Design of Customized Mouthguards with Superior Protection Using Digital-Based Technologies and Impact Tests

Dominique Pioletti, Naser Nasrollahzadeh Mamaghani, Martin Broome

Background In contact sports, an impact on the jaw can generate destructive stress on the tooth-bone system. Mouthguards can be beneficial in reducing the injury risk by changing the dynamics of the trauma. The material properties of mouthguards and their ...

Curable filler material for tubular structures

Andreas Schmocker

A radiopaque composition with low viscosity and increased photopolymerizability for application or filling of hollow structures is disclosed. Moreover, a method to apply and monitor the application and/or the photopolymerization of the composition are pres ...

Fiber density of collagen grafts impacts rabbit urethral regeneration

Peter Frey, Jeffrey Alan Hubbell, Hans Mattias Larsson, Elif Vardar

There is a need for efficient and “off-the-shelf” grafts in urethral reconstructive surgery. Currently available surgical techniques require harvesting of grafts from autologous sites, with increased risk of surgical complications and added patient discomf ...

Implant-based three-dimensional superimposition of the growing mandible in a rabbit model

The reliable assessment of craniofacial morphological changes during growth requires invariant regions for image registration. As these regions have not yet been identified in three dimensions, intra-osseous implants are required as fiducial markers for th ...

Variability of the pullout strength of cancellous bone screws with cement augmentation

Dominique Pioletti

Background: orthopaedic surgeons often face clinical situations where improved screw holding power in cancellous bone is needed. Injectable calcium phosphate cements are one option to enhance fixation. Methods: paired screw pullout tests were undertaken in ...

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 ...

Calcium phosphate cement augmentation of cancellous bone screws can compensate for the absence of cortical fixation

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

An obvious means to improve the fixation of a cancellous bone screw is to augment the surrounding bone with cement. Previous studies have shown that bone augmentation with Calcium Phosphate (CaP) cement significantly improves screw fixation. Nevertheless, ...

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

John Botsis, Joël Cugnoni, Marzio Bergomi

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 ...

Multi-axial mechanical properties of human trabecular bone

In the context of osteoporosis, evaluation of bone fracture risk and improved design of epiphyseal bone implants rely on accurate knowledge of the mechanical properties of trabecular bone. A multi-axial loading chamber was designed, built and applied to ex ...

Microstimulations at the bone implant interface upregulate osteoclast activation pathway

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

Peri-implant bone resorption after total joint arthroplasty is a key parameter in aseptic loosening. Implant wear debris and biomechanical aspects have both been demonstrated to be part of the bone resorption process. However, neither of these two paramete ...

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 ...

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 ...
