The invention relates to a fixation nail for temporarily securing transplantable tissue, bone parts, and bone replacement substances using a cover or for securing natural or artificial bone replacement parts to bones. The fixation nail has a round flat nail head with a diameter of 0.50 to 6.0 mm, and the thickness of the nail head is 0.10 to 2.0 mm. The fixation nail has a nail pin which is formed with a sharp tip, and the pin has a length between 0.5 times to 2 times the diameter of the nail head and a thickness between 0.15 times to 0.5 times the diameter of the nail head. The fixation nail consists of a biocompatible, biocorrodable magnesium alloy which is composed of at least 90 wt. % metal magnesium and contains less than 0.1 wt. % aluminum, less than 0.1 wt. % copper, less than 0.1 wt. % iron, and less than 0.1 wt. % nickel as physiologically undesirable impurities.

An improved fixing pin support for a dental prosthesis in order to be able to connect the dental prosthesis to a jaw by means of fixing pins which can each be moved through a guide bore in the fixing pin support. The improved fixing pin support has a guide sleeve separate from it which can be temporarily fitted over the fixing pin support so that the guide bore can be formed in the fixing pin support through a guide channel in the guide sleeve, by precise guidance of a drill. After this, the guide sleeve can be removed from the fixing pin support.

An intra-bone section of an implant for dental prostheses, to be fixed within the bony part of the gingiva and adapted to receive, upon assembly, a tooth-anchoring superstructure.

It is provided an equipment for treatment of a person, wherein the equipment is configured to achieve a target denture geometry characterized by a target denture plane (3), the target denture plane lying parallel to an internal ear line (11) through a left internal ear point (7) and a right internal ear point (9) of the person. Further, a manufacturing method is provided.

The present invention provides a dental implant that can deal with a subsequent reduction in bone mass while reducing a burden on a patient, and a set thereof. The present invention is directed to a dental implant comprising: a first stage implant 1 that has a bottomed tubular shape, a male thread 3 formed on an outer periphery thereof, and a female thread 4 formed in an inner periphery thereof; and a second stage implant 2 that has a tip part 6 having a male thread 5 threadably engaged with the female thread 4 of the first stage implant 1 and a rear end part 7 to which an upper prosthesis is to be attached via an abutment 8, wherein the female thread 4 of the first stage implant 1 and the male thread 5 of the second stage implant 2 are tapered threads.

The present invention relates to a screw for a dental implant, comprising: a body (122) in which a through hole (124) is formed in the vertical direction; and a cover part (129) formed at an edge on a top end of the body (122), wherein the cover part (129) comprises: a protective body (120) formed by including a horizontal plate (127) formed to have a predetermined area in the horizontal direction and an inclined plate (128) formed downward at an end of the horizontal plate (127); and a connecting bolt (140) that fixes the protective body (120) to a fixture (200) by passing through the through hole (124) to be fastened to the fixture (200) implanted in the alveolar bone, and thus, when the protective body (120) is fixed to the fixture (200) by means of the connecting bolt (140) in the process of implant placement surgery, the cover part (129) covers and protects a bone graft material (320) implanted around the fixture (200), thereby assisting in regeneration of the alveolar bone.

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 retainerless orthodontic dental implant system for positioning the mandible forward relative to the maxilla and for facilitating optimal airflow during sleep and a method of using such a system.

The present invention provides a dental implant that can deal with a subsequent reduction in bone mass while reducing a burden on a patient, and a set thereof. The present invention is directed to a dental implant comprising: a first stage implant 1 that has a bottomed tubular shape, a male thread 3 formed on an outer periphery thereof, and a female thread 4 formed in an inner periphery thereof; and a second stage implant 2 that has a tip part 6 having a male thread 5 threadably engaged with the female thread 4 of the first stage implant 1 and a rear end part 7 to which an upper prosthesis is to be attached via an abutment 8, wherein the female thread 4 of the first stage implant 1 and the male thread 5 of the second stage implant 2 are tapered threads.
