There have been many reports showing the usefulness of CT examinations for preoperative dental implant treatment, and some reports on clinical statistics using CT examinations. However, there have been few reports on alveolar bone height and width of over 1,000 Japanese cases.<br/>The purpose of this study was to evaluate alveolar bone height and width of 4,123 sites in 1,056 Japanese cases using preoperative CT examinations.<br/>The subjects consisted of 4,123 regions in 1,056 cases (370 males and 686 females, mean age 56.1 years old, range 15-87) of preoperative CT examinations conducted from January 2008 to March 2009. The CT examinations were performed using the AquilionTM64 (Toshiba Medical Systems Corporation) as the MDCT unit, and ZIOSTATION (ZIOSOFT) as the workstation. The CT images were displayed on the workstation, and the alveolar bone height and width were measured to one decimal place (rounded off to two decimal places).<br/>The average alveolar bone height was 14.8 mm (SD 3.8) in the upper anterior area, 11.2 mm (SD 5.5) in the upper premolar area, 6.8 mm (SD 5.4) in the upper molar area, 19.5 mm (SD 5.4) in the lower anterior area, 14.2 mm (SD 3.9) in the lower premolar area, and 13.4 mm (SD 3.4) in the lower molar area.<br/>The average alveolar bone width was 4.3 mm (SD 1.9) in the anterior area, 5.7 mm (SD 2.3) in the upper premolar area, 7.9 mm (SD 3.1) in the upper molar area, 4.8 mm (SD 2.1) in the lower anterior area, 5.9 mm (SD 2.2) in the lower premolar area, and 6.9 mm (SD 2.5) in the lower molar area.<br/>Our results using preoperative CT examinations indicated that many of the Japanese cases had insufficient alveolar bone height and width for dental implants.
