The relationship between static and dynamic occlusion is one of the aspect of study of functional occlusion.Orthodontic treatment has the capacity to change static and functional occlusion. It is assumed that ideal static occlusion is compatible with ideal functional occlusion but it is not necessary.It has traditionally been assumed in orthodontics that correction of the parts of the dentofacial complex to an anatomical norm along with a class I relationship of the buccal segments and alignment of teeth would yield a "good functional occlusion" that is in harmony with temperomandibular...
