Abstract:

Background: Maxillary sinusitis has been considered as a major complication during sinus elevation surgery. Case report: This case report presents an implant failure, persistent sinusitis and extraction of natural tooth that are caused by odontogenic infection during. A patient was treated with the simultaneous sinus elevation and dental implant placement for rehabilitation of the maxillary molar, which is adjacent to a natural tooth with intact root canal filling. Four months later, maxillary sinusitis was diagnosed reflected by nasal obstruction and foul-smelling discharge. The mobile implant was removed and replaced by a short implant without sinus elevation surgery. However, repeated symptoms of sinusitis was observed, which immediately healed after the extraction of natural tooth. Then the patient received implant insertion in the region of missing tooth, and no further complications were observed. Conclusion: We proposed that sinus elevation stimulate the colonization of bacteria from the adjacent endodontically treated tooth, which lead to sinusitis and extraction of both implant and natural tooth.
