IPS e.max lithium disilicate is a silaca-based ceramic, so HF etching followed by silane treatment is the recommended. The bonding/cementing procedure follows:
- Try in e.max
- Etch the internal surface of e.max with 4-5% HF etchant for 20-25 sec. Rinse with water and dry.
- Treat the internal surface with silane primer, 1 coat, 1 min, air dry.(Note: only pure silane primer is recommended, such as Bisco Porcelain Primer or BisSilane)
- Apply a bonding technique of preference. BISCO recommends Selective Etch
- Use dental adhesive such as All Bond Universal on the prep.
- Use dual-cure resin cement such as Duo-Link Universal.
