Tunable and cell-responsive 3D poly(ethylene glycol) microenvironments for the development of tissue models

Stéphanie Elisabeth Metzger

The recapitulation of tissue organization and function in vitro is one of the main objectives of tissue engineering. Proper tissue function depends on the spatial assembly and interactions between key components such as cells, growth factors, signaling cue ...

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 ...

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 ...

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 ...

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 ...

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 ...

With applications to the periodontal ligament: a nonlinear large strain viscoelastic law

Jörn Justiz

The soft tissue, called periodontal ligament (PDL), that connects the alveolar bone and the tooth root accounts to a large extent for the mobility, stress-distribution and, due to its viscoelastic properties, damping of the bone-tooth complex. The accurate ...
