Arkona Masterbond dental adhesive system

Properties:

- class IIa medical device

- composition: mixture of dimethacrylate resins (BisGMA, HEMA, BiSEMA) combined with ethyl acohol, catalysts, inhibitors, photoinitiator (CQ: DMAEMA).

- Masterbond undergoes free radical polymerisation activated by visible light from the blue region (400-500 nm).

- used to: bond the hard tissues of the tooth and composite; improve the marginal seal between the restoration and the tooth; reduce polymerisation shrinkage; prepare the surfaces of restorations prior to their cementation using dual cure resin cements.

Method of use:

1. Carefully prepare the cavity. The composite only adheres to the normal structure of enamel and dentine (b); it will not stick to caries (a).

Careful polishing of the entire cavity wall will help retain the restoration; it will also prevent microchipping (c) of the restoration margin that may occur as a result of chewing food.

2. Etch the entire surface for 30-60 s (a) using Etchgel. It is acceptable to exclude the bottom of the cavity (b) - the composite does not adhere to demineralised tissue. Rinse and dry gently.

Polymerisation time:

- halogen / led lamp (500 - 800 mW/cm2) - 15 sec.

- LED lamp (>800 mW/cm2) - 10 sec.

3. Thoroughly cover the cavity with Masterbond, rubbing it in carefully for a few seconds.

Make sure the whole surface of the cavity is covered with Masterbond as this will ensure a total adhesion of composite to the tooth:

a, b - insufficiently c - correctly.

Blow off the excess material and cure in accordance with the polymerisation table provided.
