The article reports on a patient who required a cranial protection system.Using additive
manufacturing techniques and surgical planning with the help of bio-models, a patient-specific bone
implant solution was proposed that allows aesthetic restoration of the affected area and provides
an adequate level of protection. In addition, through a comparative analysis with finite elements,
the mechanical response to external actions of the medical device, printed with two materials:
polymethylmethacrylate (PMMA) and polyether-ether-ketone (PEEK), is simulated. The tested
materials have recognized biocompatibility properties, but their costs on the market differ significantly.
The results obtained demonstrate the similarities in the responses of both materials. It offers the
possibility that low-income people can access these devices, guaranteeing adequate biomechanical
safety, considering that PMMA is a much cheaper material than PEEK.
