Adper Single Bond 2 – adhesive 3M ESPE

Adper Single Bond-2
Adper Single Bond 2 Adhesive 3M ESPE is a simple, moist bonding adhesive containing 10%, 5nm colloidal filler.

Adper Single Bond 2 adhesive offers the dental practitioner a wide range of applications. These include bonding to all classes of direct composite restorations as well as procedures involving porcelain, composite, metal repair, set amalgam, root surface desensitization and bonding of porcelain veneers with 3M ESPE RelyX Veneer Cement System and 3M ESPE RelyX Ceramic Primer.

After light curing Adper Single Bond 2 adhesive, it may also be used for amalgam and indirect bonding procedures when combined with 3M ESPE RelyX ARC Adhesive Resin Cement. Compatibility with indirect bonding procedures is due to the low film thickness (approximately 10μm) of cured Adper Single Bond 2.

Adper Single Bond 2 adhesive is available in two delivery systems, a unit dose delivery and a multi-use vial dispenser.

Use of etchant is critical for both enamel and dentin surfaces

Precautionary Information for Patients and Dental Personnel 3M ESPE Scotchbond Etchant contains Phosphoric Acid. Contact with eyes or skin may cause burns. Wear suitable protective clothing, gloves and eye/face protection. In case of contact, flush area with plenty of water and seek medical advice.

Precautionary Information for Patients
This product contains substances that may cause an allergic reaction by skin contact in certain individuals. Avoid use of this product in patients with known acrylate allergies. If prolonged contact with oral soft tissue occurs, flush with large amounts of water. If allergic reaction occurs, seek medical attention as needed, remove the product if necessary and discontinue future use of the product.

Precautionary Information for Dental Personnel
This product contains substances that may cause an allergic reaction by skin contact in certain individuals. To reduce the risk of allergic response, minimize exposure to these materials. In particular, avoid exposure to uncured product. If skin contact occurs, wash skin with soap and water. Use of protective gloves and a no-touch technique is recommended. Acrylates may penetrate commonly used gloves. If product contacts glove, remove and discard glove, wash hands immediately with soap and water and then re-glove. If allergic reaction occurs, seek medical attention as needed.

Hazardous Information
Adper Single Bond 2 adhesive is a flammable material.

Recommendations
Use 3M ESPE Vitrebond Light Cure Glass Ionomer Liner/Base in areas of deep cavity excavation such as Class I and II restorations. If pulp exposure has occurred, use a minimum amount of calcium hydroxide followed by an application of Vitrebond liner/base.

Adper Single Bond 2 adhesive will bond to Vitrebond liner/base whether or not the ionomer was treated with etchant. Adper Single Bond 2 adhesive includes an etch of enamel and dentin as a part of the procedure. It is recommended that the surfaces be left moist after rinsing. Excess surface moisture should be removed by blotting.

Adper Single Bond 2 adhesive is cured by exposure to visible light. The light curing times instructed with this product assumes the use of a 3M ESPE light curing unit or other dental visible curing light of comparable intensity. Curing lights should be checked often for proper output using a reliable light metering system.

Air used for drying should be free of oil and water contaminants.

Sensitivity
Some patients may experience transitory postoperative sensitivity. The risk of sensitivity can be minimized by the following measures:

1. Tooth Preparation
1.1. Remove minimal tooth structure.
1.2. Use proper isolation. Use of a rubber dam is highly recommended. Use adequate pulp protection. Use a glass ionomer or resin-modified glass ionomer liner/base (Vitrebond liner/base) in areas of deep excavation.

2. Adhesive Application
2.1. Use of compressed air is not recommended to remove pooled water remaining after the etch step—blot excess moisture from the preparation using a cotton pellet or mini sponge.
2.2. Apply adhesive immediately after blotting.

3. Restorative
3.1. Place restorative material in increments, curing each increment separately. Adequately cure restorative according to instructions for shade and thickness of restorative and light exposure time.
3.2. Adjust occlusion carefully.  Check for hyperocclusion, particularly in lateral excursion contacts.

