Embodiment Construction

[0051] Figures 1 to 17 A first embodiment of an assembly according to the invention is shown having a first type of interface part.

[0052] The assembly is formed by an interface part 1A for dental implants and three auxiliary parts 8A. In the embodiment shown, the three auxiliary parts 8A have the same shape but not the same height: each of them has a different height, so as to be able to cut the abutments of the same interface part 1A at different heights . Figure 1-14 and 16-17 only show the auxiliary part 8A with a smaller height.

[0053] The interface part 1A is a one-piece metal part made of a biocompatible material, such as grade 5 titanium alloy (Ti-6Al-4V alloy), Cr-Co alloy or Ni-Cr-Mo-Ti alloy. Such as Figures 1 to 5 As shown, the interface part 1A has a tubular shape with a central axis Z and comprises a base end 2 for placing the interface part 1A on a dental implant (not shown in the figure), and for placing the prosthetic element (not shown in the figur...

Abstract

The invention relates to an assembly for forming an interface part of a dental implant having a variable height. The assembly comprises a tubular interface part (1A) having a central axis (Z) and an auxiliary part (8A) coupled to the interface part (1A). In coupled position: the auxiliary part (8A) is integrated with the interface part (1A) at least in a direction parallel to the central axis (Z); the final section (14) of the abutment (3) passes through the upper end of the auxiliary part (8A) and the outer peripheral surface (12) of the abutment (3) comprises at least one planar face (13) in a plane (P) intersecting the final section (14) of the abutment (3) and the central axis (Z). The flat face (13) of the auxiliary part (8A) acts as a guide for cutting the abutment (3) at a certain height.

Description

technical field [0001] The present invention is included in the field of dental implants. [0002] A dental implant to which the present invention is applied includes a dental implant surgically implanted into a patient's bone, and a denture fixed to the dental implant by screwing in a screw for this purpose. Set in a threaded hole in a dental implant. Dentures can also be fixed to analogues at the stage of building said prosthesis in the laboratory. An analog is a support with a similar geometry to the connection of a dental implant, and wherein the dental implant structure is fixed such that it can be processed in the laboratory. [0003] This denture, screwed to the dental implant, is a complex element custom made in the laboratory and consists of a prosthetic element such as a castable or denture body and a Interface components between. The interface part protects the dental implant from wear caused by the ceramic material from which the denture is formed and also assi...
