Common Questions This Guide Answers

1. What is orthognathic surgery and how does it differ from orthodontics? → Orthodontics moves teeth within bone; orthognathic surgery moves the bone itself — it is indicated when skeletal discrepancies are too severe for braces or aligners to resolve
2. What conditions qualify a patient for orthognathic surgery? → Overjet ≥ 5 mm or negative overjet, molar differences ≥ 4 mm, open bite > 2 mm, transverse discrepancy ≥ 4 mm bilaterally or ≥ 3 mm unilaterally, severe facial asymmetry, obstructive sleep apnoea with skeletal contributors, and TMJ dysfunction linked to skeletal imbalance
3. What does the treatment timeline look like? → Pre-surgical orthodontics takes 6–18 months, surgery follows, then post-surgical orthodontic finishing — mean total treatment time is up to 36 months; most relapses occur within six months of surgery

Smile Solutions Orthognathic (Jaw) Surgery Melbourne: Who Needs It, What It Corrects & What to Expect

If you've been living with a significant jaw discrepancy, chances are you've adapted to it so gradually that you may not fully recognise the toll it's taking. You might have adjusted the way you chew, the way you speak, or even how you hold your head — small compensations that add up over time. Difficulty biting through food, persistent jaw pain, disrupted sleep, and self-consciousness about your profile are not minor inconveniences. They are the measurable, documented consequences of a skeletal imbalance that no amount of orthodontic treatment alone can resolve. At Smile Solutions — Melbourne's multidisciplinary dental and oral surgery facility — you'll find precisely this level of integrated, experienced care.

Orthognathic surgery — from the Greek orthos (straight) and gnathos (jaw) — is the surgical repositioning of the maxilla (upper jaw), mandible (lower jaw), or both, to correct skeletal discrepancies that sit beyond the reach of braces or aligners. It is among the most transformative procedures in oral and maxillofacial surgery: one that restores function, improves airway health, resolves associated pain, and produces lasting facial balance. It is also one of the most misunderstood — frequently dismissed as cosmetic when, in the majority of cases, it is medically necessary.

This article explains who needs orthognathic surgery, what conditions it corrects, how the diagnosis is made, and what your treatment pathway looks like — with a particular focus on the collaborative orthodontist–oral surgeon model that sets Smile Solutions Melbourne apart.

What is orthognathic surgery and why is it distinct from orthodontics?

Combining orthognathic surgery with orthodontic therapy is a crucial approach for correcting severe dentofacial deformities that orthodontics alone cannot address. This distinction is clinically precise, not a matter of preference. Braces and aligners move teeth within the bone. Orthognathic surgery moves the bone itself.

Among available treatment options, orthognathic surgery is often considered the last resort — typically reserved for cases where the skeletal discrepancy is too severe to be corrected by orthodontics alone, or when the patient is no longer growing and cannot undergo growth modification.

Orthognathic surgery allows oral and maxillofacial surgeons to resolve jaw asymmetry issues and restore function, aesthetics, and balance. The two primary surgical techniques are the Le Fort I osteotomy for repositioning the maxilla and the bilateral sagittal split osteotomy (BSSO) for the mandible.

Certain skeletal discrepancies may persist despite routine growth modification and camouflage treatment, or they may not qualify for these treatments at all. These are addressed through procedures such as the Le Fort I osteotomy and the BSSO.

For a detailed comparison of which conditions can be managed with orthodontics alone versus which require surgery, see our guide on Jaw Surgery vs. Orthodontics Alone: How to Know Which Treatment Your Bite Actually Needs.

Who needs orthognathic surgery? The four core skeletal conditions

1. Anteroposterior discrepancies: overbite, underbite and overjet

The most common indication for orthognathic surgery is a significant front-to-back mismatch between the upper and lower jaws. This shows up as either a Class II malocclusion (retrognathic mandible, excessive overjet) or a Class III malocclusion (prognathic mandible or retrognathic maxilla, negative overjet or underbite).

Class III malocclusions — which can involve mandibular prognathism, maxillary retrognathism, or both — are among the most difficult maxillofacial deformities to correct because of unfavourable mandibular skeletal growth. The condition affects 7.04% of the population overall, and research shows that 63–73% of Class III cases are skeletal in origin. The resulting concave facial profile reflects an imbalance in mandibular and maxillary growth rather than a dental problem that braces can fix.

