Six Canadian centers have placed 222 extraoral osseointegration implants. Success rates vary, with non-radiated mastoid regions showing high predictability, unlike radiated areas. Further data is needed for definitive expectations.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomaterials Engineering
  • Reconstructive Surgery

Background:

  • Extraoral osseointegration is a reconstructive technique for craniofacial defects.
  • Data on the success rates of extraoral implants, particularly in Canada, is limited.
  • Understanding implant performance across different patient populations and anatomical sites is crucial.

Purpose of the Study:

  • To survey Canadian centers performing extraoral osseointegration.
  • To compare Canadian implant success rates with international data.
  • To identify factors influencing implant success in craniofacial reconstruction.

Main Methods:

  • A survey of Canadian centers involved in extraoral osseointegration.
  • Retrospective analysis of implant placement and success rates.

Related Experiment Videos

  • Comparison of Canadian data with published Swedish and United States' experience.

    • Main Results:

    • Six Canadian centers reported placing 222 implants in 91 patients.
    • Mastoid region implants in non-radiated patients demonstrated high success rates.
    • Radiated patients showed lower and variable success rates depending on anatomical location.

    Conclusions:

    • Canadian extraoral osseointegration data, combined with international experience, provides valuable trends.
    • Success rates are influenced by radiation status and anatomical site.
    • Clearer criteria for craniofacial implant success are needed, differentiating extraoral and intraoral applications.
