EWF: Extraction Without Forceps
The atraumatic dental extraction technique that allows for tooth removal without pain, forceps, or sutures.
Creator and developer of the EWF technique
We have improved dental extraction with the EWF technique
Dr. Fabio Cozzolino has perfected the EWF (Extraction Without Forceps) technique, an innovative method that has revolutionized the approach to dental extractions.
With over 30 years of clinical experience, Dr. Cozzolino specializes in periodontology, implantology, and complex extractions. He has published numerous scientific studies and is a speaker at national and international congresses.
The EWF technique has been described in the scientific journal Zerodonto and is cited on Wikipedia as a reference for atraumatic dental extractions.
Why choose the EWF technique?
Extraction in seconds
Most extractions are completed in 7-30 seconds thanks to the efficiency of the levers.
80% Fracture reduction
Clinical experience shows a dramatic reduction in fractures compared to forceps.
Less patient stress
The patient perceives less force and movement during the extraction process.
Faster recovery
Less trauma means less swelling, pain, and significantly reduced healing times.
Fewer sutures
In most cases, stitches are not required, reducing the risk of alveolitis by 90%.
Scientific technique
Published in medical journals as a reference for atraumatic extractions.
What is the EWF technique?
EWF stands for Extraction Without Forceps. Instead of using traditional forceps to pull the tooth, this technique utilizes dental levers inserted between the tooth and the alveolar bone.
Rapid extraction
With the EWF technique, wisdom tooth extraction often takes only a few seconds. Some procedures are completed in just 7 seconds.
Pain-free
Local anesthesia completely eliminates pain during the procedure. The patient experiences minimal stress thanks to the precision of the technique.
Fracture reduction
Levers apply force at a single point, allowing the tooth to follow the path of least resistance, reducing root fracture risk by 80%.
Better post-op
Less trauma translates to faster recovery, less swelling, reduced post-operative pain, and less need for stitches.
Higher precision
The technique leverages physical principles to multiply the applied force, making the extraction more efficient and controlled.
Superior safety
Combined with sonic surgery, the EWF technique drastically reduces the risk of injury to nerves and blood vessels.

The science behind the EWF technique
The Lever Principle
Law of Moments: A small force applied at a great distance from the fulcrum generates significant force on the tooth.
Mechanical Advantage: The longer the lever arm, the less force is required to extract the tooth.
Single point of application
The lever applies force at a single point between the tooth and alveolar bone, allowing the tooth to follow its natural path of least resistance.
Controlled rotary movement
The movement combines rotation along the lever’s axis with apical and lateral thrust, creating a gradual and atraumatic luxation.
Stress distribution
Stress on the root is uniformly distributed, drastically reducing the risk of fracture even with curved or thin roots.
Anatomical respect
The tooth moves according to its natural anatomy and the shape of the socket, without forcing it in non-physiological directions.
The three classes of levers in EWF
First-class lever
The fulcrum is located between the effort and the tooth. Example: initial luxation phase with the fulcrum on the alveolar bone.
Second-class lever
The tooth (resistance) is between the fulcrum and the effort. Example: during the elevation of the tooth.
Third-class lever
The effort is between the fulcrum and the tooth. Used in specific maneuvers depending on the anatomy.
The biomechanical situation is dynamic: during extraction, the lever can act as different classes depending on the phase and positioning.
How does the EWF technique work?
The method is based on the physical principles of levers to amplify force and make the extraction atraumatic
- Local anesthesia – Administered to ensure maximum patient comfort throughout the procedure.
- Anatomical evaluation – A periodontal probe is used to assess the depth and anatomy of the tooth.
- Lever insertion – The lever is positioned in the periodontal space between the tooth and the alveolar bone.
- Controlled application – Controlled force is applied in apical and lateral directions, rotating the lever along its axis.
- Luxation and extraction – The tooth is first luxated, then extracted following the direction of least resistance.
- Post-operative management – Whenever possible, sutures are avoided to reduce the risk of complications.
EWF vs. Traditional Forceps
The fundamental difference between the two techniques lies in how force is applied to the tooth
Traditional Forceps
Forceps apply force on two opposite points, forcing the tooth into a predefined direction.
The tooth is forced to move in the direction chosen by the operator, which may not be the path of least resistance.
Root stress is high, especially if the root is thin or has sharp curvatures.
Extraction generally requires more time and repeated maneuvers.
The patient clearly feels the applied force and the movements of the tooth.
Suturing is often necessary, increasing the risk of post-operative complications.
EWF Technique
The lever applies force at a single point, allowing the tooth to follow its natural direction.
The tooth rotates and moves in the direction of least resistance, like a train on tracks.
The root undergoes much less stress, drastically reducing the risk of breakage.
Many extractions are completed in 7-30 seconds thanks to force amplification.
The patient perceives significantly less force and movement during the process.
In most cases, no sutures are needed, reducing complications by 90%.
The train on tracks analogy
With levers (EWF): It’s like pushing a toy train on a track; you apply force at one point and it follows the rails in the direction of least resistance.
With forceps: It’s like grabbing the train with two fingers and pulling it off the tracks; you force it where you want, risking a derailment (fracture).
Frequently Asked Questions
The EWF (Extraction Without Forceps) technique, developed by Dr. Fabio Cozzolino, involves tooth extraction using only specialized levers. Unlike forceps, which “grip” the tooth and impose a forced direction, levers allow the tooth to follow its line of least resistance, reducing the risk of root fractures by up to 90%.
Absolutely. For impacted teeth or those in critical positions (close to the alveolar nerve), we use sonic surgery and operating microscopes. This combination allows us to separate the tooth into small fragments with millimeter precision, avoiding nerve contact and minimizing bone removal. This approach is much more conservative and safer than traditional surgery.
No. Thanks to the use of levers, the applied force is not perceived by the patient as traumatic pressure. Many patients report not feeling any “pulling” or “pushing” during the procedure, which is often completed in seconds, making the experience much more comfortable than traditional techniques.
At Studio Cozzolino, we use sonic handpieces that vibrate instead of rotate. This is crucial in complex cases: sonic tips cut the bone but do not damage soft tissues (such as the alveolar nerve or the tongue) in case of accidental contact, ensuring extreme safety and a post-operative recovery without excessive swelling.
Due to the extreme gentleness of the atraumatic EWF technique, stitches are often not necessary. This significantly speeds up healing, reduces the risk of alveolitis, and ensures an immediate return to daily life without the discomfort of surgical threads in the mouth.
For the first 24 hours, we recommend avoiding hot foods, smoking, alcohol, and intense physical exertion. A soft and cold diet is preferred. Thanks to the speed of the EWF procedure, post-operative pain is minimal and generally manageable with common analgesics, often taken only as a precaution immediately after the appointment.
Sonic surgery: maximum safety
Sonic surgery uses micrometric vibrations instead of rotary burs. This allows for millimetric precision in cutting bone and teeth without damaging soft tissues, nerves, or blood vessels, even in case of accidental contact.
Selective cutting
Sonic tips work only on hard tissues (bone and tooth) while completely respecting soft tissues like nerves and vessels.
Maximum precision
Allows for safe approach to delicate structures like the alveolar nerve or the maxillary sinus membrane.
Zero overheating
Sonic technology prevents tissue overheating, reducing post-operative swelling and pain.
