This study presents two distinct Angle Class II, Division 1 malocclusion cases treated with Tweed-Merrifield directional forces. Both cases achieved similar successful outcomes with an upward and forward resultant force vector.

Area of Science:

  • Orthodontics
  • Dental Malocclusion
  • Biomechanical Force Systems

Background:

  • Angle Class II, Division 1 malocclusion presents complex treatment challenges.
  • The Tweed-Merrifield technique utilizes directional forces for orthodontic correction.

Observation:

  • Two unique cases of Angle Class II, Division 1 malocclusion were analyzed.
  • Each case presented with different diagnostic criteria and treatment approaches.

Findings:

  • Both cases were successfully treated using the Tweed-Merrifield directional forces.
  • The resultant vector of the applied orthodontic forces in both cases was directed upward and forward.

Implications:

  • The Tweed-Merrifield technique demonstrates efficacy in treating diverse Angle Class II, Division 1 malocclusions.
