Testing edge seal by observing dye penetration
The tightness of the edge seal after alternating mechanical and thermal load is outstanding. 92.5 % of all samples showed no dye penetration; 7.5 % showed only minimal discoloration on the edges. In other words, 100 % of the samples exhibited no or only minimal edge discoloration – a highly positive outcome. The adhesive retention also proved to be stress-resistant. No retention losses were seen.

Optimised abrasion resistance
The abrasion resistance of Synergy D6 is comparable to that of natural enamel and protects the opposing cusps.
One Coat Bond
Strong bonding values
One Coat Bond only requires a single application step for perfect adhesion. COMPONEER in combination with One Coat Bond demonstrates excellent adhesion, on composite, enamel and dentin. This ensures reliable and long-lasting adhesion of the restoration. The adhesive strength of COMPONEER is considerably greater than that for ceramic veneers due to the special micro-retentive surface.
