Enhancement of Tech-Sil25 Maxillofacial Silicone Mechanical Properties after Artificial Weathering through Addition of Nanoparticles.

Purpose: To evaluate the effect of nanosilica and nanoalumina addition in Tech-sil25 maxillofacial silicone before and after exposure to artificial weathering conditions.

Materials And Methods: A total of 144 samples were divided into four groups, a control group ( = 12) and three test groups, nanosilica (NS) ( = 36), nanoalumina (NA) ( = 36), and a hybrid nanoparticle (HySA) ( = 60) at different weight percentages (1, 2, and 3 wt. %) was added to Tech-sil25.
