In recent years, mold manufacturers have had to meet growing demand for high precision molds, low cost and short delivery time due to the miniaturization of finished products, price competition with overseas companies, and reduced model cycles. In line with these market changes, users have been gradually inclined to shift their machining methods applied to key mold parts (made of hardened steel...

Purpose. To utilize proteomics to discover proteins associated with significant cardiac magnetic resonance imaging (MRI) changes in marathon runners. Methods. Serum from 25 runners was analyzed by surface enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF-MS). Proteomic profiles were compared in serum samples obtained prior to the race, at the finish line and withi...

Introduction. One of the main steps of impression is the selection and preparation of an appropriate tray. Hence, the present study aimed to analyze and compare the accuracy of one- and two-stage impression techniques. Materials and Methods. A resin laboratory-made model, as the first molar, was prepared by standard method for full crowns with processed preparation finish line of 1 mm depth and...

4 SUMMER/FALL 1999 T’S A RACE with no starting point, no fixed course, and really no rules at all: walk, run, ride, do anything you want. Form a team, as big as you like. Build any sort of machine you wish with whatever money you can get your hands on. Just get to the finish line first. That finish line isn’t a particular place but a new understanding of a symmetry (or rather, an almost symmetr...

OBJECTIVES To investigate if general dental practitioners (GDPs) in private practice in Jordan follow universal guidelines for preparation of anterior teeth for resin bonded all-ceramic crowns (RBCs). MATERIAL AND METHODS A sample (n=100) of laboratory models containing 208 tooth preparations for IPS Empress and In Ceram, featuring work from different GDPs, was obtained from 8 commercial dent...