The clinical threshold for surgical intervention is well established. Patients are indicated for orthognathic surgery when skeletal discrepancies exceed two standard deviations from normal values — typically: overjet ≥ +5 mm or negative overjet; molar relationship differences ≥ 4 mm; anterior or posterior open bite > 2 mm or deep overbite with soft-tissue impingement; transverse discrepancies ≥ 4 mm bilaterally or ≥ 3 mm unilaterally; and facial asymmetries beyond normative thresholds.

2. Vertical discrepancies: open bite and deep bite

Anterior open bite — where the upper and lower front teeth don't make contact when the back teeth are closed — is a complex skeletal condition with real functional consequences, including difficulty biting food and altered speech.

Its aetiology involves skeletal, dentoalveolar, and functional components, and its prevalence has been reported anywhere from 2.9% to 17%. In one retrospective series of 1,095 orthognathic patients, anterior open bite was diagnosed in 11.5% of cases, consistent with the upper range of previous reports.

3. Transverse discrepancies: crossbite and narrow maxilla

When the upper jaw is narrower than the lower jaw, a posterior crossbite results — teeth on one or both sides bite inside rather than outside the lower teeth. In skeletally mature adults, the midpalatal suture has fused, so orthodontic expansion alone is insufficient. At skeletal maturity, a maxillary transverse discrepancy can be corrected through surgically assisted rapid palatal expansion (SARPE), orthodontic dental compensation, or a multipiece Le Fort osteotomy.

4. Facial asymmetries

Asymmetries involving jaw deviation, chin point displacement, or unequal vertical facial heights are among the most functionally and psychosocially significant presentations. The causes are multifactorial — genetic, functional, and environmental factors during growth all play a role — and reported prevalence ranges from 11% to 37% in the general population, rising to 21–67% in people with malocclusions, particularly Class III.

Mild asymmetry can often be managed orthodontically. Severe skeletal deviations generally require surgery.

Beyond the bite: additional medical indications for jaw surgery

Orthognathic surgery isn't solely about occlusion. The American Association of Oral and Maxillofacial Surgeons (AAOMS, 2023 edition) explicitly recognises that surgery may also be indicated where there is documented airway dysfunction such as sleep apnoea, temporomandibular joint disorders, psychosocial disorders, or speech impairments.

Obstructive sleep apnoea (OSA)

Maxillomandibular advancement (MMA) — an orthognathic procedure that advances both jaws simultaneously — is among the most effective surgical interventions for moderate-to-severe OSA, particularly in patients with identifiable skeletal contributors to airway collapse. MMA carries a success rate of approximately 85% and is especially indicated in patients with craniofacial anomalies such as mandibular retrognathia or maxillary hypoplasia who are intolerant of or non-adherent to CPAP therapy.

The outcomes data are compelling. Mean postoperative changes in the apnoea–hypopnoea index (AHI) after MMA were −47.8 events/hour, a mean reduction of 80.1%, and 512 of 518 patients (98.8%) showed improvement.

Temporomandibular joint (TMJ) disorders

Severe skeletal malocclusion is associated with elevated TMD prevalence. Patients with skeletal Class II dentofacial deformity referred for orthognathic surgery show higher rates of TMD, with muscular and degenerative disorders being the most common diagnoses. Correcting the underlying skeletal imbalance can meaningfully reduce TMJ symptom burden — though the relationship is complex and not all TMJ presentations are appropriate for orthognathic surgery. See our guide on TMJ Disorder & Jaw Surgery: When Conservative Treatment Fails and Surgery Becomes the Answer for a detailed discussion of this distinction.

How jaw growth imbalances are diagnosed

Orthognathic surgery planning integrates clinical examination, three-dimensional imaging, and digital surgical simulation. A diagnosis of surgical-level skeletal discrepancy is not made on appearance alone — your specialists at Smile Solutions will work through a comprehensive diagnostic process to build a complete picture of your individual needs.

Diagnostic records required for surgical planning

Patients are eligible for orthognathic surgery if they present with a dento-maxillofacial deformity requiring surgical correction — including skeletal Class II or Class III malocclusion, vertical maxillary excess or deficiency, or transverse discrepancies not manageable with orthodontics alone — have completed or are scheduled to complete presurgical orthodontic treatment, and are in good general health with no systemic contraindications to general anaesthesia.

