I use this tool for extractions, particularly when I want to conserve bone or the buccal plate. I find it particularly useful for surgical wisdom tooth extractions. The Piezosurgery is like an ultrasonic on steroids with higher vibrations and irrigation by saline solution.
What’s good about it
The Piezosurgery leaves a lot less post-operative pain than the traditional rear vented high-speed. There are no burs spinning at 500,000rpm so there’s less tissue burning. The Piezosurgery is used with a back-and-forth motion, which removes bone gently and allows for much finer work.
The tips on the Piezosugery are very fine, while the angulation of the burs and the way the handpiece is designed allows for easier access to most areas. It comes with a saline irrigation system that stops tissue from overheating. There are some presets that allow for the selection of different parts of the bone—the settings are slightly different for the mandible or the maxilla—and these presets can also be adjusted to suit each patient.
What’s not so good
When performing a wisdom tooth extraction, it takes longer to remove the bone, especially in a dense mandible. However, I still prefer it to a high-speed as I believe the pros outweigh the cons, particularly in regard to post-operative pain and the ability to save bone structure. It’s also a bit technique-sensitive and you need to use a pecking/sweeping motion that is very different to a high-speed.
