Analysis of compressive strength of occlusal splints manufactured with three liquid resins at three angles of orientation on 3D printer

The aim of this study is to analyze the compressive strength occlusal splints manufactured with three different liquid resins in a 3D printer and angles orientation. used here are (n=12): Resilab Clear (Wilcos do Brasil, Petrópolis, RJ, Brazil), Prizma Smart Print Bio (Makertech Labs, Tatuí, SP, Cosmos Splint (Yller Biomateriais, Pelotas, RS, Brazil); each resin group divided into subgroups according orientation manufacture: 0, 45 90 degrees. A dental manikin was scanned file manufacture steel hemiarch model. This model design as basis for tests. were designed flat surface minimum thickness 2 mm. test performed constant force 200N, velocity 0.5 mm/min, along entire until fracture. Results show no difference between resins, regardless manufacture. showed intragroup effect Clear; larger samples at degrees than 0 degree. 90-degree intermediary from other angles. shows that had similar behavior terms strength, except resin, where plates degree worse those
