A New Bone-Conduction Implant: What the Early Sentio Numbers Mean

If conventional hearing aids have never worked for you, the reason is often mechanical, not a matter of volume. When hearing loss is conductive or mixed, sound cannot get cleanly through the outer or middle ear in the first place, so turning it up does not help. Bone conduction routes around the blockage and sends sound through the skull straight to the inner ear. A new device in this category, Oticon Medical’s Sentio system, now has its first clinical numbers, and it is already available in Canada.

What Sentio is

Sentio is Oticon Medical’s first active transcutaneous bone-anchored hearing system. It has two parts: the Sentio 1 Mini sound processor worn outside, and the Sentio Ti implant placed under the skin. Magnets hold the two together across intact skin.

The “transcutaneous” part is the point. Older percutaneous bone-conduction devices used an abutment, a small fixture that protruded through the skin. Abutments work, but they need daily cleaning and carry a real risk of skin irritation and infection around the site. Sentio keeps the skin closed and uses a magnet instead. Nothing sticks out.

Who it is for

The manufacturer’s indication is for candidates aged 12 and older with conductive or mixed hearing loss, or single-sided deafness (profound sensorineural loss in one ear). That indication is the same wording used in its US FDA clearance; in Canada what governs availability is Health Canada licensing, and the system has been on the Canadian market since 2025, so a Canadian team can assess you against it directly. These are exactly the situations where air-conduction aids tend to fall short, so the candidate pool is specific and real.

What the early data shows

An early clinical-outcomes paper in The Laryngoscope (2026) reports the first results in patients with conductive or mixed loss: gains in hearing thresholds, improvements in speech intelligibility, surgical safety, and short-term device tolerability. These are early outcomes with short follow-up, the kind of readout that shapes which device a surgeon recommends rather than the final word on long-term performance. Read it as encouraging early evidence, not a finished story.

The trade-offs

A closed-skin, magnetic design lowers the skin-complication profile that plagued abutment systems, and there is nothing protruding to catch or clean. The trade-offs are the ones common to every transcutaneous device: the signal has to cross the skin, and magnet strength has to balance secure hold against comfort and skin pressure. Those are fit questions, best answered by a candidacy assessment rather than a brochure.

It is available in Canada

This is not a device you have to cross a border or wait years for. Oticon Medical Canada launched Sentio in Canada in April 2025, so a Canadian ENT and audiology team can assess and place it now.

What to ask before you commit

  • Am I a candidate? Your specific loss type and bone quality decide this.
  • MRI compatibility, and at what field strength, since implants and scanners interact.
  • Magnet comfort over a full day, and how skin pressure is managed.
  • Processor cost, battery or charging, and replacement-and-upgrade cycle.
  • What provincial funding, private insurance, or a device program will cover, which varies a great deal across Canada.
  • The repair and revision path if the processor or implant needs service.

This is information, not medical advice. An ENT surgeon and an audiologist are the people who can tell you whether Sentio fits your ear.

The honest read

Sentio is a real option for a specific group, with early but promising numbers and Canadian availability today. The open question is rarely whether the engineering is clever. It is whether the device fits your ear and your budget, and whether the funding will meet you there.
