These appliances, which are used in some of the adolescent patients, require a high level of patient compliance. Because the removal is under the control of the patient, treatment may result in frustration in reluctant patients. The patient needs to know this: Just as a child with a broken arm needs to put his arm in a cast to heal, and this is not a shameful or funny situation, similarly, such an option should be put up with in order to have better teeth in orthodontic treatment.

With the development of surgical options, chin retraction with a surgical treatment after the age of 18 in patients with anterior mandible is a more accepted option today.
