Biomaterials

Category: Research Interests Published on Wednesday, 05 March 2014

We are currently working in biomaterials synthesis and characterization main focusing on

  • Synthesis and characterization of bioactive glass-ceramics. 
  • Preparation of composite materials with bioactive properties (scaffolding-ceramic)
  • Polymers and especially biodegradable polymers
  • Study bioactivity (bioactivity) in vitro
  • Interaction of materials and cells

 

Biomaterials Rersearch

Bioactive materials develop a strong bond with living tissues through a carbonate-containing hydroxyl-apatite layer, similar to that of bone. 
Bioactive materials such as glasses and glass-ceramics have been successfully used in the restoration of osseous defects and in the promotion of a “new attachment” of soft tissues on tooth surfaces
The aim of our study is the in vitro investigation of the surface structure changes - after exposure in a simulated body fluid (SBF) - of dental ceramics used in metal-ceramic restorations, coated with: 
I) a bioactive glass 
II) a mixture of bioactive glass and conventional dental ceramic (1:1)

FTIR is used mainly for the identification of the presence of biological apatite on the surface of the specimens.
