To provide a more convenient row of connected artificial teeth which is used for implantation, in this row of connected artificial teeth, a plurality of artificial teeth (11) that are formed of resin are integrally connected, an occlusal face (11a) is formed over one face of each of the artificial teeth, and a hole (12) is provided for at least one of the artificial teeth on an opposite side of the occlusal face, into the hole a coupling member with an artificial tooth root being to be inserted.

A dental implant is provided, wherein the dental implant includes a dental root implant. The dental root implant forms a columnar body, and two ends thereof have a tubular portion and a joint portion, respectively, wherein the tubular portion is provided with a plurality of through holes. A central groove is formed inside the tubular portion and communicates with the through holes, wherein an inner diameter of the central groove tapers from approaching the joint portion to away from the joint portion. The joint portion can be coupled to a dental crown, and the tubular portion can be coupled to a human alveolar bone. The through holes can facilitate an osseointegration of the dental root implant in the alveolar bone.

Apparatus is provided for overdenture with horizontal implant. The apparatus presented comprises an overdenture and a horizontal implant. The horizontal implant is surgically implanted onto the patient's maxilla or mandible, typically on the outside of the bone. The overdenture and the horizontal implant have attachment components which couple together to attach the overdenture to the horizontal implant. The attachment components may comprise ball-and-socket attachments, with the ball components affixed to the overdenture and the socket components affixed to the horizontal implants. The present invention solves problems with currently available dental implants and overdentures.

A dental implant having a central longitudinal axis at a bone-entry portion thereof is provided. The dental implant includes a threaded elongate fixture, at the bone-entry portion of the dental implant, shaped and sized for insertion into a bone of a subject, and a non-threaded emergence collar coronal to the fixture and smoother than the fixture. The emergence collar has a non-circular cross-section at least in a plane that is at least 1 millimeter coronal to the fixture and that is perpendicular to the longitudinal axis, the emergence collar and the fixture being formed of, and adjacently disposed along, a single piece of metal. Other applications are also described.

The present invention relates to a missing tooth supplementing dental prosthesis that may provide the best wearing comfort regardless of the condition of a user's gums as the height of an end of a missing tooth supplementing member is adjusted according to the condition of the user's gums. The present disclosure proposes a missing tooth supplementing dental prosthesis including: a prosthetic body configured to be detachably worn in the oral cavity of a user who has at least one missing tooth, and provided with a fastening portion that is formed in a portion corresponding to a missing tooth; and a missing tooth supplementing member configured to be height-adjustably coupled to the fastening portion of the prosthetic body, to be height-adjusted according to the condition of the user's gums, and to supplement the missing tooth as an embodiment.
