Abstract: A dental stent according to an embodiment includes handles and clamps which are decouplably coupled to main stent bodies depending on a purpose of use, the handles and the clamps enabling dental treatment and surgery to be performed safely and accurately. The dental stent is configured to include main stent bodies that are located in a maxillary or mandibular arch except for a treatment-target and surgical site in the same maxillary and mandibular arch and have respective square connection notches which enable respective handles or clamps to be decouplably coupled to the main stent bodies selectively depending on a purpose; an elastic clip that is coupled to upper ends of the main stent bodies and imparts elasticity to the main stent bodies; and light curing resins that are formed on respective inner walls of the main stent bodies and take a dental impression.

Abstract: The present invention discloses a frictional angled dental implant 100, and the dental implant 100 includes a planted portion 110 being fixedly planted to in an alveolar bone 1, a non-planted portion 130 having the height corresponding to the thickness of gum 2 and provided with an abutment connecting portion 131 on the upper portion thereof, the abutment connecting portion 131 being frictionally connected with an abutment, and a fastening portion 150 for fixedly fastening the non-planted portion 130 to the upper end of the planted portion 110, wherein the central axis I-I of the planted portion 110 and the central axis II-II of the non-planted portion 130 are crossed from each other, and the non-planted portion 130 is formed with a though-hole on the central axis I-I of the planted portion 110, the through-hole being inserted with the fastening portion 150.

Abstract: The present invention discloses a drill bit for removing implant fastening screw which comprises the hole drilling drill bit 110 for axially drilling a hole in the fastening screw which broken or damaged in an implant and the screw lifting drill bit 130 for being firmly fixed the hole of the fastening screw and for lifting the fastening screw, and a guiding socket 120 which comprises the fastening portion 121 for being firmly fastened in the upper end portion of an implant in which a broken or damaged fastening screw is remained and a guiding portion 122 for guiding the hole drilling drill bit 110 to meet the central axis of the fastening screw and the central axis of the hole drilling drill bit 110.

Abstract: A dental implant of the invention allows an immediate masticatory function just after being implanted in a bone structure, does not need a secondary operation, and can be effectively applied even in thin and short alveolar bone. The dental implant comprises a body portion to be inserted in the bone structure and a mounting portion integrally formed on the body portion, the body portion including a thin and short core, screw blades formed along an outer peripheral surface of the core in the shape of a wide and deep screw, and a connecting portion formed in the shape of a plurality of vertical holes and grooves and capable of containing bone growth factors. The mounting portion has a gum adhering portion to protect bone tissues and a post to be mounted with an abutment or a prosthesis thereon.

Abstract: The present invention discloses a drill bit 100 comprising a plurality of cutting blade portions 131 for gradually cutting the surface and the inner wall of bones, a plurality of channels 132 for temporarily storing bone chips produced to be agglomerated by the cut bones and for discharging outside the chips, and a working portion 130 having a blocking portion for blocking further approach of the drill bit 100 after it approaches in the bones as much as the length of the plurality of cutting blade portions 131, wherein the plurality of cutting blade portions 131 and the plurality of channels 132 are alternatively formed to have equal interval in circumferential direction, and at least portion of the bone chips produced to be agglomerated in the plurality of channels 132 is located before the plurality of cutting blades 131.
