“…The results showed death of osteocytes was not only due to temperature elevation, but also because of the drilling force, and both these parameters should be considered to assess the bone damages. This is in good agreement with some previous ndings in the literature [15,34].…”

“…There is also similar contrary view in some other studies [14,26,29]. Despite these contraries, there are also some supports for our results on comparison of temperature elevation in the literature [15,30,31]. As our nite element analyses also implied, the temperature distribution differed in the two drilling methods, which can explain the higher temperature elevation in the ultrasonic drilling.…”

“…In the literature, in recent years, there was a growing interest on studying the e ciency of ultrasonic drilling in bone [6,14,15,[26][27][28][29][30][31]. However, each study had its own drilling parameters that made their outcomes speci c. On the other hand, all of them investigated the application of ultrasonic drilling only in cortical bone.…”

“…In this study, with considering optimum drilling parameters based on previous ndings, we studied both the cortical and cancellous bone. In addition, we not only investigated the drilling force [6,26,28] and the temperature rise [14,15,[27][28][29][30][31], but also assessed their effects: the necrosis and apoptosis of osteocytes through histopathologic evaluation [14,15] in addition to the micro-cracks propagation and mechanical damages with SEM imaging. Finally, employing nite element modeling gave us an insight into the temperature distribution during each drilling method.…”

“…The ultrasonic assembly provided the optional vibration for ultrasonic drilling with frequency of 20 KHz and amplitude of 20 μm. Moreover, three drilling speeds of 500, 1200, and 2000 rpm and two drilling feed-rates of 30 and 60 mm per minute were considered [13][14][15]. Each vertebral bone was drilled with the both drilling methods and similar drilling parameters.…”

Background: A potential method in drilling of bone is ultrasonic-assisted drilling. In addition, during the drilling of bone, which is common in clinical surgeries, excessive heat generation and drilling force may lead to damages in bone tissue, and thus to failure of implants and fixation screws or delay in healing process. The aim of this study was to appraise efficiency of ultrasonic-assisted drilling in comparison to conventional drilling.Methods: In addition to investigating drilling force and temperature elevation, their effects on arising osteonecrosis and micro-cracks were explored in ultrasonic-assisted and conventional drilling through histopathologic assessment and microscopic imaging. In this regard, three drilling speeds and two drilling feed-rates were considered as drilling variables in the in-vitro experiments. Moreover, numerical modeling gave an insight into temperature distribution during drilling process in the both methods and compared three different vibration amplitudes. Results: Although temperature elevations were lower in the conventional drilling, the ultrasonic-assisted drilling had lesser drilling forces. Furthermore, the latter method had smaller osteonecrosis regions, and did not have micro-cracks in cortical bone and destructions in structure of cancellous bone.Conclusions: The ultrasonic-assisted drilling, which caused lesser damages to the bone tissue in both cortical and cancellous bone, was more comparatively advantageous.
