Recently, dental implant therapy has been routinely undertaken at many dental hospitals and institutions. Consequently, complications associated with dental implant treatment have also increased.
There is no consensus on the management of bone prosthetic materials displaced into the maxillary sinus following maxillary sinus augmentation surgery (maxillary sinus floor elevation) for a dental implant.
When the displacement of bone prosthetic material into the maxillary sinus occurs, first of all, closure of the perforation between the oral cavity and maxillary sinus should be performed to prevent infection. Next, antibacterial therapy should be administered in conjunction with ventilation and drainage of the maxillary sinus. After the procedure, the bone prosthetic materials displaced into the maxillary sinus will, in most cases, be drained out of the maxillary sinus via the natural ostium.
When intractable maxillary sinusitis occurs following the initial treatment as mentioned above, endoscopic sinus surgery is indicated.
Management of bone prosthetic materials displaced into the maxillary sinus should be performed based on the pathophysiological conditions of the maxillary sinus.
