Excellent Crown Seating Simple & Easy

Black Diamond Dental Strip: This fine diamond strip is essential to adjust the proximal contact of indirect restorations like lab fabricated or CAD/CAM milled crowns, onlays, or inlays, and restore proper proximal contacts of indirect restorations.
White Serrated Strip: This serrated strip is popularly used to cut and clean out cement that is trapped in the interproximal space.
Gray Final Polishing Strip: This ultra fine diamond strip is useful to polish the proximal contact surface to restore a natural finish and confirm Interproximal Relief after definitive cementation.
LAB Stone Strip (Clear): This medium diamond strip from the ContacEZ LAB Strip System is useful to adjust proximal contacts of crowns on the working stone model when the crown does not seat properly on the abutment in the patient's mouth. This usually occurs because the adjacent teeth on the working model are scraped too much at the dental lab and the crown is made too large.
Crown Seating Made Easy!
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.
The crown is now ready for definitive cementation. After the crown is cemented, if there is excess cement trapped in interproximal spaces, use the White Serrated Strip to cut and clean out the trapped cement.
Using the Gray Final Polishing Strip, polish the adjusted proximal surfaces of the crown to restore a natural finish in one step. This strip also confirms Interproximal Relief* after definitive cementation.
The crown now has complete marginal seating. Dental floss will pass through the interproximal contacts with heavy resistance, snapping in and snapping out. ContacEZ’s innovative crown seating method allows you to seat crowns simply and easily, with minimum time and effort.
IF THE CROWN DOES NOT FIT...
Check the clearance between the inner surface of the crown and the surface of the prepped abutment with an explorer. The side with less clearance is the side with heavier contact.
Place the crown onto the working stone model and pass the LAB Stone Strip (Clear) back and forth a few times with the abrasive side facing the crown in order to lighten the contact. Squeeze the model towards the crown to increase abrasion. Place the crown back into the patient’s mouth, and use the Black Diamond Strip to complete ideal proximal contact adjustment.
