Abstract

This case series study involving 35 patients with impacted anterior palatal supernumerary teeth demonstrated that the majority were localized at the incisive foramen (51.2%), with an inverted orientation being the most prevalent (41.5%). The complication rate associated with these impacted teeth was relatively low at 29.3%. Among these, maxillary incisor displacement was the most frequent complication (50%), occurring primarily in cases of inverted supernumerary teeth situated at the incisive foramen. The rate of favorable surgical outcomes reached 95.2% and was minimally influenced by either anatomical position or eruption direction.
