Are you concerned about having a small jaw and the balance of your profile? Does your mouth look like it sticks out? Or do you want to achieve a sleeker, more defined jawline?
Chin contouring is a procedure that improves the appearance of your profile and jawline by adjusting the shape and position of the tip of your chin.
By selecting the most appropriate method based on the size of the jaw, the degree of recession, and your desired outcome, we aim to achieve a well-balanced profile that takes the E-line into consideration.

Do you have any of these concerns regarding your jaw?
- ✓ I have a small jaw and am concerned about the balance of my profile
- ✓ I want to make my jawline look more defined
- ✓ I want to refine my E-line
- ✓ My mouth looks like it's sticking out
- ✓ I want to naturally bring my chin forward
If the tip of the chin is small or set back, the mouth may appear to protrude relatively far forward when viewed from the side, and you may be concerned about the balance of your jawline.
In such cases, chin augmentation—which adds height and forward volume to the tip of the chin—may improve the appearance of the profile and the mouth area.
However, concerns about the jawline aren’t always caused solely by the volume of the chin. It’s important to assess your bone structure, the condition of your mouth area, and your desired results before determining the most appropriate treatment.
Why R.O. Clinic's Chin Augmentation Is the Top Choice

Chin contouring is a procedure that affects not only the tip of the chin but also the overall appearance of the profile and jawline.
At R.O. Clinic, we recommend treatments tailored to each patient’s bone structure and preferences, using options such as silicone implants, artificial bone, and hyaluronic acid.

- ★Comprehensive After-Sales Support
Custom designs tailored to each individual's body structure
Since the size, position, and shape of the chin vary from person to person, the specific changes required will differ even for those who simply want to “protrude their chin.”
At R.O. Clinic, we assess the current shape of your skeletal structure and chin and determine the extent to which we will adjust it forward or downward.artificial boneNext, we will use the CT data to create a 3D-printed model of the facial bones, and then fabricate the artificial bone to fit that skeletal structure.
An assessment that takes into account the balance of the entire face, not just the profile
When shaping the chin, it is important to consider not only the tip of the chin but also the balance with the nose, mouth, and jawline.
At R.O. Clinic, we don’t focus solely on the tip of the chin; instead, we consider the treatment approach while ensuring harmony with the mouth area and jawline. If it is necessary to adjust the skeletal structure itself—such as the length or protrusion of the chin—a mandibular mentoplasty is one of the options available.

Proposing Surgical Procedures Tailored to Your Needs
There are several methods for chin augmentation, including silicone implants, bone grafts, and hyaluronic acid.
In some cases, osteotomy may be the appropriate option if you wish to adjust the length, width, or position of the bone structure itself. Therefore, we propose treatment methods while taking into account your preferences—such as whether you’d like to “have the area properly corrected through surgery” or “first see the results with injectable treatments.”
Aftercare That Provides Peace of Mind Through the Postoperative Period
When it comes to chin augmentation, downtime and the postoperative recovery process vary depending on the procedure used.
At R.O. Clinic, we continuously monitor your post-operative condition and have established a system that makes it easy to consult with us about any symptoms or concerns regarding your results, providing you with the support you need to feel at ease after your procedure.
Chin Augmentation at R.O. Clinic
The tip of the chin affects not only the profile but also the jawline when viewed from the front and the overall balance of the face. Chin augmentation helps achieve overall facial balance by adjusting the tip of the chin forward or downward and adding volume where needed.
At R.O. Clinic, we take into account the nose, mouth, and jawline to achieve a natural, well-balanced result where the chin itself does not stand out.
Expected Benefits
The following benefits can be expected from chin augmentation:
- Defining the E-Line
- Improving the Balance of Your Profile
- Make Your Jawline Look Sharper
- It gives your mouth a clean, neat appearance
- Can help make your face look smaller
Adding just the right amount of volume to the tip of the chin can help correct the appearance of a receding chin and restore balance to the lower face. Additionally, changing the position and shape of the chin tip can help create a more defined and refined jawline.
However, since the necessary changes vary depending on the patient’s original skeletal structure and jaw shape, it is important to select a treatment method that is appropriate for the condition of the patient’s skeletal structure and jawline.
Cases That Can and Cannot Be Improved Through Chin Augmentation Alone
Concerns such as a small or receding chin can potentially be improved by adding volume with silicone implants or artificial bone.
Silicone implants are an ideal option for those who wish to project the tip of the chin forward and refine their facial contours. You can choose from a variety of implant shapes and select the size that best suits your bone structure and preferences.
Bone grafting is a treatment option that can be used when the goal is to reposition the chin not only forward but also downward.
On the other hand, if you have a long or protruding jaw, or if you want to significantly alter the width of your jaw or the bone structure itself, adding volume with prostheses or artificial bone is not a viable option. In such cases, a mandibular mentoplasty—a procedure that involves cutting and repositioning the bone to reshape the jaw—may be appropriate.

