“…In case of external irrigation sequences, constant saline cooling of 50 ml/min at room temperature (Ecobag ® click, 0.9% NaCl, 5,000 ml, B. Braun Melsungen AG, Melsungen, Germany) was applied throughout the whole preparation period (drilling start to withdrawing end) using an irrigation tubing set (Irrigation set for machinery—80 mm, 32.F0139, Omnia ® , Fidenza, Italy) and surgical suction was applied at 1.5 cm from preparation site. All osteotomies were performed according to a standard protocol for an atraumatic preparation at 800 rpm (Gaspar et al., 2013; Koopaie et al., 2019; Oliveira et al., 2012; Scarano et al., 2020; Strbac et al., 2015; Strbac, Giannis, et al., 2014; Strbac, Unger, et al., 2014).…”

Objectives The aim of this study was to evaluate thermal effects of ceramic and metal implant drills during implant site preparation using a standardised bovine model. Material and Methods A total of 320 automated intermittent osteotomies of 10‐ and 16‐mm drilling depths were performed using zirconium dioxide‐based and stainless steel drills. Various drill diameters (2.0/ 2.2, 2.8, 3.5, 4.2 mm ∅) and different cooling methods (without/ with external saline irrigation) were investigated at room temperature (21 ± 1°C). Temperature changes were recorded in real time using two custom‐built multichannel thermoprobes in 1‐ and 2‐mm distance to the osteotomy site. For comparisons, a linear mixed model was estimated. Results Comparing thermal effects, significantly lower temperatures could be detected with steel‐based drills in various drill diameters, regardless of drilling depth or irrigation method. Recorded temperatures for metal drills of all diameters and drilling depths using external irrigation were below the defined critical temperature threshold of 47°C, whereas ceramic drills of smaller diameters reached or exceeded the harmful temperature threshold at 16‐mm drilling depths, regardless of whether irrigation was applied or not. The results of this study suggest that the highest temperature changes were not found at the deepest point of the osteotomy site but were observed at subcortical and deeper layers of bone, depending on drill material, drill diameter, drilling depth and irrigation method. Conclusions This standardised investigation revealed drill material and geometry to have a substantial impact on heat generation, as well as external irrigation, drilling depth and drill diameter.

“…39,53,91 Notwithstanding these controversies, to counter the threat of drill bit wear, improvements over the existing surgical drill bit design is necessitated. For example, wear-resistant material (e.g., zirconia 23,24,45,109 and HSS 87 ) could be adopted in designing a new drill bit. Also, the thermal cycling method could be applied to the surgical drill bit to improve the performance, durability, and longevity of materials.…”

As drilling generates substantial bone thermomechanical damage due to inappropriate cutting tool selection, researchers have proposed various approaches to mitigate this problem. Among these, improving the drill bit design is one of the most feasible and economical solutions. The theory and applications in drill design have been progressing, and research has been published in various fields. However, pieces of information on drill design are dispersed, and no comprehensive review paper focusing on this topic. Systemizing this information is crucial and, therefore, the impetus of this review. Here, we review not only the state-of-the-art in drill bit designs-advances in surgical drill bit design-but also the influences of each drill bit geometries on bone damage. Also, this work provides future directions for this topic and guidelines for designing an improved surgical drill bit. The information in this paper would be useful as a onestop document for clinicians, engineers, and researchers who require information related to the tool design in bone drilling surgery.

“…However, Kim et al showed that lower drilling speeds do not increase the heat transferred to bone tissues despite the increasing working time [18]. The wear of dental implant drills have been previously analyzed by means of finite element analysis (FEA) [19] and scanning electron microscopic (SEM) and energy-dispersive x-ray spectroscopic examinations [20]; however, none of these measurement procedures allows an accurate analysis of surface and volumetric wear experienced by the dental implant drill after clinical use, because FEA analysis performs a digital simulation and the SEM examination allows only a superficial analysis, preventing the volumetric changes measurement. However, geomorphometric technique allows an accurate measurement of both surface and volumetric changes between the non-use and continued use dental implant drill.…”

The aim of this comparative study is to analyze the influence of drilling technique on the radiographic, thermographic, and geomorphometric effects of dental implant drills and osteotomy site preparations. One hundred and twenty osteotomy site preparations were performed on sixty epoxy resin samples using three unused dental implant drill systems and four drilling techniques performed with a random distribution into the following study groups: Group A: drilling technique performed at 800 rpm with irrigation (n = 30); Group B: drilling technique performed at 45 rpm without irrigation (n = 30); Group C: drilling technique performed at 45 rpm with irrigation (n = 30); and Group D: drilling technique performed at 800 rpm without irrigation (n = 30). The osteotomy site preparation morphologies performed by the 4.1 mm diameter dental implant drills from each study group were analyzed and compared using a cone beam computed tomography (CBCT) scan. The termographic effects generated by the 4.1 mm diameter dental implant drills from each study group were registered using a termographic digital camera and the unused and 4.1 mm diameter dental implant drills that were used 30 times from each study group were exposed to a micro computed tomography (micro-CT) analysis to obtain a Standard Tessellation Language (STL) digital files that determined the wear comparison by geomorphometry. Statistically significant differences were observed between the thermographic and radiographic results of the study groups (p < 0.001). The effect of cooling significatively reduced the heat generation during osteotomy site preparation during high-speed drilling; furthermore, osteotomy site preparation was not affected by the wear of the dental implant drills after 30 uses, regardless of the drilling technique.
