Forehead augmentation and foreign materials implanted or inserted.

Forehead is very forgiving area for remodeling either by means of augmentation or reduction. Different materials can be used for purpose of augmentation including your own bone. In the case of larger deformity a custom made Medpore implant may be a good choice. It is not likely that well fitted implant will move; it can be fixed with several screws or plates if needed. Risk of infection is minimal.For small, localized deformities involving bone Artefill (permanent tissue filler) may be used as well as hydroxyapatite granule.

Regardless of the forehead augmentation used, implant settling into the bone is not a issue. This is because the frontal bone is a large surface area and any pressure caused by an augmentation is widely dispersed. Thus what you term as 'bone erosion' is of little concern. I have placed/removed/modified many forehead augmentation/reconstructions and have yet to see this be an observable issue.
