Spring Endo File

Denflex is opening
the future with innovative technology.

Spring Endo File

Increased safety and unique flexibility

SPRING ENDO FILE

It is a new concept of endopile designed to dramatically
reduce tip fracture without reducing the cutting force
and to facilitate removal of the fractured part as fracture occurs
at the spring part located outside the root canal even if fracture occurs.


Problems of existing products

Often a situation where the tip is broken and gets stuck in the root canal

If the "fracture occurs at the tip", more than 95% of the cases, the failure to remove the fragment may increase the likelihood of a medical dispute.
Existing products without a spring structure often fracture the tip of the cutting edge at the apical end during root canal treatment,
and it is often difficult to remove it.It is not easy to prevent tip fracture as the operator cannot detect that the cutting edge is overloaded.
In patients with poor mouth opening, both the patient and the surgeon have a hard time treating the posterior teeth.
Due to the straightness of the file, a large amount of tooth removal is required. Since there is no structure to buffer the overload applied to the cutting edge, the possibility of tip fracture during repeated reuse increases significantly.

Advantages of Denflex Spring Endo File

Increased safety

Spring structure buffers overload on file

The load is distributed toward the spring, and in many cases,
it is broken at the spring part above the root canal, making it easy to remove.
The overload buffer effect of the spring reduces the breakage of the file,
It is a safer endofile designed to occur break at the spring part rather than the cutting edge.
in addition, If the file is overloaded, a characteristic feel and sound are generated during the winding
and unwinding of the spring structure, which may practitioner notice overload.

Unique Flexibility

Even with the spring part bent(60-70 degree), it is able to send 100% rotational power

It is useful for the posterior part of patients who cannot open their mouth wide.
Even if the root canal is bent away from the central axis of the tooth, excessive tooth removal is not necessary.

Cutting Force

Micro-vibration of the spring increases the cutting power.

It improves cutting power by generating micro-vibration.
Due to the micro-vibration, the screw-in phenomenon into the canal of the blade area is significantly reduced.

Increased durability

The spring structure buffers the overload applied to the file.

Our Spring Endo File has increased the number of uses compared to general Endo files, and shows improved results compared to general files in Cyclic Fatigue Resistance Test.

Our test shows that it has the possibility of repeated use of more than 15canal, but it is desirable to set the number of use within 10canal per file as the cutting edge becomes dull as the number of uses increases and the cutting performance decreases.

Precautions

Do not apply force to the tip direction.
Do not apply force in the lateral direction.
Do not test on the resin block, but on the natural teeth. When testing on the resin block,
the correct test cannot be performed due to the spring structure.
