BACKGROUND Many (artificial) bone substitute materials are currently available for use in orthopaedic trauma surgery. Objective data on their biological and biomechanical characteristics, which determine their clinical application, is mostly lacking. The aim of this study was to investigate structural and in vitro mechanical properties of nine bone substitute cements registered for use in ortho...

Introduction Displaced fractures of the distal radius are typically repaired by either closed reduction and casting or open reduction with internal plate fixation. This treatment dichotomy fails for elderly patients, where risks associated with open surgery outweigh benefits, and malunions after closed reduction frequently result in deformity. A need exists for minimally invasive fixation which...

Different ceramic substances are offered in the market as bone substitute materials. These include monophasic calcium phosphate ceramics of tricalciumphosphate (TCP) or hydroxyapatite (HA), biphasic calcium phosphate ceramics and multiphasic bio-glasses synthetic calcium phosphate cements. Ceramics with appropriate three-dimensional geometry are able to bind and concentrate bone morphogenetic p...

Composite cements have been shown to be biocompatible, bioactive, with good mechanical properties and capability to bind to the bone. Despite these interesting characteristic, in vivo studies on animal models are still incomplete and ultrastructural data are lacking. The acquisition of new ultrastructural data is hampered by uncertainties in the methods of preparation of histological samples du...

Glass ionomer cements (GICs) are widely used in restorative dentistry.1 In dentistry, one of their advantages over other restorative materials is that they can be placed into tooth cavities without an additional bonding agent.2 They also possess a fluoride-releasing property3 and are relatively biocompatible with the pulp.1 Adhesive property and fluoride release of glass ionomer cement contribu...
