CBCT Evaluation of Quality and Quantity of Bones for Immediate Implant Treatment Planning in Central Incisor Area in relation to Arch Form

Table 2

Mean and standard deviation (SD) of facial cortical bone thickness and alveolar ridge width in millimeters (mm) for the upper and lower central incisors according to arch form and gender at three points of measurements ((P1: 3 mm; P2: 6 mm; and P3: 9 mm) from the cementoenamel junction). The data are presented as mean ± SD.
