Most of the reports suggest the supernumerary tooth occurs most commonly in the maxillary arch, in particular the premaxillary
region (95%), followed by mandibular premolar and maxillary molar regions [Zhu et al.

teeth in upper jaw slightly exposed (versus not exposed).
Facial malformations are due to abnormal development of the premaxillary
segments of the face and result in arrhinia and midline facial clefts.
