Additively manufactured water‐washable resin dies cleaned with nonhazardous solutions: Can dimensional and positional trueness be ensured?

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to evaluate the dimensional and positional trueness of additively manufactured (AM) removable dies in water‐washable (WW) resins and cleaned using different post‐processing solutions (98% isopropyl alcohol [IPA], methyl ether solvent [MES], and water).

The Economic Effects of ‘Excessive’ Financial Deepening

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We study the causal implications of high levels of financial deepening for economic development and banking crises in a panel of countries over the past seven decades. We adopt a factor‐augmented heterogeneous difference‐in‐differences estimator and find, in contrast to the existing literature, that very high levels of financial development do
