Allcem Dual Cure Resin Cement (FGM)

Description

Benefits

Versatility:
Excellent adhesion to different surfaces.

Dual curing:
Light curing and chemical curing for areas where light does not fully reach.

Radiopacity:
Possibility of radiographic diagnosis.

Recommendations

Porcelain fused-to-metal crowns and bridges;

Metal crowns, bridges, inlays and onlays (high noble, noble, and base metals);

Crowns and bridges with minimal tooth structure;

Maryland bridges (resin bonded bridges);

All ceramic/porcelain and pre-cured composite crowns, bridges, inlays and onlays;

Endodontic posts; Note: For cementation of laboratory-fabricated veneers, use Allcem Veneer APS.

Step by step

Step 1
The Full Porcelain  or metal-ceramic piece must be previously submitted to an aluminum oxide jet treatment by the laboratory in order to generate superficial microporosities and in the case of composite pieces, the preparation can also be done with fine burs, prepare the ceramic piece (if its an etchable ceramic ) applying fluoridric  acid (e.g. condac porcelana, FGM ) in its internal surface, according to the manufacturer’s indications. Rinse the piece abundantly with water to remove all the acid and dry it well.

Step 2
silanization of the piece: apply silane (Prosil, FGM ), Which is an uncolored solution, to the piece with the aid of a disposable microapplicator and wait for 1 minute. Dry the surface jets of compressed air.

Step 3
Select the appropriate color of dual-curing resin cement for cementation of the piece. Place the appropriate amount of Allcem on the spatulation plate and mix the pastes during 10 seconds with spatula or use the self-mixing tip which should be discarded after its use. Allcem is presented in a double-body syringe (base + catalyst pastes) and disposable self mixing applicator tips, which make the mixture of the pastes in the adequate proportion without creating bubbles. Allcem is also presented in isolated syringes of base paste and catalyst paste.

Step 4
Apply a fine layer of cement inside the piece or in the cavity covering the whole surface.

Step 5
Carefully position the piece on the tooth allowing the cement  to slowly flow from all the margins.

Step 6
Keep the piece in position and start cleaning the excess cement approximately 2 minutes after beginning to mix the pastes. In case the excess cement is removed right after the positioning of the piece, the margins should be light cured to impede the effect of the layer inhibited by oxygen. In case of minimally retentive restorations, position the piece and keep it still during the cleaning process of the excess cement.

Step 7

After removing the excess of cement, light cure each surface and margins for 40 seconds or allow chemical curing to occur for 10 minutes after mixing the pastes.

Step 8

Proceed to finishing and Polishing.

Step 9

Instruct the patient not to bite on the restored teeth at least  for 15 minutes after cementation.

Note
After light curing of the restoration and its margins, remove the excess of cement with a scalpel. The use of rotatory instruments should be avoided before total curing of the cement which may occur in about 10 minutes after mixing the pastes, according to the local temperature.
