Malocclusion Conversations: From Aligner Therapy to Occlusal Splints
Occlusion refers to the alignment of teeth and the way that the upper and lower teeth ﬁt together (bite). The upper teeth should ﬁt slightly over the lower teeth. The points of the molars should ﬁt the grooves of the opposite molar. The upper teeth keep you from biting your cheeks and lips, and your lower teeth protect your tongue. Malocclusion is most often hereditary. This means it is passed down through families. It may be caused by a difference between the size of the upper and lower jaws or between the jaw and tooth size. It causes tooth overcrowding or abnormal bite patterns. The shape of the jaws or birth defects such as cleft lip and palate may also be reasons for malocclusion.
