Objective: This study evaluated the polishing properties of occlusal splint materials obtained using subtractive and additive manufacturing methods with laboratory-type (LP) chairside-type (CP) procedures. Material Methods: Specimens (N=180, n=60 each group) were manufactured one following methods: method (SMM) (M-PM Disc, Merz Dental GmbH), (AMM) (Freeprint Splint 2.0, DETAX GmbH & Co. KG)...

The objective of this study was to identify differentially expressed genes in the mechanically unloaded rat heart by suppression subtractive hybridization. In male Wistar-Kyoto rats, mechanical unloading was achieved by infrarenal heterotopic heart transplantation. Differentially expressed genes were investigated systematically by suppression subtractive hybridization. Selected targets were val...

PURPOSE The purpose of this study was to verify the clinical-feasibility of additive manufacturing by comparing the accuracy of four different manufacturing methods for metal coping: the conventional lost wax technique (CLWT); subtractive methods with wax blank milling (WBM); and two additive methods, multi jet modeling (MJM), and micro-stereolithography (Micro-SLA). MATERIALS AND METHODS Thi...

Purpose This in vitro study aimed at ascertaining the retention forces for telescopic crowns fabricated with Selective Laser Manufacturing (SLM) and Sintering (SLS) additive technologies, Computer Aided Design – (CAD–CAM) subtractive technology, by using suitable materials each.

ABSTRACT We exploit a sample of 80 000 Sloan Digital Sky Survey central galaxies to investigate the effect active galactic nucleus (AGN) feedback on their evolution. trace demographics optically selected AGN (Seyferts) as function internal properties and environment. find that preeminence dominant ionizing mechanism increases with stellar mass, overtaking star formation for Mstellar ≥ 1010 M⊙. ...

concentrations of elements (as, co, cu, ni, mo, pb, v, cd, cr and zn) are studied in the surface sediments of bakhtegan lake, northwest of nyriz city, iran, to assess metal contamination. the average abundance order of trace elements content in bakhtegan lake sediments is cr>ni> v> zn> cu> co> as> pb> mo>cd. the comparison of trace elements concentration in bakhtegan lake sediments with toxicol...
