It is possible to have a chin implant after having Artefill to the same area. The chin implant is placed on top of the bone and the Artefill is injected into the soft tissue above the bone, so they are in different layers. There may be an issue with the timing of placing your chin implant though. I would recommend waiting at least two months after the Artefill was placed before having the chin implant. This should allow the full effect of the Artefill to be seen before having the implant placed.
