Indirect Cementation Solutions

When choosing the proper dental cement, it is critical to consider the material that is being used for the indirect restoration. Below is a summary of factors to consider for various substrates and restorative conditions.

Dental Substrate Considerations

METAL RESTORATIONS
Self-cure and dual-cure adhesive resin cements are ideal where little or no light can be transmitted through the restorative material.

• The cement you use should have a strong affinity to metal. If not, use a separate metal/zirconia primer (i.e. Z-Prime Plus).
• Self-adhesive cements are a good choice for retentive preparations.
• A self-adhesive resin cement containing the MDP monomer will have a higher affinity to metal (i.e. TheraCem).

ZIRCONIA OR ALUMINA
Dual-cure adhesive resin cements are recommended as only some light can transmitted through the restorative material.

• Dual-cure cements are ideal for crowns, bridges and inlays/onlays.
• Creating a hydrophobic, resin-loving, surface is imperative. This can be done by applying a primer such as Z-PRIME™ Plus or, by applying a dental adhesive that contains MDP (All-Bond Universal). Application of a primer  significantly enhances the bond strength between the resin cement and the dental substrate.
• If using an MDP containing selfadhesive resin cement (i.e. TheraCem), no primer is required.

*FELDSPATHIC CERAMIC LITHIUM DISILICATE/e.max
** A total-etch or, a universal adhesive system in the total-etch technique, along with a resin cement will yield the best results.

• HF etching & silanization of the ceramic surface is required.
• A total-etch or, a universal adhesive system in the total-etch technique, is recommended for treatment of the tooth surface.
• Light-Cure resin cements are ideal for dental veneers as they will prevent potential discoloration (shade shifting) over time and will provide maximum strength.
• A hema-free bonding resin (Porcelain Bonding Resin) is recommended for the internal surface of the veneer which will also aid in preventing discoloration over time.
• A dual-cure resin cement is recommended for crowns, bridges, inlays/onlays.

COMPOSITE
Dual-cure resin cements are recommended as light may be attenuated as it transmits through the restorative material.

• Any resin cement can be used as they all have a strong affinity to resin composite.
• A dental adhesive in the self-etch, selective-etch or total-etch technique can be used for a full coverage restoration.
• For inlays/onlays, a selective-etch or total-etch technique is recommended.

Restorative Considerations

MARYLAND BRIDGES
A total-etch or, a universal adhesive system in the total-etch technique, and a resin cement should be used as the retention of the bridge is highly dependent upon achieving a maximum bond.

• Dual-cure or self-cure resin cements are recommended as light transmission is limited.

SHORT CROWNS
A total-etch or, a universal adhesive system in the total-etch technique, and a resin cement should be used as the retention is highly dependent upon achieving a maximum bond between the tooth surface and restorative material.

• Priming the indirect restorative material is mandatory.

POSTS
Dual-cure or self-cure cements and/or dual-cure core build-up materials (i.e. Core-Flo DC/Core-Flo DC Lite) are recommended for metal posts as no light can be transmitted into the canal.

• Dual-cured resin cements are acceptable for light-transmitting fiber posts.
• Self-adhesive resin cements are a good option for both fiber and metal posts as it simplifies the bonding/cementation process by eliminating the need for bonding in the canal.*
• A self-adhesive resin cement containing the MDP monomer will have a higher affinity to metal (i.e TheraCem).
  *Post length must be a minimum of 8mm or bonding is recommended.

VENEERS
A total-etch or, a universal adhesive system in the total-etch technique, and a resin cement should be used as the retention of the veneer is highly dependent upon achieving a maximum bond to the enamel.

• A light-cured cement (i.e. Choice 2) will aid in preventing discoloration (shade shifting) over time.
• A hema-free bonding resin is recommended on the internal surface of the veneer.
• After HF etching, a pure silane should be used to prime the ceramic surface.
  It is not recommended to use a silanecontaining dental adhesive.
