The present invention provides a trabecular porous tantalum dental implant and a preparation method thereof. The trabecular porous tantalum dental implant provided by the present invention has a cylindrical structure, and sequentially includes a top functional area, a middle functional area and a bottom functional area from top to bottom. The top functional area has a compact structure. The middle functional area has a porous bionic trabecular structure. The bottom functional area has a compact structure. The trabecular porous tantalum dental implant is integrally prepared through an additive manufacturing technology by using pure tantalum or medical tantalum alloy powder as a raw material. The trabecular porous tantalum dental implant provided by the present invention has a high friction force, strength and modulus close to those of human bones, an excellent bone ingrowth effect, high implantation stability and long service life.

The invention relates to a retention element (1) for attaching a first dental component (20), such as an abutment, to a second dental component (30), such as a dental implant. The retention element (1) comprises a coronal attachment portion (2) for attaching the retention element (1) to the first dental component (20), and an apical attachment portion (4) for attaching the retention element (1) to the second dental component (30). The retention element (1) is elastically deformable at least in all directions perpendicular to the direction from the apical attachment portion (4) towards the coronal attachment portion (2). The apical attachment portion (4) comprises at least one projection (8) extending in one or more directions substantially perpendicular to the direction from the apical attachment portion (4) towards the coronal attachment portion (2). Further, the invention relates to a dental assembly comprising the retention element (1) and to a use of the retention element (1) for attaching a first dental component (20), such as an abutment, to a second dental component (30), such as a dental implant, outside a human or animal body.

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).

A dental reconstruction includes a connection device with a first end bearing on an anchor and a second end supporting a prosthesis. The cross section decreases between the first end and the second end. The connection device defines a through-hole and an abutment. A fastening screw screws into an internally threaded portion of the anchor in order to fasten the connection device. A blocker has a cross section that increases upon insertion of the fastening screw into the through-hole. The blocker fits into a groove of the prosthesis covering the connection device. The screw head has a circular section bearing on the blocker in order to deform the blocker and fit the blocker into the groove of the prosthesis.

The present invention relates to an abutment attachment (100) which can be fastened on a jaw implant (101), comprising an opening (103) for inserting a fixing screw (105); and an adhesive base portion (107) for forming an adhesive base for an adhesive body (109) which is arranged laterally adjacent to the opening (103) and projects beyond the opening (103).

The present invention relates to a connection assembly for attaching a dental component to a dental implant, a dental component for the connection assembly and a method to use the connection assembly. The connection assembly (100; 1100; 2100; 3100) is removably attachable to the dental implant (10; 1010; 2010; 3010), preferably with the dental component (20; 1020; 2020; 3020) attached to the connection assembly, and a dental component is attachable to the connection assembly in a pre-fastened state or a fastened state. The pre-fastened state, when the connection assembly is attached to the dental implant, the connection assembly allows for adjustment of a relative position and/or orientation between the dental component and the dental implant. In the fastened state, the relative position and/or orientation between the dental component and the connection assembly is fixed, while the connection assembly is in particular detachable from the dental implant with the dental component attached to the connection assembly in the fastened state.

An implant includes 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 includes one of at least retention structure and visual alignment indicia is provided to facilitate screwing the implant into a patient's bone.

A dental restoration system is disclosed including an implant for attachment to a jaw bone of a patient. The implant includes a cylindrical body having an interior bore formed between a distal end and a proximal end. An abutment includes an interior bore formed through the stem and the post and an interface section interfacing with the abutment interface of the dental implant. An abutment removal insert has a cylindrical end insertable into a groove formed in the interior bore of the abutment. An abutment removal tool screw is insertable within the abutment removal insert. The abutment removal tool screw includes a grip and an opposite end. The opposite end causes the abutment removal insert to contact the abutment. The grip is rotatable to cause the opposite end to create force against the implant to cause the abutment to be detached from the implant.

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.

An implant abutment capable of stably adjusting vertical dimension of occlusion, the 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; an exposed portion that is a portion exposed to the outside between the upper coupling portion and the lower coupling portion, and an adjustment groove that is formed on an outer circumferential surface of the upper coupling portion and inwardly recessed in the upper coupling portion. According to the implant abutment capable of stably adjusting vertical dimension of occlusion of the present invention, although the abutment has a low upper coupling portion, it can maintain stable coupling with the artificial tooth, thereby ultimately ensuring ease of adjusting a height of the abutment.
