“…It turned out that the simplified technique did not influence bone formation. What is more, studies conducted by El-Kholey and Elkomy [34] showed that a simplified drilling technique generates as much heat as the conventional one. To prove their hypothesis they used 80 implants with 2 different diameters placed in bovine ribs.…”

The aim of this experimental study was to verify thermal diffusion differences, by measuring the maximum temperature achieved with different drill shapes. Synthetic bone blocks of type I density made from solid rigid polyurethane (PUR) foam were used to perform the drilling procedures. The experiment was conducted at three different rotation speeds: 800, 3000 and 5000 rpm. Conical drills (with and without an internal cooling hole) were compared with horizontal drills and disc drills. The temperature during drilling for implant bed preparation was estimated with the use of thermocouples and an infrared (IR) camera. The temperature during drilling with disc cutters for lateral basal implants did not exceed 33 ∘C and the temperature decreased in proportion to higher drill speed. The results indicate that the tested design is safe and will not cause bone overheating.

“…For example, increasing drill bit diameter increases the chisel edge length, drill flute area, and web thickness. Many studies have reported an increase in drilling outputs-normal stress, 73 drilling force, 19,97,164,174,196 torque, 85,164,174 osteonecrosis regions, 6,7 and bone temperature 2,4,6, 16,42,43,51,59,70,81,85,91,97,98,101,105,115,123,130,159,176,180,181,199 -with the increase of drill diameter. Researchers have applied two-step drill bit (a drill bit with smaller drill tip for initial bone removal and larger shaft for drilling final hole diameter) and sequential drilling technique (increasing hole diameter sequentially until desired hole size is achieved) to reduce the thermal damage in bone.…”

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.

“…The Simplified Drilling (SD) technique, is an option for site preparation for implant placement, characterized by the use of only two drills: an initial and a final one, with the diameter of the preparations chosen for that site. Among the advantages of the SD technique, we can highlight the reduction in the possibility of perforation angulation error during site preparation and a shorter surgical time [6][7][8][9][10][11][12][13][14][15][16].…”

ABSTRACT Introduction: The predictability of osseointegration depends on a non-traumatic surgical technique that maintains cell viability. It is known that during the drilling osteotomy for implant placement occurs heat generation, being able to influence osseointegration due to thermal damage. The objective of this research was to evaluate and compare the heat generated by the drills during the preparation of surgical sites for implant placement between two different techniques: simplified (Simplified Drilling, SD) and conventional, in an in vitro model. Material and methods: Fifty implant site preparations were performed in segments of bovine ribs, divided into two groups, with the respective drill sequences: control group, conventional preparation, Ø2.0mm spear drill and Ø2.15mm, Ø2.85mm, Ø3.35mm, Ø3.85mm twist drills; SD group, Ø2.15mm and Ø3.85mm twist drills. The measurement of the temperature variation generated by each drill in each group was performed by an infrared thermal camera at three points in the bovine rib segment. Results: The temperature variations at one and thirteen millimeters below the drilling site were, respectively, 0.51±0.64°C and 0.46±0.59°C for the control group, and 0.62±0.76°C and 0.5±0.86°C for the SD group. No statistically significant differences were found between the control and SD groups in relation to heat generation in any of the evaluated points; p=0.288 and p=0.584, respectively for analyzes one and thirteen millimeters below the drilling site. Discussion: The technique of implant site preparation can be simplified, using only two drills in this modality, without showing significant differences in relation to heat generation when compared to the conventional preparation technique.
