Temperature Excursions at the Pulp-Dentin Junction during the Curing of Light-Activated Dental Restorations

M. Jakubinek[1,2], C. Neill[1], C. Felix[3], R. Price[2,3], M. White[1,2]

[1]Departments of Chemistry and Physics, Dalhousie University, Halifax, NS, Canada
[2]Institute for Research in Materials, Dalhousie University, Halifax, NS, Canada
[3]Department of Dental Clinical Sciences, Dalhousie University, Halifax, NS, Canada

Heat produced during the curing of light-activated dental restorations could damage the dental pulp. Given the prevalence of composite restorations and the importance of avoiding injury to the pulp, efforts should be made to minimize the temperature increase that occurs at the pulp ... Read More

Image Based Mesh Generation for Realistic Simulation of the Transcranial Current Stimulation

R. Said[1], R. Cotton[1], P. Young[1], A. Datta[2] , M. Elwassif[2], and M. Bikson[2]
[1]Simpleware Ltd, Exeter, UK
[2]Department of Biomedical Eng, The City College of New York, USA

Electrical stimulation of the brain involves the application of currents delivered through scalp electrodes to modulate brain activity, known as Transcranial Current Stimulation (TCS). A critical factor for TCS efficacy and safety is the “spatial focality” of induced neuronal modulation. ... Read More

Using COMSOL Multiphysics for Modeling of Musculoskeletal Biomechanics

R. L. Spilker
Department of Biomedical Engineering, Rensselaer Polytechnic Institute, New York, USA

In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: * Why is COMSOL particularly powerful for modeling physiology? * Modeling soft tissues like cartilage * Optimization to determine ... Read More

Simulation of Bio-medical Waveguide in Mechanical and Optical fields new

Y. Xin[1], A. Purniawan[1], L. Pakula[1], G. Pandraud[1], P. J. French[1]
[1]Technology University of Delft, Delft, Netherlands

This paper presents a freestanding waveguide to achieve the goal of detecting anastomosis leakage after colon surgery. The freestanding part is a thin membrane consisting of TiO2 rib and SiN ridge. This freestanding waveguide is designed both mechanically and optically to maintain ... Read More

Multiphysics Modeling of Electrode-Driven Renal Denervation for Hypertension Treatment new

M. Miliani[1], F. Piccagli[1], C. Silvestro[1]
[1]Medtronic Invatec S.p.A., Roncadelle, Italy

Introduction: Chronic arterial hypertension (HTN) is a pathological condition characterized by prolonged high level of arterial blood pressure causing major damages to several human body apparata. Renal sympathetic denervation (RDN) has been found to effectively reduce systemic blood ... Read More

Analysis of 3D Biocompatible Additive Structure Using COMSOL Multiphysics® Software new

E. Lacatus[1], M. A. Sopronyi[2], G. C. Alecu[1], A. Tudor[1]
[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

For biocompatible prosthetics, from dental implants up to bone parts, manufacturers have to find the best way to correlate process parameters and the material properties as to meet the unique needs of individuals. Additive manufacturing techniques aim at creating complex biocompatible ... Read More

On the Influence of Cancellous Bone Structure upon the Electric Field Distribution of Electrostimulative Implants new

U. Zimmermann[1], R.Bader[2], U. van Rienen[1]
[1]Institute of General Electrical Engineering, University of Rostock, Rostock, Germany
[2]Department of Orthopaedics, University Medicine Rostock, Rostock, Germany

Since the 1980s, the accelerating effect of electromagnetic fields on bone regeneration is used to treat complicated fractures and bone diseases. At the University of Rostock, an electrostimulative hip revision system is developed, basing on the method of Kraus-Lechner. This method ... Read More

From Music to Non-Invasive Therapies via COMSOL Multiphysics® Models new

E. Lacatus[1], G. C. Alecu[2], A. Tudor[2], M. A. Sopronyi[3]
[1]Polytechnic University of Bucharest, Bucharest, Romania
[2]Student-Polytechnic University of Bucharest, Bucharest, Romania
[3]INFLPR -National Institute for Laser Plasma and Radiation Physics, Bucharest, Romania

Vibration and music therapies are non-invasive treatments having effective results although their basics are still disputed. By the application of COMSOL Multiphysics® software for modeling and analysis, some of the nonlinear physical phenomena laying on these applications may be ... Read More

Determination of the Mechanical Properties in the Avian Middle Ear by Inverse Analysis new

P. Muyshondt[1], J. Soons[1], D. de Greef[1], J. Peacock[1], J. Dirckx[1]
[1]University of Antwerp, Antwerp, Belgium

The middle ear of birds is a fascinating mechanical system, as it contains only one bony ossicle, compared to three in mammals, yet its auditory performance is not substantially worse. Its design resembles some currently used middle ear prostheses, so the understanding of its working ... Read More

Analysis to Determine Optimum Strain Gauge Locations for SENSEWHEEL new

T. Suzuki[1], C. Holloway[1], S. Taylor[1]
[1]University College London, London, UK

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx ... Read More
