Abstract:
The present invention relates to an implant-abutment comprising: a fixture, which is coupled to an alveolar bone and comprises on the inside thereof a female tapered part having a tapered shape; an abutment, which has one side comprising a male tapered part, which has a shape corresponding to the female tapered part so as to be coupled to the female tapered part in an engaging manner, and the other side having a prosthesis coupled thereto; and an elastic part provided between the female tapered part, and the male tapered part so as for the abutment to move between a locking position, in which the abutment stays coupled to the fixture and is inhibited from moving away from the alveolar bone, and a sinking position, in which the abutment moves and sinks toward the alveolar bone by the occlusal force of occluding teeth. Configured as such, the present invention allows slight movement under a predetermined external, force by the occlusal force of teeth while stably maintaining the state of being coupled to the fixture and allows the abutment to be separated and easily retrieved from the fixture, if necessary, by the application of an external force equal to or greater than a target coupling force whereby the fixture and abutment stay coupled.

Claim (Index 15):
An implant-abutment device, comprising:\n an elastic member having a ring shape; an abutment that is formed with both a male tapered part tapered on one side and an elastic member coupling groove or an clastic member groove provided in a circumference direction of the male tapered part so as to accommodate one side of the elastic member; and a fixture that is formed with both a female tapered part, into which the male tapered part is inserted, tapered on one side and the elastic member coupling groove or the elastic member groove provided in a circumference direction, of the female tapered part so as to accommodate the other side of the elastic member when the male tapered part is inserted and contacted into the female tapered part, wherein, when the elastic member coupling groove is formed in the abutment, the elastic member groove is formed in the fixture, and when the elastic member groove is formed in the abutment, the elastic member coupling groove is formed in the fixture, wherein, when the male tapered part is inserted and contacted into the female tapered part, the elastic member coupling groove and the elastic member groove are formed to support the elastic member, such that the abutment and the fixture are coupled to each other. wherein, when a force that is greater than a predetermined force is exerted, the elastic member coupling groove is formed to secure a space in a radius direction so as to accommodate the elastic member separated from the clastic member groove, such that the abutment is separated from the fixture, and wherein, the elastic member groove is lengthily formed in an axis direction, such that a pressurizing force is not exerted on the elastic member when the abutment exerts the pressurizing force on the fixture.
