The technique of brushing has not changed for yours.  One quarter to one half inch of toothpaste on a wet brush would be stroked first on the tops of the teeth.  Then proceed to the gum line on both sides of each tooth.  Either small circular motions, vertical motions or horizontal motions are acceptable.  The small motion should not drag the bristles across multiple teeth, but should create a vibratory motion of the bristles on the teeth to agitate the toothpaste into lather.
