Evolutionary Algorithm Optimization of Staggered Biological or Biomimetic Composites Using the Random Fuse Model

Roberto Guarino, Gianluca Costagliola, Federico Bosia

In Nature, biological materials such as nacre, bone, and dentin display an enhanced mechanical strength due to their structure characterized by hard inclusions embedded in a soft matrix. This structure has inspired the design of artificial materials with o ...

Effect of a pathological scapular tilt after total shoulder arthroplasty

Dominique Pioletti, Alexandre Terrier, Alain Farron

Total shoulder arthroplasty (TSA) is an accepted and most successfully used treatment for different shoulder pathologies. Different risk factors for the failure of the prosthesis are known. A pathological scapular orientation, observed in elderly people or ...

Hydro-mechanical coupling in the periodontal ligament: A porohyperelastic finite element model

Matteo Galli, Joël Cugnoni, Marzio Bergomi

Harmonic tension–compression tests at 0.1, 0.5 and 1 Hz on hydrated bovine periodontal ligament (PDL) were numerically simulated. The process was modeled by finite elements (FE) within the framework of poromechanics, with the objective of isolating the con ...

Three-dimensional morphometry of strained bovine periodontal ligament using synchrotron radiation-based tomography

John Botsis, Joël Cugnoni, Marzio Bergomi, Marco Stampanoni, Philipp Schneider

The periodontal ligament (PDL) is a highly vascularized soft connective tissue. Previous studies suggest that the viscous component of the mechanical response may be explained by the deformation-induced collapse and expansion of internal voids (i.e. chiefl ...

Load Response of Periodontal Ligament: Assessment of Fluid Flow, Compressibility, and Effect of Pore Pressure

John Botsis, Marzio Bergomi, Aïssa Mellal

The periodontal ligament (PDL) functions both in tension and in compression. The presence of an extensive vascular network inside the tissue suggests a significant contribution of the fluid phase to the mechanical response. This study examined the load res ...

The role of the fluid phase in the viscous response of bovine periodontal ligament

John Botsis, Joël Cugnoni, Marzio Bergomi

The mechanical response of the periodontal ligament (PDL) is complex. This tissue responds as a hyperelastic solid when pulled in tension while demonstrating a viscous behavior under compression. This intricacy is reflected in the tissue's morphology, whic ...

Epiprofin/Sp6: A new player in the regulation of tooth development

Lucia Jimenez Rojo

Odontogenesis is governed by a complex network of intercellular signaling events between the dental epithelium and mesenchyme. This network leads to the progressive determination of tooth shape, and to the differentiation of these tissues into enamel-produ ...

Mechanical response of periodontal ligament: Effects of specimen geometry, preconditioning cycles and time lapse

John Botsis, Marzio Bergomi

This study was conducted as part of research line addressing the mechanical response of periodontal ligament (PDL) to tensile-compressive sinusoidal loading The aim of the present project was to determine the effect of three potential sources of variabilit ...

Regional structural characteristics of bovine periodontal ligament samples and their suitability for biomechanical tests

Marzio Bergomi

Mechanical testing of the periodontal ligament requires a practical experimental model. Bovine teeth are advantageous in terms of size and availability, but information is lacking as to the anatomy and histology of their periodontium. The aim of this study ...

Experimental and numerical investigations on the fluid contribution to the tensile-compressive mechanical behavior of the bovine periodontal ligament

Marzio Bergomi

Orthodontic treatments are all based on the experimental evidence that teeth can be forced to move in the dental arch by means of applied mechanical forces. Since it allows for prediction of dental mobility, the mechanical characterization of the tissues i ...
