Orthodontics · single question

An orthodontic case shows proclined maxillary central incisors, palatally erupted lateral incisors, buccally displaced canines, and lower incisor hypodontia with molars in a Class I (neutral) relationship. What malocclusion classification is present?

  1. Class I malocclusion (with crowding/displacement)
  2. Class II division 1
  3. Class III
  4. Class II division 2
Show answer and explanation

Correct answer: A. Class I malocclusion (with crowding/displacement)

Molars in a neutral (Class I) relationship define a Class I malocclusion; the proclination, displacement, and hypodontia represent crowding/alignment problems within a Class I skeletal/dental base.Other options: Class II and III are defined by anteroposterior molar discrepancies, which are absent when molars are in neutrocclusion.Key exam takeaway: Molar relationship defines Angle class; neutral molars = Class I regardless of crowding.
