CASE REPORT - A Cerec Inlay Seating Method Using the ContacEZ Diamond Dental Strip

The ContacEZ Diamond Dental Strip confirms interproximal relief and leaves the inlay on tooth #18 smooth and naturally contoured.

ContacEZ Diamond Dental Strip is an innovative new precision dental device designed to use prior to final cementation to achieve proper proximal contact adjustment of direct or indirect restorations. Use of ContacEZ Diamond Dental Strip restores Interproximal Relief by eliminating excessive pressure between the restoration and the adjacent teeth, and complete marginal seating is achieved simply and easily!

 Fig. 5) The inlay body was placed in the preparation. It was found that the inlay was incompletely seated due to excessively heavy proximal contact. Note the opening of the gingival margin in the mesial proximal embrasure of tooth #18.

 Fig. 8) The ContacEZ Diamond Dental Strip was passed through buccolinually 23 times while the inlay body was gently pressed, until light resistance was achieved. At first, the strip moved in one direction only due to excessively heavy proximal contact. Therefore, the ContacEZ Diamond Dental Strip was passed approximately the first 10 times in one direction only by making a circular motion and was gradually able to pass in both directions buccolingualy.
