Conservative technique for the removal of implants displaced into maxillary sinus

Resumo

Displaced dental implants into the maxillary sinus are relatively rare. Treatment consists of implant surgical removal. Objective: To present two case reports of the removal of implants displaced into maxillary sinus by a conservative technique. Case report: Report 1: A 44-year-old female sought for treatment complaining about headaches and recurrent sinusitis. In the anamnesis she reported she had been undergone placement of nine maxillary implants, fifteen years ago, with total loss of those elements. At the imaging exams it was possible to observe two displaced implants into the bilateral maxillary sinus, besides radiopaque image on the left maxillary sinus, compatible with maxillary sinusitis. Based on this data, the proposed treatment plan was the removal of the displaced implants through Caldwell Luc approach and sinusotomy in the left side, under general anesthesia. The patient has a follow-up of 6 months without complaints. Report 2: A 42-year-old male was referred to the Surgery and Maxillofacial Traumatology Department for implant removal from the right maxillary sinus. Patient underwent implant installation in the area around 9 months ago. In the computarized tomography it was possible to diagnose the implant migration into the right maxillary sinus. the proposed treatment plan was the removal of the displaced implant via Caldwell Luc Access by repositioning the bony window and sinusotomy. Results: Patient has been with no complaints at 30 days after surgery. Conclusion: The technique has been shown to be effective in treating the condition.
