Adhesive Cementation (Variolink® II)

|

Conventional Cementation (ProTec CEM™)

General Considerations

• IPS Empress 2 can be either bonded using established adhesive techniques, or cemented with conventional cements.
• Bonding with Variolink® II is the method of choice.
• However, if isolation is a problem or a deep marginal area prevents using adhesive techniques, Ivoclar recommends using ProTec CEM™

ADHESIVE TECHNIQUE (Variolink® II)

1. Bridges and full coverage crowns fabricated using IPS Empress 2 material.
2. Ideal resistance and retention form.
