A piezotome is a specialized dental instrument that uses ultrasonic technology for precise and controlled cutting of hard tissues, primarily bone, during oral surgery procedures. It is commonly employed in various dental surgeries, including periodontal surgery, implantology, and oral-maxillofacial procedures. Here’s how a piezotome is typically used in dentistry:

• Ultrasonic Cutting: The piezotome generates ultrasonic vibrations that are transmitted to a specially designed cutting tip. These vibrations allow for precise cutting of hard tissues like bone while minimizing trauma to surrounding soft tissues.
• Bone Surgery and Osteotomy: Piezotomes are often used in oral surgeries involving bone, such as in the preparation of the implant site for dental implants or during bone grafting procedures. The device allows for selective and controlled bone removal without damaging nearby structures.
• Sinus Lift Procedures: In sinus lift surgeries, where the sinus membrane is lifted to create space for bone grafting, piezotomes are utilized to make precise cuts in the bone. This ensures a controlled and atraumatic approach, reducing the risk of complications.
• Extraction of Teeth: Piezotomes can be used during tooth extractions, especially when dealing with impacted teeth or teeth with complex root structures. The ultrasonic cutting helps in the controlled removal of bone, facilitating easier and less traumatic extraction.
• Crestal and Lateral Approaches: The versatility of piezotomes allows dentists to choose between crestal and lateral approaches in implantology. The instrument aids in creating precise osteotomies for implant placement, promoting optimal stability and successful integration.
• Periodontal Surgery: Piezotomes are employed in periodontal procedures, such as crown lengthening or pocket reduction surgeries. The controlled cutting ability helps in reshaping bone and achieving desired periodontal outcomes.
• Soft Tissue Preservation: Unlike traditional rotary instruments, piezotomes produce minimal heat during cutting, reducing the risk of tissue damage. This makes them particularly useful in preserving soft tissues, promoting better healing, and minimizing postoperative discomfort.
• Greater Precision and Safety: Piezotomes offer enhanced precision compared to traditional instruments, allowing for intricate and delicate procedures. The controlled cutting also contributes to increased safety during surgery.
• Reduced Vibration and Noise: Piezotomes produce less vibration and noise compared to traditional rotary instruments, providing a more comfortable experience for both the dentist and the patient.
• Postoperative Healing: The use of piezotomes is associated with faster postoperative healing due to reduced trauma to surrounding tissues. Patients may experience less pain, swelling, and discomfort compared to procedures involving traditional instruments.

While piezotomes offer several advantages, they may not replace traditional instruments entirely, and their use depends on the specific requirements of each dental procedure. Dentists often choose the most suitable tools based on the nature of the surgery and individual patient needs.
