When you use the term 'jaw implants', I assume you are specifically referring to jaw angle implants as opposed to a chin implant. Jaw angle implants are the hardest facial implants to surgically place correctly if not done by someone with a lot of experience. They are prone to asymmetries in position as well as undesired aesthetic improvement if not properly presurgically planned. Thus, they have the highest rate of revision of all the facial implants. In some cases, what patients seek from jaw angle augmentation can not be achieved by standard implants and are best done with custom-designed implants. (e.g., the straight jawline from chin to angle) They do not have a higher infection rate than other facial implant sites however.
