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 that is cut out in one direction, and also relates to a dental implant unit including: a crown; an implant structural body which has one side coupled to the crown, and the other side implanted from a gingiva to an alveolar bone, in which the implant structural body has an elastic layer that is cut out to have multiple layers.

The invention relates to an anchoring device (1) for implant-supported removable dental prostheses having a female anchoring part (2); having a male anchoring part (3) connected to the female anchoring part (2); and having a base (4) that comprises a connection geometry arrangement (4A) and an implant thread (4B) for fastening the anchoring device (1) in an implant (6), characterized in that the male anchoring part (3) and the base (4) are interconnected by an elastic connection element (5).

A dental implant includes a fixture implanted into an alveolar bone, an abutment fixed to an upper part of the fixture and having a core hole formed in a center of an upper surface of the abutment, a crown bonded to an upper outer side of the abutment and having a passage vertically formed through a center of the crown, and a cover screw having a screw screw-fastened to the core hole and a head in close contact between an upper surface of the abutment and a lower surface of the crow to cover the core hole, in which, when the screw is released by a tool passing through the passage, the head moves up so that the cover screw provides a separating force to the crown. The dental implant may facilitate a separation of the crown and prevent binding force from weakening, thereby enabling an efficient procedure and management.

A combined assembly for dental prosthesis is provided, wherein the combined assembly includes a first joint member and a second joint member. The first joint member has a first body and a plurality of elastic hooks, and the elastic hooks are annularly arranged to connect one end of the first body, wherein a slot is disposed between the adjacent elastic hooks, and each of the hook has a top portion protruding outward. The second joint member has a second body, and the second body is provided with a joint hole, a side wall surface of which is provided with a ring groove, wherein the elastic hooks extend into the joint holes, and the top portions of the elastic hooks engage into the ring groove.

In a shell for adapting a retention element to an anchoring element, and a method of forming a further retention element on an anchoring element including a shell, the shell has an internal cavity, the dimensions of which are matched to the external dimensions of the retention element and which is connectable to the retention element in an integral or form-fitting manner, and has an outer surface which is formed as a further retention element.

Mechanisms for securing an abutment, removable prosthesis, and/or a fixed prosthesis to an implant without screws or cement are provided. At least a portion of an abutment and/or a fixed prosthesis may be formed from a resilient material to enable the abutment and/or the fixed prosthesis to be secured to secured to the implant without screws or cement. Alternatively, a removable prosthesis may include a spring-loaded snap fastener for securing the removable prosthesis to an implant without screws or cement. The spring-loaded snap fastener may include a metal coil having at least three turns disposed in a same plane. The spring-loaded snap fastener may secure the removable prosthesis to the implant by at least gripping a groove disposed at least a partially around an interface between the removable prosthesis and the implant.

The invention relates to an adapter (1, 1′) for attaching a dental superstructure (50) to a dental implant (30). The adapter (1, 1′) comprises a coronal attachment portion (2, 2′) for attaching the adapter (1, 1′) to the dental superstructure (50), an apical attachment portion (4) for attaching the adapter (1, 1′) to the dental implant (30) and an intermediate portion (6) arranged between the coronal attachment portion (2, 2′) and the apical attachment portion (4). The apical attachment portion (4) is a protrusion defining an apical end portion of the adapter (1, 1′) and configured to be received in a corresponding recess (32) of the dental implant (30). The protrusion is rotationally symmetric, so that the adapter (1, 1′) is rotatable relative to the dental implant (30) in the state of attachment of the adapter (1, 1′) to the dental implant (30). Further, the invention relates to a dental assembly comprising the dental superstructure (50) and at least one such adapter (1, 1′).

An implant abutment according to the present invention is a dental implant abutment with an enhanced shock distribution function, the dental implant abutment comprising: an upper coupling portion that is an upper portion coupled to an artificial tooth; a lower coupling portion that is a lower portion coupled to a fixture, and an exposed portion that is exposed to the outside between the upper coupling portion and the lower coupling portion and has a plurality of flow grooves. By forming a plurality of grooves in the exposed portion of the implant abutment, the exposed portion of the implant abutment performs a shock distribution function as if it shakes elastically and distributes an occlusal force of teeth exerted to the implant, thereby providing a buffering function of relieving an impact on an area where the implant is inserted.

A single tooth implant for a fixed dental prosthesis includes a substantially cylindrical main part which can be inserted into a bore in a jaw bone; an abutment which can be inserted into an annular recess in the main part, the abutment having a bore for receiving a retaining screw and a securing head for the dental prosthesis; and a retaining screw which can be inserted into the blind hole of the main part and traverses the abutment; and at least one annular gap between the abutment and the main part, in which gap a damping element is arranged.

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 alone 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.
