“A small brush head and a double bend for a wide range of application options”

Kriens, September 2018 – For people with implants, fixed dentures and braces, excellent oral health is essential. The new CS 708 toothbrush makes this easy, and can reach even particularly confined and hard-to-access areas. The reason for its extra-small head and double bend is explained by Dr. Hugo Roberto Lewgoy in the following interview.

“A small brush head and a double bend for a wide range of application options”


Dr. Hugo Roberto Lewgoy, you and Professor. Dr. Kirsten Warrer of the University Aarhus, Denmark, cooperated in the development of the new toothbrush for Curaprox. How did this corporation come about?

When working with my patients, I realised that they were missing an important oral hygiene tool: a toothbrush to clean fixed dentures and implants. An effective and atraumatic brush that doesn’t cause any injury. Full hybrid dentures that are retained by screws threaded into the implant abutments, for example, are extremely hard to clean. They are screwed onto multiple implants and so are securely anchored into the jaw. As bacteria collects particularly quickly underneath these prostheses, good hygiene is essential. This can only be achieved if the toothbrush bristles can reach underneath the dentures, which is barely possible when using a conventional brush. That’s why I suggested to Curaden AG that we work together to develop a brush that can do just that. I was joined in my quest by Kirsten Warrer, a specialist in periodontology who has been involved in the development of other products such as the Implant Saver.

How does developing a toothbrush work?

I started off by considering what properties the toothbrush would need in order to fulfil its purpose. One thing was for sure: it needed to have a very small brush head. A double bend, with one bend on the handle and one on the head, would help to achieve the perfect cleaning angle. Our experience showed us that our patients are experiencing the same difficulties despite having very different implants and physical attributes. So we wanted to design a toothbrush to help all of our patients.

Where did you go from there?

The technicians at Curaden AG then got to work and developed a range of different prototypes. We tested out various textures and bristle lengths before finding a prototype that we were all impressed with.

In spring 2018, the ”CS 708 implant | ortho” came on the market. A special brush – for which purpose exactly?

In the initial phase, we were working on a toothbrush for implantology patients, although we later established that the CS 708 could also be very helpful in the field of orthodontics, mainly for the cleaning of fixed lingual orthodontic appliances. The CS 708 can reach even particularly hard-to-access areas thanks to its small head as well as the fact that it can be bent as required.

Does the CS 708 replace the CS Single single-tuft brush?

No – the CS Single is still essential for cleaning the sulcus. The CS 708 does look very similar, just with a longer handle and a smaller head, and is suitable for implants, fixed dentures, wires and brackets.

Curaprox toothbrushes all have a high amount of bristles, a rather small angled head and often an octagonal handle. What about the CS 708?

The octagonal handle that we are familiar with from the classic Curaprox toothbrushes is really eye-catching. But even more important than the design is its function; this shape means that the toothbrush can be applied to the teeth at a 45-degree angle, otherwise known as the Bass technique. With the CS 708, the handle is flatter like the CS Single, and has a non-slip design so that the toothbrush sits securely in the hand. This is essential in order to ensure effective and safe cleaning of fixed dentures. The brush head of the CS 708 is small but has seven brush tufts. At 0.12 mm, the Curen® filaments are particularly fine, and the bristles, head and handle make it possible to clean even underneath dentures and implants.

How does one clean correctly with the CS 708?

Apply the CS 708 to one side of the implant or dentures. Move the brush up and down and forwards and backwards using small circular motions so that the head moves, and the filaments can reach underneath the appliances. Guide the CS 708 closely along the appliance from one side to the other using small, gentle circular motions.

Oral health is on the right track, even periodontitis is reversed, as the "Fifth German Oral Health Study (DMS V) "* shows. What do you recommend for even better oral health? More fluoride? Better nutrition? More interdental cleaning? Train children even better?

We now know for certain that oral diseases and in particular cavities and gum diseases can be completely prevented by the mechanical break-down of the biofilm. Periodontitis can also be improved with good oral hygiene. Nevertheless, there is no treatment that eliminates the need for correct oral hygiene. The CS 708, for example, helps to prevent mucositis and peri-implantitis. It’s the following Curaprox philosophy that really appeals to me: Curaprox offers people the right tools to keep their teeth healthy. It’s a well-known fact that our oral health is closely related to our overall health. Good oral hygiene can prevent or stabilise systemic diseases. Curaprox is serious about looking after our health, and follows its objective of offering people a better state of well-being, and one important step on this journey is perfect oral health. I am convinced that interdental brushes are really important in achieving this goal, and believe that everyone should use these interdental brushes, even children. After all, habits learned at an early age are often continued throughout our entire life.

So more interdental brushes?

Yes, and not just for patients with gum diseases; for everyone. When you use interdental brushes as part of your daily routine, oral diseases disappear. You could even say that your life improves as a result.

At the same time as the CS 708, Curaprox launched a new toothpaste: in brightly coloured tubes and six extraordinary flavours, all containing glucose oxidase, hydroxyapatite, fluoride and herbs. What do you think of the BE YOU? Have you tried it yet?

When it comes to brushing teeth, I basically see toothpaste not as a protagonist but rather as playing a secondary role, providing support, reinforcement and helping to motivate people. As we’ve already discussed, the mechanical destruction of the oral biofilm is crucial, and this process requires the use of the wide range of available toothbrushes, interdental brushes and tongue scrapers, as well as the new CS 708. Toothpaste ensures fresh breath and makes brushing your teeth a pleasant experience. Yes, I’ve tried BE YOU...

Your favourite?

...“Pure Happiness” - the name says it all. But I’m even more impressed by the formula: it contains only substances that strengthen the teeth and gums. This toothpaste does not contain any ingredients that subject the gums to any unnecessary irritation. BE YOU is a low-abrasion product. For us dental professionals, it’s really important that we empower and motivate our patients to take control of their own oral hygiene. Colourful toothbrushes, and now the matching toothpastes too, are really helpful here, as they keep patients motivated which in turn improves their oral health.

Thank you for the interview, Dr. Lewgoy.
