Description
SUPPRA Bond A Plus is a light-curing 5th generation adhesive (two-step adhesive, total etch technique) for bonding restorative materials to dental tissue (enamel and/or dentin). As the primer and the bonding agent are combined in a single bottle, acid etching is the only necessary step before applying the adhesive to dentin and enamel. The adhesive can be applied in direct procedures (resin composite and glass ionomer cements) or indirect procedures (combined to resin cements).
Product Presentation
Package containing a bottle with 6mL of the product and instructions for use.
Basic composition
Active ingredients: MDP (10-Methacryloyloxydecyl dihydrogen phosphate, methacrylate monomers, phot initiators complex, co-initiators and stabilizers. Inactive ingredients: Inert Load (Silica particles) and Vehicle (ethanol).
Product indication
· All classes of direct restoration with composites (class I, II, III, IV and V)
· Adhesive luting (in addition to resin cement) of prosthetic pieces (post/cores, crowns, on lays/inlays, veneers, etc.) made of fiberglass, ceromer, ceramic, resin and metal;
· Adhesive repairs in ceramic and composites;
Precautions and contraindications
- Before using the bonding agent, make sure that the dentin surface is slightly shiny (moistened), but not wet;
- The air used in the whole procedure must be oil and water free;
- The recommended light-curing time for this product depends on the power of the light emitted by the equipment used. The recommended power intensity of the light-curing unit is above 450mW/ cm2 which guarantees the quality of the polymer generated and the quality of the bonding. Light- curing units must have its light intensity checked by radiometer frequently. It is recommended that the patient and the surgeon use protective goggles during the emission of blue light by the light-curing unit;
- Do not apply excess of adhesive to avoid compromising the quality of adhesion and prevent any aesthetic and functional problems. Excessive application of air blasts should also be avoided to prevent air bubbles in the adhesive;
- Do not leave the adhesive at the reach of patients and children;
- The adhesive contains methacrylate monomers. Avoid using the product in patients with allergy to acrylates/methacrylate’s. To reduce risks, minimize the exposure time of the dental tissues to the material when it is not polymerized;
- Wear protective gloves when handling the product. If the product comes into accidental contact with eyes or oral tissues, wash the area abundantly with water;
- Make sure to close the bottle lid after use;
- In deep cavities protect the dentin-pulp complex with a base or liner material. Do not use material that contains Eugenol as a basis to avoid insufficient curing on the surface. The application of high concentration of H2 O2 should also be avoided because it can interfere on the curing process of the adhesive;
- 10. There is no need for shaking the bottle before using the adhesive.
Side effects
The adhesive can cause sensitization reactions in patients who are sensitive to any components of the formula. In this case, the material should not be
used.
Instructions for use
Before starting the treatment carefully read the Warnings, Precautions, Contraindications and possible Side Effects. A. Light curing direct restorations in enamel and/ or dentin:
- Perform prophylaxis of the teeth with pumice and water or with sodium bicarbonate jet;
- Prior to taking the shade make sure teeth are clean and hydrated;
- Anesthesia can be administered if required;
- Properly isolate the area: direct bonding restorations can be adequately performed with rubber dam or relative isolation depending on the case. There are cases where the use of rubber dam is essential;
- Tooth Preparation: Prepare the cavity with minimal reduction of tooth structure as possible;
- Adhesive Application: See specific procedure in item 1 of this manual.
B. Instructions for bonding of indirect restorations:
- Tooth Preparation: Make the isolation of the tooth with rubber dam or relative isolation with lip retractor and use a gingival retraction cord when the margin of the preparation is subgingival, to ensure no contamination while tooth preparation;
2. Properly clean the preparations with pumice and prophylaxis brush/cup;
3. The treatment of the internal surface of the prosthetic parts should follow recommendations according to the classification of the material.
Follow the manufacturer’s recommendations on the cementation process;
4. Adhesive Application: See specific procedure in item 1 of this manual.
C. Instructions for bonding of prefabricated posts:
- Perform a radiographic examination (periapical radiographs) and check the quality of the endodontic treatment;
- Isolate the operative field. Prioritize the use of rubber dam;
- Partially remove the gutta percha from the conduit using a specific drill or appropriate instrument maintaining 3 to 5 mm of gutta percha in the apical region, ensuring the sealing of endodontic fillings;
- Select the prefabricated post according to the diameter of the root canal;
- Prepare the root canal with appropriate drill to adapt it to the post shape. Avoid unnecessary removal of tooth structure.
- Adhesive application: See specific procedure in item 1 of this manual.
Adhesive application
ACID ETCHING:
- Direct and Indirect Restorations: Apply phosphoric acid at 37% for 15 seconds on both enamel and dentin, according to the type of preparation. Wash the surface with water and dry the cavity so that the dentin does not get dehydrated but also there is no accumulation of water on the surface. If rewetting the dentin for the application of the adhesive system is necessary, use cotton pellets moistened with distilled water or chlorhexidine 2%. By rewetting the dentin we also rewet the enamel, which can be treated using the moist technique.
- Cementation of prefabricated post: Apply phosphoric acid 37% gel into the root canal and remaining tooth structure for 15 seconds. Wash the area carefully and remove the excess water with absorbent paper cones.
ADHESIVE APPLICATION:
- Direct and Indirect Restorations: Dispense SUPPRA Bond A Plus in a Dappen pot or directly onto a disposable micro-applicator. Apply two layers – one drop for each – of adhesive on the slightly moistened tooth surfaces. The first layer should be applied vigorously by rubbing the adhesive micro-applicator saturated with the product for 10 seconds. Next, the second layer of adhesive – with a new drop – is applied for another 10 seconds and then the area is air blasted gently for 10 seconds to evaporate the solvent. Light cure Suppra Bond A Plus with blue light for 10 seconds.
- b. Cementation of prefabricated posts: With the aid of a disposable micro-applicator, apply two layers – one drop for each – of the product into the root canal vigorously rubbing the adhesive on the walls of the conduit for 10 seconds. Evaporate the solvent with gentle blasts of oil-free air for 10 seconds, and then light cure it for 20 seconds.
OBS.: During the adhesive application for post cementation, avoid accumulation of the product in the apical region. Excess of adhesive in this region
compromises the evaporation of the solvent and polymerization; The recommended cure time for this product depends on the power of the light emitted by the equipment used. The recommended power density of the light curing unit is above 450mW/cm2 which guarantees the quality of the polymer generated and also the quality of the bonding.
