Calibra is a two-paste, dual-cured cement that is used in conjunction with Prime & Bond NT Dual Cure dentin bonding agent for luting indirect restorations. The Calibra Complete System is packaged in two plastic "tackle-box type" cases. The first contains the cement and includes five syringes of base paste in shades Transparent, Light, Medium, Dark, and Opaque as well as one syringe each of two viscosities (Regular, High) of unpigmented catalyst paste. The Prime & Bond NT bonding agent and phosphoric acid etchant are included in the same case. The second plastic case contains five syringes of the corresponding shades of try-in pastes and a syringe of silane solution. Calibra is recommended for the luting of all-metal, all-ceramic, all-resin, and porcelain-fused-to-metal restorations as well as posts and resin-bonded fixed partial dentures. It is contraindicated for use as a liner/base, core build-up material, or restorative material. In addition to detailed written instructions, a graphics-containing instruction card booklet is also provided.
Clinical evaluators found Calibra Adhesive Resin Cement easy to mix with a thin film thickness. The working time was long enough that users did not have to rush during mixing and placement, and the relatively short setting time minimized post-cementation chair time. It was very easy to clean excess cement from margins. Patients did not report any post-treatment sensitivity. Esthetically, the cement performed well, in part because it had five shades from which to choose and included try-in pastes. The kit includes silane solution and a bonding agent necessary for some of the procedures listed in the instructions. Evaluators appreciated the excellent illustrated instruction booklet. Expiration dates and lot numbers were provided for all items in the kit and a Material Safety Data Sheet (MSDS) was included in the kit.
Calibra is more expensive than some other popular resin cements. One evaluator felt that some of the shades were too similar in appearance. The kit does not include hydrofluoric acid for porcelain/ceramic etching.
