A well-defined jawline has become a recognized aesthetic facial skeletal feature, particularly amongst men. An appealing male jawline has a strong chin, jaw angles that are more square with a slight outward flare and a continuity between the front and back of the jaw, creating a wrap-around effect that flows smoothly around the arc of the jaw. While such a male jawline has probably always been desireable through the ages, it has acquired a lot more attention recently due to new techniques and implants that make it surgically possible to alter or create one.
While most male jawline augmentations can be done with conventional off-the-shelf implants, certain jawline deficiencies and aesthetic desires can not be ideally treated this way. Vertical lengthening of the jawline is a good example where standards implant can not create this dimensional change. Certain styles of jaw angle implants do provide some vertical lengthening but no chin implant does so. Traditional chin and jaw angle implants, which come in many different styles, do not connect across the body of the mandible which disrupts a smooth jawline look.
Custom jawline implants are designed off of a patient’s jaw or mandibular model. This is obtained by first getting a 3-D CT scan of their lower jaw. This can be done at almost any facility, hospital or free standing, that offers CT services. The CT scan is done with 1mm cuts which is standard for 3-D reconstructions. The scan data is then sent to a model manufacturer. I currently use Medical Modeling (Golden, Colorado) who makes great models with a rapid turnaround time. Such models can be made either opaque (osteoview) or with clear acrylic where the intrabony structures can be seen. (clearview) For implant designing, the opaque osteoview model is just fine and comes at a lower cost.
The jaw model is then used to make the chin and jaw angle implants. While it is often thought that such implants are made using a computer or CAD-CAM technology, such is not the case. No computer or technician can know what is the best design for the patient’s need or, more importantly, whether any implant design can actually be made to fit into the patient. Computer design works well in reconstruction when there is a facial deficiency on one side and it is normal on the other. Then the computer has a well-defined implant design goal to match. But in aesthetic implant designing, the end target is not as clear and requires the aesthetic judgment of the surgeon. This is why I custom design and fabricate them myself out of modeling clay. These shapes can be shared with the patient for their input as well. Once the final clay implant models are completed, they are allowed to cure and covered with a varnish finish.
The custom-designed jaw implants and the model are then sent to an implant manufacturer. The only material that can be used to make custom implants is silicone. This is because it is a liquid composite that can be poured into a mold and allowed to set. The clay implants are used to make a mold into which the silicone is poured. Other implant materials, such as medpor, would have to be machined which would not only would be a lot more expensive but its manufacturer does not currently offer that service. The final implants are sent back to me for surgical insertion.
Custom jawline implants can be designed and available for surgery in as little as three weeks after a patient acquires their 3-D CT scan. The cost of this custom facial implant process is $3500 to $7500 depending upon how many implants are needed. Surgical placement costs are in addition to the implant fabrication process. While only a minority of male jawline enhancement need custom implants, the final aesthetic results are far superior to trying to use or modify existing off-the-shelf facial implants.
