NCT05227469

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • SNB Angle (sella-nasion-point B Angle at cephalometric analysis)

    Cephalometric analysis can be performed to evaluate the cranial base, the relationship of the maxilla to the cranial base, the mandible's size and position relative to the cranial base, the relationship between the maxilla and the mandible, the vertical dimension, maxillary and mandibular dentition, and soft tissue. The angle between the sella/nasion plane and nasion/B plane (normal value at the end of growth 80 ± 2°). This angle assesses the antero-posterior position of the mandible relative to the upper cranial structures. SNB indicates whether or not the mandible is normal, prognathic, or retrognathic.

    6 months

  • SNA Angle (sella-nasion-point A Angle at cephalometric analysis)

    Cephalometric analysis can be performed to evaluate the cranial base, the relationship of the maxilla to the cranial base, the mandible's size and position relative to the cranial base, the relationship between the maxilla and the mandible, the vertical dimension, maxillary and mandibular dentition, and soft tissue. SNA is the the angle between the sella/nasion plane and the nasion/A plane (normal value at the end of growth 82 ± 2°). This angle assesses the antero-posterior position of the maxilla relative to the upper cranial structures. It indicates whether or not the maxilla is normal, prognathic, or retrognathic.

    12 months

  • ANB Angle (point A-nasion-point B Angle at cephalometric analysis)

    The difference between SNA and SNB angles

    12 months

  • PASmin mm (PAS min = The shortest distance between base of the tongue and the posterior wall of the pharynx at cephalometric analysis)

    The minimal distance between the base of the tongue and the posterior pharyngeal wall, representing the minimal pharyngeal airway space

    12 months

Study Arms (2)

Skeletal class II twinblock + myofunctional therapy

EXPERIMENTAL

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.

Behavioral: myofunctional therapy

Control

NO INTERVENTION

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.

Interventions

In order to confirm that the exercises are done for a sufficient time and are done correctly, the researcher will take video recordings from the participants and examine these recordings every other day. Respondents will be contacted when errors are detected.
