Abstract:
The present invention relates to a one-part implant (1) for attachment of artificial teeth comprising an anchoring part (5) and a mounting part (20), whereby the anchoring part (5) and the mounting part (20) are configured in one piece. The anchoring part (5) of the one-part implant (1) has a bone contact surface B and a soft tissue contact surface S. The soft tissue contact surface S is at least partially hydroxylated or silanated, which results in an improved soft tissue integration.
Abstract:
PROBLEM TO BE SOLVED: To provide an abutment with a hydroxylated surface.SOLUTION: The present invention relates to the abutment (1) of a dental implant system. The abutment (1) has at the top a support region intended for receiving a prosthetic build-up construction and at the bottom an implant contact region intended for insertion into the receiving hole of an implant, whereby the abutment (1) has between the support region and the implant contact region a soft tissue contact surface (11). The soft tissue contact surface (11) is at least partially hydroxylated by a hydroxyl group present in the outermost atomic layer of the abutment surface, and is hydrophilic.
Abstract:
PROBLEM TO BE SOLVED: To provide an implant having improved surface characteristics and excellent biocompatibility, and a method of manufacturing the implant.SOLUTION: The implant includes attaching means 9.12 to be attached to the living body tissue of a human or an animal. The implant has an outer surface including a first part and a second part having different characteristics in biocompatibility with the living tissue, and has at least one surface part 20 including a polished surface 21 constituting the first part and one or more sectioned regions 22, 23, 24, 25, 26, 27, 28, 29, 30 and 31 constituting the second part. A masking unit for a method of manufacturing the implant, in which a perforated masking unit is applied to the implant, is also provided.
Abstract:
The present invention relates to a process for fabricating a porous coatings with controlled structure in the micro and nano-size domain. In particular, but not exclusively, it relates to a process for fabricating coatings with an anisotropic pore size distribution and to coatings obtained using such coatings. It describes in particular the use of ink-jet method to deposit in a controlled way such coatings. It also relates to porous coatings with controlled structure in the micro and nano-size domain. The coating has a thickness between 10 nanometers and 10 millimeters and its porosity is created in such a way that the pore size distribution is anisotropic. It finally describes objects covered with this coating.
Abstract:
PROBLEM TO BE SOLVED: To provide a layer, which is arranged on implant for bone or tissue structure, and intended to construct a boundary or a barrier between the implant body and the structure for reinforcing retention, and has a substantial thickness, and to provide an implant having the layer. SOLUTION: A layer 2''' is arranged on an implant 1'' for bone or tissue structure 5. The layer constitutes a boundary or barrier between the actual or unoxidized body 1'' of the implant and the structure for the purpose of increasing retention and has, in this context, a substantial thickness T'. The layer is designed with a channel network 6 which gives the layer a substantial porosity. The channel network is designed with mouths 3' 4' which face towards the structure and whose respective cross-sectional diameters D, at the surface 2a' of the layer facing towards the structure 5, are substantially less than the respective extents (e.g. H) of the channels in and down into the layer as seen from the surface 2a'.

Abstract:
Dental implant with a part for anchoring in bone and a mounting part taking an element to be applied is made in one piece from a material based on zirconium oxide. The surface of the anchoring part, at least, is (partly) pretreated by a subtractive attrition or provided with a coating that promotes ossification. Independent claims are also included for the following: (1) Kit with a sealable container with a liquid, preferably water, for holding the implant; (2) Production of the implant by making the implant in one piece and pretreatment by subtractive attrition or providing a coating to promote ossification.
