Adhesive Cementation (Variolink® II) | Conventional Cementation (ProTec CEM™)

General Considerations

  • IPS Eris™ 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™
