlled release of the active amphiphilic molecule is predominantly diffusion-driven over time.

Monolithic bodies of sintered chemically bonded ceramic (CBC) biomaterial prepared ex vivo for implantation, preparation and use thereof
10117964 · 2018-11-06 · ·

The present invention generally relates to the use of pre-formed bodies of Chemically Bonded Ceramics (CBCs) biomaterial for implantation purposes wherein the bodies are prepared ex vivo allowing process parameters to be optimized for desired long term properties of the resulting CBC biomaterial. More particularly, the pre-formed CBC material bodies of the present invention are sintered. The pre-formed body of CBC material is machined to the desired geometry and then implanted using a CBC cementation paste for fixation of the body to tissue. The invention also relates to a method of preparing pre-formed bodies of CBC biomaterial for implantation purposes, methods of preparing an implant thereof having desired geometry, and a method of implantation of the implant, as well as a kit for use in the method of implantation.
