Fig. 1. The mean alveolar bone resorption was measured radiographically using the PACS program. The mesial and distal measurements of the linear distance between the implant shoulder and the bone–implant contact were taken and averaged to determine the mean bone resorption. a: assumed mesial bone resorption. b: assumed distal bone resorption. Mean bone resorption=(a+b)/2.
