5
Q
ultrasonic tip selection
A
beavertail - supramarginal surfaces, ortho cement removal
ball point - furcation areas
periodontal - thin straight tip, designed for subgingival
6
Q
ultrasonic tip angulation
A
oblique - similar to bladed instrument, recommended for supragingival/interproximal, may limit access to depth of pocket
vertical - similar to perio probe, recommended for subgingival, can also be used supragingival, maximized access to depth of pocket
