Wisdom tooth extraction is one of the most common surgical interventions in dental practice. Despite the apparent routine nature of the procedure, operations on impacted and displaced third molars are still associated with a number of potential complications, including postoperative pain, swelling, limited mouth opening, soft tissue damage, and delayed healing. This is why the search for methods that can make surgical intervention less traumatic and more predictable remains one of the important directions in the development of modern dental surgery.
In recent years, piezosurgery — a technology that uses ultrasonic microvibrations for selective impact on bone tissue — has been attracting increasing attention from specialists. Initially, the technique became widespread in implantology and bone grafting operations, but today its capabilities are also being actively studied in the field of wisdom tooth extraction. Many specialists consider piezosurgery to be one of the most promising tools for reducing surgical trauma and increasing patient comfort.
The growing interest in this technology is due not only to the technical advantages of the equipment but also to a change in approaches to dental care in general. Modern surgery is increasingly focused on minimal invasiveness, tissue preservation, and accelerating patient rehabilitation, which makes piezosurgery particularly relevant in the context of the development of digital and high‑tech dentistry.
For many decades, the main tools for performing osteotomy during the removal of impacted third molars remained surgical burs, rotary handpieces, chisels, and hammers. These methods have proven their effectiveness and continue to be widely used throughout the world. However, mechanical impact on bone tissue is inevitably accompanied by a certain degree of trauma to surrounding structures.
Cases are considered especially complex when the tooth is located in close proximity to the inferior alveolar nerve or other anatomically significant structures. In such situations, the surgeon faces the need for the most accurate removal of bone tissue without the risk of damaging surrounding soft tissues.
It was this need that became one of the reasons for the emergence of piezosurgical technologies. Unlike traditional rotating instruments, ultrasonic tips make it possible to selectively affect mineralized tissue, practically without damaging nerves, blood vessels, and mucous membranes. This operating principle opens up new possibilities for performing more delicate surgical interventions.
The basis of the technology is the use of high‑frequency ultrasonic vibrations. Special tips perform microscopic movements, which allow precise cutting of bone tissue with minimal mechanical impact on surrounding structures. Thanks to the physical properties of soft tissues, ultrasonic energy practically does not damage blood vessels, nerves, and mucous membranes.
This mechanism of action differs significantly from traditional methods based on high‑speed bur rotation. When using piezosurgery, the surgeon gains the ability to work more controllably, gradually removing the necessary volumes of bone while maintaining maximum precision of movements. This technology takes on particular importance in cases of complex wisdom tooth extraction, when surgical access is limited and the proximity of important anatomical structures requires increased caution.
One of the main advantages of piezosurgery is the high precision of osteotomy. The ultrasonic tool allows for thin and controlled bone cuts without excessive tissue removal. This is especially important when working in anatomically complex areas of the jaw. When removing impacted wisdom teeth, the surgeon is often forced to form a bone window to gain access to the crown or roots of the tooth. The more carefully this stage is performed, the higher the likelihood of preserving the surrounding bone tissue and the better the conditions for subsequent healing. Furthermore, the high precision of the intervention reduces the likelihood of accidental damage to adjacent teeth and other anatomical structures. This is especially important in the treatment of young patients, when it is crucial to preserve the maximum volume of healthy tissue.
One of the most discussed advantages of piezosurgery is its impact on the postoperative period. Recent studies show that patients after third molar extraction using ultrasonic technologies often report less intense pain, less pronounced swelling, and faster recovery of masticatory function compared to traditional methods. Meta‑analyses and systematic reviews confirm the trend toward a reduction in the severity of postoperative complications, including trismus — limited mouth opening, which is one of the most common complaints after wisdom tooth extraction.
It is assumed that such results are associated with a more gentle effect on tissues during surgery. Minimization of mechanical trauma contributes to a reduction in the inflammatory response and improved conditions for tissue regeneration. For patients, this means more comfortable recovery and the ability to return to their normal lifestyle more quickly after surgery.
In modern dentistry, increasing attention is paid to issues of tissue preservation. Even during tooth extraction, an important task is to preserve the maximum volume of bone tissue to maintain the anatomy of the jaw and possible subsequent prosthetics or implantation.
Piezosurgical instruments allow osteotomy to be performed more delicately and with less bone tissue loss compared to some traditional techniques. This creates favorable conditions for healing and can be important for the long‑term condition of the alveolar process. This aspect becomes particularly relevant in cases where the patient may need implant treatment in the future. Preserving bone architecture facilitates subsequent restorative procedures and contributes to achieving more predictable outcomes.
Despite its numerous advantages, piezosurgery is not a universal solution for all clinical situations. One of the main disadvantages of the technology is considered to be the increase in the duration of the operation. Most studies note that performing osteotomy with ultrasonic instruments requires more time compared to using traditional rotary systems.
For an experienced surgeon, the difference may be relatively small, but when performing a large number of operations, this factor takes on a certain significance. Another limitation remains the high cost of the equipment. Piezosurgical devices and specialized tips require significant financial investment, which may limit the spread of the technology in some clinics. Furthermore, successful use of the method requires additional training and the acquisition of practical experience. Working with ultrasonic instruments differs from the usual technique of using burs, so specialists need to adapt to new principles of surgical intervention.
The spread of ultrasonic technologies reflects a broader trend in the development of modern medicine and dentistry. Today, treatment methods aimed at maximizing tissue preservation and reducing the invasiveness of interventions are becoming increasingly important. Minimally invasive surgery not only improves clinical outcomes but also increases patient satisfaction with treatment. People are increasingly paying attention not only to the final result of the procedure but also to comfort during treatment and the speed of recovery after it. In this context, piezosurgery is becoming part of a general strategy for the development of modern dental care, focused on a combination of high efficiency, safety, and biological gentleness.
Experts note that the potential of piezosurgery is far from exhausted. Manufacturers continue to improve equipment, developing more efficient tips and expanding the range of clinical indications for the use of ultrasonic technologies. At the same time, the volume of scientific research aimed at studying the effect of piezosurgery on tissue regeneration processes, the quality of bone healing, and long‑term treatment results is growing. Current literature reviews indicate the high promise of the method, although researchers emphasize the need for further multicenter studies to definitively confirm a number of the technology’s advantages.
It is likely that in the coming years, piezosurgery will be increasingly integrated into standard protocols of surgical dentistry, especially when performing complex interventions that require high precision and maximum tissue preservation.
The development of piezosurgery demonstrates how significantly approaches to dental surgery are changing in the 21st century. If earlier the main criterion for the effectiveness of an operation was considered solely the successful removal of the tooth, today issues of tissue preservation, minimization of complications, and improving the patient’s quality of life in the postoperative period come to the fore. The use of ultrasonic technologies in wisdom tooth extraction makes it possible to implement the principles of modern minimally invasive surgery, providing a high level of precision and a more gentle attitude toward surrounding tissues. Although the technique requires additional time and financial costs, its advantages in terms of postoperative comfort and biological safety are making it increasingly in demand in clinical practice.
The relevance of this topic will only increase as dental technologies continue to develop and patient expectations rise. Piezosurgery is already becoming an important element of a new treatment philosophy, at the center of which is not only a successful surgical outcome but also the maximum preservation of the patient’s health and well‑being at every stage of dental care delivery.
