Abstract
Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry. The displacement of dental implants into the sinus membrane, a complication related to the maxillary sinus, is one of the most common accidents reported in the literature. The treatment for this complication is the surgical removal of the implant. A 60-year-old woman with three dental implants displaced into the maxillary sinus (one implant displaced into the left maxillary sinus and two implants displaced into the right maxillary sinus) underwent surgery for removal of the implants. The surgery to remove the implants was performed under local anesthesia through the Caldwell-Luc technique. The patient was subsequently administered antibiotic, anti-inflammatory, and analgesic drugs. The patient returned 7 days after the surgery for suture removal and is being regularly monitored to determine whether future rehabilitation of the edentulous area is necessary. In conclusion, surgical removal of the dental implant displaced into the maxillary sinus is the treatment of choice. This technique is appropriate because it allows the use of local anesthesia and provides direct visualization for the removal of the implants.
Highlights
Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry and is generally considered a safe surgical procedure with a high success rate
The surgical technique used in this study was to remove the implants using the CaldwellLuc approach, which requires the removal of a bone window of the lateral wall of the maxillary sinus for a direct approach to this cavity [7]
The authors classified the sinonasal complications resulting from dental treatment and suggested functional endoscopic sinus surgery (FESS), implant removal, or oroantral communication (OAC) repair for treatment of the implant dislocation with sinusitis
Summary
Oral rehabilitation with dental implants has become a routine treatment in contemporary dentistry and is generally considered a safe surgical procedure with a high success rate. As with other surgical procedures, this type of surgery can lead to complications, which should be taken into consideration. The implant complications related to surgery include hemorrhage, neurosensory disorders caused by nerve injury, damage to adjacent teeth, mucoperiosteal flap dehiscence, and exposure of bone and implant. Complications involving the maxillary sinus include perforation of the sinus membrane, bleeding from the sinus cavity, displacement of implants or other materials into the maxillary sinus, and postoperative sinusitis [2]. One of the most likely areas for transsurgical complications is the posterior maxilla. This region is characterized by soft bone with no cortical portions and a large trabecular portion, which will probably destabilize the implant and could cause it to fail. The resorption of the alveolar ridge, sinus pneumatization, and inflammatory reaction in the peri-implant tissues may promote the displacement of the implant into the sinus cavity [3]
