Even so, due to the fact silicone is sticky, it'd be tough to build, with which a number of direct composite resin restorations is often put efficiently. It allows the polymerization in the composite resin throughout the clear silicone material and also the transfer in the tooth morphology within the waxed Solid to the mouth.
