“…Cavitation elicits also an anti-bacterial action, by fragmenting the cellular membranes of bacteria (Arrojo et al, 2008) and, furthermore, a cleansing action on the osteotomic surface ensues.In this study, the presence of bone debris was found to be strictly related to the thickness of the osteotomic line: the cleansing efficacy of the cavitational effect appeared efficient in wider osteotomies. In fact, Variosurg 3, Sonicflex Bone, K-Bisonic and Piezotome 2, which showed the cleanest osteotomic surfaces, showed at the same time the widest osteotomic tracks.Both sonic instruments showed almost no signs of thermal injuries on the osteotomised surfaces: in accordance with data in the literature describing sonic osteotomy as safe in terms of heat generation(Heinemann et al, 2012;Rashad et al, 2015). Signs of thermal injuries at various levels were observed in samples from ultrasonic osteotomes: among them Piezotome 2, Piezosurgery Touch and Variosurg 3 were found to be the safest devices.…”

The most common adverse effect after bone cutting is a thermal damage. The aim of our study was to evaluate the bone temperature rise during an alveolar ridge splitting, rating the time needed to perform this procedure and the time to raise the temperature of a bone by 10°C, as well as to evaluate the bone carbonization occurrence. The research included 60 mandibles (n = 60) of adult pigs, divided into 4 groups (n = 15). Two vertical and one horizontal cut have been done in an alveolar ridge using Er:YAG laser with set power of 200 mJ (G1), 400 mJ (G2), piezosurgery unit (G3), and a saw (G4). The temperature was measured by K-type thermocouple. The highest temperature gradient was noted for piezosurgery on the buccal and lingual side of mandible. The temperature rises on the bone surface along with the increase of laser power. The lower time needed to perform ridge splitting was measured for a saw, piezosurgery, and Er:YAG laser with power of 400 mJ and 200 mJ, respectively. The temperature rise measured on the bone over 10°C and bone carbonization occurrence was not reported in all study groups. Piezosurgery, Er:YAG laser (200 mJ and 400 mJ), and surgical saw are useful and safe tools in ridge splitting surgery.

“…Rashad et al 19 observed, after a total of 360 osteotomies events between the ultrasonic system and the rotatory system, the ultrasonic system reached critical temperatures over 47°C in 5 osteotomies. In contrast, in our study the maximum temperature was 34.8°C.…”

Aim: To compare in vitro the site preparation of dental implant using a rotatory system and an ultrasonic system by evaluating the variability of temperature, time and primary stability that is provided by the different sequences of dental implant drills and tips. Materials and methods: Sixteen osteotomies were performed with different sequences of drills (Initial, Titamax 2.0, 2/3 and 3.0) for the rotatory group (RG) and tips (IM1S, IM2P, IM2/3, IM3P) for the ultrasonic group (UG) on bovine cortical-cancellous bone samples. Micro-CT images were acquired to assess bone microarchitecture and bone mineral density of each sample to guarantee similar bone conditions. For the RG, the osteotomies were performed with a dental implant contra-angle handpiece at 800 rpm and 50 N/cm maximum torque using an implant micromotor. For the UG, the osteotomies were performed using a Piezosurgery3 system with the respective tip. The temperature was measured and four implants 3.75 9 11 Titamax were installed in each group to measure the final torque. Results: For the RG, the following mean values were found: 22.87 s, 24.2°C superficial temperature, 27.6°C perforation temperature and 32.30 N/cm torque. The UG values were 72.9 s, 26.6°C superficial temperature, 32.1°C perforation temperature and 22.60 N/cm torque. Conclusions: Rotatory and ultrasonic systems are effective methods for implant site preparation with satisfactory outcomes. For corticalcancellous preparation sites, the drills of the RG were related to lower temperatures and less time for osteotomy. Thus, the use of rotatory systems is preferred due to the heat differential generated during the dental implant sites preparation. Clinical relevanceScientific rationale for study Osteotomy techniques are superior due to greater precision when performed with ultrasonic systems; however, data on temperature and surgical times related to such systems are still controversial in the literature when compared to conventional rotatory systems. Principal findingsRotatory system was related to lower temperatures and less time for osteotomy during dental implant sites preparation.Oral Surgery 13 (2020) 108--116.
