A stock jaw implant is selected from manufactured sizes and adjusted during surgery. A custom, patient-specific implant is designed from your own CT scan and made for you, so it sits flush against your bone. A stock implant often suits a symmetrical jaw, while a patient-specific implant is usually preferred for asymmetry, larger changes, or revision.

Key Takeaways
- A stock jaw implant uses a ready-made shape, while a patient-specific implant is designed from your own imaging.
- The choice depends on your jaw anatomy, the change you want, and how precisely the implant needs to fit.
- At YOUNIFY Clinic, jaw augmentation starts from THB 90,000 with a stock implant and THB 100,000 with a patient-specific implant.
- Your final price is confirmed in a written quotation after assessment and imaging, before any deposit.
What jaw augmentation changes
Both types of implant are placed on the outer surface of the jaw bone through incisions inside the mouth, so there is no external scar. The difference lies in how the implant is made and how closely it follows your own bone.
How a stock implant works
A stock implant is manufactured in a range of sizes and shapes. Your surgeon selects the one that fits your jaw most closely, adjusts it during the operation, and fixes it in place. Because nothing needs to be designed or manufactured for you, there is no additional wait between planning and surgery.
A stock shape works well where the jaw is symmetrical and the change you want is moderate. Where the change is large, a stock shape can leave a visible step at its edge, because its contour was not made to follow your particular bone.
Side by side
| Stock implant | Patient-specific implant | |
|---|---|---|
| How it is made | Manufactured in a range of sizes and shapes | Designed from your own CT scan and manufactured for you |
| How it fits | Selected and adjusted by your surgeon during the operation | Sits flush against your bone with no gap |
| Usually preferred for | A symmetrical jaw with straightforward anatomy | Two sides that differ, a previous implant that sits poorly, or a large change |
| Edge | A stock shape can leave a visible step where the change is large | The edge is designed to run into your own bone |
| Scheduling | No additional wait before surgery | Several weeks between the scan and the surgery date |
| Starting from (THB) | 90,000 | 100,000 |
Which one suits you
A stock implant is often suitable if:
- Both sides of your jaw are similar in shape
- You would like a moderate increase in width at the jaw angle
- You would prefer not to wait for an implant to be designed and made
A patient-specific implant is usually preferred if:
- The two sides of your jaw differ, and a stock shape would make the difference more visible
- You would like a larger change than a stock shape can deliver smoothly
- You already have an implant that sits poorly and would like it revised
- Your plan includes the chin, and a single continuous lower border is the goal
Your surgeon recommends one or the other after examining you and reviewing your imaging. Neither is right for every face, and a patient-specific implant is not automatically the better choice for a symmetrical jaw that needs a moderate change.
Planning with imaging
Photographs help your surgeon understand the change you are hoping for, but they cannot show what lies beneath the skin. A CT scan of the facial skeleton shows:
- The shape and thickness of the jaw bone, and any difference between the two sides
- The course of the nerves that pass through the jaw and supply sensation to the lower lip and chin
- How the jaw angle relates to the chin, the cheeks, and the rest of the face
Adding the chin
The jaw angle and the chin are seen together. Where the chin is narrow or set back, widening the jaw alone can leave the lower face looking unbalanced. Jaw and chin augmentation can be planned together to create one continuous lower border, or a chin implant or genioplasty can be added to jaw augmentation. Your surgeon explains which combination suits your face.
Implant materials
A stock jaw implant is made of silicone. A patient-specific implant is custom-made for you from your CT scan. Your surgeon explains which material is used for your implant, and why, as part of your consent.
Operation, stay, and recovery
- Hospital: 1 to 2 nights.
- First 48 hours: swelling builds and peaks. Your head is kept raised, with cold compresses and prescribed pain relief.
- First week: swelling is most visible. A soft diet and careful mouth care are needed while the incisions inside the mouth heal.
- Weeks 2 to 4: most patients are comfortable in public. Numbness over the chin and lower lip is common and usually temporary.
- Months 2 to 3: most swelling has resolved and the new contour is visible.
- Months 6 to 12: soft tissue finishes settling over the implant, and this is when the result is judged.
Starting prices
| Procedure | Starting from (THB) |
|---|---|
| Jaw Augmentation - Stock Implant | 90,000 |
| Jaw Augmentation - Patient-Specific Implant | 100,000 |
| Jaw + Chin Augmentation (combined) | 100,000 |
| Chin Implant | 59,000 |
| Genioplasty / Chin Adjustment (with contouring) | 160,000 |
The combined jaw and chin price uses stock implants; a patient-specific jaw implant is priced separately.

A note from our medical team
Patients sometimes assume that a custom implant is always the better option. For a symmetrical jaw that needs a moderate change, a well-chosen stock implant can give a very similar result without the wait. Where the two sides differ, where a previous implant sits poorly, or where the change is large, a patient-specific implant lets us plan the contour on your own scan before the operation, rather than adjusting it during surgery. The CT scan, not the reference photograph, is what tells us which approach fits your jaw.
Frequently Asked Questions
Is a custom jaw implant always better than a stock implant?
Not always. A patient-specific implant is preferred where the two sides of the jaw differ, where a previous implant sits poorly, or where the change wanted is large. For a symmetrical jaw that needs a moderate change, a stock implant is often suitable. Your surgeon recommends one after reviewing your imaging.
Will there be a visible scar?
Jaw and chin implants are placed through incisions inside the mouth, so there is no external scar.
Do jaw implants need replacing?
Facial implants are not routinely replaced on a schedule. They are revised where position, size, or a complication makes revision appropriate, and this is discussed with you as part of consent.
Can an implant placed elsewhere be revised or replaced?
Yes, this is assessed individually. A patient-specific implant is often considered when a previous implant sits poorly, because it can be designed around your current anatomy. Please share any operation notes and previous imaging you have.
Can a jaw implant be removed later?
Yes. Removal is a simpler operation than placement. The bone underneath adapts to an implant over time, so your surgeon will discuss what your jaw is likely to look like afterward before removing one.
