Comparative evaluation of frictional resistance of extracoronal attachments of different designs and lengths in fixed partial denture

Aim: The purpose of this study was to evaluate the effects different extracoronal attachment lengths and designs on frictional resistance vertical force required create that in fixed partial dentures (FPD). Setting Design: Finite element analysis. Materials Methods: Four manufacturers were considered for FPD's attachments because their varying length options (3 mm, 3.5 4 4.5 5 mm). Catia V5 software used 3D models samples perform simulations them. To simulate medical facilities, application adjusted take into consideration characteristics. amount calculated by finite analysis using ANSYS workbench 15.0. Statistical Analysis Used: ANOVA Tukey's post hoc test. Results: When compared Panavia SA cements, average microhardness Variolink N resin cements much higher (P 0.001). Compared sorption/solubility statistically substantially lower at 0.05 level.
