Production of bone replacement components using in vivo and ex vivo computed tomography and reverse engineering techniques
 
Due to its positive biological properties, carbon (fiber-reinforced plastic, CFRP) represents a potential bone substitute carb in reconstructive medicine. The aim of the investigation described here is to pursue the following objectives:
 
The procedure for processing and manufacturing sponge-like surfaces is to be developed on simple test specimens and adapted to the plastic, which acts as a binder in the fiber composite.
 
Examination of the biocompatibility and bone ingrowth behavior of carbon implants (implants) with different rough surfaces in cancellous bone.
 
Investigations to improve the use of CFRP implants adapted to the individual case by using highly accurate tomographic measurement data of symmetrical healthy bones and reverse engineering methods. In this context, the usual jointing techniques in joints are to be improved by means of methods and methods known from mechanical engineering. Subsequently, the specially adapted carbon implants are to be tested and implemented in an in vivo experiment. Here is a carbon implant with connector bridge a bone defect critical size.
 
In an in-vitro case study, it should be concluded that individually adapted CFRP implants can be developed and manufactured within a very short time by the use of x-ray tomographic methods and reverse engineering techniques.
