Piezosurgery

Compared to the alternative to piezosurgery – bone processing with drills and cutters – piezosurgery is significantly gentler on the patient. It works precisely, reduces the risk of injury, and accelerates the healing process.

Piezosurgery is characterized by selective, precise cuts limited to the bone for bone removal and bone processing.

Piezosurgery makes it easier to work in areas that are difficult to access. Surrounding structures such as soft tissue, nerves, and blood vessels are spared.

The removal of bone material and bone transplant to compensate for bone loss can be limited to the actual need, thanks to the fine adjustment of the piezo device. This is why piezosurgery is very gentle on the tissue.

The selective and precise piezo method reduces postoperative pain and swelling.

Piezosurgery is very suitable for areas that are difficult to access.

Both the oral surgery dentist and his patients appreciate that piezo surgery works without pressure and the noise that is otherwise common in a dental practice. This is particularly important for anxiety patients.

The intensity of the ultrasound vibrations can be finely adjusted and can, therefore, be adjusted precisely to the density of the bone to be treated. Tissues with a different density, such as the surrounding soft tissue, nerves, and blood vessels, remain unaffected by the ultrasound waves.

Ultrasound surgery is particularly suitable for use:

• During tooth removal
• In oral surgery for surgical tooth removal (wisdom tooth removal)
• In implantology (placement of dental implants)
• When building bone (e.g., during sinus lift/sinus lift procedure)
• In endodontics
• Oral surgery for root tip resections after root canal treatments.

Surgical crown lengthening is used when a tooth up to the gum line has been completely or partially destroyed by caries. In these cases, there is not enough tooth structure to attach a crown with a tight edge to the remaining tooth. In order to gain more surface area for the tooth crown or crowning, the oral surgery dentist lengthens the crown of the remaining tooth by surgically exposing the root portion of the tooth using piezosurgery.

By using piezosurgery, the implant bed or drill hole can be prepared extremely precisely and almost painlessly. A well-prepared implant bed ensures quick and better osseointegration (growth into the bone) of the inserted implant.

When the jawbone breaks down (e.g. as a result of periodontitis), bumps and niches often form in the bone. Osteoplasty, performed using gentle piezosurgery, smoothes the bone and returns the tooth to its natural shape. This makes it easier to care for the affected teeth and makes it more difficult for new bacterial plaque to build up. The osteoplasty method has certainly attracted criticism. Ultimately, periodontitis treatment aims to stop the bone loss associated with periodontitis (also known as periodontal disease). However, osteoplasty removes additional bone. The benefits of the treatment must be weighed up in each individual case.

Piezosurgery enables the minimally invasive and bone-friendly removal of teeth or wisdom teeth. Protecting the jawbone during tooth extraction improves the conditions for later treatment with implants or alternative dentures.

Piezosurgery (ultrasound surgery) is very often used for gentle bone extraction in the context of implantology (for example, alveolar ridge elevation). To do this, the dental implant specialist removes bone chips from another part of the jaw or removes entire blocks of bone, for example, from the hip. He then attaches or transplants the bone replacement materials to the areas affected by bone loss. The separation of the jawbone necessary for this procedure is also called an osteotomy.

The cutting function of piezosurgery is also used to cut “bone windows” for the insertion of bone replacement material. The bone window method is primarily used for building bone in the lateral upper jaw (sinus lift). Sinus floor elevation using piezosurgery is considered a common and safe procedure among implantology specialists and oral surgery dentists.

During a root tip resection/root canal treatment, the dentist removes the tip of the tooth root deep in the bone along with the inflamed tissue. Surgical removal of the root tip is carried out when conventional root canal treatment has not produced the desired result.
