چکیده

titanium and its alloy are known as important load-bearing biomaterials. the major drawbacks of these metals are fibrous formation and low corrosion rate after implantation. the surface modification of biomedical implants through various methods such as plasma spray improves their osseointegration and clinical lifetime. different materials have been already used as coatings on biomedical implant, including calcium phosphates and bioglass. however, these materials have been reported to have limited clinical success. the excellent bioactivity of calcium silicate (ca-si) has been also regarded as coating material. however, their high degradation rate and low mechanical strength limit their further coating application. trace element modification of (ca-si) bioceramics is a promising method, which improves their mechanical strength and chemical stability. in this review, the potential of trace element-modified silicate coatings on better bone formation of titanium implant is investigated.

Carbon coating stabilized Ti(3+)-doped TiO2 for photocatalytic hydrogen generation under visible light irradiation.

Self-doping by Ti(3+) is a useful method to expand the light response of TiO2 into the visible light region. However, to obtain a stable Ti(3+)-doped TiO2 seems to be a challenge due to the easy oxidation of Ti(3+) during the heterogeneous reaction. Here, we propose a simple carbon coating route to stabilize the Ti(3+)-doped TiO2, in which both the Ti(3+) and precursor of the carbon coating lay...

Effect of Tricalcium Magnesium Silicate Coating on the Electrochemical and Biological Behavior of Ti-6Al-4V Alloys

In the current study, a sol-gel-synthesized tricalcium magnesium silicate powder was coated on Ti-6Al-4V alloys using plasma spray method. Composition of feed powder was evaluated by X-ray diffraction technique before and after the coating process. Scanning electron microscopy and atomic force microscopy were used to study the morphology of coated substrates. The corrosion behaviors of bare and...

Bioceramic Implant Induces Bone Healing of Cranial Defects

Autologous bone or inert alloplastic materials used in cranial reconstructions are techniques that are associated with resorption, infection, and implant exposure. As an alternative, a calcium phosphate-based implant was developed and previously shown to potentially stimulate bone growth. We here uncover evidence of induced bone formation in 2 patients. Histological examination 9 months postope...

Bioceramic Implant for Complex Maxillofacial Reconstruction: A Case Report

Reconstructive surgery of complex three-dimensional defects of the midface/maxilla following treatment of advanced squmous cell carcinoma of the maxilla is challenging. Primary or secondary reconstruction using autogenous bone grafts or alloplastic materials are standard procedures, however such procedures may be associated with complications. In particular secondary reconstructions often requi...
