"The 3DXR ring from Garrison Dental is a significant improvement on all previous rings; it is truly universal and I have not found any Class II restoration that it will not fit. The 3DXR has not flown across the room once! When used with the sectional matrices and WedgeWands (or A+Wedges), it helps to provide a tight anatomical contact area and highly predictable posterior composite restorations every time."
