Competency information

Details

Manufacture and provide a deep- buried implant recognising the use of 3D data, correct anatomical shape, production of the defect bone analogue, post processing the surface for improved biocompatibility, placement and fixation.

Considerations

Patient Selection and Management

  • The implant patient: aetiology and assessment of condition.
  • Medicolegal implications of implantable prostheses. EU, US and UK legislation for implantable prostheses.
  • Sterilisation techniques:
  • effects of sterilisation techniques upon physical and chemical properties of implants
  • microbial contamination
  • effects of contamination.

Manufacturing

  • Manufacturing techniques of custom made alloplastic implants:
  • 3D modelling
  • 3D patient analogue of the defect bone
  • custom mould manufacture to form the correct contour
  • post processing of the materials to achieve the best bio- compatibility
  • different sterilisation procedures.
  • Effects of manufacturing techniques on the properties of implants.
  • Calculation of physical dimensions of alloplastic implants relating to mechanical and chemical properties of the material selected.
  • Effect of bone density on fixation design.

Fixation

  • Interface problems, bone cement, porous ingrowth, direct bonding, interface and passive fixation.
  • Effects of fixation on implant function.

Three-Dimensional Data

  • Different modalities of obtaining digital data (CT, MRI, surface data acquisition) and new developments in imaging.
  • 3D volumetric and 3D surface data acquisition.
  • Comparative analysis of methods of obtaining 3D data and accuracy.
  • Identification of principle anatomical structures on X-rays, CT, MRI and surface data scans.
  • Principles of image-guided surgery and its applications in maxillofacial and craniofacial surgery.
  • Dicom data, conversion to a 3D data and 3D images.
  • Anatomical landmarks and artefacts for the different methods of data collection.
  • Accuracy of 3D reconstructed images.
  • 3D software programs available for pre-operative planning and image manipulation and assessment in pre/postoperative outcomes.
  • 3D software systems to predict ideal implant locations (i.e. Simplant). 3D templates to locate implants at surgery.
