Abstract
The development of dentition and occlusion is an integral part of
craniofacial growth as the formation, eruption, exfoliation, and exchange of teeth occur
during this period. It is an assimilation of facts, predictions, and studies in static and
dynamic situations, the factors influencing them, and their clinical implications. The
development of dentition and occlusion is a dynamic concept. The first sign of tooth
development appears late in the third week of intrauterine life. An ideal occlusion is the
perfect interdigitation of the upper and lower teeth, which results from a developmental
process consisting of three main events, jaw growth, tooth formation, and eruption.
Development of occlusion starts before the eruption of first teeth in the oral cavity and
lasts lifelong thereafter.
