Abstract:
1. A mount device for a dental implant to place a fixture in an alveolar bone, the fixture having an inner hole formed inside to have a predetermined depth along a lengthwise direction from an upper end of the fixture to a lower end thereof, the mount device comprising: a mount screw including a body portion having a first screw portion provided at the lower end of the body portion to be capable of screw coupling to a first inner screw portion of the fixture and a second screw portion having a screw formed in a direction opposite to a direction of a screw of the first screw portion and provided at a position separated a predetermined distance upward from the first screw portion, and a head portion having a sectional area larger than that of the body portion, coupled to an upper end portion of the body portion, and detachably coupled to a handpiece for a dental use through a handpiece connector; and a mount having an inclined surface formed on at least one of an inner wall and an outer wall of the lower end portion for a conical connection to the upper end portion of the fixture, an insertion hole formed inside the mount along a lengthwise direction from the upper end to a lower end thereof by penetrating the mount, and a second inner screw portion formed on an inner wall of the insertion hole and capable of screw coupling to the second screw portion, wherein, to remove a screw coupling between the second inner screw portion of the mount and the second screw portion of the mount screw when an upper end surface of the mount contacts a lower end surface of the head portion of the mount screw, a distance from a lower distal end of the second inner screw portion of the mount to the upper proximal end of the mount is less than a distance from an upper proximal end of the second screw portion of the mount screw to a lower distal end of the head portion.
