Abstract
For the purpose of decreasing the chair time in implant cases,the time needed to loosening and fastening the screw must be shortened.Nowadays,the two typical designs of screw head are slot and hexa form.This study aimed at the shortening of loosening and fastening time by modifying the slot and hexa form.Total of twelve dentists participate in these experiments,four of them were experienced and eight of them were novice dentists.1.There were many differences in the speeds of screw loosening and fastening between personal experiences.Experienced dentists are faster than novice dentists.2.There were many differences in the speeds by angulation of the implant,by the conditions of the muscle tonicity.3.Revised slot and hexa heads show the slightly shortened time for screw looseing and fastening.
