A Comparison of Processing Properties of Anatomic Facsimile Models (AFM) of the Temporal Bone with Original Human Bone Structures. Issue 7 (29th March 2016) - Hahne, Cornelia
Abstract : Due to a limited availability of human bone for training purposes in ear surgery, authentic models are needed. The Magdeburg temporal bone model (Mtbm) is an epoxy resin facsimile of a human os temporale which is manufactured by 3D printing based on human computed tomography data. Here, the processing properties of the Mtbm are investigated with respect to the drilling and milling behavior and the elastic modulus. Results are compared with those of human os temporale. The forces during drilling and milling and the elastic moduli show significant differences between both types of material – all values are significantly higher for bone. However, reproducing the trabecular structure of human bone results in a similar degree of force fluctuations. Thus, an authentic feeling for the surgeon is roughly provided by the AFM. Abstract : The Magdeburg temporal bone model is an epoxy resin facsimile of human os temporale, manufactured by 3D printing for training purposes in ear surgery. This study investigates the processing properties in drilling and milling as well as the elastic modulus of the model in comparison to human os temporale.
