Description
High Strength LSi Restorations:
With a strength of minimum 400mpa (±60MPa), Nebula LSi can withstand high-precision cutting, reducing the difficulty of processing (and manual adjustments) even for ultra-thin veneers and other restorations, enhancing the material’s required strength and safety in the oral cavity.
Ultra-thin Minimally Invasive:
Star can be milled as thin as 0.2mm for ultra-thin veneers, requiring minimal tooth preparation. It is an ideal material for chairside minimally invasive restorations, preserving the maximum healthy natural teeth for patients.
