Video of New Fine-Cut Endo ContraAngle

A look at the Endo Cartridge Syringe

At long last for we are setting a definite release date for the new Fine-Cut Endo Contra-Angle. That date is NOW.

Every one of my inventions periodically undergo a fine-tuning reassessment process. Some have even said it is a brutal Gestalt-like reevaluation of what has gone before.

The Endo Contra Angle has gone thru one of these already. We discovered after a few years that since it took considerable torque to translate rotary movement into linear oscillation, that the drive-shaft (the part that tightens into the straight nosecone) was wearing out and since it had to be made of stainless steel to allow sterilization, there was little we could do about it. So instead of fitting on a doriot type straight handpiece, we decided to make it fit a European (E-Type) motor.

More recently (September 13, 2007) we have added a RetroFiler attachment to the FineCut Endo Contra Angle. It attaches with a small screw and receives a Fine-Cut File which can be bent to any size or angle to enable the dentist to access the apical foramen to clean it and prepare it for retrofilling. The filing action is similar to the regular files except that access is much better and the file does not float.

With the recent emphasis on what we have always called Washed Field Endo and some people refer to as HydroDynamic irrigation, there is now a smooth tapered instrument which can be used in place of the files and is intended to irrigate without filing for all those who prefer rotary filing but want the advantage of irrigating a canal while it is still small, size 15 in fact, to prevent the accumulation of debris. Although no pictures are yet available think of them as a size 15 Fine-Cut File without flutes i.e exactly the size and shape of a size 15 finger plugger.

The latest comes about because of the complexity of the internal parts and the wear and tear on the bearings, drive shafts and rocker arm. Minor changes had resulted in many different versions in dentists' hands. This in turn made it difficult to offer repair service or advice on maintenance but that meant many hours in the shop.

Part of the reason was that we always tried to "keep the 747 flying while remodeling it" i.e. keeping dentists up on the latest engineering and keep them in business.

This time we decided to use the winery slogan instead that "we will sell no contra-angle before it's time." Thus the delay.

We sought to make it reliable to reduce down time.

We sought to make it quieter which was no small feat given that the file holder mechanism itself vibrated when it changed directions as many as 20,000 times per minute.

We sought to make it completely compatible with the files that go in it.

We sought to make it less expensive.....well, three out of four ain't bad.

But considering the economics of it the system is actually economical in that it is possible to prepare a canal from size 15 to size 50 in about 45 seconds with NO DANGER OF BREAKAGE of files. Furthermore, many times the number of files needed to prepare a canal is reduced to one or two.

One of the major advantages of this contra-angle is that because the file moves in and out of the canal only about a millimeter, there is a constant churning of the fluid in the canal. By the simple expedient of adding fresh water to the pulp chamber, the entire canal is flushed clean of debris TO THE DEPTH OF THE FILE, every TWO SECONDS.

Even if you are now using rotary NiTi which is notorious for burnishing debris into the canal walls, it would be worth it to have one of these contra-angles to do nothing but IRRIGATION.

We have beefed up the bearings inside and put them in their own "cage" to enable modular assembly and disassembly for service.

And along the way we made the head even smaller although it was already the smallest on the market. Now you only need about 4 MM in the molar area. And we've made changing files even easier while we were at it.

Production is in progress and we began delivering new product March 1, 2007. We offer trade-ins on older versions for those who want them. As usual our trade in policy is very generous. We have as much interest in you doing good endo as you do.

We are now taking orders for contra-angles, trade-ins and upgrades. To save you the trouble of looking it up,

  • the price is $699 and you can get a $100 trade in on any giromatic or other endo handpiece OR
  • Special Labor Day to Columbus Day Offer...$699 INCLUDES MTI E-Type Air Motor OR
  • New LP Model Fine Cut Endo Cartridge Syringe.

If you are not familiar with the Fine-Cut system, it uses specially designed files with very small (less than 4mm tall) heads and Fine-Cut blades. And yes these are the same ones that fit our sonic adapters and the Sonicaire adapter . If you already have some of these files they will fit. If not, they are available, as before in 22mm, 25mm, and 29mm lengths in sizes 15-40. Some veterinary dentists use longer ones and for them we have 40mm lengths available on special order.

Fine-Cut Hand Files

These contra-angles will fit most standard European or (E-Type) connector motors, air or electric . We recommend the Lynx Air Motor and unless you are sure you already have a motor that will work, we send one with each new customer order. If when you get it, you find that you already have one you can use, simply box up the air-motor and send it back for full credit. The price of this motor is $289.

Opt-In mailing list request: Federal law specifies that if you do not want email from a particular address that you can simply request to be off that list. AOL goes one farther, it threatens to shut off the mail from any ISP that sends too many emails to AOL users even if they comply with that law.

If you don't want to hear future information on our Fine Cut Endo Files, or the Fine-Cut Endo Contra-angle or the Cartridge Endo Syringe or any of the other products you can see at www.BetterEndo.com simply return this email with the subject changed to "remove". Otherwise you are likely to get more information that may help you make dentistry easier and more fun.

Therefore we no longer send email to AOL users, and AOL users lose a lot of valuable information that can help their practice.

If you are an AOLer (or anyone else for that matter) and WANT to receive information in the future on any of these topics:

  • How to avoid file breakage and still prepare a canal in less than a minute.
  • How to seal and fill a root canal with an ADA certified material in less than a minute.
  • How to irrigate a canal without making it overlarge.
  • ...and many more.
