Abstract

The aim of this study is to investigate the mechanical properties of polymethyl methacrylate (PMMA) and thermoplastic polycarbonate (TPC) materials in order to produce night bruxoguards. For this purpose we used a static tensile test. In the next step the microstructures of PMMA and TPC were observed. Within this framework special attention was paid to the examination of the tensile-test tube fracture surfaces for both materials. This approach revealed that PMMA is a brittle and TPC is a plastic material. Certain mechanical properties and a review of the crucial areas confirmed that the TPC material is extremely favourable for making occlusal splints.

Secondary title: Mehanske lastnosti materialov za nočne zobne ščitnike
Secondary abstract: Namen te študije je preiskava mehanskih lastnosti polimetil metakrilata (PMMA) in termoplastičnega polikarbonata (TPC) za izdelavo nočnih zobnih ščitnikov. Za ta namen je bil uporabljen statični natezni preizkus. V naslednjem koraku je bila preiskana mikrostruktura PMMA in TPC. Posebna pozornost je bila namenjena preiskavi površine preloma na ceveh za natezni preizkus, izdelanih iz obeh materialov. Tako je bilo ugotovljeno, da je PMMA krhek material, TPC pa plastičen. Nekatere mehanske lastnosti in pregled ključnih področij potrjujejo, da je za izdelavo okluzalne opornice izredno primeren material TPC.
