Clinical Guide: Class II Restoration of First Premolar with Interproximal Decay

Originally published by The Arch: An Ultradent Blog

Cases requiring a sectional matrix system are far from rare for most dentists—but the nearly unlimited number of contributing factors can make each case unique. The Halo™ sectional matrix system is equipped to handle a wide variety of situations, allowing clinicians to provide long-lasting restorations amid nearly any circumstance. “I have used many sectional matrix systems over the years and found some that work better than others. With the Halo matrix system, it has all come together,” says Dr. James Wright. 

Dr. Wright gives credit to the specially formed contours of the matrices as well as the uniquely designed rings for the beautiful final restoration. “The Halo system limits the amount of clean up and the contacts are ideal,” he says.

adhesive, Mosaic™ universal composite shades A3 and EY were used to restore the tooth. The EY shade was placed to establish the interproximal wall to aid in a more aesthetic restoration.
