Fig. 2From: A comparative study of the effect of drilling depth on generation of compressive force by headless compression screws using conical and cylindrical type of drill bitA load cell was placed between 12-mm- and 20-mm-thick Sawbone blocks (grade 15 pcf, [0.24 g/cm3]), which maintained a 1-mm space between the blocks. After placing the guide pin into the center of the block, drilling was performed to a predetermined depth, and the screws were insertedBack to article page
