A chin implant is a small, solid piece of biocompatible material that a surgeon places over the chin bone to add projection and definition to a weak or recessed chin. The procedure, sometimes called chin augmentation or mentoplasty, is one of the more straightforward facial surgeries, typically performed under general anesthesia with a recovery period of one to two weeks before most people return to work. The average surgeon’s fee is $3,641, though total costs run higher once you factor in anesthesia and facility fees.
How a Chin Implant Works
The implant sits directly on top of the existing chin bone, beneath the soft tissue of the lower face. It doesn’t replace bone or move anything around. Instead, it adds volume and forward projection to create a stronger profile. Because the chin plays a major role in how balanced the face looks, even a small change in chin projection can noticeably affect the appearance of the nose, neck, and jawline.
Chin implants work best for people with mild to moderate chin retrusion, meaning the chin sits slightly behind where it would look proportional to the rest of the face. If the underlying bone structure is sound and jaw alignment is normal, an implant can correct the issue without touching the bone itself. People with subtle facial asymmetry can sometimes benefit too, since the implant contour can compensate for minor differences.
Implant Materials
The three most common materials are silicone, porous polyethylene (often sold as Medpor), and expanded polytetrafluoroethylene (Gore-Tex). Each behaves differently inside the body, and the biggest practical difference comes down to whether the implant integrates with your tissue or stays separate from it.
Silicone implants are solid and smooth. Your body’s tissue never grows into them, which means they can be removed cleanly even 20 years after placement. That reversibility makes silicone the most popular choice. Gore-Tex and Medpor implants, on the other hand, are porous. Over time, your tissue scars into the tiny cavities throughout the implant, essentially locking it in place. This integration provides stability, but it also makes removal significantly more difficult if you ever want the implant taken out or replaced.
Implant Shapes and Sizing
Chin implants come in several shapes, and the choice depends on whether you want a subtle improvement or a more dramatic change to the lower face.
- Anatomical implants mimic the natural contour of the chin bone. They produce a balanced, understated result and are the go-to for people who want improvement without an obviously “done” look.
- Extended anatomical implants cover more of the jawline beyond just the chin point. They enhance both the chin and the lateral jaw, creating a more defined lower face overall.
- Square implants create a wider, more angular chin. These are popular among men looking for a stronger, more masculine jawline.
- Wraparound jaw implants extend along the entire lower jaw from chin to the angle near the ears. These are designed for people who want a comprehensive change to the lower face, not just the chin.
Angular implants produce sharper, more defined lines, while rounded ones create softer curves. Surgeons often have a range of sizes within each shape and will select or customize one based on your facial measurements and goals.
The Surgical Procedure
Chin implant surgery is relatively quick compared to most facial procedures. The surgeon makes an incision in one of two locations: under the chin (submental) or inside the mouth along the lower gum line (intraoral). The submental approach is generally preferred because it carries a lower risk of infection and less chance of injuring the mental nerve, which provides sensation to your lower lip and chin. The trade-off is a small scar under the chin, though it typically fades and sits in a natural crease where it’s hard to notice.
Through the incision, the surgeon creates a pocket directly over the chin bone and slides the implant into position. Once it’s centered and sitting correctly, the incision is closed. Most people receive general anesthesia, though local anesthesia with sedation is sometimes an option.
Recovery Timeline
The first few days after surgery involve the most discomfort. Swelling and tightness around the chin and lower lip are normal. Sleeping at a 45-degree angle for the first several nights helps reduce swelling, and light walking within a day or two of surgery promotes circulation and lowers the risk of blood clots.
Most people return to work within one to two weeks. Swelling and mild discomfort can linger for up to six weeks, though the worst of it subsides well before that. Strenuous exercise, including weightlifting and intense cardio, should wait at least four to six weeks. If the incision was made inside the mouth, you may need to rinse with an antiseptic mouthwash every couple of hours during the first week to keep the surgical site clean while it heals.
The final result isn’t fully visible until swelling resolves completely, which can take a few months. The shape and projection you see at that point is what you’ll have long-term.
Risks and Complications
Chin implant surgery is considered low-risk, but no procedure is without potential complications. The most commonly reported issues include infection, implant displacement (shifting out of position), and numbness in the lower lip or chin. That numbness happens when the mental nerve, which runs along the jawbone near where the implant sits, is irritated or injured during surgery. In most cases the numbness is temporary, but in rare instances it can persist. One documented case involved a patient who developed a nerve growth (neuroma) on the mental nerve after surgery, causing lasting numbness four years later.
Other possible complications include the body attempting to push the implant out (extrusion), gradual erosion of the underlying bone from long-term pressure, and rejection of the implant material. These are uncommon, and the risk drops further with an experienced surgeon who places the implant precisely over the bone.
How Long Results Last
Chin implants are considered a permanent solution. Most patients can expect their implant to last 15 to 20 years or more, and many never need a replacement at all. With proper healing, the implant can remain in place indefinitely without maintenance. The main reasons people eventually have an implant removed or swapped are significant changes to their facial structure over time or a desire for a different size or shape.
Chin Implant vs. Sliding Genioplasty
A chin implant isn’t the only way to augment the chin. Sliding genioplasty is a surgical alternative that involves cutting the chin bone itself and physically repositioning it. It’s a more invasive procedure, but it can address problems an implant cannot: severe chin retrusion, significant facial asymmetry, vertical imbalance (a chin that’s too long or too short), and bite or jaw alignment issues that affect function.
Implants are the better fit when the problem is purely cosmetic and relatively mild. The bone is structurally fine, it just needs more projection. Recovery is shorter, the surgery is less invasive, and the results are reversible if you change your mind. Genioplasty becomes the recommended route when the structural issues go deeper, particularly when jaw function or bite alignment is involved, or when a more dramatic repositioning is needed than an implant can provide.
Cost Breakdown
The American Society of Plastic Surgeons puts the average surgeon’s fee for chin augmentation at $3,641. That number covers only the surgeon’s time. The total bill also includes anesthesia fees, the surgical facility cost, medical tests, post-surgery compression garments, and prescriptions. Depending on the geographic location and the surgeon’s experience, total out-of-pocket costs typically land higher than the surgeon’s fee alone. Chin augmentation is almost always considered cosmetic, so insurance rarely covers it unless it’s part of reconstructive surgery after trauma or a medical condition.
