“…A serra pneumática para corte de osso, além dos danos térmicos, também criou múltiplas microfissuras na superfície óssea cortada; esses danos foram associados à fricção mecânica da serra, provocando um retardo no processo de reparo ósseo. Outro estudo 19 mostrou que o preparo cirúrgico para implantes utilizando ultrassom consumiu mais tempo e alcançou temperaturas mais altas ao osso do que a cirurgia convencional. Além disso, foi observado que o aumento de carga não teve nenhum efeito sobre o aumento da temperatura.…”

“…Speed, pressure, irrigation and bur shape have been identified as some of the most important factors influencing temperatures rising (3). The impact of pressure and irrigation has been also investigated with respect to implant site preparation with piezoelectric instruments (26,27).…”

“…Although the irrigation was not a specific issue of this investigation, it was proven to play an important role in reducing temperatures (22,27). However, the irrigation efficacy in limiting temperature elevation is evident in tests with warmed bone samples (37° C) (Fig.…”

“…Furthermore, a thicker cortical implies a wider contact tip surface, a longer contact time and an overall energy consumption. However, it is still an issue of debate whether higher temperatures arise in cortical rather than in cancellous bone (24). The higher compactness of the cortical bone, requiring higher energies and more time for preparation, was pointed out in explanation of different thermal alteration reported in cortical and cancellous bone (26).…”

SummaryBackground. Overheating during implant site preparation negatively affects the osseointegration process as well the final outcome of implant rehabilitations. Piezoelectric techniques seem to provide to a gentle implant preparation although few scientific reports have investigated the heat generation and its underlying factors. Purpose. To investigate, through a proper methodological approach, the main factors influencing temperature rise during piezoelectric implant site preparation.

“…In another study previously carried out on beagles, Bengazi et al 22 also found that osseointegration of implants is possible if the sites are prepared using conventional drill cutters with copious irrigation or by means of piezoelectric surgery. Results of previously conducted in vitro 29 and ex vivo 30 studies also evidenced that conventional osteotomy and osteotomy by means of piezoelectric surgery are equally safe methods for preparing sites for dental implants.…”

ObjectiveTo carry out a histological comparison, at different postoperative periods, of bone tissue repair after implant site preparations on the tibia of pigs using both a piezoelectric device and rotary instruments. MethodsSurgical procedures were performed on the tibia of four pigs. Five perforations were made in the left tibia using star shaped piezosurgery tips (Piezosonic Driller ® ) and five perforations in the right tibia using carbon coated rotary drills (DSP Biomedical ® ). The pigs were then sacrificed at 2, 7, 14, and 28 days. The tibiae were removed and the tissues were prepared for histological processing and analysis under a light microscope. ResultsThe histological analyses showed similar results at 2 days and both groups presented inflammatory infiltrate. At 7 days, the drill system produces a regular surface preparation and the process of bone repair was greater when compared with the piezoelectric device. At 14 days the presence of new bone formation was more intense with the drill system. However, at 28 days both systems showed similar results, with the presence of an organized, newly formed bone tissue. ConclusionIt was possible to conclude that both implant site preparations, using the piezoelectric device and rotatory instruments, resulted in similar bone neoformation at 28 days.Indexing terms: Bone regeneration.

RESUMO ObjetivoComparar os aspectos histomorfológicos do tecido ósseo após osteotomias realizadas em tíbias de suínos com sistema piezoelétrico e instrumentos rotatórios em diferentes tempos pós-operatórios. MétodosProcedimentos cirúrgicos foram realizados em tíbias de quatro suínos, sendo que cada animal recebeu cinco perfurações na tíbia esquerda utilizando sistema piezoelétrico com pontas em forma de estrela (Piezosonic Driller ® ) e cinco perfurações na tíbia direita utilizando fresas rotatórias com revestimento de carbono(DSP Biomedical ® ). Os animais foram sacrificados nos tempos pós-operatórios de 2, 7, 14 e 28 dias. As tíbias foram removidas e o material foi processado para exame histológico em microscopia de luz. ResultadosAo exame histológico, observou-se após 2 dias, achados semelhantes para os 2 grupos, revelando a presença de tecido compatível com um coágulo junto a um infiltrado inflamatório no leito osteotomizado. Aos sete dias, os preparos realizados com fresas se mostraram mais regulares e houve sinais de maior neoformação óssea próxima ao tecido ósseo remanescente quando comparados ao sistema piezoelétrico. No grupo de 14 dias ficou evidente maior neoformação óssea ao longo de todo leito cirúrgico no grupo de fresas, enquanto o sistema piezoelétrico apresentou neoformação óssea dispersa, porém ao final de 28 dias, a análise morfológica tecidual foi semelhante em ambos os grupos, com a presença de trabeculado ósseo reorganizado. ConclusãoPode-se concluir que os achados da análise morfológica revelaram que tanto o sistema piezoelétrico como as fresas na preparação de nichos para implantes promoveram neoformação óssea...

Heat production during different ultrasonic and conventional osteotomy preparations for dental implants

Abstract: Ultrasonic implant site preparation is more time consuming and generates higher bone temperatures than conventional drilling. However, with the levels of irrigation, ultrasonic implant site preparation can be an equally safe method.
