This method provides an immense advantage over traditional surgical instruments such as drills and saws for many surgical procedures as it enables the selective treatment of tissue. Bone tissue can be cut with almost no pressure on the adjoining soft tissue, even if it comes into contact with the instruments. This means the adjacent blood vessels are protected as much as possible. Reduced vascular injuries mean less post-operative swelling, faster healing and a minimised risk of wound infection.
Using this technique, the risk of injury to nerves or their displacement or decompression can be significantly reduced as well. In implant surgery, Piezosurgery offers maxillary sinus floor augmentation (also known as “sinus lift”), a non-traumatic alternative to conventional drilling technology which significantly reduces the likelihood of injury to the maxillary sinus mucosa.
As life expectancy increases, bone deficits due to periodontitis or invasive processes can become an increased obstacle to the desire for fixed dental prosthesis. By means of Piezosurgery, you can get gentle bone transplants which can then replace the lost bone permanently.
In addition, Piezosurgery is applied daily in our practice within the treatment of infected root tips. In cases where the inflammation has already penetrated the jaw bone or when a conventional (“anterograde”) root canal filling by a dentist is not possible because of dental condition, the root tip must be surgically removed. It is crucial for the prognosis of the tooth to make both the root reduction and bone resection as gentle as possible. In ideal cases, it results in a wound area of just 3 millimetres in diameter! If it is evident upon inspection of the root tip that the root canal is not closed sufficiently and there is a threat of the re-ignition of the root tips, the channel should be prepared and sealed from the operated side (known as “retrograde root canal treatment”). In order to be able to perform this in a micro surgical approach, special angled instruments are required. These may not be rotating, but controlled by ultrasonic vibration. Piezosurgery applies in this case once again.
