Background: In recent years, as the demand for orthodontic treatment has increased, the need to thoroughly investigate the causes of dental and skeletal malocclusions has become more important. In skeletal Class II malocclusion, mandibular deficiency prevalence for 70–80% of cases, maxillary excess for 10–20%, and a combination of both for approximately 15% (Figure 1). In cases associated with mandibular deficiency, clinical features include severe dental crowding, deep overbite, and reduced lower facial height. These conditions negatively affect facial profile, occlusion, masticatory function, and airway. Therefore, accurate diagnosis and appropriate treatment planning are essential. Diagnosis: Skeletal Class II malocclusion, deepbite, and severe crowding. Treatment: in August 2025, using self-ligating brackets with posterior bite up placed on the molars. After 4 months, a temporary anchorage device (TAD) was inserted, and anterior retraction was performed along with vertical elastics. Within 7 months, the overjet was decreased from 7 mm to 3 mm, and the overbite decreased from 7.5 mm to 4.5 mm. Midline deviation and arch form were corrected, and molar and canine relationships improved to Angle Class I. The facial profile also showed noticeable improvement. Conclusion Within a relatively short period after treatment initiation, severe crowding was resolved, and both sagittal and vertical relationships of the anterior teeth improved to normal values. Molar and canine relationships were significantly improved, along with facial esthetics. This case demonstrates that with proper planning, TAD-supported orthodontic treatment can be an effective non-extraction approach for certain cases of skeletal Class II malocclusion with severe crowding.

Background: The physiology and intellectual traits of individuals are interrelated and should be studied comprehensively. In traditional medicine, the teachings of wind (khi), bile (shar), and phlegm (badgan) are considered an integrated system for maintaining health, preventing diseases, diagnosing, and treating illnesses. Aim: Our research is to study students’ physical indicators, body composition, innate characteristics and the relationship between physique and psychological factors. Materials and Methods: The study was conducted on relatively healthy individuals, did clinical observations and used a cross-sectional study design. (defined as those experiencing internal physiological changes that do not impair their work capacity or active lifestyle) Results: Participants were aged 19-25 years, with an average age of 21.5. Heights ranged from 149 cm to 198 cm, with an average of 165.7 cm. Weights ranged from 37 kg to 111 kg, with an average of 61.55 kg. The Body Mass Index (BMI) varied between 15.3 and 36.3, with an average of 22.36. The majority of participants were female (76.4%), while male participants accounted for 23.6%. Regarding individual constitutional types, the most common were: predominantly bile with wind characteristics (21.2%), predominantly bile with phlegm characteristics (30.8%), predominantly wind with bile characteristics (19.6%). Stress survey results ranged from a minimum score of 0 to a maximum of 50, with an average score of 20.6, indicating slightly below-average psychological well-being. The correlation between physiological traits and psychological survey scores was R=0.323** (p=0.001), showing a weak but positive correlation. This suggests that below-average psychological well-being is only minimally influenced by physiological traits. Conclusion The stress survey results indicated an average score of 20.6, slightly below the normal psychological index. The correlation between constitutional traits and psychological well-being was weak but positive (R=0.323**, p=0.001). This implies that individual constitutional characteristics have a minimal effect on psychological well-being. In the study of intrinsic unique characteristics, it has been found that certain physical constitution metrics of the participants demonstrate both positive and negative correlations with the majority of body types, indicating that individuals exhibit varying physical constitution characteristics. Additionally, there exists a positive but weak correlation between intrinsic unique characteristics and stress levels, warranting further investigation.
