An Evaluation of Skeletal Attachment to LTI Pyrolytic Carbon, Porous Titanium, and Carbon-coated Porous Titanium Implants

Clinical Orthopaedics and Related Research, 1984
Porous titanium, carbon-coated porous titanium, and low-temperature isotropic (LTI) pyrolytic carbon transcortical implants were placed in the femora of mongrel dogs. Mechanical and histologic analyses were performed in specimens that remained in situ for six months.

Subantral augmentation with porous titanium in experiment and clinic

Stomatologiya, 2016
The article discusses the use of porous titanium for subantral augmentation. Experimental study was conducted on 12 yearling rams. Subantral augmentation using porous titanium was performed in 33 patients. In the control group consisting of 14 patients calcium phosphates and bone collagen based agents ("Bio-Оss" and "Collost") were used.

Mechanical properties and osteoconductivity of porous bioactive titanium

Biomaterials, 2005
Porous 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.

A novel characteristic of porous titanium oxide implants

Clinical Oral Implants Research, 2007
AbstractObjective: The anatase form of titanium dioxide (TiO2) is one of the most common crystalline forms of TiO2 and is normally produced by oxidation of titanium via thermal oxidation or anodizing. This crystalline form exhibits photocatalytic activity when it is irradiated with ultraviolet A (UVA) light. The aim of the current study was to analyze

Porous titanium alloy for fixation of knee prostheses

Journal of Biomedical Materials Research, 1974
AbstractA porous titanium alloy called void metal composite (VMC) was investigated for use in knee prosthesis fixation. The interfacial ingrowth fixation of VMC intrameduallary, subchondral, and variable density implants in goat femora was evaluated biomechanically and histologically at six weeks and five months.

Porous Titanium for Medical Implants

Multidisciplinary Materials Chronicles
Porous titanium and its alloys have shown immense promise as orthopedic and dental implant materials owing to their outstanding properties, namely tailorable porosity, the ability of blood vessels and bone ingrowth, the transport of nutrients and/or biofluids, and vascularization.

Micro/nanostructural porous surface on titanium and bioactivity

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2008
AbstractPorous surfaces can improve both early fixation and long‐term stabilization of implants by contrast with smooth surfaces. In this study, a microporous surface on titanium was prepared by acid etching and the size of micropores ranged from 1 to 60 μm.

Bioactive Porous Titanium: An Alternative to Surgical Implants

Artificial Organs, 2008
Abstract:  Porous titanium implants have been used to improve implant–bone attachment by the ingrowth of bone tissue within the porous structure. Despite the efficient bone adhesion of porous titanium implants, chemical bonds are required at bone–implant interface. These implants can become bioactive by a biomimetic precipitation process.
