Ivoclar Vivadent Tetric - Manual (Page 2)

Indication
– Class I - V restorations
– Restoration of deciduous teeth
– Extended fissure sealing
– Direct veneers
– Splinting of mobile teeth
– Blocking out of undercuts
– Repair of composite and ceramic veneers
– Inlays/onlays with extraoral post-tempering
Contraindication
– if a dry working field cannot be established or the
prescribed application technique cannot be applied
– if a patient is known to be allergic to any of the
ingredients of Tetric
Side effects
In rare cases, components of Tetric may lead to sensitiza-
tion. Tetric 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 pro-
tector.
Interactions
Substances containing eugenol/clove oil inhibit the poly-
merization of materials based on methacrylate. Conse-
quently, application of such materials together with Tetric
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. Establish reliable isolation, preferably with a rubber dam
(e.g. OptraDam ® Plus).
3. Prepare the cavity according to the requirements of the
adhesive technique.
4. Clean the cavity with water spray.
5. Air dry the cavity.
6. Apply a pulp protector (calcium hydroxide) if needed;
only cover areas close to the pulp and subsequently
apply a pressure-resistant cement (e.g. Vivaglass
® Liner).
7. Apply a matrix (e.g. OptraMatrix ® ) and an interdental
wedge, if required.
8. Apply the bonding agent according to the Instructions
for Use of the product in use. We recommend using
Syntac
® or ExciTE ® F (both with phosphoric acid
etching) or the AdheSE ® One F self-etching adhesive.
9. Apply Tetric to a maximum layer thickness of 2 mm, or
1.5 mm for Dentin shade, and adapt/contour with a
suitable instrument (e.g. OptraSculpt
® ).
The OptraContact ® instrument can be used to selectively
position high-quality proximal contacts.
Polymerize each layer according to the table below.
Hold the light emission window of the curing light as
close to the restorative as possible.
10.Finish the restoration with suitable finishers or fine
diamonds. Subsequently, check the occlusion.
11.Polish with silicone polishers
(e.g. OptraPol ® Next Generation).
