PURPOSE The accuracy of master cast reproduction by a polyvinylsiloxane impression material using two visible-light-curing resin and an autopolymerizing polymethyl methacrylate resin custom tray materials was investigated. MATERIALS AND METHODS Custom trays were fabricated from a master cast that had three index points marked on both the inner and outer vestibules. Impressions were made of th...

Introduction : Implantology is the fastest growing specialty in dentistry. A key point for accurate fabrication of fixed prosthetic structures taking an impression field. The implant-prosthetic restoration masticatory apparatus after composition function and aesthetics dentition through digital technology gaining wider popularity. Aim purpose this article to address materials compare two method...

Prosthodontic rehabilitation for an acquired maxillary defect begins immediately at the time of surgical resection. Abrupt alteration of physiologic functions such as speech, mastication, deglutition, and salivary control associated with ablative surgery requires timely prosthetic intervention. Prosthetic rehabilitation begins with a surgical obturator, which is inserted at the time of surgery ...

OBJECTIVE To compare, in vitro, the accuracy between dental stone casts obtained from the first and the second pour using metallic (Smart) and plastic (Triple Tray) dual-arch trays. MATERIAL AND METHODS The impressions were taken using Flexitime® vinyl polysiloxane from a typodont model with a mandibular right first molar prepared for a full crown. Ten impressions were made with each tray and...

Previous research has identified Campylobacter as one of the leading causes of foodborne illness. Poultry and poultry products have been identified as a major source of Campylobacter in human infections. Although many risk factors that contribute to Campylobacter levels have been identified, precise identification of the most effective sites for intervention has not been established. Epidemiolo...

In comparison to single-analyte devices, multiplexed systems for a multi-analyte detection offer reduced assay time and sample volume, low costs high throughput. this work, multiplexing platform an automated quasi-simultaneous characterization of multiple (up sixteen) capacitive field-effect sensors by the capacitive-voltage (C−V) constant-capacitance (ConCap) mode is presented. The were mounte...

Nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. It is almost used as a first and the most applicable choice in separation methods. In this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. The study was carried out by using a 3-D...

This is the first study to examine effect of three different cultivation methods (bottom-tray culture, suspended-tray and beach/bottom culture) on growth survival rates snout otter clam, Lutraria philippinarum, after 12 months grow-out from seed commercial size. Analyses included weight, survival, shell size, total fat. Although results showed limited differences in among methods, were signific...
