Resumo(s)
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 microcracks
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.
