Tips regarding the different layers
It is advisable to apply highly opaque pastes, e.g. mamelon light, to the pontic rest to
ensure adequate shade stability. after that, layer these areas using margin and dentin
materials.
Before layering, avoid mixing and overlapping the pastes to prevent air from being
trapped. do not dilute the pastes with Sr modelling Liquid or low-viscosity
components. as a general rule, use only small amounts of Sr modelling Liquid.
Use the shaded transpa materials to complete and enhance the vitality in the incisal
area. transpa blue is suitable for the mesial and distal aspects.
Use mamelon materials to create a lifelike shade effect in the incisal third. they are
applied on the completed incisal area. create smooth transitions. avoid edges, since
they may look like stubs after polymerization and the mamelons may appear too
pronounced.
It is recommended to build up the veneer segment by segment (tooth by tooth), to
separate them from each other and then to precure. finally, the individual veneers are
joined.
opal Effect pastes provide a true-to-nature opalescent effect in the incisal third. opal
Effect 1 is applied to the cut-back dentin as extension of the dentin core and then
precured.
