This document discusses different types of vertical malocclusions, including open bite, anterior open bite, posterior open bite, and deep bite. It defines each condition and describes their causes such as thumb sucking habits, tongue thrusting, mouth breathing, and genetic factors. Treatment options are provided for each malocclusion, including removing the underlying cause, orthodontic therapy using appliances like headgear or elastics, functional appliances, surgery, and correcting infraocclusions with crowns. Deep bite is classified as skeletal or dental, and treatment involves intruding or extruding teeth with removable, fixed, or myofunctional appliances.
