[Paranasal sinus reconstruction with bioactive bone cement--a 5-year animal experiment study].
The newly developed bioactivated bone cement Palavital is composed of polymethylmethacrylate, glass fibers and bioactive glass ceramic. The superficially located glass ceramic particles offer the possibility of true bonding of the bone cement to the bony implantation bed. Reconstruction of the frontal sinuses and the skull was performed on 9 dogs. The follow up was 14 days to 5 years. The implants were checked by tomography and histology. All implants were tolerated without any inflammatory reaction. The bond between bone and implant was demonstrated. Palavital seems to be an improvement on bone cement on a polymethylmethacrylate base.
