An osteoconductive collagen/hyaluronate matrix for bone regeneration
Biomaterials, 1999A 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.

Octacalcium phosphate: Osteoconductivity and crystal chemistry
Acta Biomaterialia, 2010Octacalcium phosphate (OCP), which is structurally similar to hydroxyapatite (HA), is a possible precursor of bone apatite crystals. Although disagreement remains as to whether OCP comprises the initial mineral crystals in the early stage of bone mineralization, the results of recent biomaterial studies using synthetic OCP indicate the potential role ...

Osteoconduction at porous hydroxyapatite with various pore configurations
Biomaterials, 2000To assess the histological response and the reinforcing effects of bone ingrowth within porous hydroxyapatite (HA) implants depending on pore geometry, four kinds of cylindrical-type with parallel linear pores phi50, 100, 300, 500 microm), one kind of sponge-type with irregular interconnecting pores (phi250 microm) and one cross-type with crossing ...

Osteoconductivity and Osteoinductivity of Puros® DBM Putty
Journal of Biomaterials Applications, 2010Bone graft substitutes have been developed due to the limited supply and morbidity associated with using autogenous graft material. Allogeneic demineralized bone matrix (DBM) has been used extensively as a clinical graft material because of its inherent osteoinductive and osteoconductive properties.

Osteoconductivity of Hydrothermal-Treated Valve Metals
Materials Science Forum, 2014Anti-corroded valve metals, such as Ti, Nb, Ta, and Zr have been used as metallic biomaterials. However, as untreated surfaces, they do not have high osteoconductivity, and surface coatings with bioactive substances are needed for the implantation into the bone.

Nasal Reconstruction Using an Osteoconductive Collagen Gel Matrix
Archives of Otolaryngology - Head and Neck Surgery, 1996Congenital malformations, granulomatous diseases, and trauma can all cause destruction of the nasal structural framework, resulting in functional nasal obstruction and altered facial cosmesis. Current methods of nasal reconstruction include cartilaginous and bony grafts, Silastic implants, and homograft only materials.

Mechanical properties and osteoconductivity of porous bioactive titanium
Biomaterials, 2005Porous bioactive titanium implants (porosity of 40%) were produced by a plasma-spray method and subsequent chemical and thermal treatments of immersion in a 5M aqueous NaOH solution at 60 degrees C for 24 h, immersion in distilled water at 40 degrees C for 48 h, and heating to 600 degrees C for 1 h.

Enhanced Osteoconductivity of Positively Charged Titanium Metal
Key Engineering Materials, 2011We previously found that a positively charged Ti metal has a higher apatite forming ability in vitro than a non-charged Ti metal. For in vivo analysis using a rabbit model, two types of Ti metal were examined: porous Ti metals heat-treated subsequent to a mixed acid treatment (MHs) and porous Ti metals not heat-treated subsequent to the same mixed acid
