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.
Claims17
A dental implant comprising:
- a body portion to be inserted in a bone structure, the body portion including a core, with a diameter of the core in a range between 1 mm and 7 mm and a length of the core between 3 mm and 10 mm, screw blades formed along an outer peripheral surface of the core in the shape of a screw, with a maximum height of the screw blades from an outer peripheral surface of the core in a range between 0.6 mm and 2.0 mm, and a thickness of a lower end portion of the screw blades between 0.25 mm and 1.5 mm, and a connecting portion in form of grooves or holes for connecting spaces blocked by the screw blades;
- and
- a mounting portion integrally formed on an upper portion of the core and mounted with a prosthesis thereon directly or indirectly,
- wherein a diameter of the screw blades of the body portion has a maximum diameter at an intermediate portion of the body portion, and gradually decreases as it approaches to a proximal end portion of the body portion, and the diameter of the screw blades of the body portion gradually decreases from the intermediate portion of maximum diameter to a distal end portion of the body portion, such that an outer contour of the screw blades in a cross section taken in an axial direction of the body portion has an arc or generally circular shape.
A method of implanting a dental implant for mounting a prosthesis in a bone structure of an alveolar bone, the method comprising the steps of:
- providing the dental implant comprising a body portion including a core, with a diameter of the core in a range between 1 mm and 7 mm and a length of the core between 3 mm and 10 mm, screw blades formed along an outer peripheral surface of the core in the shape of a screw, with a maximum height of the screw blades from an outer peripheral surface of the core in a range between 0.6 mm and 2.0 mm, and a thickness of a lower end portion of the screw blades between 0.25 mm and 1.5 mm, wherein a diameter of the screw blades of the body portion has a maximum diameter at an intermediate portion of the body portion, and gradually decreases as it approaches to a proximal end portion of the body portion, and the diameter of the screw blades of the body portion gradually decreases from the intermediate portion of maximum diameter to a distal end portion of the body portion, such that an outer contour of the screw blades in a cross section taken in an axial direction of the body portion has an arc or generally circular shape, and a connecting portion in form of grooves or holes for connecting spaces blocked by the screw blade, and the body portion to be inserted in the bone structure, and a mounting portion integrally formed on an upper portion of the core and mounted with the prosthesis thereon directly or indirectly;
- forming a drill bit hole in the bone structure of the alveolar bone in correspondence to a diameter of the core;
- forming a screw groove in the bone structure of the alveolar bone in correspondence to the shape of the screw blades;
- and
- implanting the implant in the bone structure through the drill bit hole and the screw groove.
A dental implant comprising:
- a body portion to be inserted in a bone structure, the body portion including a core, with a diameter of the core in a range between 1 mm and 7 mm and a length of the core between 3 mm and 10 mm, screw blades formed along an outer peripheral surface of the core in the shape of a screw, with a maximum height of the screw blades from an outer peripheral surface of the core in a range between 0.6 mm and 2.0 mm, and a thickness of a lower end portion of the screw blades between 0.25 mm and 1.5 mm, and a connecting portion in form of grooves or holes for connecting spaces blocked by the screw blades;
- and
- a mounting portion integrally formed on an upper portion of the core and mounted with a prosthesis thereon directly or indirectly,
- wherein a diameter of the screw blades of the body portion has a maximum diameter at an intermediate portion of the body portion, and gradually decreases as it approaches to a proximal end portion of the body portion, and the diameter of the screw blades of the body portion gradually decreases from the intermediate portion of maximum diameter to a distal end portion of the body portion, such that an outer contour of the screw blades in a cross section taken in an axial direction of the body portion has an arc or generally circular shape,
- wherein the mounting portion has an enlarged outer diameter larger than the diameter of the core, and an inner screw hole for mounting the implant is formed only in the mounting portion without extending into the core.
