Clinical Case: Bulk Fill Composite in Class I

Using 3M™ Scotchbond™ Universal Adhesive, 3M™ Filtek™ One Bulk Fill Restorative, and the 3M™ Sof-Lex™ Spiral Finishing and Polishing system.

About the Case

Replacing failing composite restorations can be easily done with the use of modern bulk fill composites.

The use of multilayering technique for restoring molars and premolars can be a tricky procedure due to the possibility of trapping bubbles between composite layers. In addition, it can result in unfavorable dental anatomy which may subsequently lead to functional problems. The use of bulk fill composites could reduce the risk of problems due to the simplicity of the process. As the placement process is shorter, we have more time to focus on the anatomy and function of our restoration.

In this case we show the replacement of a failing composite restoration in first left lower molar, replaced by a bulk fill composite restoration. Utilizing just a few steps and within only 31 minutes from start to finish, bulk fill composite is a great practice tool to use.
