Tetric N-Flow is a light-curing, radiopaque flowable nano-hybrid composite based on nano-optimized technology. Tetric N-Flow is based on 10 years of tradition and the clinical performance of Tetric Flow. Because of the material’s outstanding wetting ability even in areas that are hard to reach, it is particularly suitable for use as a cavity liner and for small cavities of any kind. At the same time, the material offers outstanding stability and is thus ideal for Class V restorations.
Tetric N-Flow is the ideal complement to Tetric N-Ceram for an esthetic restoration.
Tetric N-Flow is available in 10 shades – 6 enamel, 1 dentin, 1 incisal and 2 bleach shades. It is supplied in both syringes and Cavifils.
- As initial layer under class I and II restorations
- Anterior restorations (Classes III, IV)
- Class V restorations (cervical caries, root erosion, wedge-shaped defects)
- Small restorations of all types
- Extended fissure sealing
- Splinting of mobile teeth
- Blocking out of undercuts
- Adhesive cementation of translucent ceramic and composite restorations
- Dimethacrylate and TEGDMA (22 wt%).
- The fillers include barium glass, ytterbium trifluoride, silicon dioxide and mixed oxide (76 wt% or 60 vol%).
- Additives, initiators, stabilizers, and pigments are additional contents (2 wt%).
Storage temperature 2–28 °C (36–82 °F)
- The particle size of the inorganic fillers is between 0.04 and 7 µm.
- The mean particle size is 850 nm.
- If a dry working ﬁeld cannot be established or the stipulated application technique cannot be applied.
- If a patient is known to be allergic to any of the ingredients.
- Direct pulp capping with Te-Econom Bond/Flow/Plus
SIDE- EFFECTS –
- In rare cases, ingredients may lead to sensitization.
- The products should not be used in such cases.
- To avoid possible irritation of the pulp, areas close to the pulp should be protected with a suitable pulp/dentin protector
Direction to Use
Application of Tetric N-Flow
- Tetric N-Flow Bulk Fill can be applied in increments of up to 4 mm thickness.
- Tetric N-Flow Bulk Fill must be covered with a layer of methacrylate based universal or posterior composite (e.g. Tetric N-Ceram/Tetric N-Ceram Bulk Fill/IPS Empress Direct).
- Proximal contacts must be established by means of a matrix system. The filling material does not exert any pressure on the matrix band. The matrix band can be shaped with a suitable hand instrument (e.g. a balltype condenser) before and/or during light-curing.
- Complete polymerization requires a sufficiently long exposure time. 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 lingual/palatal aspect after removing the matrix, if no Bluephase N polymerization light is used or the light probe cannot be ideally positioned, e.g. distant to composite or diverging scattering angle.
