Double jaw surgery

Protruding jaw correction (주걱턱)

EU begins by separating whether the protruding jaw comes from an over-developed mandible, a retruded maxilla, or both — each requires a different surgical plan.

Who it suits

Anterior crossbite where the lower teeth sit in front
Protruding jaw combined with facial asymmetry
Chewing or speech difficulty from the malocclusion

Technique highlights

Diagnosis separates maxillary from mandibular causes before planning
Some cases are solved with mandible-only surgery instead of both jaws

Surgical steps

Occlusal analysis with lateral radiographs and 3D CT
Deciding orthodontics-first or surgery-first with the orthodontist
Setting back the mandible and adjusting the maxilla as required

Recovery & aftercare

The same protocol as double jaw surgery: wafer, liquid diet and face band

Risks & things to consider

A dental-only protrusion may be corrected with orthodontics alone

Frequently asked questions

Does every protruding jaw need double jaw surgery?

No. EU explains that protrusion has several patterns: some come from the mandible alone and are treated with mandibular surgery, while a retruded maxilla requires both jaws.
