Understanding orthognathic surgery

Orthognathic surgery is used in selected cases to reposition the upper jaw, lower jaw or both. It may be considered when a skeletal discrepancy affects the bite, facial balance or function and cannot be adequately addressed by orthodontic treatment alone.

Jaw discrepancies may affect the relationship between the upper and lower teeth, facial balance and functions such as biting, chewing or speaking. The underlying cause may relate to the position or size of one or both jaws, and the degree of discrepancy varies between individuals.

Assessment usually requires a coordinated view of facial structure, dental alignment and jaw function. Clinical examination and appropriate imaging help determine whether the concern is dental, skeletal or a combination of both.

How the condition is evaluated

Assessment may involve clinical examination, dental records, photographs, imaging and coordination with an orthodontist. Treatment planning considers the jaw relationship, teeth, facial proportions and functional goals.

Treatment and surgical options

Surgery may reposition one or both jaws using planned osteotomies and fixation. Orthodontic treatment may be required before and/or after surgery. The exact sequence is individualised.

Orthognathic treatment is commonly planned in coordination with orthodontic care when tooth position and jaw position both need attention. The sequence may include pre-surgical dental alignment, corrective jaw surgery and post-surgical orthodontic finishing, depending on the individual plan.

Before proceeding, the patient should understand the intended functional and facial changes, the expected treatment stages, recovery requirements and potential risks. Suitability is determined through specialist assessment and coordinated planning.

What patients should know

Patients should discuss the expected benefits, limitations, risks, recovery and orthodontic requirements before deciding on treatment.
