“…Multiple unique features of the PI have been recognized that confer important advantages to the PI compared with motorized reciprocating tools. The PI does not cut nonmineralized tissues including dura mater when it touches them . Thus, when applied to neurosurgical, craniofacial and orbital surgery, it is possible to perform “blind” osteotomy with fewer precautions necessary for the dura mater , facial nerve, or globe .…”

“…16 One such instrument, the piezoelectric device, is an ultrasonic tool designed for safe and effective osteotomy or osteoplasty compared with traditional reciprocating instruments. [16][17][18][19][20] Piezoelectric devices use low frequency ultrasonic waves (25)(26)(27)(28)(29)(30) that are created by the piezoelectric effect. 21 The applied power can be modulated between 2.8 and 16 W producing linear micro-vibrations between 60 and 210 mm and the machine is programmable in accordance with the density of the bone being cut.…”

“…The main advantages of piezosurgery include soft tissue protection, optimal visibility in the surgical field, decreased blood loss, less vibration and noise, increased comfort for the patient and protection of tooth structures. 20 Several authors have reported that piezoelectric osteotomy reduces the post-operative facial swelling and trismus, [15][16][17][21][22][23] although a slightly longer surgery time is required. 17,23 Our present results also indicated that piezosurgery required a slight lengthening in terms of surgical duration, compared to the use of conventional rotary instruments, but this difference was limited in surgeons with greater experience.…”

This is an author version of the contribution published on:Questa è la versione dell 'autore dell'opera: J Oral Maxillofac Surg. 2014 Oct;72(10):1890-7. doi: 10.1016/j.joms.2014 AbstractPurpose: The surgical removal of mandibular third molars is frequently accompanied by significant post-surgical sequelae, and different protocols have been described to improve such adverse events. The aim of this study was to investigate the performance of piezosurgery compared with traditional rotating instruments during mandibular third molar removal. Methods:A single-centre, randomized, split-mouth study was performed using a consecutive series of unrelated healthy Caucasian patients, attending the Oral Surgery Unit of the University of Turin, for surgical removal of bilateral mandibular third molar teeth. Each patient was treated, at the same appointment, using bur removal on one side of the mandible and a piezoelectric device on the contralateral side. The primary outcomes reported were postoperative pain, objective orofacial swelling and the duration of surgical time; secondary outcomes were sex, age and possible adverse events. Anova or paired t-test were used as appropriate to test any significant differences at baseline according to each treatment subgroups and categorical variables were analysed by χ2 test.Results: The study sample consisted of 100 otherwise healthy patients. The mean pain evaluation reported by patients who underwent surgery with the piezosurgery was significantly lower than that experienced after bur (conventional) removal, reaching a statistical difference after 4 days (P=0.043). The clinical value of orofacial swelling at 7th day, normalized to baseline, was lower in the piezosurgery group (P<0.005).The average time of surgery was significantly lower in the bur than piezosurgery group (P<0.05).Three patients having bur removal experienced short-term complications (two dry sockets and one temporary paraesthesia): both totally resolved by 4 weeks. Conclusions:To date, this prospective investigation is the largest reported split-mouth study on piezosurgery for lower third molar tooth removal, also comparing surgeons with different 3 degrees of experience. It is evident that using a piezoelectric device can enhance the patient experience and reduce post-operative pain and swelling.

“…Pavlíková et al 19 , hicieron una amplia revisión de los procedimientos realizados en cirugía maxilofacial con sistema piezoeléctrico mostrando experiencias en buena parte de los procedimientos conocidos. Los resultados son favorables y describen ventajas del uso de este sistema como: disminución de lesiones de tejidos blandos como nervios, membrana sinusal y dura madre debido principalmente a la mayor refrigeración y al corte "selectivo" que realiza el sistema; también la pérdida sanguínea disminuye principalmente debido a la irrigación constante del suero y a que la cavitación genera desplazamiento de fluidos lo que también permite una adecuada visibilidad; la osteotomía puede ser completa sin necesidad de la aplicación de cincel en las etapas finales de la osteotomía y en definitiva, ventajas comparativas a los sistemas tradicionales.…”

“…Pavlíková et al 19 , reportaron una investigación realizada en modelos de ratas donde se ejecutaron osteotomías con broca convencional en un lado del parietal y osteotomías circulares con ultrasonido en lado inverso. Se concluyó que en el lado convencional existía significativo daño cerebral al ser comparados con los efectos del ultrasonido, demostrando la utilidad que podría prestar este instrumento en cirugías complejas del cráneo y órbita.…”

Craneomaxillofacial osteotomy with ultrasonic system. Treatment option and initial experienceUltrasonic system has revolutionized the surgical technique in maxillofacial surgery; they work with a cavitation phenomenon being able to perform osteotomies without damaging on nervous, muscular and vascular tissues or any soft tissue. This condition provides security to the variety of surgery with bone cut close to vessel or important nerves how the condilectomy technique of the mandibular condyle, mandibular osteotomy close to the alveolar nerve, orbital osteotomy and others. This paper present contemporary information about the use in craniofacial surgery and the initial experience of the authors using this system. We conclude that the osteotomy with ultrasonic system can be optimized the surgery with slight increase of surgical time decreasing bleeding and risk to the injury to the soft tissie; is possible beleave that this kind of instrument can be used in any surgery with bone cut necessity.Key words: Ultrasonic, osteotomy, maxillofacial surgery. ResumenLos sistemas ultrasónicos han revolucionado la técnica quirúrgica en cirugía maxilofacial; son sistemas que funcionan con el fenómeno de cavitación siendo capaces de realizar osteotomías sin lesionar los tejidos nerviosos, musculares, vasculares o tejidos blandos en general; esta condición entrega seguridad a la variedad de cirugías que actúan cortando tejido óseo en áreas próximas a vasos y nervios importantes, como en la técnica de condilectomía del cóndilo mandibular, osteotomía mandibular próximo al nervio alveolar inferior, osteotomías orbitarias, entre otras.
