Correcting the jaw itself, not just the teeth.

For bite and jaw-position cases that braces alone can’t fully correct — corrective jaw-bone surgery (orthognathic surgery), carefully planned and coordinated from consultation through recovery.

A treatment we want to be genuinely known for — especially for patients travelling to Japan for care.

Some bite and jaw-alignment problems — a significant under- or overbite, facial asymmetry, or a jaw that didn’t grow quite in balance — go beyond what braces or aligners can fix on their own. Orthognathic surgery repositions the jaw bone itself, usually alongside orthodontic treatment before and after, for a result that’s both functional and facially balanced.

What the treatment involves

Planning starts with a thorough assessment — bite, jaw position and facial structure — supported by our in-house CT, so the surgical plan is precise from the outset. Orthodontic treatment typically prepares the teeth beforehand, the surgical correction follows, and further orthodontic work refines the bite afterwards.

Because it’s a surgical procedure on the jaw bone, the operation itself is coordinated with a partner hospital and an oral-maxillofacial surgical team, under general anaesthesia — with our clinic managing the dental and orthodontic side of your care and staying closely involved throughout.

In-house CT planning for jaw surgery

A specialty we are actively building out for international patients

This is an area the clinic is prioritising for patients travelling to Japan specifically for treatment, and we want this page to reflect that properly — with real case examples, the surgical team and hospital partner, typical timelines, and realistic costs, rather than general descriptions alone.

If you are the clinic and reviewing this page: to finish it properly we’ll need a short list of specifics from you — see below.
