Embodiment Construction

[0021] In these figures, a dental implant or similar implant comprises a metallic core 1 and a ceramic outer (sheath) layer 2 surrounding the core 1 at least partially. The ceramic outer (sleeve) layer is composed of a zirconia sleeve 2 obtained by molding. After obtaining the sleeve, it is embedded on the core 1 and fixed on the core by gluing.

[0022] A space J is provided between the facing corresponding surfaces of the core 1 and the sheath 2 so as to form reservoirs 3 therebetween for receiving the adhesive.

Abstract

The invention concerns a dental implant or prosthetic component. Said implant comprises a metallic core (1) and an outer ceramic sleeve (2) enclosing at least partly the core (1), both being assembled together by bonding. The outer ceramic layer consists of a sleeve (2) separate from the core (1), nested thereon by sliding and fixed by bonding, by providing therebetween a resist (3) for the adhesive with sufficient volume to absorb the impacts to which the implant is subjected but without inducing a significant clearance between the core (1) and the ceramic sleeve (2).

Description

technical field [0001] The invention relates to the field of medicine, in particular to the field of dental implants. The subject of the invention is a dental implant or prosthesis component comprising a metallic or synthetic material framework and a ceramic sheath. Background technique [0002] It is known for use as a dental implant inserted at least partially into a bone socket. In order to make these implants have both sufficient mechanical strength and biological compatibility with the patient's organic tissue, it is proposed to combine a strong metal core with a shell or a ceramic jacket through the living body. together. This type of method mainly refers to the following patents: FR2778091 (BENHAMOU), DE2419080 (KIRSCHNER), FR2745998 (PROSIS), FR2693900 (PROSIS), US4713006 (HAKAMATSUKA), US5310343 (HASAGAWA) and EP0405556 (TDK). [0003] One problem that needs to be solved is the connection between the core and the ceramic jacket. According to a first technique, i...
