The mechanical and optical properties of different transparent vinyl polysiloxane materials used for guided composite resin injection technique

Significant variations exist in the mechanical and optical properties of transparent VPS materials, with ZHERMACK exhibiting superior mechanical properties and DELIAN superior optical properties. The optical properties declined significantly with increasing thickness. Transparent VPS material with higher mechanical properties can enhance the restoration accuracy of G-CRI technique, while thicker index or that fabricated using lower translucent materials necessitate longer exposure times for complete polymerization. Additionally, compressive modulus and light irradiance can be predicted using Shore A hardness and translucency, respectively.
