Or, you may get medicine to numb the area, along with a medicine that will make you relaxed and sleepy.</li><li>A cut is made, either inside the mouth or outside under the chin. A pocket is created in front of the chin bone and under the muscles. The implant is placed inside.</li><li>The surgeon may use real bone or fat tissue, or an implant made out of silicone, Teflon, Dacron, or newer biological inserts.</li><li>The implant is often attached to the bone with stitches or screws.</li><li>Sutures are used to close the surgical cut. When the cut is inside the mouth, the scar can barely be seen. </li></ul><p>The surgeon may also need to move some bones:</p><ul><li>You will likely be under general anesthesia.</li><li>The surgeon will make a cut inside your mouth along the lower gum. This gives the surgeon access to the chin bone.</li><li>The surgeon uses a bone saw or chisel to make a second cut through the jaw bone. The jaw bone is moved and wired or screwed in place with a metal plate.</li><li>The cut is closed with stitches and a bandage is applied. Because the surgery is performed inside your mouth, you will not see any scars.</li><li>The procedure takes between 1 and 3 hours. </li></ul><p>Chin augmentation is commonly done at the same time as cosmetic nose surgery (<a test="test" href="./002983.htm">rhinoplasty</a>) or facial <a test="test" href="./002985.htm">liposuction</a> (when fat is removed from under the chin and neck).</p><p>Surgery to correct bite problems (orthognathic surgery) can be done at the same time as chin surgery.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Why the Procedure is Performed</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
