A “sunken” or unnatural chin appearance following chin augmentation is an undesirable cosmetic complication that disrupts facial balance, creating an aged, collapsed look. The good news is that this condition can be completely corrected by removing the old implant and readjusting the new one. This article by Dr Xuan Quan Clinic identifies the exact causes and safe corrective solutions to help you regain a perfectly proportioned V-line chin.
Why does the chin look sunken or unnatural after augmentation?
A sunken or misshapen chin appearance after surgery often stems from the following technical errors:
- Using an excessively thick implant: Incorrect measurements or over-trimming the implant results in a projection that exceeds the natural structure. The chin is pushed too far forward relative to the lips and nose, creating a sunken, aged appearance.
- Incorrect implant placement: Poor pocket dissection technique leads to the implant resting on muscle tissue rather than directly against the jawbone. This causes the implant to shift forward while pulling the lower lip down, exposing the teeth when speaking.
- Incorrect procedure selection: The patient may have a congenital underbite (malocclusion) due to jawbone structure. Attempting chin augmentation instead of orthodontic treatment or corrective jaw surgery only exacerbates the underbite, making the flaw more obvious and severe.

Safe corrective solution for chin implant complications at Dr Xuan Quan Clinic
Issues such as an underbite appearance following chin augmentation (caused by incorrect implant placement or implant displacement) are effectively resolved through a safe corrective procedure:
Procedure: The surgeon performs a dissection via an intraoral incision to remove the old implant and clear the fibrous capsule. Subsequently, a new biological implant – custom-carved to fit the chin bone precisely and securely fixed with a plate – is inserted, or an autologous chin sliding osteotomy is performed, depending on the severity of the condition.
Advantages: Thoroughly corrects underbite or misalignment, restores a natural V-line chin shape, balances facial proportions, and prevents future displacement complications.
Disadvantages: Requires a recovery period (7 – 14 days) and involves a more complex dissection technique compared to the initial surgery.
Suitable candidates: Individuals experiencing complications such as an underbite appearance, misalignment, abnormal protrusion, or fibrous capsule formation following chin augmentation at unreliable facilities.

Important Considerations to Avoid Chin Augmentation Complications
To achieve a perfect V-line chin and minimize the risk of dangerous complications such as misalignment, a sunken appearance, or infection, please pay close attention to the following:
- Choose a reputable aesthetic clinic: Absolutely avoid unlicensed spas or facilities lacking Ministry of Health certification to prevent the risk of wasting money while suffering physical harm.
- Select a highly skilled and qualified surgeon: The procedure must be performed directly by a specialist in maxillofacial surgery who can accurately map proportions and precisely create the pocket for the implant.
- Prioritize premium, authentic implant materials: Opt for materials with high biocompatibility – such as Pureform (ePTFE) – rather than traditional silicone to reduce the risk of implant rejection or capsular contracture.
- Strictly adhere to post-operative instructions: Properly care for the incision site, avoid foods that promote scarring or pus formation (e.g., water spinach, chicken, seafood), take medication as prescribed, and attend the scheduled appointment for suture removal.

FAQs About Correcting a “Sunken” Chin Implant
To help alleviate your concerns and provide a clearer understanding before you decide on revision surgery, Dr Xuan Quan Clinic has compiled and briefly answered the most common questions regarding this issue:
Is the correction procedure painful?
There is no need to worry. Thanks to advanced local anesthesia techniques used prior to the procedure, the process of removing the faulty implant and placing a new one is gentle and causes no pain or discomfort.
How soon can the procedure be corrected?
The optimal time is 1 to 3 months after the initial surgery, allowing the chin tissues to fully recover and stabilize.
However, in cases of severe technical error or signs of infection, you should see a doctor to have the implant removed as soon as possible.
Will the correction procedure leave a scar?
Absolutely not. The doctor skillfully performs the procedure through the original incision – located entirely inside the mouth (or beneath the chin crease) – and closes the wound with specialized cosmetic sutures, leaving no visible surgical marks on the skin.
