“…Stratification analysis was conducted on cephalometric parameters in accordance with previous studies [ 20 – 22 ]. Patients were divided into skeletal class I (0° ≤ ANB ≤ 4°), class II (ANB > 4°), and class III (ANB < 0°) according to ANB.…”

Purpose. To explore the relationship between craniomaxillofacial features and psychological distress among adult pretreatment orthodontic patients. Methods. A group of 190 patients (95 males and 95 females) was included. Questionnaires including the Kessler psychological distress scale (K10) were sent to patients, and cephalograms were collected. Patients were divided into two groups according to K10 score: psychological distress group ( score ≥ 20 ) and no psychological distress group ( score < 20 ). Nineteen hard tissue and thirteen soft tissue parameters were traced on cephalograms to characterize the craniomaxillofacial features. Results. There was no significant difference in gender or age distribution between the two groups. Male patients with psychological distress showed statistically significantly larger anterior facial height (AFH) (126.62 mm vs. 120.97 mm), upper lip length (25.11 mm vs. 23.26 mm), and smaller overbite (1.21 mm vs. 2.75 mm) than patients without psychological distress. Male patients with hyperdivergent pattern and open bite were more likely to have psychological distress. None of the parameters showed statistical differences across groups in females. Frankfort-mandibular plane angle ( r = 0.235 ), Bjork’s sum ( r = 0.311 ), AFH ( r = 0.322 ), overbite ( r = − 0.238 ), AFH/posterior facial height ( r = 0.251 ), and upper anterior facial height (UAFH)/lower anterior facial height (LAFH) ( r = − 0.230 ) were correlated with K10 score in males. After adjusting gender and age, the AFH ( B = 0.147 ) and UAFH/LAFH ( B = − 14.923 ) were significantly related with the K10 score. Conclusion. Psychological distress was mainly correlated with hyperdivergent pattern, open bite, and larger lower anterior facial height proportion in pretreatment orthodontic patients. Orthodontists should be aware of the possible underlying psychological distress in patients with specific craniomaxillofacial features. Clinical assessment of psychological distress may need to take into account gender differences in patients.

“…The effect of orthodontic treatment in adolescent patients with skeletal Class II malocclusion is better. The mandibular growth trend (direction) in patients with skeletal Class II versus skeletal Class I does not differ throughout puberty, but the growth is not static [47]. Bishara et al [48] found that the growth trend of skeletal Class II mandibles was not significantly different from that of normal mandibles in each dentition period.…”

Timing of early correction of mandibular hypoplasia in skeletal class II malocclusion: a review

Skeletal Class II malocclusion is a common malocclusion seen in clinics. It is characterized by maxillary protrusion and mandibular retrognathia and has a high incidence in adolescent mixed dentition and early permanent dentition. The early functional correction has achieved some clinical results in treating skeletal Class II malocclusion with mandibular hypoplasia. During treatment, the timing of correction is the key factor in determining the therapeutic effect, although it is difficult to understand. This review focuses on the timing of early correction of mandibular hypoplasia in combination with relevant assessment indicators and historical literature from four perspectives—the law of mandibular growth and development, the necessity of early treatment, the timing of early treatment, and the determination of the peak period of mandibular growth and development—to provide a theoretical reference for the timing of the treatment of clinical skeletal Class II malocclusion. This review shows that skeletal Class II mandibular growth has different characteristics in males and females. Bone growth assessment before treatment helps diagnose mandibular developmental morphology and the timing of early correction in adolescents with skeletal Class II malocclusion and hypoplasia of the mandible.
