| Abstract Scope |
Titanium (Ti) remains the most widely used metal in biomedical applications due to its biocompatibility. In particular, Ti-based plates are generally used to built-up craniofacial prosthesis and replace the bone. However, the significant difference of the mechanical properties between Ti and the surrounding tissues results in stress shielding which is detrimental for load bearing tissues. To attenuate this effect, a process with the elaboration of sandwiches materials was developed.
In previous works, we aimed to employ surface-confined poly(methyl methacrylate) (PMMA) layers as adhesives to stick the polymer core (PMMA) on the metallic skins (Ti) to design resin-free sandwiches (SMS) by pressing the three components together above the glass transition temperature (Tg = 105°C) of the PMMA. To improve formability of the implants, a new strategy is proposed where the PMMA is replaced by a copolymer PMMA/PBMA (poly(butyl methacrylate)). |
