Tetric N-Bond Universal
Universal and technique tolerant
Schaan, Liechtenstein – 2 March 2015
A new single-component, light-cured universal adhesive for direct and indirect restorations is ready to launch.
Tetric N-Bond Universal adhesive is suitable for the total-etch technique, as self-etch adhesive and for selective-enamel-etch procedures. It features high bonding capabilities to both dry and moist dentin substrates.
The universally applicable adhesive establishes a strong bond to restorative and luting composites and is suitable for direct and indirect bonding procedures. As the adhesive is applied in a low film thickness, it does not impair the accuracy of fit of indirect restorations. No dual-cure activator is required for the cementation of indirect restorations.
Compatible with all etching techniques
Tetric N-Bond Universal combines hydrophilic and hydrophobic properties. It is tolerant to moisture, penetrates open dentin tubules effectively and seals them reliably. Since Tetric N-Bond Universal is moderately acidic, it is compatible with any etching technique (self-etch, selective-enamel-etch or total-etch) and ensures an optimum bond between the tooth structure and the dental restorative.
The new adhesive is technique tolerant and forgiving. It forms a stable and homogeneous layer that is not sensitive to any application technique. Consistently high bond strengths on enamel and dentin are achieved irrespective of the etching protocol employed, using only a single layer of adhesive. The acetone-free, hydrophilic solvent contained in Tetric N-Bond Universal ensures optimum wetting of the dentin and enamel, reducing the risk for microleakage and postoperative sensitivity. Given the adhesive’s hydrophilic components, “wet-bonding” is no longer an absolute necessity. A high bond strength to the dentin can be achieved even if the dentin is etched with phosphoric acid and has become excessively dry.
Universal delivery form
The simple “Click” activation of the VivaPen delivery form allows the exact amount of adhesive material to be dispensed for each procedure. Dispensing of adhesive material into a dish before the application is not required. Thus, residual material waste is considerably reduced. The VivaPen contains 2 ml of adhesive, which is sufficient for approx. 190 single-tooth applications. Compared to conventional bottle delivery forms, this amounts to almost three times more applications per millilitre.* VivaPen is also available in a conventional bottle delivery form.
