Fig. 2From: The preliminary study for three-dimensional alveolar bone morphologic characteristics for alveolar bone restorationMeasurement of horizontal width of alveolar bone. a Working on a coronal view of the mandibular first molars. b Working on a coronal view of the maxillary first molars. c Measurement of the horizontal width of the interdental alveolar bone crest (m, d) and the teeth (Tw). d Working on volumetric view on mandibular first 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. b, l = buccal and lingual sides; m, d = mesial and distal sides; Tw = width of tooth at the alveolar bone crest levelBack to article page
