Comparison of Impact Resistance on a Knitted Prosthesis Based on Polypropylene and Acrylic Cements Based on Poly(methyl methacrylate)

Abstract

The aim of the study was to compare the physical and mechanical properties of known prostheses for cranioplasty: knitted Codubix based on polypropylene and Modela-cryl resin based on PMMA. It was expected that the study would allow to check whether it is possible to combine their properties, which should enable the preparation of a new material with properties combining the best features of both components. Physico-chemical and mechanical properties were evaluated. It was found that the two materials meet the requirements for chemical purity, ensuring the safety of their use. Regarding the mechanical properties, the energy of impact diffusion for two types of prostheses was determined applying the Drop Tower technique. The polymerisation heat of Modela-cryl resin was determined in real time using the DSC technique.
