Modal analysis for implant stability assessment: Sensitivity of this methodology for different implant designs.

Objective: To investigate the influence of implant design on the change in the natural frequency of bone-implant system during osseointegration by means of a modal 3D finite element analysis.

Methods: Six implants were considered. Solid models were obtained by means of reverse engineering techniques.

Multibody modelling of ligamentous and bony stabilizers in the human elbow.

Unlabelled: The elbow ligamentous and bony structures play essential roles in the joint stability. Nevertheless, the contribution of different structures to joint stability is not yet clear and a comprehensive experimental investigation into the ligament and osseous constraints changes in relation to joint motions would be uphill and somehow unattainable, due to the impossibility of obtaining all the possible configurations on the same specimen. Therefore, a predictive tool of the joint behavior after the loss of retentive structures would be helpful in designing reconstructive surgeries and in pre-operative planning.

Influence of thread shape and inclination on the biomechanical behaviour of plateau implant systems.

Objective: To assess the influence of implant thread shape and inclination on the mechanical behaviour of bone-implant systems. The study assesses which factors influence the initial and full osseointegration stages.

Methods: Point clouds of the original implant were created using a non-contact reverse engineering technique.
