A dental prosthetic arrangement and a dental prosthetic system include a combination of a lower part assigned to a jaw implant and an upper part assigned to a prosthesis body in a connection section, wherein in particular two bearing faces are produced in the connection section when in the connected state, the bearing faces being cylindrical, preferably circular-cylindrical in relation to a center axis and being spaced apart from each other in the axial direction. The axial extent of the cylindrical bearing faces is advantageously small compared to the axial extent of the connection section. The two cylindrical bearing faces are preferably situated in axially opposite end regions of the connection section and are connected to each other by approximately conical wall faces of a cut-out in the upper part and a projection of the lower part that projects into the latter.

An implant for dental prostheses includes an endosseous portion and a stump. The endosseous portion includes a crown margin configured to be opposed to a corresponding crown margin of the stump. At least one of the crown margins is conical or however has a different taper with respect to the opposed crown margin so that, once the stump has been coupled to the endosseous portion, the contact and interference surface between the crown margins is a reduced annular surface.

An implant comprising two internal anti-rotational features. One anti-rotational feature is adapted to engage a driving tool, while the other anti-rotational feature is adapted to engage an abutment. An implant abutment system is provided with an angled abutment adapted to mate with one of the anti-rotational features. A second, straight abutment is adapted to engage with the other anti-rotational feature. An abutment is provided with resilient fingers to interface with the implant and provide tactile and audible feedback indicating when the abutment is properly seated. An abutment screw extends through the abutment and engages the implant bore distal of the stem of the abutment. The abutment screw limits axial movement of the abutment relative to the implant. A driving tool comprising one of at least retention structure and visual alignment indicia is provided to facilitate screwing the implant into a patient's bone.

The present invention relates to an implant unit, particularly, a dental implant unit for mitigating impact which may be substituted for a natural tooth, the dental implant unit including: a crown; an abutment which has one side coupled to the crown; and a fixture which is coupled to the other side of the abutment, in which at least one of the abutment and the fixture has an elastic layer, and also relates to a dental implant unit including: a crown; an abutment which has one side coupled to the crown; and a fixture which is coupled to the other side of the abutment, in which at least one of the abutment and the fixture has an elastic layer that is formed at a portion which is in contact with a gingiva when an implant operation is performed using the dental implant unit.

Provisional prosthetic systems and methods of coupling such provisional prosthetic systems to a dental implant are disclosed. The provisional prosthetic system can include at least one dental component having a provisional connection feature and a prosthesis. A clinician can couple the prosthesis to the dental component using a bonding agent. The clinician can then drill a hole through the prosthesis. The hole can be configured to receive a fastener to securely fasten the prosthesis and dental component to the implant.

A dental implant assembly includes an implant, an abutment, and a fixing element. The implant is placed in the alveolar bone. The abutment is assembled to the implant and includes a tapered position-restricting part and an elastic pressing part. The tapered position-restricting part has an abutment fixing channel substantially matching the tapered position-restricting outer wall of the tapered position-restricting trench. The elastic pressing part includes the elastic pressing structures extended from the tapered position-restricting part. The fixing element includes the fixing head and the fixing rod extended from the fixing head. A tolerance allowable gap is formed between the abutment fixing channel and the fixing rod. As the abutment is assembled to the implant, the elastic pressing structures press against the position-restricting wall first to hinder the relative rotation therebetween; when an offset error exists, the tolerance allowable gap allows the fixing rod to penetrate the abutment fixing channel.

A system for attaching a natural tooth to a dental implant includes a dental prosthesis and an elastomeric cushion. The elastomeric cushion is positioned in contact, either directly or indirectly, with at least a portion of the dental implant and at least a portion of the dental prosthesis such that the elastomeric cushion permits movement of the dental prosthesis relative to the dental implant in response to movement of the natural tooth transferred through the dental prosthesis.

The present invention relates to a dental implant structure including an abutment and a crown (artificial tooth), and more particularly, according to the present invention, a crown is not fixed to an abutment through an adhesive, but is coupled and fixed to the abutment with a locking part having various structures, so it is possible to easily detaching the crown, and an elastomer is formed on an outer surface of a post of the abutment or an inner surface of the crown to block a direct contact of the crown with the abutment, so it is possible to buffer and relieve occlusal force repeatedly applied to the crown using elastic force to prevent the crown, the abutment, and/or the fixture, or the like from being fractured due to the repetitive occlusal force, and prevent foreign substances from entering between the crown and the abutment.

The present invention relates to an abutment screw-separable dental implant structure in which an abutment is fastened and fixed to a fixture implanted in an alveolar bone through an abutment screw, and more particularly, to a dental implant structure in which, as a head part of an abutment screw protrudes upward from a post of an abutment without being accommodated in the abutment, a diameter (inner diameter) of an inner space of the abutment may be reduced to freely form a diameter and thickness of the post of the abutment to a desired size.

An implant comprising two internal anti-rotational features. One anti-rotational feature is adapted to engage a driving tool, while the other anti-rotational feature is adapted to engage an abutment. An implant abutment system is provided with an angled abutment adapted to mate with one of the anti-rotational features. A second, straight abutment is adapted to engage with the other anti-rotational feature. An abutment is provided with resilient fingers to interface with the implant and provide tactile and audible feedback indicating when the abutment is properly seated. An abutment screw extends through the abutment and engages the implant bore distal of the stem of the abutment. The abutment screw limits axial movement of the abutment relative to the implant. A driving tool comprising one of at least retention structure and visual alignment indicia is provided to facilitate screwing the implant into a patient's bone.
