Ivoclar Vivadent Tetric N – Ceram Bulk Fill Universal Shade IVA

Features

Description

Tetric N-Ceram Bulk Fill is the efficient four-millimetres posterior composite of the nano-optimized Tetric N-Collection.

Tetric N-Ceram Bulk Fill enables posterior teeth to be restored with only one layer measuring up to four-millimetres in thickness, which considerably heightens efficiency.The patented light activator Ivocerin is responsible for ensuring the complete cure of the filling. Compared with convential light initiators, the Ivocerin polymerisation booster is much more reactive. Therefore, polymerization is initiated even in very deep cavities and the material is fully cured.

A specially conditioned shrinkage stress reliever keeps shrinkage and shrinkage stress during polymerization to a minimum. Tetric N-Ceram Bulk Fill is available in three universal shades: IVA, IVB and IVW (universal A shade, universal B shade and for deciduous teeth or light-coloured permanent dentition).

Indications

• Restoration of deciduous teeth
• Restorations in the posterior region (Class I and II)
• Class V restorations (cervical caries, root erosion, wedge-shaped defects)
• Preventive resin restorations in molars and premolars

Key Specifications

Composition

The monomer matrix is composed of dimethacrylates (19?21% weight). The total content of inorganic fillers is 75?77% weight or 53-55% volume. The fillers consist of barium glass, prepolymer, ytterbium trifluoride and mixed oxide. Additives, catalysts, stabilizers and pigments are additional contents (< 1.0% weight). The particle size of the inorganic fillers is between 0.04 and 3 µm. The mean particle size is 0.6 µm.

Packaging

• 1 x 3.5 gm Syringe

Direction to Use

• In order to achieve optimum results, Tetric N-Ceram Bulk Fill should be applied in increments of max. 4 mm and adapted to the cavity walls with a suitable instrument (e.g. OptraSculpt). Use a special contact point instrument (e.g. the bifurcated OptraContact) for large cavities where contacts are difficult to create.
• Sufficient exposure to the curing light prevents incomplete polymerization. For the recommendations regarding exposure time and light intensity see Table.

• When using a metal matrix, additionally polymerize the composite material from the buccal or the lingual/palatal aspect after removing the matrix, if no Bluephase polymerization light is used or the light probe cannot be ideally positioned, e.g. distant to composite or diverging scattering angle.
• In many cases, a flowable composite is used today as an initial layer to create an even cavity floor and to facilitate the adaptation of the subsequently used restorative material. A flowable composite (e.g. Tetric NFlow) can be applied in a thin initial layer. This optional layer must be cured separately
