Many factors such as direction of mandibular growth, early loss of
deciduous molars, the effect of maxillary and mandibular lengths
and incisor and molar inclination can be associated with crowding.
The aim of study to evaluate the effect of mandibular anterior
crowding on maxillary and mandibular base lengths and ANB
angle in the early mixed dentition .
Lower incisor crowding ( L.I.C ) is identified as the
discrepancy between mesiodistal tooth widths of four permanent
incisors and available space in the alveolar process. However,
incisor crowding is not merely a tooth-arch size discrepancy. Many
factors such as incisor inclination can be affect crowding
development.
the aim of search. Was studying effect of mandibular anterior
crowding on maxillary and mandibular incisor position in the early
mixed dentition.