The AAOMS (2023) also notes that these indications establish the clinical basis for surgery rather than functioning as absolute criteria. Patients who don't fall two or more standard deviations outside published norms may still legitimately require surgery when functional impairment is documented.

Age and timing: when is the right time for jaw surgery?

Orthognathic surgery is generally deferred until skeletal growth is complete — typically 17–18 years for females and 18–21 years for males — to prevent relapse from ongoing jaw development. Children with atypical growth patterns can undergo growth modification early; adults don't have that option and frequently need surgery instead.

Limited research suggests surgery may be performed as early as 16.5 years in males, where circumpubertal growth is complete or nearly so, though continued mandibular growth remains possible until age 20.

The most common age range for orthognathic surgery patients is 15–24 years. A 10-year retrospective analysis of 1,095 cases found the most prevalent age range to be 16–24 years, with a female majority (60.5%) and a mean age of 23.07 ± 5.6 years.

The literature indicates that aesthetic concerns drive more women and younger patients to seek surgery, while men tend to present primarily for functional reasons. Older patients are often more hesitant due to concerns about surgical risk. Whatever your age or motivation, your Smile Solutions team will take the time to understand your specific circumstances and guide you toward the most appropriate timing for your treatment.

The role of pre-surgical orthodontics: why your bite gets worse before surgery

One of the most counterintuitive aspects of orthognathic treatment is the pre-surgical orthodontic phase — and it's something your care team will explain thoroughly so you know exactly what to expect. Before surgery, your orthodontist must "decompensate" your teeth, removing the natural adaptations they've made over years to accommodate the skeletal discrepancy. This temporarily makes your bite look and feel worse. It's a completely normal and necessary part of the process.

In patients with skeletal discrepancies, teeth naturally compensate to allow for a functional occlusion, meaning their inclination and position don't directly reflect the degree of the underlying deformity. Traditional orthognathic planning involves a period of presurgical orthodontic treatment to synchronise the dental deformity with the skeletal deformity by decompensating the teeth. This allows for a planned final occlusion where balanced forces are transmitted across the teeth based on their location within the arch, with the teeth centred correctly within the alveolar housing.

Pre-surgical orthodontics may take as few as 6 months or as many as 18 months, depending on your individual needs. Your orthodontist will typically place braces to align crowded teeth and position them favourably in the jaw.

Once the dental deformity matches the skeletal deformity, surgery is performed, followed by post-surgical orthodontic finishing. Total treatment times — from the start of pre-surgical orthodontics to the end of post-surgical orthodontics — have a mean of up to 36 months.

The surgery-first approach: an emerging alternative

For carefully selected patients, a surgery-first approach eliminates the pre-surgical orthodontic phase entirely, proceeding directly to surgery followed by post-surgical orthodontics. Recent advances in tooth movement mechanics, stability of specific skeletal movements with rigid fixation, and a better understanding of surgery's effects on tooth movement have made this possible, along with surgery-only approaches and the use of clear aligners. In appropriate patients, these protocols can reduce total treatment time, improve quality of life during treatment, and increase patient satisfaction.

Because the baseline occlusion can't guide treatment goals in a surgery-first approach, clinical expertise, accurate prediction of postoperative tooth movements, and precise skeletal assessment are essential. This approach requires a highly experienced surgical team and isn't suitable for everyone — your Smile Solutions specialists will advise you on whether it's a viable pathway for your situation.

The orthodontist–oral surgeon collaboration at Smile Solutions

Orthognathic surgery is, by definition, an interdisciplinary undertaking. The orthodontist's role spans the initial evaluation, presurgical orthodontics, surgical planning, and postsurgical orthodontics — and at each phase, collaboration between orthodontist and surgeon is critical. As the literature puts it plainly: lack of coordination between the orthodontist and the surgeon will lead to a compromised result.

At Smile Solutions, this collaboration isn't a referral arrangement between separate practices. It's a genuinely integrated model where orthodontists, oral and maxillofacial surgeons, and prosthodontists work together within the same multidisciplinary facility in Melbourne's CBD. That means shared treatment planning, coordinated imaging, and consistent communication across a journey that commonly spans two to three years. For patients, this translates into a seamless, personalised experience backed by genuine clinical depth.

