Problems solved by technology

Surprisingly, however, this solution comes at the cost of a durability defect, which results in the dental technician or dentist having to replace the dental restoration within a short period of time or even being liable for damages

Embodiment Construction

[0061] figure 1 The abutment 10 shown in has an implant connection region 12 which extends in the direction of the neck and terminates at a flange 14 . The flange merges via an inside fillet into a pipe section 16 which is provided for receiving and supporting the superstructure.

[0062] The tube section 16 has a groove 18 as a radially inwardly extending anti-rotation structure. The groove 18 prevents inadvertent rotation during installation of an abutment for an individual restoration, such as a dental crown, and thus serves as an anti-rotation protection. Correspondingly, corresponding strips are then formed in the superstructure, which fit into the grooves 18 .

[0063] When the abutment is used for an abutment tooth of a dental bridge, the groove 18 retains the shape shown here. Internally, however, there are no slats engaging the slots 18 on the superstructure. As a result, the anti-rotational fixation of the dental bridge can be ensured by proper alignment relative...

Abstract

Device for producing tooth replacements, which device has a milling cutter (36) for shaping the front face of the tube portion (16), which milling cutter (36) has at least one abutment face which is intended to bear at least indirectly on a surface of the abutment (10), in particular on the collar (14) of the abutment, and via which milling cutter (36) the length or height of the tube portion (16) of the abutment (10) can be fixed, in particular the tube portion can be shaped. Tool set consisting of a milling cutter (36) and of a sleeve (42), wherein at least one abutment face (76) is formed on the milling cutter and extends towards the sleeve (42), and wherein the sleeve (42) has a supporting face (78), in particular for supporting on an abutment (10).

Description

technical field [0001] The invention relates to an abutment tool set according to the preamble of claim 1 and to a prosthesis production device according to the preamble of claim 10 . Background technique [0002] Dental restorations combined with implants have been used extensively for decades. The basis is always the implant firmly connected to the patient's jaw, usually by means of a threaded connection. [0003] To provide the actual dental restoration, it has proven expedient to use intermediate structures, so-called abutments, which usually consist of metals, such as titanium, but can also consist of high-strength oxide ceramics , and serves as a connection element to the superstructure, which mostly consists of glass ceramics or feldspar ceramics. [0004] The demands placed on dental restorations produced in this way are high: For example, fatigue strength, even under strong alternating loads, is an important approval criterion, and there are also special requireme...
