Harmonization or orthognathic surgery: when each one fits
Quick facts
- Question
- Harmonization or orthognathic surgery
- Central criterion
- Is the concern about bone and bite, or about volume and contour
- Limit of harmonization
- It does not correct malocclusion or a significant bone disproportion
- Who decides
- Oral and maxillofacial surgeon and orthodontist, together with the HOF professional
A patient with a recessed chin, a crossbite or a "concave" profile comes in asking for harmonization. Part of these cases really are about volume and contour. Another part is about bone structure and bite, and the injectable only disguises it, when it helps at all. Recognizing the limit is one of the most important acts of an HOF (orofacial harmonization) professional, and this page helps you decide.
The information is general. The surgical indication belongs to the surgeon, together with the orthodontist, and depends on examinations.
What each approach does
| Approach | Works on | Example of use |
|---|---|---|
| Orthognathic surgery | Position of the jaw bones | Malocclusion, prognathism, significant bone asymmetry |
| Orthodontics | Position of the teeth (and, in children, guidance of growth) | Misaligned teeth, bite |
| Harmonization with fillers | Soft tissue volume and contour | Soften mild retrogenia, balance the chin |
| Botulinum toxin | Muscle (masseter, mentalis) | Modulate contour tied to the musculature |
The essential difference: surgery moves bone; harmonization adds to or modulates soft tissue. When the concern is the position of the bone, harmonization is, at most, a complement.
Signs that the concern is bone-related
Some findings suggest the patient needs an orthodontic and surgical evaluation before any injectable:
- Altered bite: crossbite, open bite, significant overbite.
- Profile with a marked difference between the upper and lower jaw, such as Angle class II or III.
- Marked jaw asymmetry, with chin deviation.
- Joint pain or noise associated with the bite.
- Functional complaint: difficulty chewing or closing the mouth.
In these cases, the HOF professional's role is to recognize and refer. See orthognathic surgery and harmonization and orthodontics and profile change.
When harmonization makes sense
There are cases of mild disproportion in which harmonization helps:
- a slightly recessed chin, with an adequate bite;
- a poorly defined jaw angle;
- a lip-to-chin relationship unbalanced by volume;
- a patient who does not want to or cannot undergo surgery and accepts a compromise result.
In that last case, the conversation must be transparent: the result is cosmetic and does not correct the cause, and the patient needs to know it. See chin surgery or chin filler and harmonization or orthodontics.
Order and coordination
If the patient will have orthognathic surgery, the order matters. The most common sequence is: pre-surgical orthodontics, surgery, stabilization and, only then, harmonization to refine. Placing filler beforehand can get in the way of the assessment and the surgery. The order is decided by the professionals involved. See harmonization and plastic surgery: interval for the coordination logic.
Decision timeline
Harmy and expectations
Harmy simulates volume in areas such as the chin and jawline, which helps show what a filler could do. But the projection uses only the front-facing photo, and the bone profile and the bite do not show. That is why, for patients with suspected malocclusion, the simulation is illustrative and does not replace an orthodontic and surgical evaluation. Use it to talk about volume, never to suggest it solves the bone.
Frequently asked questions
Does harmonization replace orthognathic surgery?
No. Orthognathic surgery corrects the position of the bones and the bite. Harmonization works on volume and contour and can soften a mild disproportion, but it does not solve malocclusion or a significant bone deviation.
When is orthognathic surgery considered?
In general, when there is a malocclusion or a disproportion between the upper and lower jaw that orthodontics cannot resolve, with an impact on the bite, function or profile. The indication comes from the surgeon and the orthodontist.
Harmonization before or after orthognathic surgery?
In general, after the surgery and once things have stabilized, to refine volume and contour. The order should be agreed among the professionals.
Does chin filler fix a recessed chin?
It can improve the look in mild cases, but it does not correct the bone. In significant retrognathia, the path usually goes through an orthodontic and surgical evaluation.
