G-ænial Bond Technical Manual
Self-etch technique: Class V
The study followed the test set-up as defined page 28:
• Standardised Class V preparations were made in extracted incisors (8 per group).
• The adhesive system GBA 400 (commercially available as G-ænial Bond) was applied in combination with GC Gradia Direct
Posterior according to the manufacturer’s instructions.

adapted excerpt from Dr u. Blunck, charité universitätsmedizin Berlin, Germany, 2008
Sem evaluation of the samples after thermocycling demonstrated excellent marginal adaptation of
G-ænial Bond to both enamel and dentine using the self-etch technique (Figure 25), with median
values of 100 % “continuous margin” and mean values of about 97% to 99%.
Etch-and-rinse technique: Class V
The study followed the test set-up as defined page 28:
• Standardised Class V preparations were made in extracted incisors (8 per group).
• The Class V preparations were treated with G-ænial Bond after phosphoric acid etching the entire preparation for 10 s, then
restored with either GC Gradia Direct Posterior, GC G-ænial Posterior, GC Kalore or Filtek Z250 (3M ESPE) using an
incremental technique.

V restorations, before and after thermocycling (tc) for G-ænial Bond along with the etch-rinse-technique, restored with one of
four composite resins. Source: adapted excerpt from Dr u. Blunck, charité universitätsmedizin Berlin, Germany, 2010
Sem evaluation of the marginal adaptation after thermocycling demonstrated a “continuous
margin” in both dentine and enamel, with median and mean values of about 99% to 100 % margin
quality. this result was achieved for all restorations applied with G-ænial Bond after phosphoric
acid etching, irrespective of the composite used for the restoration.
