Simple solutions For difficult situations

Small class IV restorations are always a challenge cause if we want to disguise them we need to make a big bevel removing enamel that, as a must, we always like to protect. New materials and opaquers allow us to make these restorations in an easy way with less effort.

To bond we will use a universal adhesive but prior we etch the enamel cause in anterior restorations this tissue is the more predominant and the adhesive will perform better with this approach.

Conclusions

Universal composite is here to solve a wide range of restorative situations. Classically we make polychromatic restorations in anterior teeth or make big preparations to disguise fracture lines but now, this new material and opaque composite allow us to face these situations in an easier way. Handling, mimetic and enough colors to cover most of the clinical situations in anteriors and posteriors makes this material really interesting for daily use in the dental office.
