Case Study Class II Restoration MODB #4 and #5 using Composi-Tight 3D and 3DXR - Robert Rosenfeld, D
Robert Rosenfeld, DDS
The 3D rings do a beautiful job of preventing flash by pressing the sectional matrix band against the tooth to be restored. With the prior ring generation, there were some teeth whose anatomical shape resulted in pop-off. With the addition of the new 3DXR ring, that almost never happens. It has become the go-to ring, especially for more challenging situations.
