Aims:
To investigate how Cosmesil M-511 HTV maxillofacial silicone elastomer's tear, hardness, and colour are affected by the addition of nanoscale silicone dioxide (SiO 2 ) and cerium oxide (CeO 2 ) filler.
Materials And Methods:
Nano SiO 2 and CeO 2 were added to the silicone base in concentrations of 5% by weight. Silicone with 0% nanofiller served as a control. The tear test was conducted according to ISO 34-1. A visual colour-measuring test was conducted According to ASTM D1535.
Statistical Analysis Used:
ANOVA test was used for statistical analysis. There was a significantly substantial increase in tear strength in all nano SiO 2 concentration groups.
Results:
Among the other groups, the 5% group displayed the highest mean values. According to spectrophotometric data, the material's translucency was significantly reduced with all nanofiller concentrations; however, this reduction could also be seen visually as a little intensification of colour.
Conclusions:
Mechanical properties like tear and hardness of M-511 silicone are greatly improved when reinforced with 5% nano SiO 2 ; however, there is a little visible colour shift.
