“…Contrary to rotary instruments and oscillating saws, the piezoelectric tips do not require pressure on bone to be effective and, therefore, thermal injuries and bone microfractures are reduced ( 6 , 9 , 15 , 16 ). It is generally accepted that cutting with piezoelectric instruments takes longer than with rotary burs or oscillating saws, especially when the surgeon is learning this technology ( 6 , 10 , 15 , 17 , 18 ). Spinelli et al showed in a recent maxillofacial study in humans that the whole surgical procedure took 35% longer with a piezoelectric bone unit compared with an oscillating saw ( 10 ).…”

“…As seen before, piezoelectric bone surgery is usually considered to be slower than osteotomy with a bur or with an oscillating saw ( 6 , 10 , 15 , 18 ). Nevertheless, constant improvement of this new technology by manufacturers has led to more efficient instruments, which with the learning curve by the surgeon, minimizes this problem ( 17 , 18 , 32 ).…”

“…Ultrasonic bone cutting instruments were first proposed by Vang in 1955; however, they did not gain popularity until the early 21st century. This coincided with the need for more precise osteotomies as the emphasis in maxillofacial surgery extended to involve cortical bone graft collection and surgery of sinus in preparation for dental implant placement ( 6 , 7 ). The technology is based on inverse piezoelectric activity: alternative current applied to piezoactive ceramic disks generates high-frequency vibratory energy ( 8 ).…”

Piezoelectric bone surgery is a recent and innovative technology, permitting a selective cut of mineralized tissue while sparing soft tissue. Similar to a dental scaler, a high frequency vibration, in the range of 25–35 kHz, is transmitted to a metallic tip. However, the power of the piezosurgical instrument is three to six times higher than that of a dental scaler. The major advantages of this technology include high precision, a design that increases ease of curvilinear osteotomy, less trauma to soft tissue, preservation of neurological and vascular structures, reduced hemorrhage, minimal thermal damage to the bone, as well as overall improvement of healing. The handpiece of the instrument is equipped with a sterile irrigation system and light-emitting diode (LED) light, which improves visibility and overall safety. Piezoelectric surgery is particularly useful when performing delicate bone procedures such as periodontal or endodontic surgery. It is also indicated when performing more invasive bone surgery such as maxillectomy, mandibulectomy, and condylectomy, where preservation of neurovascular structures is important. Piezoelectric instruments are different from rotary instrumentation or oscillating saws, they require light pressure with constant motion of the tip. Training is required to master the technique.

“…For USSs, a bolt-clamped-Langevin transducer, a type of UT, is used for high power applications, such as ultrasound surgical systems [ 20 ]. The UT used for cutting soft tissues in surgical operation have been widely developed around 1990s, however, currently developed UT is still difficult to dissect large size soft tissues until now [ 21 ]. Therefore, improved vibration amplitude of UT is helpful to dissect and coagulate the soft tissues.…”

A wireless ultrasound surgical system (WUSS) with battery modules requires efficient power consumption with appropriate cutting effects during surgical operations. Effective cutting performances of the ultrasound transducer (UT) should be produced for ultrasound surgical knives for effective hemostasis performance and efficient dissection time. Therefore, we implemented a custom-made UT with piezoelectric material and re-poling process, which is applied to enhance the battery power consumption and output amplitude performances of the WUSS. After the re-poling process of the UT, the quality factor increased from 1231.1 to 2418 to minimize the unwanted heat generation. To support this UT, we also developed a custom-made generator with a transformer and developed 2nd harmonic termination circuit, control microcontroller with an advanced reduced instruction set computer machine (ARM) controller, and battery management system modules to produce effective WUSS performances. The generator with a matching circuit in the WUSS showed a peak-to-peak output voltage and current amplitude of 166 V and 1.12 A, respectively, at the resonant frequency. The performance with non-contact optical vibrators was also measured. In the experimental data, the developed WUSS reduced power consumption by 3.6% and increased the amplitude by 20% compared to those of the commercial WUSS. Therefore, the improved WUSS performances could be beneficial for hemostatic performance and dissection time during surgical operation because of the developed UT with a piezoelectric material and re-poling process.
