Figure 3: Schematic drawing representing the locations of the morphometric measurements performed in this study with the grey rectangle showing the approximate shape and place of the scaffolds/shams. (a) Vertical parameters: buccal bone height (BHH) and lingual bone height (LBH). For scaffold and sham sites, a straight line was drawn along the edges of the scaffold/sham, and bone height was measured where this line intersected the bone crest. In addition, the vertical height difference between buccal and lingual bone crest was measured (lines b and l in (b)). (b) Horizontal parameters: buccal and lingual alveolar wall width (, , ) and buccal and lingual total bone width (, , ) 1, 3, and 5 mm apical of the buccal and lingual bone crest, all measured perpendicular to the long axis of the defect. (c) Vertical bone loss: difference in height () between original bone level and bone level at defect site after six weeks of healing.
