An effective mesiodens extraction method involving an intraoral approach through the nasal floor bone

Abstract

A mesiodens is a supernumerary tooth located in the maxillary central region, frequently found in an inverted, impacted position, which can cause delayed or ectopic eruption of the permanent incisors. Unerupted supernumerary teeth are typically removed by the traditional palatal or labial approach. However, the traditional approach may induce injury to the adjacent root or damage the surrounding soft tissue because a deeply impacted mesiodens requires excessive bone removal in the anterior maxilla. The aim of the present study was to introduce an effective tooth extraction method involving an intraoral approach through the floor bone of the nasal cavity.
