John MacSpadden and Ben Johnson. Both introduced the concept of manufacturing and utilizing Ni-Ti instruments of a greater taper compared to conventional ISO tapers 0.
The greater tapered instruments utilize tapers from 0. The advantages of these greater tapered instruments are as follows:. The diameter of the instrument below increases 0.
The diameter of the greater tapered instrument below increases 0. In addition, the uncanny flexibility of Ni-Ti allows these greater tapered files to retail flexibility to negotiate through even the most curved canals. A greater tapered stainless steel instrument would be very stiff and inappropriate for use in curved canals.
The introduction of sophisticated computer modeling and multi-axis CNC grinding machines has allowed manufacturers to push the boundaries of instrument design and development. With the clinical acceptance of Ni-Ti instruments throughout the endodontic community, it is only natural and logical for general dentists to also begin accepting these instruments as the standard for endodontic procedures. Therefore the need to compete and provide the best Ni-Ti solutions for both general dentists and endodontic specialists are paramount for the future success of any manufacturer.

Originally posted by Jonathan Mac Hi all, I use a K-3 with two memory cards - 1 is a standard card that records everything I shoot and 2 is a FlashAir card.
Could size be an issue?? Originally posted by Jonathan Mac why is the camera using cards formatted in different ways It depends on the manufacturer and most of all, the user.
That is why most manuals advise to format the SD cards in camera. The message you got on your phone indicates perhaps that the card exceeds the amount of memory it can process. So the total of the phones internal memory plus perhaps an extra card, to have more memory, and the card in the cardreader are all added up.
In the manual of the phone you can find how much extra memory it can process. But on the other hand, I can have handled the wrong end of the memory stick. I would still look at size. My K would take a few pictures at first, but it would eventually fail to write to any memory over 32Gb. This was a problem centered on the K itself, not on a reader. Facebook Twitter Digg.
