Placement of implant in close proximity to supernumerary tooth

Ahmad Almehmadi

Abstract


Supernumerary teeth are additional teeth that appear in the maxillary and mandibular arches in addition to the normal set of teeth. The exact cause of the occurrence of supernumerary teeth is unclear, but it is hypothesized to be a result from atavism (the reversion to a primitive dentition), proliferation of remnants of the dental lamina or dichotomy theory, in which the tooth bud is split into two equal or unequal parts: Resulting in two teeth of equal or unequal size. Many complications can be associated with the presence of supernumerary teeth such as crowding, tooth displacement, impaction, delayed eruption of adjacent teeth, esthetic problems, root resorption of adjacent teeth, and the possibility of formation of dentigerous cyst with advanced bone destruction. Management of supernumerary teeth depends on the area and on the presence of pathologic processes around the impacted teeth. Placement of the dental implant to restore an edentulous space requires the presence of adequate amount of bone. Inadequate amount of remaining alveolar bone adversely affects the long-term success of implant placement. In this present study, we report the management of impacted supernumerary central incisor and placement of the dental implant to restore the edentulous space. The patient was not aware of the presence of the impacted supernumerary tooth and reported the loss of his central incisor due to trauma. A multidisciplinary treatment approach was planned including the surgical removal of the supernumerary tooth, bone grafting of the defect, and temporization of the edentulous space. Implant placement was performed after the proper time of healing and the treatment resulted in an esthetically and functionally pleasant outcome.
