摘要:
Package (1) for an implant (2), in particular for a dental implant, comprising a housing (5) with a compartment (51) that can be closed by way of a pivotable and/or slidable cover (4) so as to be essentially liquid-tight, said compartment being intended for a first section (2′) of the implant (2), and an area (19) for a second section (3) of the implant (2), said area being separated rated from the compartment (51) by way of a housing wall (8), wherein a passage (35) connecting the compartment (51) and said area (19) is provided in the housing wall (8) for a transition section (3′) between the first section (2′) and the second section (3) of the implant (2), and wherein the housing wall (8) comprises a removal slot (9, 36) for removal of the implant when the cover (4) is open without separating the sections (2, 3). The package (1) comprises at least one fluid cartridge (12) and an associated release element (18) and the fluid cartridge (12) can be opened by way of the release element (18) when the cover (4) is closed such that fluid located in the fluid cartridge (12) can flow out into the compartment (51).

摘要:
The invention relates to a device (1) for the amelioration of a recess (8), e.g. a recess in a (human) bone (7). The device comprises an element (2) for producing or coupling mechanical energy, and a cylindrical collar (4) comprising a cylindrical lateral surface having an outside diameter and having a central recess (26) for accommodating a guide pin (3). The guide pin (3) is provided to be inserted substantially down to the base of the recess (8) before applying oscillations, and in the region of the end thereof facing the base of the recess it is surrounded by an amelioration sleeve (6) made from a material that can be liquefied by way of ultrasonic oscillations. The cylindrical lateral surface of the amelioration sleeve (6) substantially has the same outside diameter as the collar (4), and the guide pin (3) is accommodated in the central recess (26) in a displaceable manner such that the collar (4) upon applying ultrasonic oscillations can be displaced relative to the guide pin (3) in the direction toward the base of the recess (8) while liquefying and laterally and/or longitudinally displacing the material of the amelioration sleeve (6).
摘要:
The invention describes a device (1) for the amelioration of a recess (8), particularly a recess in a porous material or (human) bone (7). The device comprises an element (2) for producing or coupling mechanical energy, such as ultrasonic oscillations, and a cylindrical collar (4) comprising a cylindrical lateral surface having an outside diameter and having a central recess (26) for accommodating a guide pin (3), wherein the guide pin (3) is provided to be inserted substantially down to the base of the recess (8) before applying oscillations, wherein the guide pin (3) in the region of the end thereof facing the base of the recess is surrounded by an amelioration sleeve (6) made from a material that can be liquefied by way of ultrasonic oscillations, wherein the cylindrical lateral surface of the amelioration sleeve (6) substantially has the same outside diameter as the collar (4), and wherein the guide pin (3) is accommodated in the central recess (26) in a displaceable manner such that the collar (4) upon applying ultrasonic oscillations can be displaced relative to the guide pin (3) in the direction toward the base of the recess (8) while liquefying and laterally and/or longitudinally displacing the material of the amelioration sleeve (6). The invention further describes elements of such a device, and sterile packages having such elements, and methods for the amelioration of recesses in bones, such as jaw bones or spine elements.
摘要:
A metal implant, in particular a dental implant, with a hydrophilic surface for at least partial insertion into a bone, and a method for the production of said implant are described. A particularly advantageous hydrophilic surface for improved osteointegration properties is made available if it is briefly treated, at least in some areas, in a weakly alkaline solution. These excellent osteointegration properties can be achieved in a method in which, optionally after a preceding mechanical surface modification by material removal and/or chemical surface modification, at least the areas exposed of this surface exposed to bone and/or soft tissue are chemically modified in an alkaline solution.
摘要:
What is described is an implant that comprises a coating, at least in areas, in the implanted state in the surface areas that are at least directly in contact with skin and/or soft tissue. The implant is preferably characterized in that the coating comprises both a statin, such as simvastatin, in the hydrolyzed or unhydrolyzed form, or pharmaceutically compatible salts thereof, as well as at least one other component selected from the group consisting of branched or linear, substituted or unsubstituted, saturated or partially unsaturated C10-C30 alkyl, alkenyl, alkylaryl, aryl, cycloalkyl, alkylcycloalkyl, alkylcycloaryl amines or mixtures thereof and/or at least one water-soluble ionic polymer component. A method for production such an implant is also described as well as a composition that can be used in such a method.
摘要:
A bioactive surface layer that is particularly suited for medical implants and prostheses. A variable portion of the 0.1 to 50.0 μm thick, porous surface layer includes calcium phosphate phases. The surface layer contains amorphous or nanocrystalline calcium phosphates and the pore density on the surface of the surface layer ranges from 104 to 108 pores/mm2. The ratio of Ca/P over the entire surface layer ranges from 0.5 to 2.0. The surface layer has a high solubility so that it can act as a contributor of calcium phosphate for the formation of bone.

摘要:
The invention relates to a dental implant, which comprises a coating at least in those surface areas that come into contact with hard and/or soft tissue when implanted. To ensure that the active ingredient contained in the coating (bisphosphonate) is released into the surrounding tissue or can act in the latter in a controlled manner at the correct speed, the coating is characterized in that it contains bisphosphonate, the respective pharmaceutically compatible salts or esters of the latter, in addition to at least one amphiphilic component, selected from the group containing branched or linear, substituted or unsubstituted, saturated or partially unsaturated C10-C30 alkyl-, alkenyl, alkylaryl-, aryl-, cycloalkyl-, alkylcycloalkyl-, alkylcycloaryl-carboxylates, -phosphates or -sulfates or mixtures thereof and/or a water-soluble ionic polymer component. The invention also relates to a method for producing a dental implant of this type and to a specific composition, which can be used to produce a coating of this type.