Etchant Syringe Assembly
1. Protective eyewear for patients and staff is recommended when using the delivery system.
2. Prepare the delivery system: Remove cap from etchant syringe and SAVE. Twist a blue disposable tip securely onto the syringe. Holding the syringe with the tip away from the patient and any dental staff, express a small amount of etchant onto a dispensing pad or a 2×2 gauze to assure that the delivery system is not clogged.

If clogged, remove the dispensing tip and express a small amount of etchant directly from the syringe. Remove any visible plug, if present, from the syringe opening. Replace dispensing tip and again express etchant. If clog remains, discard dispensing tip and replace with a new one. Bend the dispensing tip to a desired angle. Place bend midway along tip. Do not bend dispensing tip at its hub as this may cause the tip to break free.

3. Delivery system storage: Remove used dispensing tip and discard. Twist on storage cap. Storage of the delivery syringe with a used dispensing tip or without storage cap will allow drying of the etchant and consequent clogging of the system. Replace storage cap with a new dispensing tip at next use.
4. If desired, the etchant may be extruded onto a dispensing pad and applied with a brush or other appropriate instrument.
5. If a liquid etchant is desired, the etchant may be dispensed into a dappen dish and stirred to increase its fluidity.
6. Disinfection: Discard used dispensing tip. Replace syringe cap. See Storage and Use section for disinfection.

Directions

Instructions for direct light cure restorations in enamel and dentin

  1. Isolation: Rubber dam is the preferred method of isolation.
  2. Cavity preparation: Prepare cavity with minimal tooth reduction. Bevel cavosurface enamel margins.
  3. Etching: Apply Scotchbond etchant to enamel and dentin. Wait 15 seconds. Rinse for 10 seconds. Blot excess water using a cotton pellet or mini-sponge. The surface should appear glistening without pooling of water.
  4. Adhesive: Immediately after blotting, apply 2-3 consecutive coats of adhesive to etched enamel and dentin for 15 seconds with gentle agitation using a fully saturated applicator. Gently air thin for five seconds to evaporate solvents. Light cure for 10 seconds.
  5. Restorative placement, cure and finishing: Refer to manufacturer’s instructions for placement, cure and finishing of restorative materials.

Instructions for bonding porcelain veneers

  1. Silane treatment: Porcelain bonding surfaces should have been etched using hydrofluoric acid by the dental laboratory. Apply RelyX Ceramic Primer (No. 2721) to the bonding surface of the veneer. Dry for 5 seconds.
  2. Clean the prepared teeth in preparation for seating and bonding using a plain flour of pumice slurry. Rinse thoroughly and dry.
  3. Try in veneer with 3M ESPE RelyX Try-In Paste. After try in, isolate from adjacent teeth with clear matrix strip.
  4. Etching: Apply Scotchbond etchant to both enamel and dentin. Wait 15 seconds. Rinse for 10 seconds. Blot excess water using a cotton pellet or mini-sponge. The surface should appear glistening without pooling of water. An additional 15 second etch time may be appropriate for teeth that were not prepared using a diamond or bur. Residual organic matter can also require additional etch time.
  5. Adhesive: Immediately after blotting, apply 2-3 consecutive coats of adhesive to etched enamel and dentin for 15 seconds with gentle agitation using a fully saturated applicator. Gently air thin for five seconds to evaporate solvents. Do not light cure.
  6. Adhesive application to veneer: Apply 1 coat of adhesive to the acid etched, silane treated veneer. Dry thoroughly. Do not light cure.
  7. Luting material application to veneer: Apply RelyX Veneer Cement to the bonding surface of veneer.
  8. Seating and curing: Carefully seat the veneer. Clean excess luting cement from the veneer margins. Cure each area of the veneer for times recommended by the luting cement manufacturer. We recommend curing the gingival margin first, followed by the body and the incisal margin. Avoid direct contact with the light-guide during initial curing.

