Abstract
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.
Claims12
A single component implant made of a plastic material, comprising a homogenous thermoplastic material which is reinforced with targeted multidirectionally arranged long fibers and has a modulus of elasticity E of 30-50 GPa, wherein the reinforcing fibers have a diameter of 4 to 10 μm and the targeted multidirectional arrangement of the fibers is calculated based on patient data collected, wherein the collected patient data include at least one of:
- the force applied under mechanical stress, the bone density, or the spatial structure of the environment into which an implant is to be inserted.
