Mixture of different sectional matrix rings to achieve contact separation

September 16, 2020

This was a back to back premolar Class II restorative case with the goal of closing open contacts.  The rubber dam clamp was placed on the first molar, obviating the placement of a Triodent V3 ring due to spring-off, so a Garrison Compositight was used in this position for the second molar and a Triodent V3 was placed for the first premolar.
