What is dental piezotome surgery?
“It’s a bone surgery technique that appeared in dentistry at the end of the 1990s. It works based on a ultrasonic phenomenon. An electric current deforms ceramic rings, which sends this movement to the tips in contact with the bone. The tips will then vibrate according to a determined frequency and amplitude. This results in a much more precise surgery, as incisions are very fine, and more respectful to tissue compared to the traditional scissors, saws and bone cutters.”
Are there other advantages?
“For dentists, tactile sensitivity is better: there is no need to push or force, which the patient will also appreciate. It is also safer: there is no impact on soft tissue. For example, there is no risk to injuring the nerve in the lower jaw.
In practical exercises, we can remove the shell of an uncooked egg without breaking the tiny underlying membrane! Visibility is better due to a spray which cleans the wound during use. There is also an antibacterial effect due to the cavitation phenomenon.”
When should it be used?
“We use it for dental extractions; the bone is eliminated minimally, even around complex anatomy roots, including impacted wisdom teeth, and cysts. Implant placement is made easier, as well as sinus lifts. But the main new thing is that we can use it to accelerate orthodontics treatments in adults for whom it is necessary to mobilise teeth in the bone. Small incisions in the gum are all that’s needed.”
