Bone substitute material
A biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material having a sintered CAP core and a closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core, wherein the closed epitactically grown layer of nanocrystalline HAP deposited on the external surface of the sintered CAP core has a homogeneous coarse external surface comprising flat crystal platelets, which shows an enhanced osteogenic response, a method of promoting bone formation, bone regeneration and/or bone repair by implanting the biphasic calcium phosphate/hydroxyapatite (CAP/HAP) bone substitute material, and a process of preparation thereof.
BIOMEDICAL MATERIALS
A synthetic calcium phosphate-based biomedical material comprising gadolinium. The material may comprises a compound having the general chemical formula: Ca.sub.10yGd.sub.y(PO.sub.4).sub.6x(SiO.sub.4)x(OH).sub.2x+y where 0<x<1.3 and 0<y<1.3.
METHOD FOR COATING CALCIUM SILICATE FOR PREPARING BONE GRAFTING MATERIAL HAVING IMPROVED BIOCOMPATIBILITY
The present invention relates to a method for preparing a glass-ceramic composite, in which a bioactive material is uniformly coated on the surface of a ceramic molded body; a glass-ceramic composite, in which a bioactive material is uniformly coated on the surface of a ceramic molded body; a bone grafting material comprising the glass-ceramic composite; and a bone grafting kit comprising the glass-ceramic composite.
Biocompatible molded part
The invention relates to a biocompatible molded part for supporting new bone formation, in particular the reformation of a jaw bone or a jaw bone portion in a mammal, preferably a human, wherein the molded part is suitable to be placed on the jaw bone and is designed as a solid body. The invention also relates to a composition for producing a biocompatible molded part, a method for producing a biocompatible molded part, a use of a biocompatible molded part and a kit comprising a plurality of molded parts.
Implants having a high drug load of an oxysterol and methods of use
Provided is an implant configured to fit at or near a bone defect to promote bone growth, the implant comprising: a biodegradable polymer in an amount of about 0.1 wt % to about 20 wt % of the implant and an oxysterol in an amount of about 20 wt % to about 90 wt % of the implant. The implant has a high oxysterol load. Methods of making and use are further provided.
BONE SUBSTITUTE AND METHOD FOR PRODUCING BONE SUBSTITUTE
This bone substitute includes a calcium phosphate-type porous ceramic body having spherical voids; and a bioactive glass layer that is formed of a bioactive glass, coats an inner surface of each of the voids and has a thickness of less than 50 m. The porous body has communication holes through which the voids communicate with each other.
Bioimplant with evanescent coating film
To provide a bioimplant capable of controlling a rate of an antibacterial agent and an antibiotic to be eluted from the coating film. An evanescent coating film made of a calcium phosphate-based material having crystallinity of 90% or less is formed at a predetermined area of the bioimplant and an antibacterial agent or an antibiotic is contained in the coating film. If necessary, a metal oxide layer made of a metal oxide having an isoelectric point of less than 7 is formed on the bioimplant thereby suppressing adhesion of bacteria.
Infused particles
A method of making infused bone particles employs the following steps: cutting or shaving whole bone into bone particles, washing the bone particles, demineralizing or decalcifying at least partially the whole bone or bone particles and infusing the bone particles with a supernatant of biologic material or a polyampholyte cryoprotectant or a combination of both to create infused bone particles. The step of infusing includes exposing the bone particles to a negative pressure or vacuum to draw the supernatant and/or the polyampholyte cryoprotectant into the bone particles, or alternatively, exposing the demineralized whole bone to a positive pressure to drive the supernatant and/or the polyampholyte cryoprotectant into the bone. The resultant method creates an infused bone grafting composition having bone particles taken from whole bone, demineralized or decalcified at least partially and infused with one or more of a supernatant of biologic material or a polyampholyte cryoprotectant or both.
Compositions and methods for treating bone defects
A bone graft composition includes a biologically-resorbable cement and a plurality of processed bone particles, where each of the bone particles have a shape configured to interconnect with adjacent bone particles. A method for treating a bone defect using the bone graft compositions includes providing the bone graft composition and administering an effective amount of the bone graft composition to a site of a bone defect in a subject. Kits including a biologically-resorbable cement powder and a plurality of processed bone particles are also provided.
Lipid compositions containing bioactive fatty acids
Provided herein is technology relating to lipid compositions containing bioactive fatty acids and particularly, but not exclusively, to compositions and methods related to the production and use of structured lipid compositions containing sciadonic and/or pinoleic acid alone or in combination with other bioactive fatty acids including, but not limited to, eicosapentaenoic acid, docosahexaenoic acid, conjugated linoleic acid, and non--oxidizable fatty acid analogues such as tetradecylthioacetic acid.
