This document provides an introduction to orthodontic treatment options in the mixed dentition stage. It discusses treatments for anteroposterior discrepancies like Class 2 malocclusions which can be addressed with functional appliances or fixed functional appliances for the mandible, and headgear for the maxilla. Class 3 malocclusions may involve advancing the mandible or restricting maxillary growth. Transverse discrepancies can be corrected with slow or rapid expansion appliances. Vertical issues can target the anterior or posterior bite. Habit appliances and temporary spacers are also mentioned.
