The old saying that “no chain is stronger than its weakest link” is certainly true in dentistry. When working with crown and bridge, one of the primary complaints from dentists to dental technicians is that “the occlusion was high and it took a long time to adjust it clinically.”1 The restorative process for an indirect restoration includes many steps that, when not carefully executed, can contribute to this problem. 

Separation rings can be used as a predictable method to place Class II composite resins and obtain tight, well-contoured, interproximal restorations.
