Atraumatic tooth extraction by means of piezosurgery in the treatment of ectopic eruption in the maxillary sinus: case report

Ectopic tooth eruption can result due to pathological process, developmental disorder or iatrogenic activity. Ectopic dental elements can be found in the palate region, maxillary sinus region, mandibular condyle, coronoid process, orbital and nasal cavities. The justification for this study is due to the fact that failure to treat unerupted dental elements can lead to external resorption of adjacent teeth, aesthetic problems, shortened dental arches and increased formation of follicular cysts and recurrent infections. In this context, the objective of this study is to carry out a case report of treatment of an ectopic dental element in the maxillary sinus region by means of piezosurgery. Female patient, 16 years old, came to the dental office with pain complaints. On clinical examination, it was possible to observe the absence of dental element 13. In imaging studies, it was possible to observe an ectopic dental eruption in the region of the anterior wall of the maxillary sinus, with part of the dental element included in the sinus. The treatment instituted was surgical removal of the tooth using the atraumatic technique of piezosurgery. Surgical treatment of an impacted element requires osteotomy and odontosection techniques that, by themselves, cause tissue damage. However, piezosurgery-assisted surgery is useful to minimize trauma to the region. It can be concluded that the approach of surgical removal of the ectopic element in the maxillary sinus was satisfactory for resolving the condition. (author)
