Rethinking implant failures to improve patient outcomes

Implant Corrosion & Failure

Project Summary

A new dental or orthopaedic implant is expected to reduce pain and improve quality of life. Unfortunately, 5% of orthopaedic implants and up to 20% of dental implants fail prematurely. Orthopaedics and dentistry face similar challenges, yet insights are seldom shared across disciplines. This initiative unites dentists, orthopaedic surgeons, imaging and materials scientists to elevate biomedical implant performance. Western houses Canada’s largest orthopedic implant retrieval lab and is now assessing failed dental implants. This interdisciplinary team is identifying the root causes of adverse clinical outcomes linked to implant materials, including degradation mechanisms such as corrosion, to inform strategic research directions and improve patient safety and outcomes.
