Osteoinductive and Osteoconductive Biomaterials

2020
With combinatorial approaches getting stronger to design materials with better functionalities and compatibility for restoring bone tissue, it is becoming important to understand the progress and evolution of existing and newly designed materials. For being clinically usable, they should have features that address the biomechanical, biochemical, and ...

Bioactive films on metallic surfaces for osteoconduction

Journal of Biomedical Materials Research Part A, 2008
AbstractA fast and effective electrochemical method was developed to make a dense calcium phosphate films on titanium and stainless steel for hard tissue replacement. The surfaces of titanium and stainless steel were cathodically treated in an electrochemical cell. By controlling the treatment parameters, a film of 100‐nm thickness was deposited on the

Osteoconductive Composite Grouts for Orthopedic Use

Annals of the New York Academy of Sciences, 1988
A composite of HA particulate and calcium sulfate hemihydrate has been developed. When this dry material is mixed with either sterile saline or water, the resulting mixture begins to gel. While in the gel or dough state, the composite can be manually inserted or injected under pressure into a bone defect where it sets in situ.

Current Understanding of Osteoconduction in Bone Regeneration

Clinical Orthopaedics and Related Research, 1998
Bone tissue is osteoconductive. In particular, cancellous bone with its porous and highly interconnected trabecular architecture allows easy ingrowth of surrounding tissues. When placed in an osseous environment, living tissue for the host bed migrates into the cancellous structure, which results in new bone formation and incorporation of that ...

BOP: Biocompatible osteoconductive polymer: An experimental approach [PDF]

Clinical Materials, 1994
BOP (biocompatible osteoconductive polymer) is a material proposed for osteosyntheses and for filling of bone defects in orthopaedics, neurosurgery and stomatology. It is a composite made of a copolymer of N-vinylpyrrolidone and methylmethacrylate, of polyamide-6 fibers and of calcium gluconate.

Osteoconductivity of Porous Titanium Structure on Implants in Osteoporosis

Journal of Dental Research, 2021
In compromised bone conditions such as osteoporosis, developments of the implant surface are necessary to secure the stability of implants. This study investigated the effect of the surface porous titanium structure (PS) on the osseointegration of implants in osteoporotic bone.

Properties of Osteoconductive Biomaterials: Calcium Phosphates

Clinical Orthopaedics and Related Research, 2002
Bone is formed by a series of complex events involving the mineralization of extracellular matrix proteins rigidly orchestrated by cells with specific functions of maintaining the integrity of the bone. Bone, similar to other calcified tissues, is an intimate composite of the organic (collagen and noncollagenous proteins) and inorganic or mineral ...

Nonallograft Osteoconductive Bone Graft Substitutes

Clinical Orthopaedics and Related Research, 2002
An estimated 500,000 to 600,000 bone grafting procedures are done annually in the United States. Approximately (1/2) of these surgeries involve spinal arthrodesis whereas 35% to 40% are used for general orthopaedic applications. Synthetic bone graft substitutes currently represent only 10% of the bone graft market, but their share is increasing as ...

Osteoconductive Capacity of Hydroxyapatite Implanted Into the Skull of Diabetics

Journal of Craniofacial Surgery, 2011
Diabetes mellitus can cause various diseases, including loss of bone mineral density as a characteristic manifestation of osteoporosis. In this condition, bone is more vulnerable to pathologic fractures that can be treated by implantation of biomaterial grafts.

An osteoconductive collagen/hyaluronate matrix for bone regeneration

Biomaterials, 1999
A new type of collagen-hyaluronate (COL/HA) matrix was synthesized by cross-linking collagen fibers with modified hyaluronate polymers bearing active formyl groups. The resulting matrix is a three-dimensional scaffold consisting of interconnected pores with an average size of 40 microm and a high pore volume/surface area ratio.
