We encountered a case of secondary infection associated with a silicon implant in the mental region. A 41-year-old woman underwent plastic surgery with silicon implantation in the mental region 12 years previously.
Recently, she had periapical periodontitis of the mandibular anterior teeth. She was cured by endodontic treatment by her dentist. Secondary infection of the silicon implant arose from the periapical periodontitis, and she was referred to our department. An abscess and an extraoral fistula were observed in the mental region. The silicon implant was removed surgically after resolution of infection.
In the oral and maxillofacial region, silicon implants often cause secondary infection triggered by dental infection.
This case suggests that oral hygiene and oral care are essential to prevent secondary infections derived from odontogenic infection.
