Dental Tribune Middle East & Africa No. 4, 2017

4 INDUSTRY Dental Tribune Middle East & Africa Edition | 4/2017 A Challenging Class II Restoration By Dr. Stergios Zafi riadis, DDS, Switzerland About the Case A cusp fracture on the lower second premolar brought this patient to the offi ce. The large amalgam res- toration was removed, and second- ary decay noted. Once the existing amalgam and decay were removed, the remaining tooth structure indi- cated a very large, very challenging Class II restoration was required. Challenge Traditionally, a restoration of this size would require an incremental placement technique in which sev- eral time consuming layers would be required. In addition, this adds to the chance of contamination of the tooth, or contamination between layers of composite. Bulk place- ment of Filtek™ Bulk Fill Posterior Restorative allows this restoration to be completed in one increment, making the procedure more time- effi cient. The 3M Difference Completing a restoration of this scale can be challenging. Filtek™ Bulk Fill Posterior Restorative enables one-step placement up to 5mm for fast and easy posterior res- torations.
