Class II cases refusing orthodontic treatment showed increased facial retrognathism despite chin growth. Soft tissue changes highlighted nose and chin prominence, worsening lip posture.

Area of Science:

  • Dentistry
  • Orthodontics
  • Cephalometric Analysis

Background:

  • Class II malocclusion presents specific facial growth patterns.
  • Understanding untreated Class II cases is crucial for orthodontic diagnosis.
  • Pubertal growth significantly influences facial morphology.

Purpose of the Study:

  • To analyze cephalometric changes in untreated Class II individuals during puberty.
  • To describe the soft tissue profile alterations in Class II cases who refused orthodontic treatment.

Main Methods:

  • Longitudinal cephalometric analysis of Class II patients.
  • Examination before, during, and after the pubertal growth spurt.
  • Assessment of skeletal and soft tissue facial profile changes.

Main Results:

  • Increased retrognathism observed despite significant mandibular growth.
  • Facial soft tissues showed enhanced prominence of the nose and chin.
  • Nasal lengthening and thickening occurred, with a decreased nasolabial angle.
  • The relationship between the upper and lower lips deteriorated.

Conclusions:

  • Untreated Class II malocclusion can lead to a more retrognathic profile during puberty.
  • Facial soft tissue growth in these cases accentuates specific features.
  • Orthodontic intervention may be necessary to correct or mitigate these adverse changes.
