Jaw Implant Procedure and Management

Implants can strengthen the jawline and create a more balanced facial silhouette by augmenting the mandibular body, angle, and ramus. A wide variety of patients can benefit from this procedure, including those with normal, deficient, or surgically altered anatomy.

Normal dimensions

Most patients who desire mandible augmentation have lower face horizontal dimensions that relate to the upper and middle thirds of the face within a normal range.

These patients, usually males, perceive a wider lower face as desirable. This group benefits from implants designed to augment the ramus and posterior body of the mandible and, in so doing, increase the bigonial distance.

Other patients desire more definition and angularly to the mandibular border.

Implants which augment the anterior mandible back to the ramus can achieve this.

Skeletal deficiency

Another group of patients who benefit from mandible augmentation are those with skeletal mandibular deficiency.

The majority of these patients (approximately 80 percent) can have their Class II (overbite) dental relationships normalized through orthodontic tooth movement.

The remaining 20 percent, or 1 percent of the total population, have mandibular deficiency that is so severe that surgical mandibular advancement would be needed to correct it.

For these patients with corrected occlusion, alloplastic augmentation of the mandible can provide a visual effect similar to, and, in my opinion, superior to that of sagittal osteotomy with advancement employing an outpatient surgical procedure that avoids any further dental manipulation.

The anatomy associated with mandibular deficiency, which can be camouflaged with implants, includes the obtuse mandible angle with steep mentocervical angle, as well as the decreased vertical and transverse ramus dimensions.

The addition of an extended chin implant will camouflage the poorly projecting chin.

Surgically altered anatomy

A third group of patients who may benefit from alloplastic augmentation of the mandible are patients who have had their Class II dental malocclusion due to mandibular deficiency corrected by sagittal split osteotomy with advancement of the distal segment.

It inevitably creates a contour irregularity at the site of the body osteotomy and distal segment advancement. may also result in an aesthetically displeasing position of the ramus angle with insufficient height, insufficient width, or asymmetry.

Mandible implants, often combined with chin implants can be used to improve contour in these patients. Clinical examples of these uses for mandible implants are shown below.

Implants which augment the lateral mandible can increase the width of the lower face in patients who desire a stronger look to their jaw.

Two examples of patients who underwent mandibular (jaw) augmentation to increase the width of their lower face are shown below.

Facial implants are specially formed solid materials compatible with human tissues, designed to enhance or augment the physical structure of your face.

The precise type and size of facial implants best suited for you requires an evaluation of your goals, the features you wish to correct, and your surgeon’s judgment.

If you are bothered by a small chin, weak jaw, or lack of facial contour, plastic surgery with facial implants may benefit you.

While any area of your face can be augmented with implants, the cheek or malar area, chin, and jaw are the most common sites for facial implants.

Chin implants

Chin implants can increase the size and projection of a chin that is not in proportion with the forehead and mid-face.

A small or recessed chin can also be described as one that seems to disappear into the neck of an individual of normal weight, rather than appearing as a distinct facial feature.

Jaw implants

Jaw implants increase the width of the lower third of your face.

Much like the chin, a weak jaw can be thought of as one that is not well defined and distinct from the neck or one that slopes rather than angles from the ear to the chin.

In some cases, both the chin and jaw can contribute to facial imbalance.

Cheek implants

Cheek implants increase the projection of the cheekbones. They add volume to areas that may be recessed or flat.
