Anatomical and biological studies indicate that the phylogenetic development and on-togeny of the human comprise a number of important environmental factors that are implicated in evolutionary and devolutionary transitions of the stomatognathic system. Normal occlusion is one of the basic concepts of normal stomatognathic function. There are several essential static and dynamic aspects in the anatomy of ideal occlusion, as well as morphological and physi-ological features.
