Thumb sucking, if continued beyond the age of two, is commonly acknowledged to compromise correct craniofacial development, with consequent dental malposition. The observation of a deciduous central incisor morphology, lost traumatically by a thumb-sucking three years old boy with an apparent open-bite, makes us think this bad habit can influence teeth morphogenesis too.
人们普遍认为，吮拇指行为如果持续到两岁以后，通常会影响正确的颅面发育，进而导致牙齿错位。一名三岁男孩因吮拇指导致乳牙中央门牙外伤性脱落，且明显存在开颌现象，对其乳牙中央门牙形态的观察使我们认为，这种不良习惯也会影响牙齿的形态发生。