Instructions for bonding to composite and set amalgam

  1. Isolation: Rubber dam is the preferred method of isolation.
  2. Roughen the existing material: Roughen the surface of existing amalgam or composite using either a bur, diamond or a sandblast technique.
  3. Etching: Apply Scotchbond etchant to enamel, dentin and existing restorative material. Wait 15 seconds. Rinse for 10 seconds. Blot excess water using a cotton pellet or mini sponge. The surface should appear glistening without pooling of water.

Gently air thin for five seconds to evaporate solvents. Light cure for 10 seconds. Apply 2 additional coats of adhesive. Dry gently for 5 seconds. Light cure for 10 seconds.
  4. Remove the oxygen inhibited layer with a moistened gauze.

Instructions for Amalgam and Indirect Bonding Procedures (using RelyX ARC adhesive resin cement)

Physical properties of today’s esthetic indirect restorations require that they be bonded into place to maximize the strength of the restoration as well as the tooth. A general perception may exist that light cured adhesives cannot be used for indirect restorations. It’s true that many conventional light cured adhesives have a higher film thickness and cannot be used under a fixed prosthesis.

However, Adper Single Bond 2 adhesive is ethanol/water based, has a low film thickness (approximately 10μm) and should not interfere with the seating of indirect restorations.

Note: Care is required with any bonding agent used beneath precision castings because added film thickness may preclude accurate seating. Avoid adhesive pooling in areas of the preparation that would effect the fit of any prosthetic device.

Instructions for bonding endodontic posts

  1. Prepare the endodontically treated tooth to receive the post (a root apex sealer and gutta percha filling approximately one third of the root canal are recommended). Trial fit and adjust post as needed. Bond to cast posts can be enhanced by using an air abrasion system and then applying RelyX Ceramic Primer. Dry for 5 seconds.
  2. Etching: Apply Scotchbond etchant to the prepared tooth. Wait 15 seconds. Rinse for 10 seconds. Dry for 2 seconds. Remove excess moisture with an absorbent paper point.
  3. Adhesive: Apply a uniform coat to etched enamel and dentin. Remove excess pooled adhesive with absorbent paper point. Air thin for five seconds to evaporate solvents.
  4. Light cure for 10 seconds. (A light transmitting post of appropriate size may be used for additionalcuring).
  5. Dispense the appropriate amount of cement onto a mixing pad and mix for 10 seconds.
  6. Apply cement to the bonding surface of the preparation (in and around canal using a periodontal probe). Place a thin layer of mixed cement on post.
  7. Seat the post. While holding in place remove excess cement. Light cure for 40 seconds from the occlusal surface to allow immediate placement of core build-up material.

Instructions for bonding amalgam to tooth structure

  1. Isolation: Rubber dam is the recommended method of isolation.
  2. Cavity preparation: Prepare a standard amalgam cavity preparation. Roughen residual restorative materials with an air abrasion system or a bur.
  3. Matrix application: Lightly lubricate the inner surface of the matrix band with hard wax or petroleum jelly
    before placement.
  4. Etching: Apply Scotchbond etchant to enamel, dentin and any residual restorative. Wait for 15 seconds. Rinse for 10 seconds. Blot excess water using a cotton pellet or mini sponge. The surface should appear glistening without pooling of water.
  5. Adhesive: Immediately after blotting, apply 2-3 consecutive coats of adhesive to etched enamel, dentin and any residual restorative material for 15 seconds with gentle agitation using a fully saturated applicator. Gently air thin for five seconds to evaporate solvents.
  6. Light cure for 10 seconds.
  7. Dispense the appropriate amount of cement onto a mixing pad and mix for 10 seconds.
  8. Use a brush or appropriate applicator to place cement in adhesive-sealed preparation. Triturate amalgam during placement of cement.
  9. Condense and burnish amalgam in the usual way.
    Instruct patient to avoid applying any pressure for 10-15 minutes.
