Bulk Fill Posterior Restorations

New materials, such as bulk composites, allow us to improve our restorations making them look natural in a very fast way and without too many difficulties. In this case we present a class I made with new bulk fill material in only one increment obtaining a result feasible, teachable, and repeatable.

This approach allows us to dry the enamel while we maintain dentin without etching.

We apply two coats of universal adhesive system to auto-etch the dentin and bond to dentin and enamel properly.

Each adhesive layer must be blown with air and suction to eliminate solvent and obtain better results.

Checking occlusion, first we use a 400 micron paper to allow the stain to stick to the teeth.

The process for the restoration is really speeded-up by using this technique. From the initial situation to checking the occlusion including documentation, this case took 32 minutes.

Conclusions

Bulk fill materials are a very good option to make our daily dentistry easy and secure, giving our patients good long lasting results.
