Accelerating treatment plans with less invasive procedures

Meeting with Violaine Tissier-Tureau, General Manager France, during the EuroPerio Congress.


Acteon is one of the world leaders, if not the world leader in ultrasonic instruments. What are the advantages of using ultrasound (should this read ultrasonic?) - based techniques in the periodontal maintenance of teeth?

Violaine Tissier-Tureau : Acteon's ultrasonic expert states, “thanks to the patented electronics, combined with tips designed in exclusive alloys of variable hardness, we are able to respect the different surfaces being treated. The wide range of tips is predominantly made of stainless steel but we have plastic tips available for the treatment of ceramics, or Grade 4 titanium tips for implant maintenance.


You have a very wide range of dental tips, is it likely that manual curettes will become redundant?

V. T.-T. : No, but the benefits of ultrasound has been widely published in recent years. The effectiveness (about 30,000 vibrations per second) and safety near soft tissues are two of the most well-known benefits but also the technique requires less pressure than manual curettes, resulting in a much lower risk of causing damage to enamel and restorations. Many tips have been specially developed for the treatment and maintenance of periodontitis, our most popular are the H3 and H4. The TK range has been specifically designed for periodontal maintenance, these probe-shaped graduated tips fit gently into the periodontal pocket to disrupt the biofi lm and assess the depth.


Your range of tips seems to be well developed for many clinical applications, how many do you have?

V. T.-T. : We have more than 80 tips for a variety of treatments including prophylaxis, periodontics, orthograde and retrograde endodontics, canal irrigation and prosthetic finishing. These tips connect to our Newtron® P5XS tabletop devices as well as to Acteon handpieces integrated into our partners’ chairs. A very large range of the treatments performed by general practitioners and specialists can be done with our equipment. We have also developed a surgical range that is thriving.


Your company has done a lot of research on the use of ultrasound in surgery with the development of the dental piezotome. Did you off er a session on this during Europerio, if so, what was the topic?

V. T.-T. :Yes, many surgical procedures can now be performed ultrasonically, from the most commonly performed; a dental extraction, to the most advanced; accelerated orthodontic surgery, this is what we wanted to demonstrate during Europerio. To give a bit of history, we launched the Piezotome® range at the ADF in 2005. It was the very beginning of ultrasound in surgery with the main benefit being, the ability to cut hard tissue without damaging soft tissues. Since then, there have been many developments both technically and clinically. The power has been increased and the clinical benefits stemming from reducing post-operative pain to greater treatment acceptance are now a reality. The latest addition to this surgical line is the Piezotome cube. It is a “smart” device that increases its power by +30% when it detects resistance, and decreases by -10% when in contact with more fragile tissues. This system makes it possible to be even more powerful, yet safer. Ultrasonic extraction is a very concrete example; piezotome limits the use of force and the well-known luxation movement that can lead to bone damage. Ultrasonic extraction can be performed without raising a flap, by sliding the extremely fine tips into the periodontal space, parallel to the root. The latest studies show that pain, swelling and the need for painkillers is reduced by 50%. Pre-implant surgeries can also be performed such as crestal or lateral sinus lifts, crestal expansions or corticotomies.


Are these the techniques that were presented at your symposium here in Amsterdam?

V. T.-T. : Yes, the first session brought together Dr Abdah from Cambridge and Dr Nares from UIC Chicago and covered bone preservation during extractions, thanks to Piezotome® Cube and the very fine periotome tips. The different clinical cases presented, really demonstrated the benefits for the practitioner and the patient, of using ultrasound for extractions. The preservation of the bone completely avoids the need for alveolectomy and strongly favours immediate implant placement. The second session was led by two Orthodontists, Professor Lambert and Dr Charavet. They both work at Liège University Hospital, and their research focuses on the Piezocision™ technique, to accelerate orthodontic treatment in a way that is reproducible, reliable and minimally invasive. The majority of interest in this technique is in the collaboration between implantologists and orthodontists. Studies show the treatment plan is 43% faster than a conventional technique and bone densification is generated by the use of Piezotome. Many other discoveries on the benefits of ultrasound in the dental and medical field are expected in the coming years. Acteon remains strongly involved in these major discoveries that will benefit the practitioner, simplify treatment plans and enhance the lives of patients as a result of increasingly minimally invasive interventions.
