Abstract: A dental implant has at least one and preferably a plurality of wedges extending from the end of the implant body opposite that provided with the superstructure for receiving the dental prosthesis. The wedge-shaped bodies penetrate into the spongiosa and allow the bore cavity for receiving the implant to be shorter and the drilling process less traumatic.

Abstract: A drill bit for producing bone cavities for dental implants having a shaft which is indexable in a dental drill handpiece and a cutting head for removal of the bone tissue. Between the shaft and the cutting head, a bit body is provided whose cross section has reduced dimensions by comparison with the bone cavity formed by the cutting head.

Abstract: A device for retaining a tooth set such as a bridge in the mouth of a patient has an implant with an anchor end received in a drilled cavity in the jaw and provided with longitudinal flutes. On the crown anchor at the opposite end of this implant, a two-part crown can be provided. The primary crown part is connected to the crown carrier by a screw and has an external taper onto which the secondary crown part can be applied with adhesive friction. The secondary crown part is anchored in the artificial tooth set.

Abstract: Implant cavities are drilled in the jaw of a patient by first forming a template from a plastic cast of an impression of the jaw regions after it has been prepared as for parallel-crown preparation and the template is provided with parallel bores in which slide sleeves guiding the drill bit of the drill can be received.
