Implante dentário deslocado para seio maxilar, relato de caso de complicação cirúrgica

Abstract

INTRODUCTION: Pneumatization of the maxillary sinus makes it impossible to install dental implants in the posterior region of the maxilla, in addition to being associated with possible displacements of foreign bodies into the maxillary sinus during surgical procedures. These strangers are associated with complications, such as sinusitis and, therefore, removal is mandatory. Thus, some foreign body removal techniques are useful in the literature, such as the Caldwell-Luc technique and the endoscopic technique. OBJECTIVES: The objective of this work is to report a case of removal of

two dental implants displaced to the maxillary sinus using the conservative Caldwell- Luc technique. METHODOS: Male patient, 60 years old previously submitted to

surgery to install dental implants, came to the office complaining of nasal obstruction and frequent headache. Patient reported displacement of two dental implants into the left maxillary sinus and computed tomography by conical beam demonstrated complete veiling of the left maxillary sinus and confirmed the presence of two implants inside. It was planned to remove the implants via the intra-oral route using the Caldwell-Luc technique. Preoperative antibiotics and corticosteroids were prescribed for the treatment. The technique is done through an incision in the bottom of the maxillary vestibule, followed by mucoperiosteal displacement so that there is exposure of the anterior part of the maxillary sinus and then osteotomy in the region, for removal by a foreign body. The patient has been in follow-up for 10 months with no signs of sinusitis. CONCLUSION: The Caldwell-Luc technique proved to be effective and simple to perform removal of foreign bodies from the maxillary sinus. In addition, it made it possible to resolve the symptomatic picture of sinusitis. The present case exemplifies one of the frequent complications due to surgery to install dental implants in the atrophic maxilla region and which the technique adopts is effective and safe.
