The purpose of this in vitro study was to compare the time efficiency digital chairside and labside workflows with a conventional workflow for single-unit restorations. specific sense defined as time, which has be spent dental office by professional performing relevant steps. A model interchangeable teeth on position 36 created. These were differently prepared, responding several clinical situa...

Background and aims. An ideal root canal filling material should completely seal the entire root canal space and block communication between the root canal system and its surrounding tissues; it should also be nontoxic, noncarcinogenic, non-genotoxic, biocompatible, insoluble in tissue fluids and dimensionally stable. Bonding to dentin is a promising property, which can prevent leakage and impr...

We adopt the notion of von Neumann-Morgenstern farsightedly stable sets to predict which matchings are possibly stable when agents are farsighted in one-to-one matching problems. We provide the characterization of von Neumann-Morgenstern farsightedly stable sets: a set of matchings is a von Neumann-Morgenstern farsightedly stable set if and only if it is a singleton set and its element is a cor...

The polishing step of teeth preparations for crowns is a step often performed, so that there is an increased time during the clinical procedure. The aim of this study is to evaluate the marginal and internal adaptation of all-ceramic CAD/CAM lithium disilicate crowns in polished preparations for crown and nonpolished preparations for crowns. For this purpose, 20 first molars were selected, whic...

OBJECTIVES The purpose of this clinical investigation was to compare a chair-side adhesive all-ceramic system to a laboratory processed adhesive all-ceramic system with respect to quality and time expenditure for the dentist. METHODS The same dentist treated 10 patients, who were each to receive two large posterior single tooth restorations of similar location and extent. One restoration was ...

Objective: The aim of this study was to evaluate the dimensional accuracy Polyvinylsiloxane (PVS) impression materials (Spirias, Imicryl, Konya, Turkey and Variotime, Heraeus, Hanau, Germany) by using stone models after different pouring time (1 hour 24 hours). Methods: A standard maxillary dentulous acrylic model selected as master model. Two linear measurements were on each sample for evaluat...
