G-ænial Bond Technical Manual
Conclusion of the Class V study
Within the limitations of this study, the adaptation of G-ænial Bond in class V preparations has
proven to be very effective using either the self-etch or the etch-and-rinse technique, independent
of the composite used. It is therefore expected that the long-term marginal adaptation of
G-ænial Bond restorations will also be very effective under similar clinical conditions.
7.4.2 marginal analysis in class i restorations after thermocycling and mechanical
loading
Tests performed by Dr Uwe Blunck- Charité Universitätsmedizin Berlin
the purpose of this study was to examine the marginal integrity of composite resin restorations in
class i preparations with margins in enamel treated using either a self-etch or an etch-and-rinse
technique. testing was conducted before and after thermocycling procedures and after mechanical
loading.
Self-etch technique, class I
The study followed the test set-up as defined page 28:
• Eight Class I preparations per group were prepared and filled in extracted human molars
• Various adhesives were applied and the preparations were filled with Filtek Z250 (3M ESPE) using an incremental technique.

and mechanical loading for GBa 400 (G-ænial Bond) in comparison to contemporary adhesive systems (all in combination with
Filtek Z250). G-ænial Bond (GBa 400) was applied using the self-etch technique. Source: adapted excerpt from Dr u. Blunck,

For the self-etching technique (Figure 27), comparison with the results of contemporary adhesive
systems, including the standard references for in-vitro tests (etch-and-rinse system OptiBond Fl
and two-step self-etching adhesive clearfil Se Bond), demonstrated the effectiveness of the GBa
400 adhesive (commercially available as G-ænial Bond). there were no statistically significant
differences in the results for G-ænial Bond compared to the etch-and-rinse adhesive system or the
two-step self-etching adhesive.
