Ivoclar Vivadent Tetric EvoCeram - Manual (Page 2)

Application
1. Shade determination
Clean the teeth prior to shade determination. The shade is selected with the
tooth still moist.
2. Isolation
Appropriate isolation, best with a rubber dam (e.g. OptraDam
® Plus), is
required.
3. Cavity preparation
Cavity preparation is carried out according to the requirements of the
adhesive technique, i.e. protecting the tooth structure. Do not prepare sharp,
internal edges or additional undercuts in caries-free areas. The dimensions of
the cavity are generally determined by the extent of the caries or the size of
the old restoration. Bevel enamel edges in the anterior region. For the
posterior region, only the sharp enamel edges should be rounded (finishing
diamonds, 25–40 µm). Caries-free cervical defects are not prepared, only
cleaned with pumice or other suitable cleaning pastes with the help of rubber
cups or rotary brushes. Subsequently, remove all residue in the cavity with
water spray and dry with water- and oil-free air.
4. Pulp protection / Base
Do not apply a base material when using an enamel/dentin bonding agent.
Only cover very deep areas close to the pulp with a calcium hydroxide
material (e.g. ApexCal
® ) and subsequently use a pressure-resistant cement
(e.g. a glass ionomer cement, such as Vivaglass ® Liner). Do not cover other
cavity walls, since they can be used to support the bond with an enamel/
dentin adhesive.
5. Matrix / Interdental wedge
Use a wrap around matrix for cavities affecting the proximal area (e.g. the
selectively thinned OptraMatrix) or a sectional matrix and wedge it.
6. Conditioning / Application of the bonding agent
Condition and apply the bonding agent according to the Instructions for Use
of the product in use. We recommend using Syntac
® (with phosphoric acid
etching) or ExciTE ® F (with phosphoric acid etching) or the self-etching
adhesive AdheSE ® One F.
7. Application of Tetric EvoCeram
–
For an optimum result, apply Tetric EvoCeram in layers of max. 2 mm or
1.5 mm (Dentin shades, Bleach XL) and adapt with a suitable instrument
(e.g. OptraSculpt). Use a special contact point instrument (e.g. the
bifurcated OptraContact) for large cavities where the contacts are
difficult to create.
– Sufficient exposure to the curing light prevents incomplete polymeriza-
tion. For the recommendations regarding exposure time and light
intensity see Table 1.
– When using a metal matrix, additionally polymerize from the buccal or
lingual/palatal after removing the matrix.
– 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
EvoFlow
® ) can be used in a thin initial layer. This optional layer has to be
cured separately (please refer to the respective Instructions for Use).
8. Finishing / Checking the occlusion / Polishing
Remove excess material with suitable finishers (e.g. Astropol
® F) or fine
diamonds after polymerization. Remove proximal excess with diamond or
tungsten carbide finishers, finishing strips, or flexible finishing discs. Check
the occlusion and articulation and apply appropriate grinding corrections to
prevent premature contacts or undesired articulation paths on the surface of
the restorations. Use silicone polishers (e.g. Astropol P, Astropol HP or
Astrobrush) as well as polishing discs and polishing strips to polish the
restorations to a durable high gloss.
Additional information
1. In the case of repair, additional Tetric EvoCeram can be directly applied to
polymerized material. If the Tetric EvoCeram restoration has already been
polished, it must first be roughened and wetted with Heliobond before
fresh Tetric EvoCeram is applied.
2. Tetric EvoCeram should have at least room temperature when applied.
Cool temperatures render the material difficult to extrude.
3. If Tetric EvoCeram is applied from the Cavifil directly in the mouth of
the patient, the Cavifil must not be used for more than one patient
due to hygienic reasons (prevention of cross-contamination between
patients).
4. Syringes or Cavifils should not be disinfected with oxidizing disinfection
agents.
Warning
Unpolymerized Tetric EvoCeram should not come in contact with skin,
mucous membrane, or eyes. Unpolymerized Tetric EvoCeram may have a
slight irritating effect and may lead to a sensitization against methacrylates.
Commercial medical gloves do not provide protection against the sensitizing
effect of methacrylates.
Storage
–
Do not use Tetric EvoCeram after the indicated date of expiration.
– Storage temperature 2–28 °C / 36–82 °F.
– Close syringes / Cavifils immediately after usage. Exposure to light causes
premature polymerization.
– Shelf life: see information on Cavifils, syringes and packages.
Keep material out of children’s reach.
