Should you cement or should you bond?
The answer is not clear-cut, as it depends on the clinical situation. Cementation with a glass ionomer-based resin cement – like FujiCEM Evolve – or with a self-adhesive composite resin cement – like G-CEM ONE – each has its own merit. Read further to investigate the important criteria through case studies – after all, the choice between cementation and bonding can make all the difference!
Choose a resin modified glass ionomer, like FujiCEM Evolve
In this case, there is adequate retention: more than 4 mm near-parallel walls.
Subgingival margins are present. Absolute isolation of the margins from moisture cannot be guaranteed in this case without corrections to the surrounding tissues.
The dental history shows a high caries risk.
The restoration is not highly translucent and the margins are not visible when the patient is smiling. Aesthetic requirements are not predominant.
When there is sufficient retention, there is no need for bonding with a resin cement. Yet FujiCEM Evolve demonstrates high bond strength, in particular to zirconia.
Like all glass ionomers, FujiCEM Evolve is moisture tolerant.
FujiCEM Evolve protects the tooth from caries and does not induce post-operative sensitivity.
A Universal shade can be used here without compromising the appearance of the patient’s smile.
Choose a self-adhesive resin cement, like G-CEM ONE
When the walls are too low or convergent (>20°), adequate retention is lacking and adhesive bonding becomes mandatory.
The preparation can be properly isolated with rubber dam so bonding can occur in the absence of contaminants.
This patient does not have increased caries risk.
Aesthetics are important to this patient and the restorations are visible when smiling. An appropriate shade should be selected that does not interfere with the shade of the restoration and will not be noticed in the marginal zone.
G-CEM ONE contains MDP, which chemically bonds to Zirconia, without needing a separate primer. It features excellent self-curing ability, enabling perfect setting even under opaque restorations.
G-CEM ONE is a universal resin cement which requires an aboslute isolation. However, used with G-CEM ONE Adhesive Enhancing Primer, the bond strength can be ensured even in moist environment.
G-CEM ONE provides a tight seal between the tooth and the restoration. Etching is not required, reducing the risk to post-operative sensitivity.
With many shades to choose from, the shade and translucency ensuring the best aesthetic outcome can be selected.
