Chin implants are usually made of a silastic (silicone) material and are available in two forms: as a gel within a bag, or as a solid block which is either preformed or contoured to each individual need. Acrylic implants may also be used.
Implant surgery usually takes approximately 30 minutes, and is performed under a local anesthetic. After rinsing the mouth with an antiseptic mouthwash, an incision is made in the depression between the lower lip and the external gums of the lower teeth. A pocket is then created between the lining of the bone and the muscle and fat covering the chin. The size of the pocket is determined by the structure of the face and the esthetic goals. An implant to fit the pocket is then put in place and the incision is closed. The advantage to this procedure is that there is no external scar.
In the past, the incision was made in the natural crease under the chin. Although the scar was somewhat hidden in the crease, it was still visible. This is why entering through the mouth is now preferred. Once the procedure is complete, a light pressure dressing is applied to control swelling and bruising. The dressing is removed within 2 days.
For comfort, a soft diet is recommended until the dressings are removed. Hot foods should also be avoided because the area tends to be numb for some time after the surgery and there is a risk of scalding the lower lip.
