VITAVM®7

Fine-structure ceramic for all-ceramic framework materials in the in the CTE range of 7.2-7.8

VITA VM 7 was developed as a special fine-structure feldspar veneering ceramic for all-ceramic substructure materials in the CTE range of 7.2–7.8 (of Al2O3).

Like all VITA VM materials, VITA VM 7 is distinguished by its light refraction and reflection properties resembling those of natural tooth enamel. The use of additional fluorescent and opalescent porcelains permits outstandingly individual, high quality results.

  • Easy to use due to optimal consistency and modeling properties
  • Superb grinding and polishing results, especially in situ
  • Homogenous, dense surfaces
  • Proven to closely resemble tooth enamel
  • Outstanding firing stability even after several firing processes
  • a full range of additional materials for individualization
  • Compatible with VITA AKZENT Plus and VITA INTERNO stains

A study carried out by Giordano of the Goldman School of Dental Medicine, University of Boston, investigated the abrasion behavior of various ceramic materials in comparison to that of natural tooth enamel. VITA VM 7 was found to be the best material, as its fine structure results in abrasion behavior almost identical to that of natural tooth enamel.

Tearing
  • To support the structure, model in reduced tooth size in order to achieve a uniform layer thickness of the ceramic. Ensure cuspal support of the posterior area. Ensure U-shaped modellation of the interdental spaces.
  • When mixing all ceramic materials ensure that no bubbles are formed. Make sure that the liquid is added to the powder from the side and stir the mixture thoroughly using a glass or agate spatula. The use of metal spatulas can lead to metal abrasion and discoloration of the ceramic.
  • Keep workplace clean; dust and dirty brush water may cause problems (such as formation of bubbles).
  • Do not apply insulating (separating) liquids too thickly.
  • When firing bridges, always separate down to the substructure. Shrinkage of the ceramic always occurs only in the thickest area. Therefore a uniform layer thickness is recommended. Do not use any dry or saw-toothed instruments. The use of these instruments can cause the ceramic to become detached and separated from the surface.
  • Ensure correct firing parameters and firing temperature. For the muffle test, use a mirror to look into the firing chamber and check whether the muffle is firing properly.
  • If a rubber polisher is used before the final finishing, the surface must not be wetted with liquid again. It must first be cleaned. It is not sufficient to clean it using a steam cleaner or with water. Silicone residue at the surface must be removed mechanically using a goat-hair brush.
  • Insulation material residue must not be left on the ceramic surface. Contact with the freshly insulated antagonists (opposing jaw) can lead to problems.
  • When filling the interdental spaces during bridge correction, do not vibrate the material until dry, otherwise the material will not bond. Interdental spaces should be wetted with an oily liquid (e.g. VITA Interno) before filling.
Bubbles
  • Use only diamond instruments and a water-cooled turbine
    for processing the substructure. Do not apply too much
    pressure and use the indicated speed (observe manufacturer's
    instructions). Avoid heat development at the
    surface during finishing. Do not use finishing instruments
    unless necessary. Thermal (heat) treat substructure after
    grinding.
  • When mixing all ceramic materials ensure that no bubbles
    are formed. Make sure that the liquid is added to the
    powder from the side and stir the mixture thoroughly
    using a glass or agate spatula. The use of metal spatulas
    must be avoided since it may lead to metal abrasion and
    discoloration of the ceramic.
    Keep workplace clean; (metal) dust and dirty brush water
    may cause problems (such as formation of bubbles).
    Insulating liquids must not be applied too thickly.
  • Ceramic materials should not be mixed with modelling
    liquid but with distilled water when remixing them.
    It must also be ensured that the mixture is free from
    bubbles. A homogeneous moisture level of the layered
    ceramic must be achieved. Do not keep re-wetting or
    allow it to dry out.
  • Sandblasting the structure with AL2O3 after the first firing
    may cause the formation of bubbles.
Shade too grey / too pale
  • When mixing all ceramic materials ensure that no bubbles
    are formed. Make sure that the liquid is added to the
    powder from the side and stir the mixture thoroughly
    using a glass or agate spatula. The use of metal spatulas
    must be avoided since it may lead to metal abrasion and
    discoloration of the ceramic.
    Keep workplace clean; dust and dirty brush water may
    cause problems (such as formation of bubbles).
    Insulating liquids must not be applied too thickly.
  • Insulation (separating) material residue must not be left
    on the ceramic surface. Do not use baby oil or similar
    liquids for insulating. Contact with the freshly insulated
    antagonists (opposing jaw) can lead to problems.
  • Firing temperature too high or too low: ensure correct
    firing parameters and firing temperature.
  • Too much TRANSPA DENTINE and/or ENAMEL used.
    Not enough BASE DENTINE used.
  • Veneer thickness insufficient; thickness of the ceramic
    layer of ≥0.6 is required to ensure reliable shade
    reproduction.
  • Ceramic materials should not be mixed with modelling
    liquid but with distilled water when remixing them.
    It must also be ensured that the mixture is free from
    bubbles. A homogeneous moisture level of the layered
    ceramic must be achieved. Do not keep re-wetting or
    allow it to dry out.
  • Incomplete predry; liquid did not completely evaporate
    during firing.
Excellent match with the shade guide but considerable...

...deviation after seating (appears too dark).

A discolored die may be the cause. Therefore the shade
of the die must be checked and the die must be coated
or bleached if necessary. Use of Vita Simulate (prep shade)
material is highly recommended.

