“…Some authors have reported no significant difference in bone repair with use of different drilling speeds (Ribeiro Junior et al 2007). Other investigations have shown a reduction of frictional heat arising from bone drilling when low rotational speed is used (Pirjamalineisiani et al 2015). In contrast, Iyer et al (1997) stated that the rate and quality of healing are better around osteotomies prepared at high speed rather than around osteotomies performed at intermediate or low speeds.…”

“…Next, two drill bits with a diameter of 4 mm and materials of WC and NT were modeled and then the same drill with a diameter of 6 mm and materials of WC and NT modeling 3D. Material characteristics of drill bits and bone are presented in Table 1 [36, 37]. In each of four modes, drill bit models, calcified plaque and artery for meshing and FEM analysis were transferred to ABAQUS software Version 6.14 (Fig.…”

Objective Drilling of calcified plaque (DCP) inside the artery is a method for removing calcified plaques. This study investigated the effect of drill. To validate the maximum temperature calculated by computer simulation, this value was also measured by an experimental on a phantom model. Results Increasing drill bit diameter during drilling would increase the temperature in vascular nerves. In a drill bit with a diameter of 4 mm, the risk of thermal necrosis in vascular nerves of the artery wall decreased by 8.57% by changing the drill from WC to NT. The same value for a drill bit with a diameter of 6 mm was 10.17%. However, the trend of the generated temperature in the vascular nerves did not change significantly with change of the material and diameter of the drill bit. The results showed that for DCP with the least risk of thermal necrosis in vascular nerves and subsequently the lowest risk of restenosis, coagulation and thermal stroke of the patient, the best option is to use a drill bit with a diameter of 4 mm and NT material for drilling.

“…88,167,175,176 Others discovered a significant influence of point angle on bone damage, but the findings are contradictory. For example, the first group unveiled that a larger point angle increases bone temperature 10,21,102,115,123,147,162,167,175,176 and force. 10,21,68,167,174,189 Contrastingly, others found a decrease in heat generation, 5,13,40,133 force, 133 and torque 68,174 with point angle.…”

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.
