“…This result should not be clinically relevant because the temperature peaks lasted less than 1 s, until the preparation site was made over 5 s, and this is not enough to cause irreversible changes in bone healing. This is supported by previous study focused on healing [ 31 ]. All these facts together make different drilling protocols necessary with the help of modern bone cutting devices.…”

“…Furthermore, more active osteogenesis was reported in sites prepared with piezosurgery rather than conventional osteotomy with standard steel bur [ 2 ]. The results of one of the previous studies [ 31 ], which analyzed healing of bone tissue treated with piezosurgery, Er:YAG laser in contact and non-contact modes using laser profilometry, showed the best result for non-contact digitally controlled mode of laser. Healing after non-contact digitally controlled laser was slightly slower in the first week because of temperature changes, but equal or even faster after three weeks.…”

The bone healing process following osteotomy may vary according to the type of surgical instrumentation. The aim of the present in vivo study was to determine thermal changes of the bone tissue following osteotomies performed by Er:YAG laser ablation in contact and non-contact modes, piezoelectric surgery, and surgical drill using an infrared thermographic camera. For each measurement, the temperature before the osteotomy-baseline (Tbase) and the maximal temperature measured during osteotomy (Tmax) were determined. Mean temperature (ΔT) values were calculated for each osteotomy technique. The significance of the difference of the registered temperature between groups was assessed by the ANOVA test for repeated measures. Mean baseline temperature (Tbase) was 27.9 ± 0.3 °C for contact Er:YAG laser, 29.9 ± 0.3 °C for non-contact Er:YAG laser, 29.4 ± 0.3 °C for piezosurgery, and 28.3 ± 0.3 °C for surgical drill. Mean maximum temperature (Tmax) was 29.9 ± 0.5 °C (ΔT = 1.9 ± 0.3 °C) for contact Er:YAG laser, 79.1 ± 4.6 °C (ΔT = 49.1 ± 4.4 °C) for non-contact Er:YAG laser, 29.1 ± 0.2 °C (ΔT = −0.2 ± 0.3 °C) for piezosurgery, and 27.3 ± 0.4 °C (ΔT = −0.9 ± 0.4 °C) for surgical drill. Statistically significant temperature changes were observed for the non-contact laser. The results of the study showed beneficial effects of the osteotomy performed by the Er:YAG laser used in the contact mode of working as well as for piezosurgery, reducing the potential overheating of the bone tissue as determined by means of infrared thermography.

“…Four published studies [89][90][91][92] suggest Er:YAG-lasers in non-contact application with a computerized scanninghandpiece to provide faster bone-healing in vivo than piezotome-instrumentation, but was equal when Er:YAG-laser was used in contact-mode. The evidence value of these studies is low with EV: 0,5 ( Table 1).…”

Background: New tools for bone-cutting were introduced to oral and maxillofacial surgery in the last decade, such as lasers and piezotomes. Purpose: to evaluate most recent evidence, when surgical procedures performed with drills or burs are compared with laser-and/or piezotome-surgical procedures in experimental and clinical studies and to assess possible advantages of their use in daily practice. Methods: a systematic search of various medical databases with specifi c keywords was performed, excluding studies published before 2006 for their possible invalidity by technological progress. Systematic reviews were assigned to Group 1, experimental studies ex vivo to Group 2, in vivo to Group 3 and clinical studies to Group 4. All studies in each of the groups 2-4 were appraised regarding their evidence, starting with a value of 0 for no evidence of advantages of lasers and/or piezotomes compared to rotary instruments, 1 for moderate evidence with verifi ed clinical impact and 2 for strong evidence and signifi cant clinical impact and statistically processed for their Evidence Value (EV) in each group and their Overall mean Evidence Value (OmEV). Results: 129 studies were fi nally included for evaluation. Two systematic reviews concluded lack of evidence for lasers to be advantageous over burs/drills. Nine reviews for piezotomes reveal strong evidence piezotome-surgery to signifi cantly reduce morbidity and to enhance soft-tissue preservation. Comparative experimental and clinical studies of burs/drills vs lasers revealed a low EV in Group 2 (EV:0,8), Group 3 (EV:0,5) and Group 4 (EV:0,5) with an OmEV of 0,6. Comparative studies burs/drills vs piezotomes resulted in a signifi cant EV in all groups (

Introdução: A piezoeletricidade surgiu em meados do século XIX, o piezo ultrassônico consiste na utilização de um aparelho ultrassônico, capaz de cortar tecido ósseo mineralizado, sem lesionar o tecido mole sendo essa uma de suas principais vantagens quando comparado às técnicas convencionais com brocas, serras e instrumentais. Objetivo: Este estudo tem como objetivo, realizar uma revisão de literatura acerca das diversas utilizações do piezoeletricidade na odontologia. Materiais e Metódos: Para a elaboração desse artigo foi realizada uma revisão narrativa da literatura, utilizando as bases de dados: PUBMED/ MEDLINE, Google acadêmico, Scielo, Revodonto, LILACS, BBO e Portal CAPES. Foram selecionados artigos que abordassem os assuntos cirurgia com ultrassom, piezocirúrgico, técnicas cirúrgicas alternativas e aparelhos cirúrgicos de vibração. Discussão: De acordo com a teoria dos irmãos Curie o efeito piezoelétrico acontece através do uso de tipos específicos de cerâmicas e cristais como o quartzo, os quais sofrem deformações quando uma corrente elétrica passa através deles, resultando em oscilações de frequência ultrassônica e quando aplica-se sobre uma superfície estas vibrações mecânicas geram uma ruptura na coesão molecular provocam cavitações nesta superfície. Conclusão: O piezocirúrgico ultrassônico demonstra ser um dispositivo seguro e eficaz para a realização de procedimentos cirúrgicos na odontologia, devido a proteção aos tecidos moles, melhor hemostasia, diminuição do ruído e vibração, diminuição do estresse e medo do paciente, minimização de dano a estruturas nobres como feixes vásculo nervoso.
