Why use an One-Step obturator?

A safe and effective root filling system.

OneStep® is the second generation of obturators from CMS Dental. The product was developed due to a request from dentists who wanted an obturator without a handle. It gave them a better working area and space to perform the treatment.

Like SoftCore®, the OneStep® obturator consists of a radiopaque plastic core surrounded by natural thermoplastic gutta-percha. The plastic core is available in ISO sizes # 20-70.

Root canal filling with OneStep® is easy and provides a perfect apical seal. OneStep® can be used for root canal fillings instrumented with traditional hand files as well as with all known rotary file systems on the market.


It is a quick, easy and safe method.
Why is it?

Because the solid core ensures:
a) That gutta-percha gets right down to the apex.
b) That a certain lateral pressure is applied, forcing the gutta-percha into lateral canals and outlets. 

Three good reasons:


Warming up an obturator takes 1 min.

Up to 4 obturators can be hung in the oven at a time.

It takes 5-10 seconds to insert an obturator.


You hold the handle with the tweezers so that the tip of the tweezers corresponds to the working length before placing it in the oven. Then simply insert it. Once the gutta-percha has hardened - it takes 3 minutes - cut the core to the measured root length. The rest of the core and gutta-percha remain in the root canal.


More than 5 million root fillings have been made with One-Step and about 20 million with the Soft-Core product, which has proven to be a quality product.
One Step is an easy and safe treatment method that provides a dense root filling.

A control X-ray should always be taken to confirm a correct and dense root filling.

Important info about root canal fillings

Before filling a root canal, you need to make sure that the root canal is free of bacteria.

CMS Dental has therefore developed a treatment concept to eliminate bacteria in the root canal, called LAD (Light-activated disinfection), and it consists of a light source and a photosensitizer. The light activates the photosensitizer, which produces reactive oxygen that kills microbes in the root canal in milliseconds. Where light can penetrate and activate the photosensitizer, the method is highly effective and without side effects.

LAD is used after a thorough cleaning of the canal.
