Fig. 1. Measurement of marginal bone loss. The ratio of the fixture length measured on the radiographic image to the implant fixture length provided by the manufacturer is used as the amplification ratio. The distance between the alveolar bone crest and the fixture platform top is measured on the mesial side (M) and distal side (D) to obtain an average value. This average value is then multiplied by the amplification ratio to calculate the actual amount of alveolar bone absorption.
