The Bonebridge is an ACTIVE TRANSCUTANEOUS bone conduction implant whose transducer is implanted in the bone and driven across intact skin, so it does NOT require OSSEOINTEGRATION of a percutaneous abutment (and so avoids skin reactions around a post). It is approved from about age 5 in many regions but the manufacturer's labelling and local approvals vary, MRI is permitted under specified conditions (commonly up to 1.5 T with artefact), and for single-sided deafness the requirement is that the GOOD ear has thresholds of 20 dB HL or BETTER.
