The use of ultrasonic vibrations for the cutting of bone was first introduced two decades ago. Piezoelectric surgery is a minimally invasive technique that lessens the risk of damage to surrounding soft tissues and important structures such as nerves, vessels, and mucosa. It also reduces damage to osteocytes and permits good survival of bony cells during harvesting of bone. Piezoelectric surgery was first used by oral and maxillofacial surgeons for osteotomies, but recently some specific applications in neurosurgery and orthopaedics have been proposed. We review the different applications of piezoelectric surgery.

Monitoring cardiac rhythm is crucial for diagnosis of heart failure. However, the deficient sensitivity of polyvinylidene fluoride (PVDF) sensors impede their application in monitoring of cardiac rhythm due to the limited piezoelectricity. Here, doping of CoFeO and aligning fibers were jointly adopted to enhance the piezoelectricity of PVDF, attributed to the transformation of α-PVDF to β-PVDF from 51.

Introduction: This is a double clinical trial conducted to study the patient satisfaction and comfort during and after surgical removal of impacted mandibular 3rd molar using Piezo electric tips.
Material And Methods: Two groups of 25 each [14 (56 %) males and 11 (44 %) females] and [18 (72 % males and 07 (28 %) females] represented the Rotary and Piezo groups respectively with bilateral impactions. one side of the patient is operated by piezo and the other side by rotary instrument after a gap of 2-3 week between the procedures.
Ultrasound-Mediated Piezoelectric Microneedles Regulating Macrophage Polarization and Remodeling Pathological Microenvironment for Lymphedema Improvement.

Lymphedema, a severe and complex inflammatory disease caused by lymphatic system insufficiency and impeded lymphatic drainage that causes an enormous physical and psychological burden on patients and may even lead to death, has long been a challenging issue in the medical field. Clinically, conventional approaches including surgical treatment and conservative treatment have been employed for lymphedema therapy, but their curative effect is still unsatisfactory because of high operational difficulty, high cost, and long-term reliance. In this study, a novel kind of piezoelectric microneedle driven by ultrasound (US) is proposed to regulate macrophage polarization and remodel the pathological inflammatory microenvironment in a noninvasive manner, thereby promoting lymphatic regeneration and improving lymphedema.

Chitosan (CHT) is a known piezoelectric biomacromolecule; however, its usage is limited due to rapid degradation in an aqueous system. Herein, we prepared CHT film via a solvent casting method and cross-linked in an alkaline solution. Sodium hydroxide facilitated deprotonation, leading to increased intramolecular hydrogen bonding and mechanical properties.

: Third molar (wisdom tooth) extraction is one of the most common surgical procedures in oral and maxillofacial surgery. Traditional rotary instruments and burs have long been the standard tools for this procedure. However, recent advancements in surgical techniques, such as piezoelectric surgery, have gained popularity due to their purported advantages in terms of precision, safety, and postoperative outcomes.
