Nowadays, in the field of dental prosthetics, numerous solutions can be adopted in terms of implant design, and it is of fundamental importance to be aware of their mechanical properties in order to assess their clinical reliability. In the present study, a characterisation of the mechanical properties of different dental resins was carried out, including ceramic-polymeric hybrid, 3D-printed, flowable and ceramic materials. Nanoindentation tests were performed before and after artificial ageing processes (to which all samples were subjected). Ceramic materials were sintered separately at 1500, 1550 and 1600°C, in two different furnaces, individually or in groups and the influence of these parameters were mechanically characterised.
