SAF System

Although root canals are not round and tapered, the rotary instruments in use today force such a shape because of their limitations.

Welcome to ReDent NOVA, developer of the SAF SYSTEM – minimally invasive endodontic technology enabling complete 3D root canal shaping, irrigation, and agitation. The Self-Adjusting File (SAF) System is a breakthrough in endodontic treatment, based on the concept of adapting the file to the root canal rather than shaping the canal according to the limitations of the rotary endodontic file. The SAF System enables the dentist to perform a minimally-invasive endodontic treatment, according to the original anatomy of the root canal, and to achieve cleaning and shaping with continuous irrigation, thanks to the revolutionary design of the file. The SAF, a Nickel-Titanium lattice-like cylinder, is designed to acquire the natural form of the root canal (oval, C-shaped, with various tapers, etc.). The SAF is not a single-core instrument as other endodontic instruments, which not only allows it to adapt to the form of the canal, but also enables continuous effective irrigation throughout the treatment, to achieve better cleaning of the canal, with the use of Sodium Hypochlorite (NaOCl) or other irrigants.

Together, ReDent NOVA Managing Director Johannes Meyer-Kobbe and Christian Witt, Managing Director of our distribution partner C.Witt, visited the laser manufacturing facility where the Self-Adjusting File (SAF) is produced near Hanover.

The unique lattice structure of the Self-Adjusting File is created using highly precise laser technology, forming the foundation of its ability to adapt to the individual anatomy of the root canal system. The visit provided valuable insights into the manufacturing process and an excellent opportunity to exchange ideas with our production partners on site.

A big thank you to everyone involved for the insightful discussions and the fascinating behind-the-scenes look at the production technology behind the SAF System.

Do you already follow a standardized SAF protocol? A clearly defined clinical workflow helps ensure reproducible results and supports you in your daily endodontic practice.

Our clinical SAF protocol provides the recommended workflow – from glide path preparation and selecting the appropriate SAF size for different root canal dimensions to recommendations for primary treatment and retreatment. While PreSAF is the recommended preparation system, other glide path systems can also be used.

✔ Clear and structured clinical workflow
✔ Instrument selection at a glance
✔ Recommendations for primary treatment and retreatment

The clinical protocol is available in German, English, and Polish – both as a download and as a wipe-clean practice version for use in the treatment room.

🎬 Our new SAF video is now available!

The video premiered last weekend at the VDZE Annual Meeting in Frankfurt. It is now available online in both German and English.

It explains what makes the Self-Adjusting File different: instead of shaping the canal to fit the instrument, the file adapts to the natural root canal anatomy while combining shaping, continuous irrigation, and sonic activation in one integrated workflow.

You can always watch both versions on our YouTube channel and on our website.

Thank you, Frankfurt! ✨

As part of the 23rd VDZE Annual Meeting, we had the opportunity to host a sold-out workshop on the SAF System and were also present with a booth in the dental exhibition throughout both days of the event.

Together with Johannes and Roman, participants discussed current concepts in root canal shaping and disinfection, as well as strategies for managing complex root canal anatomies. We were especially pleased by the lively scientific discussions, where different experiences and perspectives on the diagnosis and treatment of challenging cases were shared.

During the subsequent hands-on session, participants were able to apply and explore these concepts in practice. Beyond the workshop itself, the annual meeting provided many opportunities for engaging conversations and valuable professional exchange.

A big thank you to all participants and to the VDZE for a successful event. We look forward to seeing you again soon!

📍 VDZE Annual Meeting 2026 – We’ll Be There!

On June 19–20, 2026, the endodontic community will gather in Frankfurt am Main for the 23rd VDZE Annual Meeting and the 25th Endodontic Symposium. ReDent NOVA will be there as well, with a hands-on workshop and an exhibition booth.

