An osteo-implant is provided, having a fixing segment and an implant end. The fixing segment is provided with a thread and at least one bone healing chamber. The bone healing chamber is located at a thread root of the thread. The bone healing chamber is a chamber inwardly depressed from a surface of the fixing segment. The fixing segment has a central axis. In the same section of the fixing segment, an area of a section, which is parallel to and passes through the central axis, of the at least one bone healing chamber closer to the implant end is smaller.

The present invention relates to a system which comprises a dental implant (10) and a replacement ring (28). The dental implant (10) has an insertion portion for anchoring in a jaw bone. The replacement ring (28) serves for replacing a subtractively removable annular material region in a coronal region of the insertion portion, the shape of the replacement ring (28) being inscribable into the shape of the dental implant (10) in the coronal region at least to some extent such that an inner lateral surface (32) of the replacement ring (28) lies within the shape of the dental implant (10).

The present invention relates to a coupling structure between an abutment and a crown for an implant. To this end, the present invention relates to a coupling structure between an abutment and a crown for an implant, the structure having a lower part of an abutment facing and coupled to, by a bolt, the upper part of a fixture coupled to a tooth-extraction hole of the alveolar bone, and having a lower part of a crown inserted into and coupled to the upper part of the abutment, wherein the abutment has: a support stepped part formed along the edge at the lower part of an abutment body having a stepped hole; a crown supporting guide formed along the edge of the abutment body from the inner upper part of the support stepped part; and an inclined groove part formed at the upper part of the abutment body, and the crown has: an abutment insertion groove, of which the lower side is open, formed at a crown body; a hanging stepped part formed at the edge of an inlet side of the abutment insertion groove; a shock-absorbing layer provided on the inner surface of the abutment insertion groove; and an inclined protrusion part integrally formed at the bottom surface of the inner upper part of the abutment insertion groove. Therefore, the present invention can prevent shock from being transmitted to the abutment through the crown, thereby minimizing a feeling of unfamiliarity, and can reuse the implant since only the resin inserted into a contact part of the crown is separated and new resin is filled therein.

The present invention is to provide implants for an artificial tooth that does not require a period, for integration of implant bodies and a jawbone as in the background art, enables treatment even of a patient whose jawbone is small in bone amount or thickness, can reduce the treatment period and the number of times of treatment for many patients, and can lighten the mental and physical burden of a patient by minimizing the impact to the jawbone, and this invention is characterized by the following means, an artificial tooth, implant device with an arrangement where at least two implant bodies, each having a shaft portion, form a pair, a hook portion, hooked in a hook hole bored in a jawbone, is provided on the shaft portion of each implant body, the hook, portion is bent with respect to the shaft portion, and when the respective implant bodies are hooked onto the jawbone, tip portions of the hook portions are positioned so as to face each other inwardly, the arrangement being provided with a fixing means for fixing the implant bodies to each other.

A bone implant includes: a body including a connection end and a drill end respectively on two ends thereof, with the body including a plurality of engagement sections between the connection end and the drill end, with a disengagement prevention section provided between two adjacent engagement sections, with each engagement section including a drilling thread disposed on an outer periphery of the body, with the drilling threads of the engagement sections having the same thread direction, with the disengagement prevention section including a coupling section on the outer periphery of the body, and with the disengagement prevention section having a maximum outer diameter smaller than a minimum outer diameter of each engagement section between the disengagement prevention section and the connection end; and an abutment seat mounted on the connection end of the body, with the abutment seat including a keying recess.

A dental implant includes an insertion portion which extends along an implant axis, and a coronal projection for receiving an abutment having a dental prosthesis formed thereon, which can be mounted on the dental implant with a screw. The insertion portion includes a coronal region and an apical region. The coronal projection extends from the coronal region of the insertion portion in the coronal direction and along a prosthesis axis. The coronal projection and the insertion portion are integrally connected in one piece. The prosthesis axis and the implant axis are inclined towards each other, and the abutment having the dental prosthesis formed thereon is attachable to the dental implant with only one screwing operation in the direction of the prosthesis axis.

A dental implant assembly comprises a base member and an abutment member. The base member is adapted for placement into an opening in a jawbone and comprises elongated vertically parallel side walls coupled with opposing curved end walls which together define an eccentrically shaped external surface and an eccentrically shaped internal cavity. The base member also includes an eccentrically shaped curved lip which couples top edge perimeters of the external surface and the internal cavity to one another. The abutment member is adapted for placement into the eccentrically shaped internal cavity of the base member. Responsive to placement of the abutment member in the eccentrically shaped internal cavity of the base member, a trans-gingival emergence profile is formed between the eccentrically shaped curved lip and a region of the lower portion between the eccentrically shaped curved lip and the shoulder.

The present invention relates to a dental implant fixture for implanting a correction tooth as a dental implant into alveolar bone. Particularly, the dental implant fixture has self-vertical drilling, self-horizontal drilling, self-cutting, self-condensing, and self-direction changing functions. The dental implant fixture can increase primary stability and penetration performance, has good ability to correct implantation errors, and can minimize the need for drilling that increases the probability of error or failure.

The present invention relates to an endosseous implant assembly adapted for treatment of peri-implantitis. The implant assembly comprises an implant core body configured to receive and couple with implant insert structures that potentially facilitate treatment of peri-implantitis.
