Compomers are dental restorative materials that are a composite of composite resins and glass ionomer cements. They are biocompatible and release fluoride, making them effective for restoring anterior teeth. Compomers have aesthetic qualities allowing for color selection, are photopolymerizable for quick curing, and have acid-base properties. However, they have low resistance to direct chewing forces and require a careful mixing technique when first applied. Common brands include Dyract and Hytac.

3.  As can be used ?
The compomers are used to aesthetically
restore anterior teeth where are not forces
chewing .

4.  advantages:
 Biocompatible at dentin structures.
 -Effect anticariogenic: the release of fluoride.
 -Aesthetic: Allows selection of the desired color, using the
color guide.
 Photopolymerizable: reducing working time.
 be can photocuring and have an acid additional base.
 Excellent handling characteristics

5. Disadvantages :
- Presents Microfiltration , however, this does not
contraindicate their use, because it presents a good
behavior by releasing fluoride.
-Low impact resistance direct masticario.
-Mixing technique demanding for their sensitivity to
moisture in the first minutes.
