Figures & Tables

Figure 1.

Transverse discrepancy observed in a patient who was diagnosed of maxillary deficiency and required maxillary skeletal expansion. Maxillary basal arch width was significantly smaller than the lower basal arch width. Dental compensation was often observed in the lower molars.

A clinical assessment of posterior tongue tie. The patients with posterior tongue tie showed cupping of the tongue during attempted elevation when the bottom of the tongue was being held down by the examiner.
