Chin implant surgery is typically done for the patient with a weak or retruded chin. In addition to being receded, there can also be a deficiency in regard to width or asymmetry. This may be treated with an implant (solid silicone rubber) placed via an incision placed under the chin or through the mucosa inside the mouth.View Before & After Gallery
The surgery many times is combined with rhinoplasty surgery if facial balance can be improved by addressing the nose and chin at the same time. Other options include an osteotomy(sectioning the bone of the chin) and advancing the bone based on its blood supply. This obviously causes more swelling and healing period than the chin implant and higher risk as to loss of sensation to the chin and lip. Do realize that these chin procedures have no effect on dental occlusion or the way the jaw functions.

Q. Are there different types of chin implants?
A. Yes. The most common are the silicone (solid) rubber implants. The type of implant used is an extended implant that extends from the midpoint of the chin and tapers laterally on the mandible to a position near what above would be the bicuspid tooth. This is a prejowl chin implant and thus improves not only the chin button itself but improves the external appearance and lessens the visiblity of the jowls laterally. It is a significant improvement over the older type small chin button implant that made the jaw appear pointed and did not enhance the overall mandible and also create a better jaw and neckline.
Some implants are made of material that bone can grow into but less optimum for contouring at the time of surgery.
Q. What are the possible risks and complications with chin implants?
- Malposition or displacement. The bony structure of the mandible is the platform upon which the implant is placed. Contouring can accommodate the majority of patients. The patient must also be aware to be cautious during the first 8 weeks regarding inadvertently hitting or traumatizing the chin since this can disrupt healing and result in malposition. Patients with extraordinarily asymmetric chins can have custom made implants , which is more costly but helpful in these cases, but not very often needed.
- Bleeding and infection. Although assumed to be common, it is truly rare in the vast majority of this type of procedure.
- Numbness of lower lip and chin. The nerves that supply the chin , lip and gums comes out of the mandible(lower jaw) in the area of the lower bicuspid teeth. As long as the implant does not impinge on this nerve, is there is any numbness it will be temporary at most. Rarely does this occur if procedure and placement are done properly.