On Friday morning, we are especially looking forward to our nearly sold-out hands-on workshop:

“Self-Adjusting File: Shaping, Irrigation, and Sonic Activation in One Step – True Innovation in Endodontics”

Johannes and Roman will demonstrate how the SAF System combines shaping, continuous irrigation, and sonic activation within a single integrated workflow.

You can also meet us at the exhibition on both days of the event. Stop by our booth, learn more about the SAF System, and exchange ideas with our team about modern concepts in endodontic treatment.

We look forward to many inspiring conversations and to seeing you in Frankfurt!

Conventional rotary files follow a predetermined shape. As a result, in complex root canal systems, not all areas of the canal are reached and cleaned equally. In addition, mechanical preparation and chemical cleaning are typically performed as separate steps.

The Self-Adjusting File (SAF) takes a fundamentally different approach: instead of adapting the canal to the file and unnecessarily removing tooth structure, the file adapts itself to the individual anatomy of the root canal. Thanks to its three-dimensional lattice design, it enables preparation with continuous irrigation and sonic activation throughout the entire treatment process.

The result is a minimally invasive preparation that respects the natural canal anatomy while combining mechanical preparation and chemical cleaning in a single integrated workflow.

Quality and safety are essential when it comes to dental instruments — especially in endodontics, where precision and process reliability have a direct impact on treatment outcomes.

That is why ReDent NOVA is committed to the highest standards:
Our processes are certified according to ISO 13485, the international quality standard for medical devices.

The SAF System also complies with the requirements of the European MDR and, of course, carries the CE mark. For users, this means documented safety, controlled processes, and regulatory compliance at the highest level.

And there is one more thing that matters to us:
The Self-Adjusting File and its associated systems are manufactured in Germany — with a focus on precision, reliability, and consistent quality.

Because modern endodontics requires not only innovation, but also trust.

Last weekend, we were part of the Endodontic Curriculum of the Dental Chamber of Schleswig-Holstein.

As part of the “Instrumentation” module, the advantages of canal preparation and disinfection with the Self-Adjusting File were discussed in depth and practically explored by the 24 participants. The group consisted mainly of experienced clinicians aiming to further deepen their expertise in endodontics. Thank you for the great exchange!

The focus was not only on the application itself, but also on our vision of efficient and modern endodontics – particularly the necessary paradigm shift in the understanding of preparation and disinfection.

The module was complemented by Gerald Schlumbohm, who presented the Schlumbohm EndoPilot² as a modular solution for endodontic treatment – from working length determination and preparation to ultrasonic activation and thermoplastic obturation. This provided valuable insights into modern, digitally supported workflows in endodontics. Schlumbohm GmbH & Co. KG

Many thanks to Dr. David Christofzik for the excellent organization, the high level of expertise, and the great framework for this exchange.

The first step is crucial.

With PreSAF, instrumentation begins where many endodontic complications arise: establishing a safe and reproducible glide path.

As a rotary glide path file, PreSAF supports the initial mechanical enlargement of the canal and creates a defined starting point for further instrumentation – a key factor in reducing torsional stress, blockages, or canal transportation.

The PreSAF family is clearly structured and covers different clinical requirements. The files can be used individually or in combination:

PreSAF FLARE
for coronal enlargement of narrow canal or***ces (or***ce shaping)

PreSAF GLIDE
ISO 14/.03 for initial glide path preparation at ISO 10

PreSAF PREP
for further preparation – including ISO 21 with a regressive taper (5% – 4% – 2%) as an ideal preparation for the SAF 1.5 mm

Manufactured from heat-treated controlled memory nickel-titanium and produced in France, the instruments offer controlled flexibility and high manufacturing quality.

And importantly for daily practice:
PreSAF is not system-bound. The files are compatible with standard endodontic motors and can be easily integrated into existing workflows – even without the SAF system.

At the same time, PreSAF provides a cost-effective solution for mechanical glide path preparation – without unnecessary complexity.

In combination with SAF, a particularly consistent workflow is achieved: first a defined mechanical glide path, followed by three-dimensional preparation with continuous irrigation and sonic activation.
