    Ultrasonic characterization of the bone-implant interface

    Keywords: Biomechanics, bone, implant, interface, acoustics, nanoindentation, characterization, quantitative ultrasound.

    Implants are often employed in orthopaedic and dental surgeries. However, risks of failure, which are difficult to anticipate, are still experienced and may have dramatic consequences. Failures are due to degraded bone remodeling at the bone-implant interface, a multiscale phenomenon of an interdisciplinary nature which remains poorly understood. The objective of this study is to provide a better understanding of the ultrasonic response of the bone-implant interface, which will allow to study the evolution of the biomechanical properties of bone tissue around an implant during the osseointegration process. To do so, a dedicated implant model will be used, which allows to work under standard conditions.

    Different experimental configurations will be considered, based on feasibility studies already carried out by our group. In particular, the high frequency response of the interface will be tested with different angles of incidence. Moreover, dedicated circular transducers generating transverse wave modes will be considered. The results will be compared with other measurements carried out using various experimental modalities.

    The results will be used to design effective loading clinical procedures of implants and to optimize implant conception, leading to the development of therapeutic and diagnostic techniques.

    The candidate will have a Master degree in mechanics, material science or acoustics. No particular knowledge in Medicine or Biology is required but the candidate is expected to be interested by multidisciplinary approaches. He/she will validate the experimental results with models developed by our group. The net salary will be commensurate with the expertise of the candidate and comprised between 1800 € and 2100 € per month.

    The work will be done in the MSME laboratory in Créteil and in the ETS, Montreal. This project also involves mobility at the European level. The candidate will work within a multidisciplinary team of 15 persons (including engineers, biologists and clinicians), all studying the biomechanical properties of the bone-implant interface founded by the European Research Council (ERC Consolidator Grant 2015).
