Dislocation of dental implant into the maxillary sinus has been reported and attributed to a number of factors. It is a complication that may occur intraoperatively or postoperatively. The treatment modalities of migrated implants range from a no treatment and follow up approach to surgical intervention to retrieve the dislocated implant. The purpose of this systematic review is evaluating the different treatment modalities reported for addressing this complication. Using the medline and pubMed central databases, this study examined the different treatment modalities and instruments used to address the problem of migrated implant into the maxillary sinus. The results of this research have revealed that sinusitis is the most common reported complication associated with implant migration. Additionally, Caldwell-Luc surgical operation for implant retrieval into sinus was the most common used treatment modality. Furthermore, using surgical aspirator, vascular forceps and endoscope were among the most used instruments employed to facilitate implant retrieval.
