background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

Piezosurgery, or the use of piezoelectric devices, is being applied increasingly in oral and maxillofacial surgery. The main advantages of this technique are precise and selective cuttings, the avoidance of thermal damage, and the preservation of soft-tissue structures. Through the application of piezoelectric surgery, implant-site preparation, bone grafting, sinus-floor elevation, edentulous r...

BACKGROUND Most dental implants are positioned using a drilling surgery technique. However, dentistry recently experienced the implementation of piezoelectric surgery. This technique was introduced to overcome some of the limitations involving rotating instruments in bone surgery. This study used biomolecular and histologic analyses to compare the osseointegration of porous implants positioned ...

Statement: Osteotomies are well-established procedures in oral and maxillofacial surgery for either corrective measures or for gaining access to subjacent hard and soft tissues. Yet surgical reconstruction of bony defects can often be very challenging as thin and fragile bony structures are especially prone to fracture due to bulky cutting tips or massive application of pressure by conventional...

Abstract Introduction Piezoelectric device or piezosurgery device was originally developed for the atraumatic cutting of bone by way of ultrasonic vibrations and as an alternative to the mechanical and electrical instruments that are used in conventional oral surgery. Over the past two decades, an increasing amount of literature has shown that piezoelectric devices are innovative tools and that...

The aim of this work has been to evaluate the use of Piezosurgery in the different otological surgical techniques. Piezoelectric bone surgery, also known simply as Piezosurgery, is a new technique for osteotomy and osteoplasty. The equipment consists of two piezoelectric handpieces and two inserts that are connected to a main unit. This unit supplies power and has holders for the handpiece and ...

  Background and purpose: Conventionally, rotary devices were used for bone surgery. Recently, new techniques have been proposed such as piezosurgery. The prevalence of impacted teeth which should be removed is high. There are different techniques for bone removal that are associated with specific complications. This study compared the postoperative complications of impacted third molar extrac...

in this paper, design and construction of a tactile sensor for measuring contact-force is presented. mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. by considering a specific point in the circuit and recording the changes of its voltage, ma...