In addition, if you don’t want a major change but would like to adjust the volume of your chin tip through injections, hyaluronic acid is also an option.
Risks and Side Effects
The following are the main risks and side effects associated with chin augmentation.
- Infection
- Hematoma
- Numbness in the Jaw
- Bending or Misalignment of Prostheses and Artificial Bone Grafts
- The possibility that you may not fully experience the changes you hoped for
If an infection occurs, symptoms such as a sensation of heat, redness, severe pain, and swelling at the treatment site may persist for an extended period.
A hematoma is a condition in which blood accumulates inside a wound due to postoperative bleeding. It can cause purple swelling from the jaw to the neck, and if left untreated, it may lead to infection or the formation of a lump, so caution is advised.
In addition, because the procedure involves dissection near the sensory nerves, you may experience numbness in your jaw or gums.
With silicone implants, there is a possibility that they may become bent or displaced due to pressure from the jaw muscles; if you are concerned about their position, corrective measures may be considered depending on the specific circumstances.
At R.O. Clinic, we carefully explain not only the expected results of a procedure but also the risks and post-operative recovery process, and we proceed with the treatment only after you are fully satisfied with the explanation.
Who Should Consider Chin Augmentation?
If you have any of the following concerns, chin augmentation may be right for you.
- For those who are concerned about having a small jaw
- For those who want to refine their E-line (aesthetic line)
- For those who want to improve the appearance of their profile
- For those who want to enhance their facial contours
- For those who want a natural look
In particular, if you are concerned about the balance of your profile or the area around your mouth due to a small or receding chin, chin augmentation can help improve this.
However, the most appropriate treatment varies depending on the size and position of the jaw, your bone structure, and the changes you wish to achieve. It is important to have your condition assessed during a consultation and then consider the treatment method that is best suited for you.
Treatment Methods
R.O. Clinic offers various chin augmentation procedures, including the insertion of silicone implants or artificial bone, as well as hyaluronic acid injections.
Since treatment methods and the scope of adjustments vary from case to case, we carefully consider the desired changes, the patient’s jaw structure, and the necessary volume when selecting a treatment method, with the goal of achieving a natural-looking result.
Silicone Implants
A silicone implant is a procedure in which medical-grade silicone is inserted into the tip of the chin to create a forward projection or refine the facial contour.
During the procedure, an incision of approximately 3 cm is made inside the mouth, and the prosthesis is inserted beneath the periosteum, which covers the bone. Because the procedure is performed through the mouth, it leaves no visible scars on the face.
At R.O. Clinic, we offer implants in a variety of shapes and determine the appropriate size based on the shape of your jaw and your preferences, using preoperative simulations as a guide.
artificial bone
Artificial bone is a method of reshaping the chin using a hydroxyapatite preparation.
At R.O. Clinic, we use a 3D printer to create facial bone models based on patients’ CT data and custom-make artificial bones tailored to that specific skeletal structure in advance. Since this method allows not only for moving the tip of the jaw forward but also for adjusting it downward, it is well-suited for cases where patients wish to refine their facial contours, including the length of the jaw.

During the procedure, an incision of about 3 cm is made inside the mouth, and beneath the periosteum,artificial boneInsert it and secure it in place. Since the artificial bone must be custom-made, a preparation period of about 2 to 3 weeks is required from the CT scan to the procedure.

hyaluronic acid injection
Hyaluronic acid injections are a procedure in which a hyaluronic acid solution is injected into the tip of the chin to adjust its volume and shape.
You can reshape the tip of the chin by adjusting the injection site and volume without the need for an incision; however, since hyaluronic acid is absorbed by the body over time, repeat injections may be necessary to maintain the results.

