From: Surgically assisted rapid maxillary expansion in lingual orthodontics – optimizing of coupling and timing

Lateral cephalometric parameters Pre-distalisation Post-distalisation Change
SNA angle (°) 80.9 80.4 −0.5
SNB angle (°) 84.6 82.8 −1.8
ANB angle (°) −3.7 −2.3 1.4
Wits (mm) −9.3 −9.8 −0.5
ML-NL (°) 31.9 32.3 0.4

  1. Key: SNA angle between Sella-Nasion-A point; SNB angle between Sella-Nasion-B point;
  2. ANB difference SNA-SNB; Wits: measure of sagittal jaw discrepancy at occlusal leve;
  3. NL palatal plane; ML mandibular plane; UI upper incisor long axis; L1 lower incisor long axis
