adapt the first layer firmly (press into place) to ensure an effective bond between the Liner and lab composite and pre-
cure each segment for 20 seconds using a Quick curing light. the shade effect in the interdental area and cavity may be
increased by means of occlusal dentin orange. Slightly emphasize the marginal ridges and cusps with dentin.
Subsequently, begin the process of building up the cavity with dentin materials. make sure to provide adequate space for
the subsequent application of Incisal and Effect materials. the translucency of the restoration may be increased by means
of coloured transpa materials, such as transpa orange-grey and transpa brown-grey. Layer Sr nexco Paste layering
materials step by step and precure each individual layer. after building up and precuring the dental plateau, apply
characterizations with Sr nexco Stains and precure for 20 seconds. next, complete the restoration using Incisal and
transpa materials. the cusp tips and triangular ridges may be supplemented with a fine layer of opal Effect 3 and 4.
adapt firmly and create smooth, rounded transitions between the layers using Sr modelling instruments and synthetic
brushes.
Increase the shade effect in the interdental and cavity area with Occlusal Dentin. Outline the marginal ridges with Dentin and create a plateau with various Dentin materials.
Precure each intermediate segment for 20 seconds using the Quick curing light.
Apply characterizations with SR Nexco Stains, precure with the Quick and cover with Incisal and Transpa materials.
Design a lifelike occlusal morphology and subsequently precure all areas for 20 seconds using
Quick.
– It is essential to observe the stipulated curing depths and maximum layer thickness of the
individual materials during the layering procedure.
– If the maximum layer thickness is exceeded, break up large portions into several increments
and precure each increment for 20 seconds.
– SR Nexco Stains always have to be coated with layering material (e.g. Incisal, Transpa).