The surgical planning phase at Smile Solutions includes virtual surgical simulation using CBCT data, allowing the surgical team to predict skeletal movements, occlusal outcomes, and soft tissue profile changes before a single incision is made. Specific advances over the past twenty years include increasing fidelity with computer-assisted planning, patient-specific fixation, expanding indications for managing upper airway obstruction, and shifts in orthodontic-surgical paradigms.

What does orthognathic surgery actually correct? A clinical summary

Osteotomies of the midface and mandible are used in contemporary craniomaxillofacial practice to address three-dimensional dysmorphology of the maxillomandibular complex, with positive effects on occlusion, facial aesthetics, and airway management.

In practical terms, orthognathic surgery at Smile Solutions can correct:

• Underbite (Class III): Mandibular setback and/or maxillary advancement
• Overbite / excessive overjet (Class II): Mandibular advancement and/or maxillary repositioning
• Anterior open bite: Superior repositioning of the maxilla, counterclockwise mandibular rotation
• Posterior open bite / deep bite: Vertical dimension adjustment via Le Fort I impaction or advancement
• Crossbite / narrow maxilla: Multi-piece Le Fort I osteotomy or SARPE
• Facial asymmetry: Differential jaw repositioning to equalise vertical and transverse facial dimensions
• Obstructive sleep apnoea (skeletal contributors): Maxillomandibular advancement to enlarge the posterior airway space

Bimaxillary surgery — involving both jaws simultaneously — was the most prevalent procedure in a 10-year retrospective analysis of 1,095 cases, reflecting how often combined maxillary and mandibular discrepancies require coordinated correction.

Outcomes: what the evidence says about results and quality of life

The outcomes literature for orthognathic surgery is extensive and consistently positive — and at Smile Solutions, staying current with the best available evidence is central to how your care team builds your personalised treatment plan.

Orthognathic surgery produces improvements in quality of life both physically and psychosocially, and is associated with high rates of patient satisfaction. It corrects skeletal and dental misalignments, enhancing function and appearance across multiple dimensions in patients with significant dentofacial deformities that orthodontics alone cannot address.

A cohort study of 50 orthognathic patients found high levels of satisfaction with both functional outcomes and facial aesthetics, with objective measurements also showing significant improvements in occlusion and facial balance.

Long-term stability is a key consideration in treatment planning. Recurrence is a recognised feature of the post-surgical course, occurring most frequently within six months of the operation and almost always within a year. This makes committed post-surgical orthodontic follow-through — and experienced surgical technique — essential to durable results.

Key takeaways

• Orthognathic surgery corrects skeletal jaw discrepancies, not dental ones. It is indicated when the underlying bone relationship is too severe for orthodontics to manage, typically when discrepancies exceed two standard deviations from published skeletal norms.
• The four primary indications are anteroposterior discrepancies (overbite/underbite), vertical discrepancies (open bite/deep bite), transverse discrepancies (crossbite), and facial asymmetry, with additional indications including obstructive sleep apnoea and TMJ dysfunction.
• Pre-surgical orthodontics (6–18 months) is a standard component of the conventional treatment pathway. It decompensates the teeth before surgery and temporarily worsens the bite appearance — a normal and expected part of the process.
• Treatment is a collaboration between orthodontist and oral surgeon across multiple phases: initial evaluation, presurgical orthodontics, surgical planning, surgery, and post-surgical orthodontic finishing. Lack of coordination between these roles compromises outcomes.
• Evidence consistently shows high patient satisfaction and measurable quality-of-life improvements across physical, functional, and psychosocial domains following orthognathic surgery.

Conclusion

Orthognathic surgery occupies a precise and irreplaceable position in treating dentofacial deformity. It isn't a cosmetic shortcut, nor is it an extreme last resort for unusual cases — it is the appropriate, evidence-based treatment for skeletal jaw discrepancies that cannot be resolved by moving teeth alone. For patients who have spent years adapting to a jaw relationship that impairs their chewing, their sleep, their speech, or their sense of self, it can be genuinely life-changing.

The complexity of the treatment — spanning years, multiple disciplines, and a hospital-based surgical procedure — makes the choice of provider as important as the decision to proceed. At Smile Solutions Melbourne, the integration of board-registered oral and maxillofacial surgeons with specialist orthodontists under one roof is not incidental. It is the clinical architecture that makes safe, coordinated, and predictable outcomes possible.
