Introduction
The boné drilling is a common surgical procedure in clinicai intei-ventions including the dentistry. Although not a novelty in medicine, the penetration
of a sharp tool in the boné tissue continues to be a
clinicai and surgical challenge, as many pertinent
questions still remain without solutions.
Mechanical damage to the boné tissue is one of the
common complication associafed with the drilling
process [l]. An excessive force generated by a
cutting tool can lead to the formation of
micro-cracks and fractures, and even cause permanent
damage in the boné tissue that, in tum, can delay
postoperative recovery [2]. The main goal of this
paper is to investigate the effect of drill speed on
mechanical damage during drilling of solid rigid foam materiais, with similar mechanical properties to the human boné. Experimental tests were
performed on biomechanical blocks instrumented
with strain gauges in different surface positions
during the drilling process. Finite element (FE)
simulations were performed to simulate the drilling
process and validated with experimental results.
Materiais and methods
Experimental tests were conducted on two
biomechanical blocks from Sawbones. Several boles were made, at three different drill speeds, in order to evaluate the influence on the drilling
process. Ali the other parameters were considered
constant (Table l). During the perforation the
strains were recorded through the linear strain
gauges (Figure l). Numerically, a 3D dynamic
model vvas developed using the ANSYS
LS-DYNA. Through the explicit numerical simulation
it is possible to explore the effects of different drill
speeds on the generated stresses near to the hole
and surrounding tissue. The FE mesh is constituted
by the drill bit, the block and an internai cylíndrical
part with a diameter equal to the drill, as shown in
Figure l.

Results and Conclusions
In this study, experimental and numerical models
are proposed to investigate the effect of drill speed
on the stress distribution in boné tissue. The results
show that generated stresses in the material tend to
increase with tool penetration. Figure 2 illustrates
the von-Mises stresses distribution in the
biomechanical blocks. A drill bit with a higher drill speed leads to an increase in von-Mises stresses in the boné. The models proved to be an accurate analysis tool to simulate the stresses distribution in the boné during the drilling process.
