ContacEZ Diamond Dental Strip Makes Crown Seating Simple & Easy.
ContacEZ Diamond Dental Strip is an innovative, new precision dental device designed to achieve proper proximal contact and complete marginal seating of crowns and inlay/onlays simply and easily.
How to use ContacEZ Diamond Dental Strip, the ideal proximal contact adjuster
It is extremely important to tell your dental lab to retain the natural contour and space between the adjacent teeth. The models should not be scraped. If scraping is desired, it should not be exceed 0.10mm in thickness.
Directions for proximal contact adjustment for crown seating
1. Place the crown on the prepared tooth and press it down. Check the marginal fit with an explorer. If there is a marginal opening due to overly tight contacts, determine if the mesial or distal margins are more open. The side where the margin of the crown is close to the prepared tooth surface is the side with the heavier proximal contact. If the crown is far off from the preparation, a rotary instrument is recommended for gross adjustment before using ContacEZ Diamond Dental Strip.
2. Lift the crown from the prepared abutment tooth and insert a ContacEZ Diamond Dental Strip into the interproximal space that has the heavier contact. Ensure the abrasive surface is facing the crown.
3. Place the crown back on the prepared tooth and let the crown rest on the abutment. Do not press the crown at this stage. Pass the ContacEZ Diamond Dental Strip buccolingually five to six times. The orientation of the diamond particles on the metal strip may initially limit movement of the strip to one direction only.
4. Remove the ContacEZ Diamond Dental Strip from the interproximal space and put it back into the other interproximal space of the crown while the crown is lifted slightly.
5. Pass the ContacEZ Diamond Dental Strip buccolingually approximately 6 times.
6. Remove the ContacEZ Diamond Dental Strip from the interproximal space and check which interproxomal space is more stressed against the ContacEZ Diamond Dental Strip.
7. The interproximal space with the heavier resistance to the ContacEZ Diamond Dental Strip is the side heavier contact may require additional passing of the ContacEZ Diamond Dental Strip.
8. Repeat steps 6 and 7 until the ContacEZ Diamond Dental Strip passes through the interproximal space with light resistance.
9. After cementation of the crown, remove excess cement and confirm interproximal relief* by passing the ContacEZ Diamond Dental Strip through the interproximal space. When interproximal relief is achieved, the ContacEZ Diamond Dental Strip passes through the interproximal space with light resistance and dental floss passes through with firm resistance.
10. Evaluate the occlusion and adjust if necessary.
ContacEZ Diamond Dental Strip is also useful for the proximal contouring of composite fillings.
