Why Are His Front Teeth Not Straight?

The father of a 7-year-old boy wonders why the upper central incisors, particularly #9, are off (Fig.1 3-D CT tooth coloring).  Fig.2 (bone coloring) does not reveal much. Fig.3 (MIP, more transparent) reveals a supernumerary tooth, called mesiodens (M, an extra central incisor, abnormally shaped (cone), near the midline).  Palatal view shows that the mesiodens points to the midline and distal (arrow).  A palatal gingival sulcus incision will be made to expose the extra tooth (Fig.5).  An elevator will be used as midline and distal as possible to avoid damage to the root of #9 and the tooth bud of #10 (Fig.6 MIP).  Photos will be taken frontally and palatally preop and after incision and exposure of the mesiodens (palatal).
