About

There are situations where orthodontic treatment cannot provide long-term benefits. The proposed orthotropic theory proposes that environmental factors cause malocclusion and genes decide its pattern. The primary aim of this project is to increase the success, aesthetics and permanence of the treatment result by providing the best facial change of the pediatric patients in the MP3cap period, and that myofunctional exercises can be used in addition to orthodontic treatments during the treatment process of the patients.

Full description

Many studies in recent years have emphasized the importance of the environmental factor as well as the hereditary causes of malocclusion. In particular, the activity and posture of the oral soft tissues have begun to be mentioned more. In the presence of bad habits, there are cases where orthodontic treatment alone is not sufficient and must be combined with myofunctional treatments. There are also many physicians who emphasize the importance of positioning the tongue in contact with the palate during swallowing and resting.

It is known that habits during growth and development cause malocclusions that may occur in the future. It may be possible to acquire some myofunctional exercises as a habit during the growth and development period as a prophylactic solution against malocclusions. In addition to twin block treatment, myofunctional exercises will be given to class II pediatric patients in the MP3cap period, and the effect of exercises on oral soft and hard tissues will be compared at the end of the treatment. The effects of tongue and lip movements on facial development as well as on the treatment process will be examined. Perhaps in the future, everyone can recommend doing myofunctional exercises in addition to tooth brushing.

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

36 participants in 2 patient groups

Skeletal class II twinblock + myofunctional therapy

Experimental group

Description:

Myofunctional exercises will be prescribed in addition to the standart twin block therapy. Movements will be taught to this group, for which we have prescribed the exercises. It will be ensured that the exercises are done more properly and regularly by taking video recordings every other day from the group that does the exercises twice a day. Incorrect exercises will be corrected by providing feedback.

Treatment:

Behavioral: myofunctional therapy

Control

No Intervention group

Description:

Standard twin block therapy will be used for Class II patients. Patients will be informed that they are involved in a study that follows growth and development, and they will receive feedback on whether they use their devices properly, but no myofunctional exercise.
