Genioplasty is surgery to change the shape, position, or projection of the chin. A sliding genioplasty moves part of the chin bone and secures it in a new position. Chin augmentation may instead use an implant. The choice depends on the patient's anatomy and the change being sought.
read more about genioplasty ...Genioplasty may address a chin that appears recessed, prominent, or uneven. It may also be part of reconstructive treatment after an injury or for a structural difference. A surgeon assesses the chin, jaw, and bite before recommending a procedure. Chin surgery alone does not correct every problem involving tooth or jaw alignment.
The surgeon makes an incision inside the mouth or, for some implant procedures, beneath the chin. In sliding genioplasty, the surgeon cuts and moves part of the chin bone, then fixes it with plates and screws. In implant surgery, the surgeon positions an implant over the chin bone. The incision is closed after the surgeon checks its placement.
Swelling, bruising, and soreness can occur for several weeks. Patients may need soft foods for a short period, particularly when the incision is inside the mouth. The surgeon provides instructions for oral hygiene, incision care, and activity limits. Recovery varies according to whether bone was moved or an implant was placed.
Risks include bleeding, infection, poor healing, and complications related to anesthesia. Tingling or numbness in the lower lip or chin may occur. An implant can shift or cause other implant-related problems, while plates and screws can cause hardware concerns after bone surgery. A surgeon should explain the risks of the specific technique being considered.
Not always. Genioplasty can involve moving the chin bone, while an implant adds projection without moving that bone.
Yes. Sliding genioplasty can reposition the chin bone forward, backward, or sideways according to the surgical plan.
Chin surgery primarily changes chin position or shape rather than tooth alignment. A surgeon should assess bite concerns to determine whether jaw treatment is also needed.
Yes. Numbness or tingling in the lower lip or chin can occur and may be temporary or persistent.
