The Vertical Dimension in Complex Orthodontic Case Management

– The vertical control problem in orthodontics
– The 3 domains of vertical control
– Anterior vertical control: incisor intrusion and extrusion mechanics
– Posterior vertical control: molar intrusion and extrusion mechanics
– Mandibular rotation and skeletal vertical control
– Establishing a definitive vertical diagnostic framework
– Systematic diagnostic scheme for the evaluation of a gummy smile
– Assessment of gingival display at rest and during smiling
– Clinical assessment of upper lip length and mobility
– Evaluation of incisor width, height, and periodontal probing depth
– Determining upper incisor position in relation to the upper lip
– Assessment of the Curve of Spee (COS) and root parallelism
– Biomechanical scenarios: mesially tipped posterior segments
– Biomechanical scenarios: mesially tipped posterior segments combined with distally tipped anterior segments
– Fundamental biomechanical principles of vertical movement
– True vertical vs. relative vertical control mechanics
– Detailed clinical case analysis: anterior gummy smile with over-erupted upper incisors
– Detailed clinical case analysis: anterior gummy smile associated with maxillary excess
– Detailed clinical case analysis: anterior gummy smile associated with Vertical Maxillary Excess (VME) and protrusion
– Detailed clinical case analysis: anterior gummy smile with incisor extrusion, an increased Curve of Spee, and a deep bite
– Detailed clinical case analysis: deep bite management via an increased Curve of Spee and lower anterior intrusion
– Detailed clinical case analysis: deep bite management via an increased Curve of Spee and lower posterior intrusion
– Detailed clinical case analysis: open bite with average incisor inclination, decreased incisor exposure, and a tongue-thrust habit
– Detailed clinical case analysis: reduced incisal display – anterior open bite vertical control utilizing TAD mechanics
– Detailed clinical case analysis: increased Lower Anterior Facial Height (LAFH) and anterior open bite corrected via posterior intrusion
– Detailed clinical case analysis: over-erupted molar management using TAD-supported single molar intrusion
– Detailed clinical case analysis: occlusal plane canting correction utilizing TADs
– A simplified, systematic criteria for vertical decision-making.