How to Choose the Right Surgical Procedure for a Patient
When choosing a surgical procedure, it is important to determine in which direction and to what extent the change needs to be made.
If you’re looking for a subtle change, hyaluronic acid is a good option; if you want to add volume to the front of your chin, a silicone implant is a viable choice. Furthermore, if you’d like to adjust the position of your chin forward and downward to match your bone structure, a custom-made artificial bone may be considered.
At R.O. Clinic, we aim to achieve a natural-looking result tailored to your wishes, taking into account the balance with your nose, mouth, and jawline. For cases where skeletal structure makes it difficult to achieve the desired results through volume-enhancing methods, we will recommend the most appropriate treatment, including mandibular mentoplasty.
We strive to provide thorough consultations, so even if you’re unsure which approach best suits your needs, please feel free to contact us for a consultation.
The Procedure for Chin Augmentation
At R.O. Clinic, we provide support through post-operative follow-up visits until your results have fully settled, so you can consult with us if you have any concerns or questions.
Counseling and Medical Examinations
First, we’ll ask you in detail what specific aspects of your chin are concerning you and what level of change you’re hoping for.
During the consultation, we examine not only the tip of the chin but also the nose, mouth, and jawline to assess their balance, and we determine the treatment approach while taking the overall balance of the face into consideration.
Design and Treatment
Based on the results of your consultation and examination, we use 3D simulations to share a visual representation of the expected outcome with you as we design the treatment plan to determine the direction and extent of the adjustments to your chin.
When using silicone implants or artificial bone, an incision of approximately 3 cm is made inside the mouth, and the implant is inserted and secured beneath the periosteum. Since the procedure is performed through the mouth, no scars remain on the surface of the face.
For artificial bone, we create a 3D model of the facial bones based on CT data and fabricate artificial bone tailored to each individual’s skeletal structure.
The procedure time for surgeries involving silicone implants or artificial bone is typically about 40 to 60 minutes.
Postoperative Recovery and Downtime
Swelling and bruising may occur after chin augmentation using silicone implants or artificial bone. While the severity and course of these symptoms vary from person to person, swelling generally subsides gradually over a period of about 3 to 4 weeks.
After the procedure, the tip of your jaw will be secured with tape for 3 days; you can remove the tape yourself starting on the 4th day, though depending on your condition, it may need to remain in place for about a week.
One week after surgery, we will conduct a follow-up examination to check the condition of the incision and the tip of the jaw.
Follow-up
After surgery, it is important to monitor your progress, checking not only the swelling and the condition of the incision but also the position and shape of the chin tip.
At R.O. Clinic, we’ve established a system that makes it easy for you to consult with us about post-operative changes, how to care for yourself, and any symptoms that concern you, and we’ll support you until your results have fully settled. If you have any concerns—such as prolonged swelling, asymmetry, or discomfort regarding the shape or position of your chin—please feel free to contact us.

What You Need to Know to Avoid Regrets After Chin Augmentation

When performing chin augmentation, it is important to consider not only the position of the chin tip but also its harmony with the nose, mouth, and jawline. Since projecting the chin tip too far forward can result in an unnatural appearance, the design must be tailored while taking into account the overall balance of the face.
In addition, silicone implants, artificial bone, and hyaluronic acid differ in terms of the extent to which they can be adjusted, the amount of downtime required, and how long the results last. Choosing a procedure that aligns with your desired results and your bone structure will lead to a more satisfying outcome.
At R.O. Clinic, we carefully assess each patient’s condition and preferences and recommend treatments that take into account the balance of the entire face. If you’re unsure which method is right for you, please feel free to consult with us.
Frequently Asked Questions
Q: Are the results of chin augmentation semi-permanent?
A: The duration of the effects varies depending on the treatment method.
Although silicone implants and artificial bone are not absorbed by the body over time, changes in facial features due to aging may alter one’s appearance. On the other hand, since hyaluronic acid is gradually absorbed by the body, repeat injections are necessary to maintain the results.
Q: What is the difference between silicone implants and artificial bone?
A: Both procedures are designed to reshape the chin, but they differ in the materials used and the fabrication methods. For silicone implants, a suitable size is selected from a range of off-the-shelf products, while artificial bone is custom-made to fit the patient’s bone structure based on CT scan data. Artificial bone can be adjusted not only forward but also downward.
Q: Can hyaluronic acid alone be used to reshape the jawline?
A: In some cases, hyaluronic acid alone can be used to enhance the volume or reshape the chin. However, if significant changes or skeletal correction are needed, silicone implants, artificial bone, or a mandibular mentoplasty may be more appropriate.
Q: Will the scar be noticeable?
A: Since chin augmentation using silicone implants or artificial bone is performed through an incision inside the mouth, there are no visible scars on the face. The incision inside the mouth will gradually heal as the postoperative recovery progresses.
Q: How long is the downtime?
A: When undergoing mentoplasty using silicone implants or artificial bone, swelling and bruising may occur after surgery. Swelling typically subsides gradually over about 3 to 4 weeks; however, since recovery times vary from person to person, be sure to schedule your procedure well in advance if you have important plans.
