A dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.

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.

A dental device comprises: a dental implant comprising a core enveloped by an expandable anchor comprising a plurality of joined segments. Prior to insertion of the core into the expandable anchor a carrier apically displaces within the expandable anchor, generating an expansion force causing the plurality of joined segments to be displaced linearly away from the central axis of the implant where the coronal and apical ends of each joined segment are displaced in parallel paths normal to the central axis of the implant. The core inserts into the expandable anchor to lock the plurality of joined segments in their expanded configuration. At least a first rail on the core is received by a corresponding expandable anchor slot to align the core and expandable anchor and at least a first core and expandable locking lodge engage to lock the core into the expandable anchor.

Provided is an implant unit, and more particularly, a dental implant unit. The implant unit includes a fixture assembled to an alveolar bone; and an abutment assembled to the upper portion of the fixture, wherein the fixture includes a space defined by a groove-like structure formed in depth direction from the lower portion of the fixture facing the alveolar bone.

An intra-procedure dental implant stabilization and healing system that includes a soft tissue forming scanning abutment and associated, temporary crown. After initial implant placement, a scanning abutment of the present system is attached to the implant and serves, both as a scanning body and, in combination with a temporary crown attached thereto, as a healing cap. Use of the system obviates an additional surgical incision to reach recipient osseointegrated implant, as is required in conventional implant procedures, as well as the need for a conventional impression coping, separate healing cap, temporary abutment and temporary crown.

A dental anchoring system includes an angled abutment, having a main body extending from a top to a channel body, the channel body extending away from the main body at a predetermined angle less than 180 degrees; a lip extending around the top; and an opening extending from the top and through the channel body, the opening to receive an attachment device; the angled abutment is to provide an angled attachment for a dental prosthetic.

The present invention provides a dental implant including: a fixture and an abutment including a coupling leg, and the fixture and the abutment are elastically coupled with each other, the dental implant including: a fixture axial hole inner inclined surface in which an inner diameter of an axial hole is gradually and downwardly reduced from a predetermined position of an inner inclined surface of the fixture; a first coupling part formed with a coupling hole at a predetermined position of the fixture; and a first associated coupling part formed with a coupling protrusion complementarily coupled with the first coupling part, wherein when the first associated coupling part is separated from the first coupling part by rotating the abutment, the coupling protrusion upwardly pushes the abutment from the fixture by elastic repulsion with the axial hole inner inclined surface of the fixture, thus the abutment becomes separated from the fixture.

A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.

Provided is a dental implant unit capable of reducing stress. The implant unit includes an fixture, which is assembled to an alveolar bone and includes a long hole therein; an intermediate structure inserted to the long hole of the fixture; and an abutment assembled to the intermediate structure, wherein the lower portion of the long hole of the fixture has a sloped surface, the lower portion of the intermediate structure also has a sloped surface, and at least a portion of the sloped surface of the long hole and at least a portion of the sloped surface of the intermediate structure contact each other.
