“…A study [31] has analyzed wear based on scanning electron microscope analysis, revealing that repeated drill use deteriorates the physical and mechanical surface properties of the surgical drill. This mean thermal increase occurred in all types of materials [9,10,26,32]. The 10 sterilization cycles could be influenced by thermal variations, as evidenced by another study with the use of electron microscopy [33].…”

“…The present study overcame the limitations of the thermal measurement method with infrared thermography and the of drilling medium with the use of standardized synthetic blocks [21][22][23][24][25][26][27][28]. The thermal conductive discrepancy between the tested materials could cause different heat concentrations in the friction zone [22] and distinct dissipation of the heat through the drill [10,24,29]. However, these factors do not appear to be sufficiently influential to result in statistically significant differences in overall mean thermal variation between the tested materials.…”

“…Other authors have compared others types of materials and have reported no statistically significant changes in mean thermal variation during drilling [25][26][27]. Hochscheidt et al [10] reported a higher mean temperature with diamond-like carbon-coated drills than with stainless steel drills-though the difference failed to reach statistical significance. The mentioned study drilled bovine ribs with a different cortical thickness of between 2-3 mm, and the temperature was monitored with a thermocouple, which may affect the measurements [21][22][23][24][25][26][27][28].…”

“…The most widely studied material is stainless steel [6]. However, ceramics [9] and coated stainless steel such as diamond-like carbon-coated [10] or direct diamond-coated drills [11] have also been studied. The thermal changes associated to diamond-like carbon-coated drills have been investigated in a study [10] that found no statistically significant differences with respect to stainless steel drills.…”

Objective: An in vitro study was made to compare mean thermal variation according to the material, design and wear of the surgical drills used during dental implant site preparation. Material and methods: Three study groups (stainless steel drills with straight blades; diamond-like carbon-coated drills with straight blades; and diamond-like carbon-coated drills with twisted blades) were tested to compare material, design and wear of the surgical drill in terms of overall mean values (complete sequence of drills) and specific mean values (each drill separately). The groups comprised four drills: initial, pilot, progressive and final drill. Implant site configuration was performed through an intermittent and gradual drilling technique without irrigation at 800 rpm in standardized synthetic blocks. Maximum axial loading of two kilograms was controlled by an automatic press. Each surgical drill was submitted to 50 drillings and was sterilized every five uses. A thermographic camera analyzed the mean thermal changes. The software-controlled automatic press kept systematic drilling, axial loading and operational speed constant without any human intervention. Student’s t-test, ANOVA and multiple linear regression models were performed. The level of significance was 5% (p = 0.05). Results: The overall mean comparison between the stainless steel and diamond-like carbon-coated materials showed no statistically significant differences (p > 0.05), though specific mean comparison showed statistically significant differences between the drills of the different groups (p < 0.05). The twisted blades exhibited less overall and specific mean thermal variation than straight blades for the progressive and final drills (p < 0.01). In addition, the initial and pilot drills showed a greater mean thermal change than the progressive and final drills. The mean thermal variation was seen to increase during the 50 drillings. Conclusions: Within the limitations of this study, it can be concluded that the drill material did not significantly influence the overall mean thermal variation except for the pilot drill. The drill design affected overall and specific mean thermal variation since the twisted blades heated less than the straight blades. The initial and pilot drills increased the specific mean thermal variation with respect to the progressive and final drills. In addition, all drills in each group produced a gradual increase in mean temperature during the 50 drillings.

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.

Thermal Variation During Osteotomy With Different Dental Implant Drills

Abstract: After 50 uses, the greatest ΔT occurred in EG and the ∅3.0-mm drill exhibited the highest mean and peak temperatures. Temperatures were influenced by irrigation, number of uses, depth, drill diameter, geometry, and material; however, mean values were within physiological limits.
