Since 1985, when anyone asked me if I thought that by switching to sonic or ultra-sonic endo that they would be able to prepare a canal faster or easier with a sonic than with the Giromatic ...
I had to say NO.
Were there advantages, yes.
Enough to merit the switch, maybe.
You have to understand that in no sonic or ultra-sonic system on the market does the vibration actually do the cutting.
All that it does is to keep the file moving so that the file can do the cutting.
Since the movement of the file is a waggling motion, back and forth, if the file did actually cut, it would be dangerous because it would cause a ledge.
There were, however, several advantages to Fine-Cut sonic endo.
It is smaller.
Six millimeters in height as opposed to about 12-14 with the Giromatic.
Changing files is a little easier because of the sliding sheath.
The Fine-Cut sonic adapter allows the files to free-wheel and orient themselves to the plane of the curve of the canal and thus minimize adverse torque and stripping.
And there was automatic irrigation.
But did it make it faster ...
NO.
How fast it cut was determined by how many strokes up and down you could make, because you still had to do circumferential filing.
Now the situation is just about optimal.
With the Successor To Sonics (STS) system the up and down motion is done for you in a very controlled manner and is both FAST and SAFE.
As near as I can figure, the preparation is 25-50 times as fast and endo suddenly got easier on your hands and the preparation has gotten simpler.
Now with the Fine-Cut Endo Contra-angle it is even easier and more convenient. It uses the same file holder and thus the same files as the sonic adapter and the STS system.
If you are ready to change for the better, pick one of the dates on the schedule.
Invite your endodontist friends.
Bring your associates.
Invite your dentist friends who might not be getting this newsletter.
