Thumb sucking is one of the most common bad habits in childhood. Its prevalence varies between 10 and 34 % in developed countries. In case of long persistence, mainly during the mixed dentition period and high intensity, structures of developing splanchnocranium may be influenced. Thumb sucking is associated with higher prevalence of upper incisor protrusion, open bite and upper dental arch compression. If the intensity of thumb sucking is extreme high, symptomatology of sagittal skeletal maxillary growth stimulation can be observed in rare cases.

Authors of this paper are presenting three cases reports with typical clinical symptomatology of splachnocraniums growth changes associated with thumb sucking.
