Fig. 3From: The preliminary study for three-dimensional alveolar bone morphologic characteristics for alveolar bone restorationComparison of horizontal alveolar widths between a maxillary and b mandibular alveolar bone. CI, central incisors; C, canines; PM, premolars; M, molars; d1 = bone width at the crestal level; d2 = bone width at the mid-root level; d3 = bone width at root the apex level; d4 = bone width at the mandibular border level (*P < 0.05)Back to article page
