Original abstract
Medical grade 3D printing offers the possibility to manufacture patient-specific implants to treat cranial defects. The performance of the implant assembly depends on many factors, such as material, thickness, size and manufacturing accuracy. A significant factor in the stability and success of the assembly is the fixation method. Cranial implants are usually fixed to the skull by means of mini-plates. Biomechanical assessment of fixing the implant to the skull might be helpful not only for mini-plate design but might be beneficial also for the surgeons. In this study, four different mini-plate designs were analyzed and compared based on the stress-strain analysis of one cranial implant fixed at three locations by mini-plates. Computational simulations were done using Finite Element Method.

3D tisk nabízí možnost výroby implantátů například k léčbě defektů lebky tzv. individualistickým přístupem. Mechanické vlastnosti implantátu závisí na mnoha faktorech, jako je materiál, tloušťka, velikost a přesnost výroby. Dalším významným faktorem je způsob uchycení implantátu v lebce pomocí fixátorů. Kraniální implantáty jsou obvykle fixovány na lebku pomocí mini-destiček. Biomechanické posouzení fixace implantátu na lebku by mohlo být užitečné nejen pro konstrukci mini-destiček, ale mohlo by být prospěšné i pro chirurgy. V této studii byly analyzovány čtyři různé fixační destičky a porovnány na základě analýzy napětí a deformace. Výpočtové simulace byly provedeny metodou konečných prvků.
