case_images: The patient had a missing upper left second molar and a supernumerary tooth that was present palatal to the upper left first molar and second premolar (Fig 1). Vertical relations were normal (GoGn-SN=31.9 , FMA=26.8 ) and the patient had proclined maxillary and retroclined mandibular incisors (U1 to SN=105.3  and IMPA=83.9 ) (Fig 3A, Fig 10, Table 1). The palatal plan was rotated counterclockwise by 4.8  (Fig 8, Fig 10, Table 1). The palatal plane was rotated clockwise by 1.1 degrees (Fig 9, Fig 10, Table 1).
