简要总结
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.
详细描述
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.

盲法说明
Only the care provider will know which patients had only twin block treatment and which patients had both twin block and egzersize treatment. Control group will have unrevealant egzercises or no egzercises.

结局指标
主要结局
SNB Angle (sella-nasion-point B Angle at cephalometric analysis)
时间窗: 6 months
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.
SNA Angle (sella-nasion-point A Angle at cephalometric analysis)
时间窗: 12 months
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.
ANB Angle (point A-nasion-point B Angle at cephalometric analysis)
时间窗: 12 months
The difference between SNA and SNB angles
PASmin mm (PAS min = The shortest distance between base of the tongue and the posterior wall of the pharynx at cephalometric analysis)
时间窗: 12 months
The minimal distance between the base of the tongue and the posterior pharyngeal wall, representing the minimal pharyngeal airway space
