A customizable implant made of plastic including a thermoplastic which is reinforced with long fibers arranged multidirectionally in a targeted manner and has a modulus of elasticity E of 10-70 GPa is provided. A system for producing a customizable implant including a device for collecting patient data regarding the environment into which an implant is to be inserted, a computer program for creating a model for a customized implant based on the patient data collected, and a device for producing the customized implant based on the calculated model by means of 3D printing and/or laser sintering is also provided.

Implant made of fibre-reinforced plastic

The invention relates to an implant preform made of plastic, which comprises an assembly of at least one biocompatible&#x2014;being intended for contact with a biological material&#x2014;thermoplastic plastics unit (A) having an elasticity modulus Eand at least one thermoplastic plastics unit (B) having an elasticity modulus E, where for the elasticity moduli of these plastics units E&#x3c;E, and the plastics units in their assembly zone are seamlessly connected thermally to one another. The invention also relates to the production of the implant preform made of plastic and also to the use of the implant preform as an implant or for fabrication of an implant therefrom, more particularly to the use thereof as a dental implant or for fabrication of a dental implant. The invention can also be applied to other bone implants.

Production of semifinished goods for implants based on plastic

The invention relates to a metallic implant, which has vitreous-crystalline bioactive material on the surface thereof. According to the invention, a metallic implant base body arranged on the surface of the particles has a bioactive, vitreous-crystalline material consisting of 15-45 wt. % CaO, 40-45 wt. % PO, 10-40 wt. % ZrOand 0.7-3.5 wt. % fluoride, having apatite and calcium zirconium phosphate as main crystalline and a glass phase as an auxiliary component. Said vitreous crystalline material contains at least 35 wt. % main crystal phases and at least 5-15 wt. % auxiliary compounds. All of the percentage data is expressed in relation to the total weight of the vitreous crystalline material and the particle size of the vitreous crystalline material is between 60-350 &#x3bc;m.

Surface treated metallic implant and blasting material

The invention relates to a method for the production of an adhesive and an adhesive kit for joining similar or different metal surfaces or ceramics, especially in the field of biomedicine. The objective of the invention is to avoid polymerization-linked by-products and disadvantageous effects, in addition to enabling a temporary biocompatible bond between metal and metal or metal and ceramics. The inventive method consist in using a monomer-free polymethylmethacrylate which is mixed with a suitable, non-toxic solvent and a bioactive vitreous-crystalline material with a particle size ranging from 0.05&#x2013;20&#x3bc;, consisting of 15&#x2013;45 wt. % CaO, 40&#x2013;45 wt. % PO, 10&#x2013;40 wt. % ZrOand 0.7&#x2013;3.5 wt. % fluoride, having apatite and calcium zircon phosphate as main crystal phases and a glass phase as an auxiliary component until a flowable mixture is obtained. The invention also relates to an adhesive kit consisting of said components. Sufficient amounts of resistance are obtained for a temporary bond, enabling the bond to be neutralized when desired.

Temporary adhesive for metal-metal and metal-ceramic bonds

A method for producing a bioactive bone cement and a bone cement kit for anchoring artificial joints and for filling out bone defects. The method avoids polymerization-linked by-products and disadvantageous effects, while at the same time providing the bone cement with long-term stability. The inventive method uses a monomer-free polymethylmethacrylate, which is mixed with a suitable non-toxic solvent, and a bioactive, vitreous-crystalline material with a particle size ranging from &#x3e;20 to 200 &#x3bc;m, having 15&#x2013;45 wt. % CaO, 40&#x2013;45 wt. % PO, 10&#x2013;40 wt. % ZrOand 0.7&#x2013;3.5 wt. % fluoride, having apatite and calcium zircon phosphate as main crystal phases and a glass phase as an auxiliary component until a flowable mixture is obtained. The invention also relates to a bone cement kit having said components.
