Ivoclar Vivadent Tetric Ceram HB Instrucciones De Uso página 2

– if a sufficiently dry operating field cannot be established
or if the recommended application technique cannot be
applied;
– if the patient is known to be allergic to any of the
ingredients in Tetric Ceram HB
Side effects
In rare cases, components of Tetric Ceram HB may cause a
sensitizing reaction in patients with a hypersensitivity to
any of the material's ingredients. In these cases, the
material should not be applied.
To avoid irritation of the pulp, protect deep portions of the
cavity preparation in close proximity to the pulp with a
suitable pulp/dentin protector (place a calcium hydroxide
liner in areas close to the pulp).
Interaction
Materials containing eugenol or clove oil may hamper the
polymerization of composites. Such materials should
therefore not be used in conjunction with Tetric Ceram HB.
Cationic mouth rinses and plaque disclosing agents
containing chlorhexidine may cause discolouration.
Application
1. Shade selection
Clean the teeth prior to shade selection. The teeth should
still be moist for shade selection.
2. Isolation
Appropriate isolation is essential. The use of a rubber dam
is recommended.
3. Cavity preparation
The cavity is prepared according to the principles of the
adhesive technique, i.e. preserving the tooth structure. Do
not prepare any sharp internal edges or additional under-
cuts in caries-free areas. Remove the caries and/or the old
restoration, which dictates the proportions of the cavity.
4. Pulp protection / Base / Liner
Do not place a base/liner if not required. If the cavity is very
deep, cover the areas close to the pulp with a calcium
hydroxide material and then cover this layer with a
pressure resistant cement (e.g. glass ionomer cement such
as Vivaglass ® Liner or a zinc phosphate cement such as
PhosphaCEM ® PL). Leave the remaining surface of the
cavity free for bonding with a dentin-enamel adhesive such
as Syntac ® , Excite ® , or AdheSE
5. Placement of matrix / interdental wedge
Place a matrix in cavities extending into the proximal area
and secure it with a wedge.
6. Conditioning / Application of the bonding agent
Conditioning and application of the bonding agent accor-
ding to the Instructions for Use of the product in use. Given
the coordination of Ivoclar Vivadent materials, we recom-
mend using Syntac (with phosphoric acid etching) or Excite
(with phosphoric acid etching) or the AdheSE self-etching
adhesive
7. Application of Tetric Ceram HB
It is advisable to coat the cavity with a layer of a flowable
composite such as Tetric Flow of max. 1 mm (preferably
0.3 to 0.5 mm) to facilitate the marginal adaptation of
high-viscosity Tetric Ceram HB.
Apply Tetric Ceram HB in increments of max. 2.5 mm and
adapt the material to the cavity walls with a suitable
instrument (e.g. P1 instrument). Light cure each increment
with a polymerization unit 500 mW/cm
20 seconds. Hold the light emission window of the curing
light as close to the restorative as possible. If a metal
matrix has been applied, light cure from the bucco-proximal
and/or linguo-/palato-proximal aspect after having removed
the matrix.
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
or finishing strips. Check occlusion and articulation and
make appropriate grinding adjustments to prevent
premature contacts or undesired occlusal deflections on the
surface of the restoration. Polish the restoration to a high
