Some surface improvement and osseointegration
Suchý, T. ; Balík, Karel ; Sedláček, R. ; Sochor, M.
As a further perspective material to be used in orthopedics, glass fibers (R-glass, 21055 satin-woven fabric, VETROTEX, Saint Gobain, France) and polysiloxane matrix (M130, Lučební závody Kolín, Czech Republic) based composite materials have been investigated.

Porous composites based on siloxane resin for hard tissue replacements
Suchý, T. ; Balík, Karel ; Sochor, M. ; Černý, Martin ; Hulejová, H. ; Pešáková, V.
A composite material based on polysiloxane and first on glass fabrics was prepared. The composite samples were prepared with controlled open porosity, the sizes of which were in the range: i) 0,2-0,4 mm, ii) 0,4-0,6 mm, and iii) >0,6 mm. For further improvement of osseointegration, a powder hydroxyapatite, particle size of 0,005 mm in the amount of 10 wgt %. The effects of surface treatment and hydroxyapatite matrix additives on osseointegration were studied by methods in vitro and in vivo.
