Abstract

Actinomyces species are members of normal oral flora that may give rise to a rare disease???oral actinomycosis. Presented herein is a case of early implant failure associated with actinomycosis in an otherwise healthy 43-year-old female and the treatment adopted after explantation. Clinically, 1 month after the implant placement, the peri-implant soft tissues were hyperplastic and associated with an excessive tissue reaction, bleeding, suppuration, deep probing depth, and implant mobility of #19 and #20 implants. Both implants were removed and all granulomatous tissues were thoroughly debrided. Histopathological examination revealed signs of acute ulcerative inflammatory reaction and Actinomyces colonies. The patient was prescribed short-term oral penicillins. Six months after explantation, the deficient bone was augmented using a combination of absorbable collagen membrane, autogenous block bone, and xenograft. The patient was followed for 1 year; and subsequently, 2 implants were re-inserted at the same positions. The patient was followed and no recurrences were observed. Implant failure due to actinomycosis is an extremely rare condition, and a definitive diagnosis is therefore essential for successful treatment.
