Description

Prime & Bond NT is a self-priming, light-cured bonding agent that contains nanofillers of amorphous silicone dioxide, which differentiates this product from Prime & Bond 2.1. In addition to the nanofillers, Prime & Bond NT is primarily composed of di- and tri-methacrylate resins, PENTA (dipentaerythritol penta acrylate monophosphate), and contains an acetone solvent. It combines both the primer and adhesive in a single bottle and requires one application followed by a 10-second light cure. Prime & Bond NT is designed to bond composite materials and compomers to enamel and dentin. It is also indicated for the bonding of veneers, composites and ceramics, as well as an adhesive cavity varnish for amalgam. The introductory kit contains one, 4.5-ml bottle of adhesive, 40 disposable brush tips, an applicator brush handle, a re-usable well, an instruction booklet, and a laminated instruction card. The introductory kit does not contain an etchant; however, the economy kit contains three, 4.5-ml bottles of adhesive, one syringe of etching gel and accessories. Twenty-two consultants evaluated Prime & Bond NT in over 450 clinical cases. This product received a 91% clinical rating.

Product Features

Prime & Bond NT was highly rated for its instructions and ease of coating the preparation. Consultants found the system easy to use, and they appreciated the single-bottle, one-step system. The squeezable bottle and good flow of the adhesive contributed to the ease of dispensing. In addition, no bonding problems were reported over the three-month evaluation period. The majority of consultants found Prime & Bond NT to be equivalent to or better than their current adhesive and indicated that they would switch to it. Eighty-two percent of consultants would purchase Prime & Bond NT, and 94% would recommend it.

Clinical Tips

Do not dispense until ready to apply to avoid evaporation of solvent.

Eugenol-containing materials should not be used with Prime & Bond NT, because they may interfere with the polymerization of polymeric components.
