Orthodontics · single question

Same case. All of these characteristics may be present EXCEPT:

  1. Anterior open bite
  2. Anterior crossbite (not typical of this Class II Division 1 presentation)
  3. Missing teeth
Show answer and explanation

Correct answer: B. Anterior crossbite (not typical of this Class II Division 1 presentation)

  • A. Anterior open bite can be a feature seen in some Class II Division 1 cases (e.g., associated with certain habits/skeletal patterns), making it a plausible finding.
  • B. Correct (the exception). Anterior crossbite is not typical of Class II Division 1 malocclusion, which features protrusive (not retroclined/crossbite-tendency) maxillary incisors — crossbite is more associated with Class III or specific transverse discrepancies.
  • C. Missing teeth (mandibular hypodontia) is explicitly described as present in this case.
