Estelite Sigma Quick – resin-based dental restorative material

Estelite Sigma QuickEstelite Sigma Quick is a dental light-cured, radiopaque, submicron filled composite resin for use in anterior and posterior restorations and is indicated for all carious classes.

Estelite Sigma Quick contains 82% by weight (71% by volume) of silica-zirconia filler and composite filler. A high filler load offers decreased polymerization shrinkage.

All inorganic filler contained in Estelite Sigma Quick is a spherical submicron filler (mean particle size: 0.2 μm, particle size range: 0.1 to 0.3μm) that is designed to deliver excellent gloss retention and wear resistance. The monomer matrix contains Bis-GMA and Triethylene glycol dimethacrylate.

Estelite Sigma Quick implements Radical-Amplified Photopolymerization initiator technology (RAP technology).

Curing time for can be shortened by one-third using a light curing unit with a wavelength range of 400 to 500nm (peak: 470nm) compared to our conventional resin composite. Please see the table depicting the relationship between curing time and increment depth (Indications for filling and curing).

RAP technology facilitates a longer working time for Estelite Sigma Quick.

Estelite Sigma Quick is provided either in SYRINGE or Pre Loaded Tip(PLT).


A1, A2, A3, A3.5, A4, A5, B1, B2, B3, B4, C1, C2, C3, OA1, OA2, OA3, OPA2, BW (Bleach White), WE (White Enamel) and CE (Clear Enamel/Incisal).

  • Opalescent shades (OA1, OA2, OA3) have adequate opacity designed for blocking out the dark shine that comes through the oral cavity (Class III and Class IV restoration). The opalescent shades also serve as a dentin layer for the multi-shade layering technique. Shades OA1, OA2 and BW closely match those of primary teeth. However, they are not designed for masking metal or a darkly stained area such as tetracycline stained.
  • OPA2 is designed for masking slight stain or reconstructing a highly opaque tooth (use as a thin layer at the lingual cavity wall of class III and IV).
  • Please check with your local distributor for available shades.

Indications for filling and curing
Be sure to light-cure Estelite Sigma Quick extraorally and check the time needed for complete hardening of Estelite Sigma Quick with your light curing unit before performing the bonding procedure. The following table illustrates the relationship between curing time and increment depth.

Relationship between curing time and increment depth:


1) Increment depth was determined on the basis of test results performed in accordance with section 7.10“depth of cure”of ISO4049: 2000.

Special notes for the use of PLT

  1. PLTs are designed for single patient use only. Do not re-cap and/or re-use the PLT tip once material has been dispensed for that patient.
  2. Dispensers are not provided for Estelite Sigma Quick. Use a dispenser that fits the PLT of Estelite Sigma Quick. For proper use and proper disinfection, see manufacturer's instructions.
  3. Apply the composite at normal room temperature (18 – 30°C / 62 – 84°F). Material that is too cold might be difficult to extrude.
  4. Use light, controlled pressure to prevent any continued extrusion of material following pressure release.


  1. Store Estelite Sigma Quick at a temperature between 0 – 25°C (32 – 77°F).
  2. AVOID direct exposure to light and heat.
  3. DO NOT use after the indicated date of expiration on the syringe or PLT package.

To safely dispose of excess Estelite Sigma Quick, extrude unused portion from SYRINGE or PLT and light-cure before disposal.

Estelite Sigma Quick – clinical procedure

1. Cleaning
Thoroughly clean the tooth surface with a rubber cup and a fluoride-free paste then rinse with water.

2. Shade Selection
Select the appropriate shade of Estelite Sigma Quick prior to placing the rubber dam using the shade guide provided for Estelite Sigma Quick.
– Complete the shade selection within 5 minutes; desiccated teeth are lighter than wet or moist teeth.
– Lightness (color value) is primary importance on shade selection.
– When wavering in shade selection, select the lighter (high value) shade.
– In case of whitened teeth select the shade a few weeks after the completion of whitening. Whitened teeth may become slight darker.

3. Isolation
A rubber dam is the preferred method to isolate the tooth from contamination.

4. Cavity Preparation
Prepare the cavity and rinse with water. Add bevels to the enamel margins of anterior preparations (class III, IV, V), as well as chamfers to the margins of posterior preparations (class I, II) because bevels and chamfers assist in erasing demarcations between the cavity margins and restoration, thereby enhancing both esthetics and retention.
– Scalloped (undulant) bevel could be desirable depending on the esthetics and retention.
– In case of porcelain/composite repairs, roughen the surface with a bur or a diamond point to prepare the area for adhesion; apply phosphoric acid etch for cleaning; rinse thoroughly with water; air dry thoroughly and treat with a silane coupling agent (such as Tokuso Ceramic Primer) according to manufacturers instructions.

5. Pulp Protection
Glass ionomer lining or calcium hydroxide should be applied if the cavity is in close proximity to the pulp. DO NOT USE EUGENOL BASED MATERIALS to protect the pulp as these materials will inhibit curing of bonding agent and/or Estelite Sigma Quick.

6. Bonding system
Apply light-cured bonding system according to manufactures instructions. We recommend the use of TOKUYAMA BOND FORCE which is a one component, selfetching, light-cured dental adhesive.
– Do not use self-cured bonding systems. We advise that light-cured bonding systems should be used with Estelite Sigma Quick since other types of bonding systems such as self-cured or dual-cured bonding systems may not provide effective adhesion when used with light-cured composite resins. If you want to use self-cured or dual-cured bonding systems, please confirm that such bonding systems are compatible with the light-cured composite resins being used.

7. Dispensing
7-1. PLT Please read (Special notes for the use of PLT) before use.
– Load the PLT into a dispenser that fits the PLT. – Remove the PLT cap. – Extrude the paste directly into cavity or indirectly on the mixing pad.
7-2. SYRINGE Remove the syringe cap. Extrude the paste onto a mixing pad by turning the handle clockwise. Re-cap the syringe immediately after dispensing. – DO NOT apply unnecessary force to the syringe immediately after removing from the refrigerator.

8. Filling and contouring
Fill the cavity incrementally. Increments should not exceed the indicated depth (please refer to the aforementioned table).
– DO NOT mix with other brands of resin composite or other shades of Estelite Sigma Quick to avoid incomplete cure or voids.

9. Curing
Light-cure each increment for at least the indicated time (please see aforementioned table), keeping the curing light tip within a distance of 2 mm from the increment.
– If other brands of composite resins are layered over the cured composite, follow their instructions.

10. Finishing
Shape and polish the restoration. For finishing, use fine finishing diamond points. To erase the demarcation between the composite and the natural tooth rotate a 12 fluted carbide bur slowly along the margins without water. Use finishing metal strips or vinyl strips for proximal surfaces. For polishing, polish with rubber points or any suitable polishing tool, such as PoGoTM (DENTSPLY/Caulk), Sof-Lex (3M ESPE), Identoflex® HiLuster Dia Polishers (Kerr), or D-FINETM Hybrid Diamond (COSMEDENT, Inc.).
