The combination of a round head and straight fissure avoids the necessity of changing burs for the two operations of enamel penetration and side cutting.
The combination of a round head and straight fissure avoids
the necessity of changing burs for the two operations of enamel penetration and
side cutting. Ideally suited to the preparation of minimal occlusal
fissure (Class I) cavities in premolars and molars. An additional feature
is the development of rounded internal line angles which increases the
dispersion of mastication forces.
