Import the image into ImageJ and take measurements. coverage(%): The proportion of component covering bone = ①/(① + ②) X 100. overhang(%): The proportion of component overhanging = ③/(① + ③) × 100. underhang(%): The proportion of bone not covered by the component = ②/(① + ②) × 100. We measured in the anterior (medial anterior area; MA) and posterior (medial posterior area; MP) regions, respectively
