M icromechanical Bonding
It is the microscopically interlocked adhesive and adherent with dimensions of less than 10 m produced by mechanical roughness.
Requirements for adhesion are:
1. To produce good bonding there must be good wetting. 0° contact of adhesive to the adherent ensures complete wetting.
ADVERTISEMENTS:
2. Surfaces being bonded should be clean.
These are classified on the basis of the primary adherent. They are:
(i) Enamel bonding
ADVERTISEMENTS:
(ii) Dentin bonding
(iii) Amalgam bonding.
