A device for the replacement of missing bone and inadequate bone level, the device comprising: one or more implant blocks, shaped to fill in gaps in a jaw bone, the one or more implant blocks comprised of one or more layers characterized by a honeycomb-like structure, and one or more apertures separated by one or more raised crests; one or more screws; one or more tooth implants, the tooth implants shaped to fit in the one or more apertures of the one or more implant blocks, and having one or more internal holes in their base; one or more tooth abutments, the one or more tooth abutments including one or more members on a side complementary to the shape of the one or more internal holes of the one or more tooth implants, and a support structure; and one or more crowns, the one or more crowns shaped to fit over the support structure of the one or more tooth abutments.

A dental implant with a cushion device that can simulate the functions of natural human periodontal ligament (PDL) is provided.

A dental bridge system (10) is provided, comprising a superstructure (14) having a teeth-mimicking portion at a distal end thereof, and at least one receiving cavity formed on a proximal side thereof, at least one support arrangement (12) configured for being fixedly secured, at a proximal side thereof, to an alveolar ridge of an individual, and being formed so as to be received, at a distal side thereof, within one of the receiving cavities to facilitate carrying of the superstructure (14), and a buffering arrangement (16) disposed between the superstructure (14) and the support arrangement (12), the buffer arrangement (16) being configured to damp shock impulses between the support arrangement (12) and the superstructure (14).

A method of damping compressive, tensile, and lateral compressive and tensile forces on one or more prosthetic teeth and an implant recessed into jawbone through use of synthetic periodontal ligament fibers in the form of a damping membrane within a dental bridge assembly. An arcuate damping membrane positions on a full bar and a half-bar positions over the membrane; whereby the damping membrane is sufficiently resilient to enable lateral and axial movements by the prostheses affixed to the half-bar.

A force damping dental bridge assembly which damps compressive, tensile, and lateral forces on a prosthetic tooth and jawbone through use of synthetic periodontal ligament fibers in the form of a damping membrane. Multiple layers of arcuate components and Morse taper interconnections secure the assembly. A threaded implant that penetrates the jawbone defining a tapered, conical inner cavity which receives a shank protruding downwardly from a full bar. An arcuate damping membrane positions on the bar and a half-bar positions over the membrane; whereby the damping membrane is sufficiently resilient to enable lateral and axial movements by the prostheses affixed to the half-bar. A plurality of protuberances extend from an upper surface of the half-bar to enable sculpting and affixation of prostheses thereon; and whereby a plurality of fasteners detachably connect the prostheses to the bar and/or implants in a snap-fit relationship that can be detached with an implement adapted to unsnap the assembly from a patient's mouth.

An dental implant has a substantially cylindrical solid base member; an abutment; an implant-abutment junction (IAJ) portion at one end of the base member to retain the abutment to the base member, so that the abutment is able to move within a predetermined distance in an axial direction of the base member, a first cushion adapted to be mounted between the abutment and the base member, and a second cushion, preferably an elastomer, which is sandwiched between the IAJ portion and the abutment, wherein the first and second cushion are able to provide a resistance force when the abutment is pressed to move relatively toward the base member and providing a bouncing back force when the abutment is released from the pressing.

An dental implant has a substantially cylindrical hollow base member; an abutment; an implant-abutment junction (IAJ) portion at one end of the base member to retain the abutment to the base member, so that the abutment is able to move within a predetermined distance alone an axial direction of the base member, and a first cushion adapted to be mounted between the abutment and the base member for providing a resistance force when the abutment is pressed to move relatively toward the base member and providing a bouncing back force when the abutment is released from the pressing.

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.

The invention relates to an improved damping device for overdentures and prostheses on dental implants, designed to be positioned on dental implants and to bear on same, comprising an elongate body with elastic properties and with a structure in the form of leaf spring, each end of the body being designed to be positioned on dental implants and to bear on same.
