Episode notes
When To Use Monolithic Zirconia
- Use monolithic zirconia for most posterior crowns to simplify cementation and improve strength.
- Layer ceramic on anterior incisal edges when you need added translucency and aesthetics.
E.max Can Be Cemented If Thick Enough
- Lithium disilicate (e.max) shines when bonded for strength but can be conventionally cemented at greater thickness.
- Adequate thickness lets you choose simpler luting methods when isolation is challenging.
Match Cement To Retention Needs
- Choose cement based on retention: use self-adhesive or RMGI for well-retained zirconia, resin cements for low-retention cases.
- Bond non-retentive restorations with Panavia V5 or similar resin adhesives for reliable retention.
