The IOS FastScan is the only system in which
you hold the wand still while the camera
moves within the wand. It is counterbalanced
so that as the camera moves across its
40 mm path, you are not able to feel it
moving. This single capture is equal to four
or five still frames taken with another system.
Figure 13: My favorite part of the Reverse Preparation Technique and
the best thing about electric handpieces is the ability to turn down
the rpm to 5,000 and turn off the water. My KaVo ELECTROtorque
(Charlotte, N.C.) has all its torque at 5,000 rpm but spins slowly enough
that I can turn off the water without overheating the tooth. For once, I
can see enough to smooth the margin well.
Figure 14: At this point I know the preps are finished because the depth
cuts are gone. Before I developed this technique, I used to prep teeth
and guess when they were done. I always request a prep guide with my
BioTemps to see if I missed a spot, although this is highly unlikely with
depth cuts. Now I know the BioTemps will seat completely.
