A convertible dental assembly is disclosed herein. The convertible dental assembly includes abutments adapted for fixing with implants; fixed-hybrid housings adapted for fixing with the abutments through a fixing screw; and removable-hybrid housings, adapted for engagement with abutments through snap fit parts. The fixing screw and the snap fit part are fixed to the abutments through same female threads on the abutments. The fixed-hybrid housings are used for a fixed-hybrid dental assembly during period of healing of the implants, and replaced by the plurality of removable-hybrid housings along with the snap fit parts for a removable-hybrid dental assembly after the period of healing of the implants. The fixed-hybrid housings and the removable-hybrid housings can be captured in the dental assembly via chair-side pickup at respective instances. The removable-hybrid housings can be placed indirectly by a dental laboratory if a new denture is being fabricated. The abutment includes an outer frustoconical profile that engages with matching frustoconical cavities in the fixed-hybrid housings and removable-hybrid housings.

The present invention relates to endosseous implants and in particular, to screw form dental implants for implanting within bone. The bone implant is configured to be a self-drilling bone implant that is adept at condensing, collecting and distributing bone along all of the implant's surface and within the implantation site, to significantly increase the bone implant contact surface. The implant is configured to have a coronal portion and a body portion that are continuous with one another. The coronal portion is configured to have a smaller overall diameter than the overall diameter of said body portion. The body portion is fit with threading that facilitates the self-drilling and bone collection properties when the implant is rotates in both the clockwise and counterclockwise directions.

The present invention provides a dental implant comprising: a first coupling part 150 is provided on an inner surface of the axial hole of the fixture, the first coupling part comprising a coupling recess depressed outward, in a predetermined location on the inner surface of the axial hole, and a first corresponding coupling part provided on an outer circumferential surface of the coupling leg 122 to be complementarily coupled to the first coupling part 150, the first corresponding coupling part comprising a coupling protrusion, wherein, in a state in which the abutment is fitted into the fixture by complementary coupling between the first coupling part and the first corresponding coupling part; when a rotation force applied to the abutment has less than a predetermined level, the abutment is prevented from rotating relative to the fixture in a circumferential direction, and when the rotation force applied to the abutment is equal to or greater than the predetermined level, the coupling leg of the abutment is elastically bendable radially inwardly toward a central axis and the abutment is rotated in the circumferential direction, allowing the coupling protrusion of the first corresponding coupling part to be released from the coupling recess of the first coupling part, so that the fixture and the abutment are decoupled from each other.

Improved devices, systems, and methods for securing a dental prosthesis within an oral cavity of a subject are disclosed. In one embodiment, an implant system comprises an implantable abutment comprising a threaded fixation portion and an abutment portion. At least part of the threaded fixation portion can be configured to be implanted within the alveolar bone or alveolar process of the subject and at least part of the abutment portion can be configured to protrude beyond the gingiva of the subject. The system can also comprise a sleeve comprising a sleeve frame and a plurality of locking tabs configured to lock the sleeve to the abutment portion and lock a dental coping to the abutment portion. The threaded fixation portion can be defined by an exterior tubular profile and wherein the abutment portion can be set within the exterior tubular profile.

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.

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.

A set of instruments with portions shaped and sized to engage specific portions of a dental implant is provided. Each of the instruments includes a tip on an end of a shank, the tip including an arcuate portion transverse to a longitudinal axis of the end of the shank. The arcuate tip portion may be crescent or hook shaped.

The coronal portion is configured to have a smaller overall diameter than the overall diameter of said body portion. The body portion is fit with threading that facilitates the self-drilling and bone collection properties when the implant is rotates in both the clockwise and counterclockwise directions.

An abutment for holding a dental prosthesis to a jaw implant, having: an apical section detachably fastening the abutment to the jaw implant, the apical section being structured along a first central axis; a coronal section detachably fastening the dental prosthesis to the abutment, the coronal section being structured along a second central axis, wherein the second central axis extends at an angle to the first central axis; and an indexing element in a shell surface of the coronal section specifying an orientation of a display element that is coupleable to the coronal section for a digital scanning operation, based on an orientation of the first central axis. A display element coupling to an abutment coronal section, and displaying a position and orientation of the abutment for a digital scanning operation, a tooth model system having an abutment and a display element, and a method producing a dental prosthesis.

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.