Errors during firing
  • Ensure good marginal adaptation of the materials.
    If necessary, use a dry and clean brush to smooth these
    areas before firing.
  • When firing bridges, always separate down to the
    substructure in the interdental spaces prior to the first
    dentine firing. Shrinkage of the ceramic always occurs in
    the thickest area; therefore a uniform layer thickness is
    recommended. Do not use any dry and saw-toothed
    instruments. These may cause the ceramic to become
    detached and separate from the surface of the substructure.
  • Crown has a "lifeless" appearance or insufficient translucency
    (incorrect liquid may have been used).
  • Crown has a glassy appearance or round edges after
    firing: check firing muffle!
  • Incorrect furnace parameters or defective vacuum pump.
  • Incorrect predrying; clouding, greyish discoloration.
Pinholing in the surface
  • When mixing all ceramic materials ensure that no bubbles
    are formed. Make sure that the liquid is added to the
    powder from the side and stir the mixture thoroughly
    using a glass or agate spatula. The use of metal spatulas
    must be avoided since it may lead to metal abrasion and
    discoloration of the ceramic.
    Keep workplace clean; dust and dirty brush water may
    cause problems (such as formation of bubbles).
    Insulating (separating) liquids must not be applied too
    thickly.
  • Ceramics should not be mixed with modelling liquid but
    with distilled water when remixing them. It must also be
    ensured that the mixture is free from bubbles. A homogeneous
    moisture level of the layered ceramic must be
    achieved. Do not keep re-wetting or allow it to dry out.
  • The correction porcelain should not be applied in insufficient
    portions. Make sure it does not dry out too
    much. If necessary use a liquid which keeps it moist over an extended period.
  • Avoid frequent removal (suction) and rewetting of the
    material; ensure homogeneous moisture level.
  • Wet ground surfaces before applying ceramic material (do not use oily liquids such as Interno Liquid).
Black specks in the ceramic
  • When mixing all ceramic materials ensure that no
    bubbles are formed. Make sure that the liquid is added to
    the powder from the side and stir the mixture thoroughly
    using a glass or agate spatula. The use of metal spatulas
    must be avoided since it may lead to metal abrasion and
    discoloration of the ceramic.
  • Keep workplace clean; (metal) dust and dirty brush water
    may cause problems.
  • Do not apply insulation (separating) liquids too thick. Do not use baby oil or similar liquids.
Cracking
  • To support the structure, model in reduced tooth size in
    order to achieve a uniform layer thickness of the ceramic.
    Ensure cuspal support of the posterior area.
    Ensure U-shaped modellation of the interdental spaces.
  • Avoid heat development at the surface.
  • Base dentine washbake must be applied in accordance
    with the working instructions to achieve good wetting
    of the surface. The required temperature must be adhered
    to in order to ensure correct melting of Base Dentine.
  • When firing bridges, always separate down to the substructure.
    Shrinkage of the ceramic always occurs only
    in the thickest area. Therefore a uniform layer thickness
    is recommended. Do not use any dry or saw-toothed
    instruments. The use of these instruments can cause
    the ceramic to become detached and separated from
    the surface.
  • Ensure correct firing parameters and firing temperature.
    For the muffle test, use a mirror to look into the firing
    chamber and check whether the muffle is firing properly.
  • Grind the surface of the ceramic with diamond abrasives.
    Avoid developing heat when grinding.
    When using blunt diamonds, do not increase the grinding
    pressure but replace the abrasive instrument. When
    using a turbine, water cooling must always be ensured.
  • Do not use firing trays with metal pins.
Clouding
  • Ensure correct firing parameters and firing temperature.
    For checking carry out muffle test with mirror (optimum
    temperature range: 200 to 300°C).
  • Insulation (separating) material residue must not be left
    on the ceramic surface. Do not use baby oil or similar
    liquids for insulating. Contact with the freshly insulated
    antagonists (opposing jaw) can lead to problems.
  • The correction material should not be applied in insufficient
    portions. Make sure it does not dry out too
    much; if necessary use a liquid which keeps it moist over
    an extended period (VITA MODELLING FLUID or add
    a drop of VITA Interno Fluid).
  • Firing temperature too low.
    Tip: Carry out WINDOW test
  • Avoid frequent removal (suction) and rewetting of the
    material; ensure homogeneous moisture level.
  • Incomplete predry; liquid did not completely evaporate
    during firing.
Bonding problems - all-ceramic substructure to veneering ceramic
  • Base dentine washbake must be applied in accordance with the working instructions to achieve good wetting of the surface. The required temperature must be adhered to in order to ensure correct melting of Base Dentine. Recently layered ceramic must not be preheated too quickly or at excessive temperatures.
  •  When filling interdental spaces during bridge correction, do not vibrate the material until dry, otherwise the material will not bond. Interdental spaces should be wetted with an oily liquid (e.g. VITA INTERNO Liquid, do NOT use baby oil) before filling.
Marginal shrinkage of the ceramic
  • Model the substructure to a reduced tooth size to support and ensure a uniform layer thickness of the ceramic. Ensure cuspal support of the posterior area. Ensure U-shaped modellation of the interdental spaces.
  • Ensure good marginal adaptation of the materials. If necessary, use a dry and clean brush (brush No. 10) to smooth these areas (from incisal to cervical) before firing.
  • When firing bridges, always separate porcelain down to the substructure in the interdental spaces. Shrinkage of the ceramic always occurs in the thickest area; therefore a uniform layer thickness is recommended. Do not use dry or saw-toothed instruments. These may cause the ceramic to become detached and separate from the surface of the substructure.
  • If a rubber polisher is used before finishing, the surface must not be wetted with liquid afterwards. It must first be cleaned. It is not sufficient to clean it with a steam cleaner or with water. Silicone residue at the surface must be removed mechanically using a goat-hair brush.
  • Insulation material (separator) residue must not be left on the ceramic surface. Contact with freshly insulated antagonists (opposing teeth) can lead to problems.
