Abstract

Stability of Bone Integrated implants is influenced by the bond between bone and implant. This can be evaluated using Resonance Frequency Analysis (RFA). Disagreement exists amongst experts concerning time to activate or ‘load’ the implant. Current practice is 6 to 12 weeks. Particular caution is exercised in revision surgery. Here we present a case of a 62 year-old gentleman implanted with a Bone Anchored Hearing Aid (BAHA). RFA measurements identified instability in the first implant, loading was postponed and the implant lost. RFA identified higher stability following revision BAHA. These values facilitated successful loading at two weeks. This is the first report of the clinical usefulness of RFA to expedite loading time well below standard protocol in revision surgery.
