Ivoclar Vivadent SR Nexco Paste - Manual (Page 5)

General note
as is generally known, composites have to meet different demands
due to country-specific uses. composite veneering materials show
specific characteristics and properties and their performance and
durability can therefore not be compared with that of other c&B
materials. the composite restorations may require clinical repair over
time, depending on the situation and the individual case. the
restorations can be repaired by means of microfilled composites, as
described in the section on "Subsequent adjustments" on page 58.
