State-of-the-art ultrasound technology in bone surgery

Current developments focus on minimally invasive procedures with less post-operative pain for the patient and a faster healing time. Piezo technology has increasingly been finding its way into oral and maxillofacial surgery (OMFS) and implantology for more than a decade. Maximum precision in surgical use and gentler treatment for the patient are just some of the advantages of this cutting-edge drive technology. With the new Piezomed, W&H can use state-of-the-art ultrasound technology for even the most demanding tasks in bone surgery, providing the surgeon with optimal support in his daily work.

“Our product development has a clear aim: to consistently fulfil the many different needs of the patients and also to satisfy the users’ requirements. The new Piezomed minimises the invasiveness of surgical treatments. Safe working thanks to automatic instrument detection and unique instrument design takes on a completely new meaning for the user,” said Andreas Lette, Strategic W&H Product Manager and Head of Product Innovation.

A new dimension in bone surgery

The new surgical instrument from W&H employs state-of-the-art ultrasound technology. High-frequency microvibrations enable high-precision incisions while the so-called cavitation effect ensures an almost blood-free surgical site and an excellent view of the treatment area.

In addition to these clear benefits of cutting-edge piezo technology, W&H offers maximum safety during operation with its patented automatic instrument detection. Piezomed detects the instrument during insertion and sets the correct power class automatically. This significantly lowers the risk of overloading the instruments.

Equipped for any task

W&H offers a selected range of 24 intelligently created working instruments to provide optimum cover for the wide variety of tasks dealt with by surgeons. “For example, the bone saws have a specially developed tooth design which enables bone block harvesting with low bone loss. We also offer a special saw which boasts extremely high cutting performance.

Many of the surgical instruments developed by W&H are an absolute world first in the global dental sector. Our developments are patented to protect our unique expertise,” explained the Strategic Product Manager. The instruments have another significant advantage in their efficient cooling concept.

The spray exits near the instrument’s work area thus protecting the instrument from thermomechanical material stress. The user benefits from even safer processing of the operating field. Piezomed supports the surgeon’s individual way of working with three different operating modes: “Power”, “Basic” and “Smooth”. The operating modes store a variety of performance characteristics. Equipped with a multi-functional foot control, the surgical device ensures optimum freedom for the users hands.

First reports from users

The new Piezomed enables W&H to satisfy its users’ expectations perfectly. “Many of our customers are already making excellent use of Piezomed in the practices and whilst carrying out clinical work. It is essential for us to obtain feedback on a medical and professional level to enable us to verify that our development aims are being implemented consistently,” explained Andreas Lette.

Initial reactions from Dr. med. dent. Mario Kirste MSc, a specialist in implantology and oral surgery from Frankfurt (Oder, Germany) and Dr. Ulrich Fürst, a dentist specialising in oral surgery from Attnang-Puchheim (Austria) are testament to the great relevance of Piezomed in everyday surgery,

“Piezomed heralds the start of a new age in the use of piezo technology in dental surgery. The automatic instrument detection function is a particular advantage of the new Piezomed. This not only facilitates operation, but also increases application safety.”

Dr. Ulrich Fürst

“Incredible – the new Piezomed cuts through bone like butter. The innovative, very thin special saw with coolant which exits at the operating point leaves nothing to be desired in terms of cutting speed, cooling of the saw blade and the hard tissue to be treated.”
