Presentation Transcript

  1. Vertical skeletal pattern • Different way to assess vertical skeletal pattern • lower anterior face height • Frankfort mandibular plane angle

  2. Skeletal pattern (Vertical : LAFH)

  3. Lower Anterior Facial Height (LAFH) • Is used to assess vertical dimension • Ratio of the LAFH to the total face height gives an indication if the LAFH is within normal limits • Facial proportion (LAFH %) = MxPl to Me x 100 MxPl to Me + MxPl to N = 55% ± 2%

  4. Frankfort mandibular plane angle (FMPA) • It measures the relationship between LAFH and posterior face height • Normal: mandibular and frankfort lines intersect in occipital region • Increased:anterior to occipital region • Reduced:posterior to occipital region
