Abstract
Titium is considered a biocompatible and corrosion resistant material. Recently possible titanium release from miniplates to the overlying tissues has been described. We have carried out a light microscopic study about possible changes in the soft tissues adyacent to 20 titanium miniplates after lower or upper jaw osteosynthesis. Possible morphologycal anomalies of the biomaterial were investigated hy scanning electron microscopy in 37 miniplates. We found granular deposits, probably titanium, in 16 soft tissues specimens (80%). Chronic inflamatory response was detected in 14 of 20 biopsies. Fragmentation orfissures in the material were observed in 21 of 37 miniplates (50, 8%), with superficial holes in 35,1% of the cases. No correlation of these microscopical findings with clinical complication was found. Our findings suggest that titanium wearing in organic environment is higher than described before. These findings are not correlated with clinical complication of the plates.
