Piezosonic Extraction Technique: A Gentle Approach

St Lawrence Dentistry offers Piezo Sonic Technology which can make dental extractions much more gentle.

When we talk about dental extractions there are many goals that Dr. Hawryluk keeps in mind.

These are:

  • Keeping the patient comfortable
  • Remain conservative and achieve little or no bone removal around the tooth to be removed
  • Achieving a successful and desired outcome
  • Lay the foundations for a possible dental implant
  • Minimise trauma
  • Be able to observe clinical success in the months ahead

When are extracting teeth Dr. Hawryluk is always looking to create the conditions which will allow for the best healing. In many cases, when removing teeth, Dr. Hawryluk is creating a bed for something else to go in later such as a dental implant. One of the problems which can be encountered in traditional extraction methods is the breaking of the ‘buccal plate’ which is the socket bone next to the cheek. It is imperative to keep this in tact to preserve as much bone as possible for the successful placement of a potential future dental implant. St. Lawrence Dentistry also wants to make sure the way we take out a tooth is minimally invasive so when the patient goes home after the tooth removal they are comfortable.


When Guilin Woodpecker Medical Instruments put their new piezo sonic unit in Dr. Hawryluk’s hand he could not be more excited. This has meant an extraordinary advance in dental patient care. The piezo unit has a dynamic power setting and it can regulate its power itself. This new technology can effortlessly get the job done while at the same time avoid collateral damage to soft tissue such as the gums, sinus membranes, and nerves.


The first step of the piezo extraction technique is local anesthesia. We do not underestimate the importance of good anesthesia and Dr. Hawryluk will take the time to make sure the patient is very numb and comfortable. Before removing a tooth Dr. Hawryluk will go around the tooth with a ‘molt’ instrument which loosens the soft tissue around the tooth. Then the piezo-sonic unit is used and gentle pressure is applied down in the ‘periodontal ligament’ space which encompasses the tooth. The Woodpecker Piezo unit has different settings of power and water supply based on the procedure we are doing. Dr. Hawryluk will alternate between different tips and will place the tip in the ligament holding the tooth to the bone to enlarge it, thus making the extractions far easier. Next Dr. Hawryluk will use a forcep and remove the tooth while preserving the ‘buccal plate’ of bone. No one wants a dental extraction, but if is indicated, piezo technology can get it done with a method which preserves your bone and is far gentler.


The best thing about the Piezo sonic dental extractions is the great post operative comfort patients have. In many cases, when doing piezo assisted extractions, these patients have little or no complains about discomfort and therefore do not need much analgesic medication. Dr. Hawryluk finds this really important in terms of the relationship of the dentist and patient This is especially great for patients who are medically compromised as we may be limited on how we can pharmacologically manage post extraction pain encountered frequently by the older legacy extraction methods.

The piezo extraction technique is far more conservative than traditional extraction techniques which use carbide burs to contour away bone to access broken tooth bits. In many cases modern piezosonic extractions can avoid a ‘flap’ when doing an extraction (pushing back the gum to access the tooth bits). Teeth come out more cleanly and the bone socket tends to have a healthy fresh look when teeth are removed. The piezo unit will loosen the tooth from the ligament and it will accomplish much of the extraction process in a gentle fashion.

If the dentist uses a carbide bur instead of a piezo tip around a tooth to facilitate removal, the bur can vibrate, jump, and risks tearing into the surrounding mucosa tissue. This can cause damage which can affect the soft tissue, floor of mouth, and a host of other areas.

In many causes a tooth can be removed in one piece as opposed to breaking it into pieces. There is less leaning on other teeth to provide a fulcrum to remove the tooth in question. This means there is far less incidence of collateral damage to the adjacent teeth. Unlike conventional ‘surgical extractions’, the piezo technique does not remove bone, instead it simply loosens the ligament holding the tooth to the bone.

The Piezo extraction technique unit is backed by revolutionary technology and has given us the ability to offer our patients a much more comfortable experience with excellent post procedure outcomes.
