“…The drill bit was modelled as a rigid body in order to reduce the computing time and resources, with high stiffness (220-240 GPa) when compared with the cortical bone equal to 16 GPa [7]. The cortical bone behaviour was simulated using an elastic-plastic material, depending on the strain rate and the failure criterion of the material.…”

PrefaceThis book contains the abstracts and full papers presented at the IEEE 4th Portuguese Meeting on Bioengineering (ENBENG) organized by the IEEE Engineering in Medicine & Biology Society (EMBS) Chapter of the IEEE Portugal Section that was held in "Atmosfera m", in the city of Porto, between 26th and 28th, February of 2015.The Portuguese Meeting on Bioengineering is one of most important meetings organized in Portugal related with the Bioengineering field and where students and researchers present and discuss the preeminent work developed in Portugal in the field. The meeting has been organized since 2011: the first was held in Lisbon, in 2011; the second in Coimbra, in 2012; and the third occurred in Braga, in 2013.ENBENG2015 had 107 works submitted, from which 52 were accepted for oral presentations distributed by 10 sessions, and 31 as posters. The submissions involved authors from several Portuguese Institutions, which shows the importance of the Bioengineering and Biomedical Engineering in Portugal nowadays. Additionally, 9 submissions were from foreign countries. The received contributions address several topics related to Bioengineering, including Biomaterials, Nanobiotechnology,

“…Before the insertion of screw, drilling then tapping are conducted [2]. About 95% of post-trauma therapies need drilling holes that are needed to install the screws for plate attachments or other prosthetics or for fixing and correcting fractures of bone [3].…”

“…In 2012, Sezek et al analysed change of temperature during drilling of bone by application of Finite Elements Method (FEM) by deciding the points drilling in bone and found a secure zone or below temperature of 45 o C [21]. The numerical method in bone drilling simulation could be a foundation for surgical tools optimization including for determination of their properties [22] and provide tools for development of surgical operations [2].…”

Abstract. Thermal necrosis results fracture problems and implant failure if temperature exceeds 47 o C for one minute during bone drilling. To solve this problem, this work studied a new thermal model by using three drilling parameters: drill diameter, feed rate and spindle speed. Effects of those parameters to heat generation were studied. The drill diameters were 4 mm, 6 mm and 6 mm; the feed rates were 80 mm/min, 100 mm/min and 120 mm/min whereas the spindle speeds were 400 rpm, 500 rpm and 600 rpm then an optimization was done by Taguchi method to which combination parameter can be used to prevent thermal necrosis during bone drilling. The results showed that all the combination of parameters produce confidence results which were below 47 o C and finite element analysis combined with Taguchi method can be used for predicting temperature generation and optimizing bone drilling parameters prior to clinical bone drilling. All of the combination parameters can be used for surgeon to achieve sustainable orthopaedic surgery.

“…A numerical model based on the FEA programs such as ANSYS, ABAQUS, MSC/MARC, and SolidWorks, etc. [13][14][15][16] is frequently used to predict complicated problems, complex geometry and boundary condition. Consider the scenario of a fractured bone supported by a plate.…”

“…To analyze this distribution, it is necessary to determine the mechanical properties of the plate such as the Poisson's ratio and Young's modulus [17]. Furthermore, FEA is also commonly used to analyze problems in other biomechanical fields such as forces acting on screw implants, drilling and tapping processes (to prevent drill-bit breakthrough of bone) as well as making predictions in orthodontics [13][14]16].…”

Abstract. Biomaterials, such as Hydroxyapatite (HA) and Bioactive glass (BG) have been increasingly implemented in bone substitution due to their biocompatibility and close resemblance to the mineralized phase of human bone. Furthermore, biomaterials can be synthesized from natural sources with calcium-based skeletal structures. In this study, HA and BG were synthesized from bovine bone and mollusk shell, and mixed together to form HA-BG composite biomaterial. Then, the mixtures were compressed into a compact scaffold with dimension of 8×6×8 mm 3 , sintered at 1,000 ˚C for 3 hours and cooled down to room temperature. The compressive strengths of all specimens were evaluated using a universal testing machine. Experimental design was implemented to evaluate the significant factors of forming conditions on the mechanical property of the scaffold. The results revealed that all forming factors have a significant effect on the mechanical property of the composite scaffolds. Consequently, the highest compressive strength (136.92 MPa) was obtained from the scaffold with a 5.85 wt% of BG, 23.41 MPa of pressure and 65.64 seconds of holding time. In addition, Finite Element (FE) modeling was performed to simulate the HA-BG plate under combined loading, and showed that stresses were concentrated near the fracture site and the screw holes.
