Griptab by Triodent
Simplifies, de-stresses handling of esthetic indirect restorations.
Working with indirect esthetic restorations brings with it a constant challenge—confidently handling such fragile and often slippery objects during preparation for bonding, loading with bonding material, and during placement, when accuracy is critical. The Griptab by Triodent has been designed as an extremely simple yet comprehensive system for controlling all indirect restorations during pre-bonding and cementation procedures. It comes with plastic tabs of three different shapes and sizes that can be bonded to all porcelain and metal restorations with a light-cured adhesive.
The Griptab is normally used with a pair of pin-tweezers that provide a secure grip while at the same time allowing free rotation through more than 180° in one plane (Figure 1 and Figure 2). A small hemostat will work, but not as effectively. Griptab is the first such product to achieve the universal goals of reliable adhesion, ease of placement, and the ability to passively release the restoration and pick it up again multiple times during the same procedure, whether crowns, veneers, inlays, or onlays. Reliable, accurate placement of veneers is vital. The removal of adhesive stick systems can lead to accidental displacement of a veneer, causing unnoticed air entrapment and failure at either a bonding or esthetic level. The Griptab provides complete, secure control of the restoration. Modifying the internal tints and colors in bonding resins for veneers requires a firm, stable grip on the veneer while areas of it are loaded with different-colored resins as needed for optimal esthetic matching. Griptab improves the accuracy of resin placement and consequently improves the esthetic outcome. Managing small inlays and onlays during hydrofluoric etching and silanation is problematic. The Griptab system ensures complete control not only during preparation for bonding but also during the placement of the resin cements, transfer from the assistant to the dentist, and final placement of the restoration in the cavity. The dental assistant can carry out the majority of the steps in the Griptab process and there is also the option for laboratories to provide restorations to the dentist with the Griptab already attached. Among the advantages of Griptab are that the occlusion can be checked on crowns and onlays while the Griptab is still attached. This cannot be done with inlays, but neither is this possible with any placement system available. Much work has gone into the Griptab adhesive. It was essential that the adhesive be completely reliable but at the same time not present a problem on removal of the Griptab. The adhesive that has been developed is flexible and moisture-resistant. As long as the restoration surface is free of contaminants at the start of the procedure, the adhesive will not fail during hydrofluoric etching, ultrasonic cleaning or silanating, and, most importantly, will leave no residue when the Griptab is removed at the end of the procedure. The adhesive is light-cured with a conventional dental curing light and changes from pink to gold when polymerized. Once the procedure is complete, the Griptab may be eased away from the restoration using a flat-bladed metal instrument (Figure 3). Before it is completely detached, it can be picked up with the pin-tweezers and removed.
