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.

Are you still using EDTA at the end of instrumentation?

In conventional endodontics, chemical cleaning usually follows separate steps:
NaOCl during instrumentation – followed by EDTA for smear layer removal.

With Dual Rinse® HEDP from Medcem, there’s a different approach:
It is mixed directly with NaOCl and provides continuous chemical support throughout the entire instrumentation process.

In combination with the SAF System, mechanical preparation and chemical cleaning occur simultaneously – through continuous irrigation and activation.

The result:
• fewer irrigation steps
• a more efficient workflow
• integrated cleaning from the start

Dual Rinse® HEDP is available in Germany through ReDent NOVA – with or without the SAF Infinitum System.

Strong exchange, inspiring insights, and a clear view of the future of medical technology 🚀 ReDent NOVA participated in the Medical Technology Congress 2026 (mtk26) hosted by NiedersachsenMetall at the Medical Park – a new format bringing together industry, science, medicine, and politics.

We are especially proud that our Head of Clinical Dentistry, Johannes Meyer-Kobbe, led a dedicated SAF forum. The focus: modern endodontic concepts and how innovative technologies are advancing root canal treatment.

The congress clearly demonstrated:
👉 Medical technology is one of the key industries of the future
👉 Interdisciplinary collaboration drives real innovation
👉 Lower Saxony is a strong location with great potential

With high-level contributions – including Minister Falko Mohrs and Prof. Denise Hilfiker-Kleiner – and valuable insights into companies and research institutions, the day was defined by meaningful exchange and fresh perspectives.

Many thanks to NiedersachsenMetall and all participants for a successful premiere of this event!

In our previous post on oral health, we highlighted why it extends far beyond the mouth and how it impacts the entire body.

Today, on World Oral Health Day, we take it one step further.

Even with good prevention, not every condition can be avoided. When infection reaches the root canal system, treatment becomes necessary to preserve the natural tooth.

However, successful treatment is not the end — it is the beginning of long-term oral health.

A root canal treated tooth remains part of the overall system. Its long-term success depends, among other factors, on:
• good oral hygiene
• stable periodontal conditions
• a well-sealed, definitive restoration
• regular follow-ups

What does this mean in clinical practice?

Modern dentistry follows a clear goal: to preserve natural teeth.

This goes beyond the treatment itself and requires a holistic approach that includes prevention, minimally invasive therapy, and long-term maintenance.

Contemporary endodontic concepts support this approach through effective cleaning, continuous disinfection, and preservation of the natural tooth structure.

Because oral health is not a moment — it is a process.

After the successful and fully booked SAF workshop the day before, the 7th Endodontie Symposium Sachsen took place yesterday in Dresden.

It was a day full of engaging lectures on modern endodontics and tooth preservation, accompanied by a lively industry exhibition that offered plenty of opportunities for professional exchange and discussion.

We were especially pleased about the great interest in the SAF System at our booth, hosted by Roman and Stephan. Many participants and speakers stopped by to exchange ideas about innovative and reliable concepts in root canal treatment.

Endodontic specialists in particular stayed for longer discussions, leading to insightful conversations and exciting debates about the future of root canal treatment.

Thank you to everyone who visited our booth and made these exchanges so valuable!

Today we are in Dresden for the workshop ahead of the Endodontie Symposium Sachsen – and SAF INFINITUM is right in the middle of it.

Thank you for the great interest in our fully booked SAF course and for the engaging discussions during the workshop. It’s great to see how many colleagues are exploring the future of root canal treatment.

Tomorrow the Endodontie Symposium Sachsen begins, where we will be exhibiting with SAF INFINITUM.

A special highlight will be the lecture by Frank Cendelin and Dr. Stephan Gäbler on shaping and cleaning the root canal, featuring exciting clinical insights.

If you are attending the symposium tomorrow:
👉 Stop by our booth, experience the SAF System live, and talk with us about 3D disinfection, continuous irrigation, and minimally invasive preparation.

We look forward to continuing the conversations in Dresden!

On March 20, the world observes World Oral Health Day. We are starting our Month of Oral Health today to highlight the essential role oral health plays in overall well-being.

Why oral health affects the entire body

Oral health is often reduced to a bright smile.
Scientifically, however, it is far more than aesthetics — it is an integral part of general health. Billions of people worldwide are affected by oral diseases. Periodontitis is one of the most common chronic inflammatory conditions — and it does not always remain localized.

🔬 What does research show?

Cardiovascular disease: Chronic gum inflammation is associated with an increased risk of coronary heart disease. Inflammatory processes in the mouth may contribute to systemic inflammation.

Diabetes: Studies indicate that successful periodontal treatment can measurably reduce HbA1c levels. Controlling oral inflammation supports blood glucose control.

Pregnancy: Periodontal inflammation has been linked to a higher risk of preterm birth and low birth weight.

Respiratory disease: In clinical settings, daily toothbrushing significantly reduces the risk of hospital-acquired pneumonia.

🧬 Why does this happen?

The mouth is not an isolated system.
It is a highly complex microbial ecosystem. When bacteria or inflammatory mediators enter the bloodstream, they can influence systemic processes.

🪥 What does this mean in everyday life?

• Brush twice daily with fluoride toothpaste
• Clean interdentally
• Reduce sugar frequency
• Attend regular dental check-ups

Because oral health is prevention for the entire body.

Today, we are introducing the Self-Adjusting File (SAF) – the core of our SAF INFINITUM System 🦷

What sets it apart from rotary files is its unique, compressible nickel-titanium lattice design. The SAF works vertically, gently, and three-dimensionally – while simultaneously enabling continuous irrigation of the canal during preparation.

It adapts to the individual root canal anatomy – not the other way around.

Quality and safety are at the forefront of manufacturing. The SAF is produced in Germany using high-precision laser systems, with production tolerances in the micrometer range (thousandths of a millimeter).

📏 SAF size overview:
• 1.5 mm – for narrow canals (ISO 20–30)
• 2.0 mm – for medium-sized canals (ISO 35–55)
• 3.0 mm – for large canals (> ISO 60)

All variants are available in 21 mm and 25 mm lengths.
SAF 1.5 and SAF 2.0 are also available in 31 mm.

The new SAF 3.0 is a true game changer for very large root canals, immature teeth with open apices, and trauma cases.

Exchange, education, and SAF live in Tel Aviv 🇮🇱🦷 Our Dental Director Johannes visited Tel Aviv, joining our Israeli distributor Osada/GC and participating in a curriculum at the International Dental Studies (IDS) Center.

The curriculum was led by Dr. Michael Solomonov (ד'ר מיכאל סולומונוב, Doctor Michael Solomonov, Доктор Mихаил Cоломонов), an internationally renowned endodontist and Director of the Postgraduate Endodontic Program at Sheba Medical Center. The focus was on canal shaping using the Self-Adjusting File (SAF).

A particularly impressive aspect of the hands-on sessions was the use of accompanying radiographs, which made it clearly visible how SAF adapts individually to a wide range of canal anatomies—an essential component of modern, future-oriented endodontics.

The program was complemented by a lecture from Dr. Alon Amit.

Beyond the curriculum itself, an evening event with experienced SAF users provided space for personal exchange, practical discussions, and valuable networking.

Thank you to Osada/GC, Dr. Solomonov, Dr. Amit, and all participants for the open conversations and the intensive professional dialogue.
