Porous Titanium Implants: A Review
Advanced Engineering Materials, 2018Titanium and its alloys are commonly used in almost all disciplines of medicine because of their sufficient biocompatibility and meeting of mechanical requirements. However, dense metallic biomaterials represent only an interfacial connection with host tissue, may develop stress shielding which causes ingrowth of the fibrous tissue, and are prone to ...

Porous Tantalum and Titanium in Orthopedics: A Review
ACS Biomaterials Science and Engineering, 2019Porous metal is metal with special porous structures, which can offer high biocompatibility and low Young's modulus to satisfy the need for orthopedic applications. Titanium and tantalum are the most widely used porous metals in orthopedics due to their excellent biomechanical properties and biocompatibility.

Osteoinduction of porous bioactive titanium metal
Biomaterials, 2004This is the first report of bone induction in a non-osseous site by titanium metal, which has long been recognized as a non-bioactive material. After undergoing specific chemical and thermal treatments, porous bioactive titanium induced bone formation without the need of additional osteogenic cells or osteoinductive agents.

Direct calciothermic reduction of porous calcium titanate to porous titanium
Materials Science and Engineering C, 2018A metallurgical material integration concept, using porous calcium titanate (CaTiO3) as raw material, was put forward for preparation of metallic titanium powder and porous titanium by calciothermic reduction. Porous metallic titanium was prepared by calcium vapor reduction at 1273 K for 6 h with two types of interconnected pores in titanium samples ...

Highly porous titanium scaffolds for orthopaedic applications
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2010 AbstractFor many years, the solid metals and their alloys have been widely used for fabrication of the implants replacing hard human tissues or their functions. To improve fixation of solid implants to the surrounding bone tissues, the materials with porous structures have been introduced. By tissue ingrowing into a porous structure of metallic implant,

Tailoring the Porous Hierarchy of Titanium Phosphates
Langmuir, 2006First hierarchical titanium phosphate (TiPO) materials with multiple porosities of different lengths (meso-macroporous and meso-macro-macroporous) were synthesized by the self-formation process. The further tuning of the porous hierarchy by using the poly(ethylene oxide) surfactant technique was demonstrated.

Bone grajis are invaluable players in the arena of regenerative dentistry. Reconstitution of the lost bone was the objective behind the introduction of these bone grajis based on the properties of osteoconduction. osteoinduction and os/eogenesis. Although autogenous bone grajis still uphold their reputation as gold standard.

Interface mechanics of porous titanium implants
Journal of Biomedical Materials Research, 1981AbstractThe interfacial shear properties of bone tissue growth into porous coated Ti‐6A1‐4V femoral implants have been examined as a function of the pore size of the porous surface. Three particle size range powders (297 μm, 420–500 μm, 595–707 μm) were used to fabricate cylindrical implants which were inserted into the femoral medullary canal of dogs ...

Osteoconductivity of Porous Titanium Structure on Implants in Osteoporosis
Journal of Dental Research, 2021In 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.

Porous titanium dental implants
Journal of Biomedical Materials Research, 1974AbstractTitanium implants have been designed which utilize a solid core and porous exterior. The technique for implants containing posts utilizes a cast chromium‐cobalt splint for fixation and the buried implants are held in place by the overlying gingiva until tissue growth into the porosity results in stabilization.Clinically successful post implants
