3D Assessment of Mandibular Growth Based on Image Registration: A Feasibility Study in a Rabbit Model

Background. Our knowledge of mandibular growth mostly derives from cephalometric radiography, which has inherent limitations due to the two-dimensional (2D) nature of measurement. Objective. To assess 3D morphological changes occurring during growth in a r ...

Development of a Bisphosphonate Delivering Hydrogel for the Augmentation of Impaired Peri-Implant Bone

Ulrike Kettenberger

Osteoporosis is a major health problem in our aging society. This metabolic disease, which is characterized by a deterioration of the bone microarchitecture and a significant loss of bone mass, is affecting a rising number of mostly elderly patients. The m ...

Does locally delivered Zoledronate influence peri-implant bone formation? – Spatio-temporal monitoring of bone remodeling in vivo

Dominique Pioletti, Ulrike Kettenberger, Julien Ston

Bisphosphonates are known for their strong inhibitory effect on bone resorption. Their influence on bone formation however is less clear. In this study we investigated the spatio-temporal effect of locally delivered Zoledronate on peri-implant bone formati ...

External Mechanical Microstimuli Modulate the Osseointegration of Titanium Implants in Rat Tibiae

John Botsis, Joël Cugnoni

Purpose. To assess the effect of external mechanical microstimuli of controlled magnitude on the microarchitecture of the peri-implant bone beds in rat tibiae. Materials and Methods. Tibiae of forty rats were fitted with two transcutaneous titanium cylinde ...

Injectable calcium phosphate cement for augmentation around cancellous bone screws. In vivo biomechanical studies

Dominique Pioletti, Vincent Stadelmann

In lower cancellous apparent bone density, it can be difficult to achieve adequate screw fixation and hence stable fracture fixation. Different strategies have been proposed, one of them is through augmentation using calcium phosphate cement in the region ...

Implementation of the "loaded implant" model in the rat using a miniaturized setup - description of the method and first results

John Botsis, Joël Cugnoni, Philippe Bonhote

Objective To miniaturize the loaded implant model to permit its application to small rodents. In this model, two titanium implants are placed 8 mm apart with their heads protruding from the skin and are forced together by a dedicated actuator. To assess th ...

Osteoconductive surfaces generated from peptide functionalized poly(2-hydroxyethyl methacrylate-co-2-(methacryloyloxy)ethyl phosphate) brushes

Harm-Anton Klok, Dusko Paripovic

Modification of bone implant materials with biofunctional surfaces that facilitate osteoblast adhesion and promote matrix mineralization is an attractive strategy to improve osseointegration. This manuscript discusses the preparation and properties of RGD ...

Simultaneous and multisite measure of micromotion, subsidence and gap to evaluate femoral stem stability

Dominique Pioletti, Alexandre Terrier, Miguel Gortchacow

The initial stability of cementless femoral components is crucial for the long-term success of total hip arthroplasty. This has been reported in animal and clinical studies. Until now, the stability was evaluated by the measurement of relative micromotion ...

Effect of Micromotion on Morphogen Dynamics in Peri-Implant Healing

Miguel Gortchacow

The primary stability of cementless femoral components is crucial for the long-term success of total hip arthroplasty. We know that the healing phase after surgery is a complex biological process, which is affected by the mechanical environment. Implant lo ...
