Dentin / Incisal layering
The layering procedure of the individual SR Adoro pastes is carried out in accordance with the layering diagram (shade
guide layering).
Adapt the first layer firmly (press into place) to ensure an effective bond between the composite and the opaquer surface
and precure each segment for 20 seconds using a Quick curing light. Cervical or Deep Dentin material may be applied in
a half-moon shape to cervical areas, pontics and crown margins that are thinning towards the metal. Adapt firmly and
create smooth, rounded transitions between the layers (Cervical – Dentin – Mamelon – Incisal) using SR modelling
instruments or synthetic brushes.
After that, build up the dentin layers step by step and precure each segment for 20 seconds. The shade effect in the
interdental area may be enhanced by means of chromatic materials, such as Occlusal Dentin orange. Design the dentin
core in such a way that the mamelon shape remains outlined. Make sure to provide adequate space for the subsequent
application of the Incisal and Transpa materials. The mamelons can be individually designed with either Mamelon material
or SR Adoro Stains. After that, the restoration is completed layer by layer using Incisal and Transpa materials. The coordi-
nated consistency of the material ensures that modelled contours are maintained and enables easy layering. The Incisal
materials are coordinated with the Dentin materials so that delicate transitions can be designed. Subsequently, precure
each segment for 20 seconds using the Quick.
Stabilize the pontic area with Deep Dentin and apply Cervical material in a half-moon shape in the cervical area.
– It is essential to observe the stipulated curing depth 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.
Apply the first layer on the Opaquer firmly, build up step by step, and precure.
