In the patient’s mouth, insert the ContacEZ Black Diamond Strip into the distal and mesial interproximal spaces with the abrasive side facing the crown to determine which side has heavy contact. The side with more pressure is the side with heavier contact.
Adjust proximal contact by moving the strip buccolingually, without vertical force, about 6 times on the side with heavier contact. Repeat this motion until equal pressure is felt on both sides. Proximal contact adjustment is complete, and the crown is ready for definitive cementation.
