(Note: The Milton Syringe is no longer available. Its technology has been absorbed into other products, principly the Precision Endo Obturating Cartridge Syringe which is now our standard. We leave this link here for continuity.)
The quick answer to the question is that with the control available with the new syringe, overfills can be avoided with some simple techniques which are taught in our courses. (I'll give you a hint. The answer is that it's actually pretty hard to overfill. You have to really try.)
The new Milton Syringe is the smallest endodontic syringe in existence. It is essentially a length of 25 gauge tubing which is used as the syringe barrel and a piece of stainless wire used as a plunger.
The important part is how it is filled and used. It is so small that the only practical way to fill it is with another syringe. In this instance with the new Precision Endo Obturating Cartridge Syringe, or with the Original Precision Endo Syringe if you still have one.
With the Milton Syringe you can control cement flow so well that you can not only decide WHETHER you want a "puff" but HOW BIG.
