Clinical treatment of postoperative infection following sinus augmentation.

PURPOSE: The aim of this case report is to present the successful clinical treatment of two cases of postoperative infection following maxillary sinus augmentation.

METHODS

In the two cases of postoperative infection, immediate total removal of the grafted material from the sinus was conducted to stop the spread of the infection, after which a high dose of antibiotics was administrated. Re-augmentation procedures were then conducted after the infection subsided.

RESULTS

No further complications occurred after sinus re-augmentation. The dental implants placed in the re-augmented sinus were clinically osseointegrated, and the implant-supported restorations in the two cases of postoperative infection have been functioning very well for over 2 years.

CONCLUSIONS

In the case of infection of the grafted sinuses, it is necessary to completely remove the graft materials and then administer a high dose of antibiotics to treat the acute infection, after which sinus re-augmentation is suggested.
