INFECTED SILICONE CHIN IMPLANT AFTER IMPLANT-SUPPORTED JAW REHABILITATION: CASE REPORT AND LITERATURE REVIEW.

To report the infected silicone chin implant due to the non-ideal placement of dental implants, in female patient, 67 years old. A patient unsatisfied with her facial profile had installed a silicone chin implant 25 years ago. Recently underwent surgery for the placement of dental implants in a region close to the silicone implant. The non-ideal positioning of the dental implants and close contact with the silicone implant led to the absence of osseointegration, with consequent mobility and infection of both. The silicone implant was removed with dental implant that shows mobility. In the imaging exams could be noted others complications of silicone implant like bone resorption and the formation of a narrow bone layer around the inferior border of implant. Alloplastic implants are an option for the esthetic correction of chin deformities. Solid silicone is biocompatible and highly resistant to degradation, with a minimal allergic reaction and risk of toxicity. However, a number of postoperative complications may arise, such as migration or displacement, extrusion, foreign body reaction, bone resorption, heterotopic bone formation and infection. The precise imaging exams are critical to arrive at a diagnosis and the best treatment plan.
