Allcem Core is a dual-curing resin cement indicated for core build-up and adhesive cementation of intraradicular posts and prosthetic crowns
More info


Due to its balanced viscosity, Allcem Core provides excellent flow properties for cementation and allows core build-ups to be easily sculpted into the desired format, enabling perfect adaptation of future prosthetic crowns. By combining practicality with mechanical resistance, Allcem Core is simple to use and a reliable product that ensures the rehabilitation of severe loss of tooth structure. Find out more about this resin cement that simplifies the rehabilitation of teeth with large structural loss and which can be used as a 3 in 1 material.

Characteristics and Advantages

• Practicality and versatility: one product suitable for performing 03 procedures effectively, quickly and securely: intraradicular post cementation, core build-up and cementation of prosthetic crowns.
• Aesthetics: available in the colors A1, A2, A3 or Opaque Pearl to meet different aesthetic demands.
• Increases the stability and strength of the “set”, as when carrying out the core build-up with the same material and in the same operative time, it forms a “single body” of the intraradicular retainer and the core build-up.
• Adequate viscosity: balanced flow allows the construction of the core and cementation of posts and crowns with ease.
• Radiopaque: enables radiographic monitoring and inspection of eventual subgingival excesses.
• Dual curing: chemical curing in environments where light does not reach and light curing to facilitate the core build-up work.
• High resistance to bending and compression.
• Applicator tips: the product is applied evenly inside the canal, avoiding manual mixing and insertion with a Lentulo spiral.


• Cementation of intraradicular carbon, quartz, metal and fiberglass posts (e.g. Whitepost – FGM).
• Production of the core build-up (vital or non-vital teeth).
• Cementation of crowns (ceramic, laboratory resin, metal or metal-ceramic).
• For cementation of veneers, we suggest the use of resin cements (e.g. Allcem Veneer – FGM).

Step by Step

Step 1

With the operative field free of moisture (under relative or absolute isolation), begin preparing the canal at the previously determined length (Whitepost protocol, FGM).
Figs. 1a and 1b: Preparation with a Whitepost drill, conferring a tapered housing for the post.

Step 2

The canal should receive acid etching (e.g. Condac 37, FGM) and adhesive (e.g. Ambar, FGM), in accordance with the adhesive procedure.
Figs. 2a and 2b: Acid etching and application of adhesive with subsequent removal of excesses and light curing.

Step 3

Use the self-mixing syringe tip to insert cement into the canal and then place the post. Excess cement can be used to support the core build-up, and more cement used around the post. The procedure takes approximately one hour and thirty minutes and the curing time takes forty seconds per increment.

Figs. 3a to 3c: The system provides versatility for cementing the post and constructing the core build-up in the same operative step. The coronal portion should be light cured to speed up the work for forming the core.

Step 4

Once the posts are cemented and cores are built-up wait six to seven minutes (intraradicular) for proper chemical curing and then sculpt the material if required.
Figs. 4a and 4b: Posts with coronal portion incremented and in its primary form. For refining the form, conventional preparation drills are an efficient solution.

Step 5

Cementation of the definitive crowns can also be conducted using Allcem Core using the same adhesive protocol (acid etching and application of adhesive).

Can I replace traditional Allcem with Allcem Core?

Yes, as all the indications of the traditional Allcem may also be performed using Allcem Core with excellent results.

Can Allcem Core cement self-cure inside the canal where light-curing procedure cannot be performed?

Yes, as it is a dual-cure cement. Chemical curing occurs in the absence of light and takes 6 to 7 minutes once the product is mixed.

Can Allcem Core replace traditional composite resin for core build-up procedures?

Yes, because its excellent physical and mechanical properties enable proper core build-up and therefore support future prosthetic restoration.

Information for the Professional

Precautions and Contraindications

• The product may cause some level of irritation if in contact with the dental pulp and/or very close to it. If there is pulp exposure during dental preparation or the cavity is very deep, protect the pulp wall with lining material cavity or cavity base.
• Allcem Core contains curing monomers that can cause skin sensitization (allergic contact dermatitis) in susceptible individuals. After contact, wash the area immediately with soap and water.
• Allcem Core contains methacrylates that could be irritant to the eyes. In case of contact, rinse immediately with plenty of water and seek medical attention.
• Do not use materials containing eugenol as a base in order to avoid insufficient curing on the surface.
• To accelerate the curing process, light cure Allcem Core for at least 40s with Halogen or LED equipment with power density equal or superior to 450mW/cm² and emission of spectrum of blue light (400-500 nm). Wear protective eyewear when using a light-curing unit.
• It is recommended to set the dental light reflector so that it is not aimed directly onto the tooth during cementation as the lamp may lead to a premature curing of the cement.
•Allcem Core is not compatible with one-step self-etch adhesives when not light cured.
• The self-mixing tips must be discarded after use.
• Be sure to close the lid of the packaging after use.
