Versatility: Excellent adhesion to different surfaces.
Dual curing: Light curing and chemical curing in areas where light does not fully reach.
Radiopacity: Possibility of radiographic diagnosis.
Definitive cementation of:
– Full porcelain crowns and bridges or fused to precious, semi-precious or non-precious metals
– Inlays, onlays, crowns and veneers made of porcelain or composite resin.
– Fiberglass, ceramic or metallic intraradicular posts.
Step by step
Isolate the tooth and use a retraction system when the margin is under the gum, to assure there will be no contamination of the preparation.
The application of phosphoric acid and adhesive into the tooth should follow the respective products’ protocols, according to the adhesion procedure.
1) Prosthetic pieces shall be treated according to their material: a- Metallic or metal-ceramic: we recommend sanding with abrasive particles to make it rough and increase anchoring for the piece. Also, the use of a primer for metal may be considered, to increase retention. b- Ceramic conditional or lab composite: we recommend acid etching of the internal surface using fluoride acid and subsequent application of silane, according to the manufacturer’s recommendations for the respective products.
After treating the piece, apply a thin layer of cement into it and bring it to position, ensuring proper flowing of the cement through the preparation margins.
Keep the piece on position and start cleaning the cement excess after approximately 3 to 5 minutes from the beginning of paste mixing. If the cement excess is removed shortly after positioning the pieces, the margins must be light cured to prevent the effect of the oxygen inhibited layer.
After allowing chemical curing for 3 to 5 minutes and removing cement excess, light cure each surface and the margins for 40 seconds or allow the chemical curing to continue up to 10 minutes from mixing the pastes.
Polish for finishing.
Instruct the patient to avoid exerting strength over the restoration until 15 minutes after fixing the piece.
Step by step
Cementation of Intraradicular Posts
With the operatory field free of humidity (under relative or absolute isolation), start preparing the canal in the length previously determined by the Whitepost (FGM) protocol
The application of phosphoric acid and adhesive into the canal should follow the respective products’ protocols, according to the adhesion procedure.
Apply the proper quantity of composite cement Allcem proportion 1:1 over a block for use with spatula. Mix both pastes with plastic spatula for 10 seconds. For twin body syringes, place the applying pointer and push the piston. Apply a thin layer of the mixture through the pin or apply the cement into the radicular canal with the help of proper instruments.
Position the pin into the radicular canal. Start the cleaning process about 3 to 5 minutes after inserting the cement. Proceed to light curing for 40 seconds at the occlusal surface to fix the pin into position.
Reconstruct the tooth’s coronal portion.
