Reduction of scapulohumeral subluxation with posterior augmented glenoid implants in anatomic total shoulder arthroplasty: Short-term 3D comparison between pre- and post-operative CT

Alexandre Terrier, Alain Farron, Patrick Goetti

Background: Failure rates in anatomic total shoulder arthroplasty (aTSA) are higher in case of asymmetric glenoid bone loss secondary to posterior wear, and in persistent static posterior subluxation of the humeral head (PSH). ...

A review of the concepts, recent advances and niche applications of the (photo) Fenton process, beyond water/wastewater treatment: Surface functionalization, biomass treatment, combatting cancer and other medical uses

Stefanos Giannakis

The Fenton reaction was discovered over 120 years ago, yet our understanding of the complete reaction mechanism of the seemingly simple iron and hydrogen peroxide reaction (Fe + H2O2) remains unclear, thus limiting its full potential. In this work, the aim ...

Description of Fornasinius hermes sp. nov. (Coleoptera, Cetoniidae, Goliathini)

Michele De Palma

Fornasinius hermes sp. nov. is described from North-East Uganda; type locality: Mt Morungole, Kidepo valley. The new species is reminiscent of Fornasinius fornasini Bertoloni, 1852 and Fornasinius aureosparsus (Neervoort Van De Poll, 1890), but presents a ...

Scaffold requirements for periodontal regeneration with enamel matrix derivative proteins

John Christopher Plummer, Laurent Mirko Dejace, Peter Fischer, Alessandra Apicella, Matteo Gregorio Modesto Marascio

Periodontitis affects the attachment of natural teeth, and infection or inflammation associated with periodontitis may affect peri-implant tissues. Enamel matrix derivative (EMD) proteins provide stimulation for self-regeneration of the damaged tissue when ...

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

Joël Cugnoni, John Botsis, Marzio Bergomi, Matteo Galli

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 ...

In vivo loading increases mechanical properties of scaffold by affecting bone formation and bone resorption rates

Dominique Pioletti, Alireza Roshan Ghias

A successful bone tissue engineering strategy entails producing bone-scaffold construct with adequate mechanical properties. Apart from the mechanical properties of the scaffold itself, the forming bone inside the scaffold also adds to the strength of the ...

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

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

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

Joël Cugnoni, John Botsis, 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 ...

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 ...
