Ivoclar Vivadent Tetric EvoCeram Mode D'emploi page 2

– Restorations in the posterior region (Classes I and II)
– Veneering of discoloured anterior teeth
– Splinting of mobile teeth
– Extended fissure sealing in molars and premolars
– Repair of composite and ceramic veneers
Contraindication
Placement of Tetric EvoCeram restorations is contra-
indicated:
– if a dry working field cannot be established, or if the
stipulated technique cannot be applied.
– if a patient is known to be allergic to any of the
ingredients in Tetric EvoCeram
Side effects
In individual cases, components of Tetric EvoCeram may
lead to sensitization. Tetric EvoCeram 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 (apply a calcium hydroxide-based
preparation in areas close to the pulp).
Interactions
Substances containing eugenol/oil of cloves may inhibit the
polymerization of composite materials. Consequently,
application of such materials together with Tetric EvoCeram
must be avoided.
Discolouration may occur in combination with cationic
mouthwashes, plaque disclosing agents, and chlorhexidine.
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, 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 and subsequently use a
pressure-resistant cement (e.g. a glass ionomer cement,
such as Vivaglass ® Liner, or a zinc phosphate cement, such
as PhosphaCEM PL). 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
(with phosphoric acid etching) or the AdheSE
adhesive.
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, P1
instrument). Use a special contact point instrument (e.g. the
bifurcated OptraContact) for large cavities where the
contacts are difficult to create.
