by Jamilian Abdolreza

Class III malocclusion is characterized by either maxillary deficiency, mandibular prognathism, or a combination of both. Various devices have been used to correct this malocclusion. If Class III malocclusion is caused by mandibular prognathism, then mandibular setback would be the treatment of choice. The mandibular setback is done in patients 18 years of age or older. This study discusses the treatment plan for class 3 malocclusion in mixed and permanent dentition. Material and methods: In case of maxillary deficiency, many intra and extra-oral appliances are used to treat this malocclusion. Facemask is the most common device that has been used to correct this kind of malocclusion for many years. Face mask, Reverse chin cup can be used as an Extra oral appliance. Nevertheless, many patients do not like to use extra-oral devices due to their bulky size, and many of them lack cooperation. Results and Discussion: This Lecture focuses on other appliances used to correct maxillary deficiency: Reverse chin cup, FR3, Tongue appliance, Tongue plate, Cl III traction combined with miniscrew, and Cl III traction connected with mini plates. The advantages and disadvantages of each device will be discussed. It should be taken into account that the main focus of this Lecture is on the treatment approach and planning.
