Abstract: The invention relates to implants that are implanted into living beings as temporary implants and that disintegrate in the body through biological adsorption over a period of time, in addition to a process for producing aforesaid implants. The implant according to the invention consists of magnesium or a magnesium master alloy. It is formed from fibers of magnesium or a magnesium master alloy that are connected to one another through sintering bridges that are locally spaced vis-à-vis each other and form an open-pored body. The fibers may be produced with the help of the melt extraction process and may subsequently be sintered with one another.

Abstract: A method for manufacturing a bioresorbable implant, wherein a magnesium alloy is formed into an implant. A melt is pressed into a die and gases in the die induce turbulence in the inflowing melt, thereby enclosing gas, so that the porous implant is formed with a porosity, which increases from outside inwardly. The surface of the implant is substantially free from open pores.

Abstract: In a preferred embodiment of the invention, an interface attachment device which is customized on one side for placement on a patient's tooth surface and locked on to the bottom or base of a bracket on the other side is disclosed. The combination of the interface attachment device and the bracket is bonded to the surface of a tooth for an orthodontic treatment of the patient. One or more interface attachment devices, with or without brackets, can be precisely placed and bonded to the corresponding surfaces of one or more teeth of a patient using a tooth attachment placement device created for the patient. The locking mechanism between the interface attachment and the bracket can be (a) form-locked, i.e. male/female arrangement, (b) friction-locked (i.e. using spring, magnetism, shape memory phase shift, shrinkage, etc.), (c) combination of (a) and (b), or (d) any other type. The interface attachment can be attached to the tooth surface by any kind of adhesive or composite material.

Abstract: An antibacterial coating that is composed of silver is disclosed, as well as medical tools and implants comprising such a coating, and a method and an apparatus for the production of such a coating. The medical tools or the dental or orthopaedic implant comprises a metal or metal alloy having a treated surface wherein the treated surface is at least partially converted to an oxide film by plasma electrolytic oxidation using a colloid-dispersed system and wherein the converted surface is partially covered by islands formed by colloid-dispersed silver-particles of the colloid-dispersed system. An Ag—TiO2 coating shows excellent properties in terms of antibacterial efficacy (even against multi-resistant strains), adhesion and biocompatibility. The life-time of an implant in a human body is increased. The antibacterial coating can be used in the field of traumatology, orthopaedic, osteosynthesis and/or endoprothesis, especially where high infection risk exists.
