  1. LCA - Labial concavity angle; LCD – Labial concavity depth; MBBH - Mandible basal bone height; TT - tooth torque; MBT0 - mandibular bone thickness at tooth apex; MBT4 - mandibular bone thickness at 4 mm inferior to MBL0
  2. a Spearman correlation
  3. b Pearson correlation
  4. Very strong association: r > 0.850
  5. Strong association: r = 0.650 - 0.850
  6. Moderate association: r = 0.350 - 0.649
  7. Weak association: r = 0.200 - 0.349
  8. Very weak association: r < 0.200
