Treatment of Space Loss Caused by Submerged Mandibular Second Primary Molar

Abstract

Submersion is a clinical term describing a tooth depressed below the occlusal plane. In this case report, we present treatment of a patient who had totally submerged primary maxillary second molar, which caused impaction of the second premolar and space loss in the maxillary arch due to tipping of adjacent teeth. A 19 yr old female was referred to the Department of orthodontics. Intraoral examination revealed left mandibular second primary molar was localized lingually being almost covered by gingiva and adjacent teeth inclined closing the space of the related tooth completely. Panaromic radiograph demonstrated that mandibular second premolar was impacted. Based on clinical and radiographic findings mandibular primary second molar was extracted. A pre- Adjusted Edgewise appliance (MBT prescription 022” slot) was used for creating space for the impacted second premolar. Eruption began spontaneously 6 months later.
