  1. B1, B2, B3: labial alveolar bone thickness at 3-, 6-, and 9-mm distance from the alveolar crest; θ: measured angle between the line tangent to the margin of the incisor at the alveolar crest level and the line tangent to the outline of the alveolar bone
  2. SD, standard deviation
  3. *P < 0.05, **P < 0.005, ***P < 0.001, statistically significant; paired t test
