Material
this composite is a tried-and-tested veneering system that offers
several advantages over hybrid composite materials with regard to
wear, handling, plaque resistance and surface gloss. this can be
attributed to the high proportion of inorganic fillers in the nano-
scale range. Furthermore, the matrix is based on a urethane dimeth-
acrylate (UDmA), which is distinguished for its toughness, which is
higher than that of its predecessors or the frequently used Bis-
GmA.
in order to achieve a non-sticky, homogeneous consistency and a
low-shrinkage system, a special prepolymer was developed, which,
in turn, is based on nanofillers and the new UDmA. the result is a
virtually homogeneous material, which may well be called a micro-
filled composite.
Physical properties of SR Adoro
the inorganic microfillers together with an innovative matrix impart
homogeneous structure to the material. the coordinated ratio
between these two components provides the best physical
properties and promotes a high resistance against discolouration,
plaque accumulation and wear.
Esthetic properties of SR Adoro
Highly esthetic results can be achieved even if a straightforward,
basic layering procedure is used. even the basic sR Adoro material
exhibits an opalescent effect, which equals that of the natural
tooth. Aspects such as brightness and chroma and/or opacity and
translucency were taken into consideration for the colouration of
sR Adoro. these characteristics are apparent in the individual com-
ponents and endow the material with its highly esthetic properties.
