Implant migration into maxillary sinus: description of two asymptomatic cases.
BACKGROUND
Rehabilitation of edentulous jaws with dental implants has become a usual practice around the world. A very low incidence of complications is associated with this therapy. One of them is migration of dental implants into maxillary sinus. Foreign bodies inside maxillary sinus should be removed because they can cause sinusitis, but if any symptoms are present, preservation alone can be indicated. Implant removal and bone reconstruction on the same procedure reduce treatment time and allow rehabilitation with implant-supported prosthesis.


METHODS
In the present study, we report two cases of dental implants displaced into maxillary sinus that receive different treatment.


RESULTS
In one of them, implant removal and sinus lift were carried out on same procedure while on the other preservation alone was advocated.


CONCLUSIONS
Both treatment modalities treatments allowed installation of implant-supported prosthesis.
