Fig. 1

On periapical radiographic image, fixture length (h) and marginal bone levels at direct bone–implant contact points (a) and distant crestal points (b) were measured using image processing program (Image J, National Institute of Health). Using measured lengths, actual marginal bone level was calculated by proportional formula [H:X = h:a(or b)] (H = known actual length of implant fixture, X = actual marginal bone level)
