Stress analysis and fixation problems in joint replacement

The aims and scopes of stress analyses, and the three most commonly applied methods (i.e. experimental strain-gauge techniques, analytical `closed-form' solutions, and finite element methods) are discussed with particular reference to total hip replacemen

A 3-dimensional mechanical analysis of the tooth-jaw system

This analysis was aimed at the development of a usable mathematical relation between arbitrary 3-dimensional loading and elastic or initial displacement of a tooth, dependent on the most essential parameters of the tooth-jaw structure. Such a relation is important for structural analyses of orthodontic appliances and dental implants, since their mechanical behaviour depends on the characteristics of the elastic support. A 3-dimensional mathematical model, based on finite element methods, was develope
