“…The aim was to assess the impact on the marginal fit, fatigue behavior, stress concentration, and fracture load of implant-supported CAD/CAM zirconia crowns. Forty titanium implants were divided into two groups: those with antirotational titanium bases (ARs) and those with rotational titanium bases (RTs). …”

“…The title complex, [Mn(NCS)(2)(C(13)H(19)NO(4))] {systematic name: [3,6,9,12-tetra­oxa-18-aza­bicyclo­[12.3.1]octa­cosa-14(18),15,17-triene-κ(5) N,O,O′,O′′,O′′′]bis­(thio­cyanato-κN)manganese(I­I)}, was obtained by the reaction of MnCl(2)·4H(2)O and NaSCN with pyridino-15-crown-5. The Mn(2+) center has a distorted penta­gonal bipyramidal coordination geometry, coordinated by four O atoms and one N atom of the pyridino-15-crown-5 mol­ecule, and by the N atoms of the two NCS(−) ligands.…”
