There have been several case reports about a formation of orocutaneous fistula associated with odontogenic or implant infection. This case is about a rapid formation of an orocutaneous fistula, which hardly can be seen, only 7 days after implant placement with sinus floor elevation via transalveolar approach. It was completely healed after incision and drainage, followed by administration of suitable antibiotics without removal of implant fixture. Trauma during the operation and opportunistic infection by normal oral flora might be the cause of the fistula. It is important to maintain an aseptic environment before and during an operation with minimal invasive approach for prevention of complications including an orocutaneous fistula.
