  • Ph.D. offer within industry "mechanical performance of the bone-implant systems", France

    Location: Glad Medical, Laboratoire de Biomécanique Appliquée (UMRT24 Ifsttar / AMU), Marseille,France

    Contract Type: Full Time (3 years)

    Context & Objectives
    Surgical procedures to replace dental implants offer tremendous opportunities for biomechanical simulations
    to improve clinical techniques. The short- and long-term clinical outcomes of dental implants
    are highly dependent on the mechanical environment of the bone-implant system. It is very difficult to
    generalize this environment because there are large differences between patients in parameters such
    as bone geometry and bone-implant mechanical properties. Therefore, in order to develop a realistic
    biomechanical simulation tool for surgical planning, all these parameters must be taken into account.

    Glad Medical, in close collaboration with the Laboratory of Applied Biomechanics (Aix-Marseille University)
    and clinicians, has recently developed a biomechanical model of implanted human mandible
    and maxilla, as well as an estimation pipeline allowing to personalize the model based on clinical
    images. So far, the group has focused on personalizing the geometry and heterogeneous mechanical
    properties of the bone. The current Ph.D. topic aims to improve this pipeline by adding a mechanical
    performance prediction module. This module will be based on innovative criteria and methods that take
    into account the potential risk of fatigue failure, the quality of long-term bone-implant osseointegration,
    bone damage and any other relevant criteria.

    The Ph.D. work includes:
    • The processing of CT /CBCT images of patients
    • Developing the FE patient-specific model with existing automated Python and Tcl/Tk scripts
    • Implementing the application of patient-specific masticatory force into the model
    • Extension of the FE model by implementing the mechanical performance prediction module
    • Performing mechanical tests on the bone-implant system

    Numerical Simulation, Mechanics of Materials and Structures, Biomechanics; Image-based Modeling;
    Dental Implants; Fatigue; Osseointegration

    Candidate profile
    The candidate should have a fair understanding of finite element simulation, with knowledge of
    continuum mechanics, biomechanics, and numerical methods. He/She should have a solid background
    in computational programming, and also have an interest in the medical devices.

    Work environment
    The work will take place in the Glad Medical R&D office on the premises of medical campus of Aix-Marseille University . The Ph.D. will begin in January 2022.
