About Dr. K
Meet Dr. K
Southern California’s first
airway orthodontist.
Dr. Yoram Kohanzadeh is the first and only certified airway orthodontist in all of Southern California — and the only certified airway specialist in the entire San Fernando Valley. He is also the creator of the BioX (Bio Expansion) protocol.
How cleft palate
changed everything
Airway orthodontics chose Dr. K — not the other way around. During his residency treating cleft lip and palate patients, he faced a problem that traditional orthodontics couldn’t solve: these patients have a cleft in the roof of the mouth, which means conventional palatal expansion simply isn’t an option.
That constraint forced Dr. K to think differently. He needed to find a way to grow the jaws biologically — to work with the body instead of against it. That’s where the idea for BioX was born.
Dr. K was fortunate to have trained in multiple orthodontic philosophies, including the Damon self-ligating system — a philosophy his practice still uses today. That biomimetic braces approach was one of the first times he witnessed biological jaw growth happening in real time, even when other orthodontic philosophies said it wasn’t possible. He saw that with the right wires and brackets, you could achieve mild, passive growth of the jaws.
He pushed that concept further with BioX — and the rest of the connections became obvious. If you could grow jaws biologically, you could open airways. If you could open airways, you could change lives. Sleep, breathing, focus, behavior, health — it all traces back to how the jaws develop. And once you see that, you can’t unsee it.
That journey led Dr. K to become the first orthodontist in Southern California to earn certification through Airway Health Solutions — formalizing what he’d already been practicing for years.
What makes Dr. K
different
It’s not just the certification. It’s the philosophy behind every treatment decision.
BioX:
Bio Expansion
BioX was born out of clinical necessity. During his residency, Dr. K treated cleft lip and palate patients who couldn’t undergo traditional palatal expansion — because there’s a cleft in the roof of the mouth. He had to find another way.
Drawing on his training in the Damon self-ligating philosophy — where he first witnessed that mild, passive biological jaw growth was actually possible — Dr. K developed BioX: a biomimetic expansion protocol that mimics the body’s own biology to grow the jaws slowly and naturally.
Unlike mechanical expanders that use aggressive force on a fixed timeline, BioX is fine-tuned to each patient’s own natural growth speed. No two patients grow at the same rate — a 7-year-old expands differently than a 10-year-old, and a 40-year-old differently than a teenager. BioX respects that. Your body leads. The appliance guides.
And here’s what surprises most people: BioX works at almost any age. Your body is far more malleable than you’ve been told. Dr. K’s oldest BioX patient was 67 years old. The jaws can still grow, remodel, and expand — if you use the right approach.
This isn’t just Dr. K saying it. Bestselling journalist James Nestor explored jaw expansion in his book Breath: The New Science of a Lost Art — a book Joe Rogan called “awesome” on JRE Episode #1506. Nestor used a traditional mechanical expander (the Homeoblock) and described the experience as uncomfortable and painful. BioX takes a fundamentally different approach — slow, biological, biomimetic growth that works with the body’s own remodeling process instead of forcing it. Less pain. Better adaptation. More natural results.

The result: broader arches, more room for the tongue, a wider airway, and naturally aligned teeth — achieved through biology, not brute force. BioX can be used alongside Vivos, Myobrace, or as a standalone protocol for patients of all ages.
