PURPOSE The purpose of this impression technique is to overcome the problem associated with restricted mouth opening in association with high arched palate by employing pneumatic impression technique using latex balloon. METHODS A stock tray was modified with auto polymerizing acrylic resin. On the modified tray, a latex balloon was attached with aid of cyanoacrylate. The outlet of the balloo...

BACKGROUND Efficiency in the operating room has become a topic of great interest. This study aimed to quantify the percent use of instruments among common instrument trays across 4 busy surgical services: Otolaryngology, Plastic Surgery, Bariatric Surgery, and Neurosurgery. We further aimed to calculate the costs associated with tray and instrument sterilization, as well as the implications of ...

In this study with the tray-by-tray method an ethane-ethylene rectification column was studied. Therefore, effect of reflux ratio on material cost investigated. case modification diameter and number trays will modify. Not only these parameters, but also required wall thickness for strength determined. investigated between there is second degree polynomial relationship. There a minimum point fun...

in this paper the design, implementation, and evaluation of an experimental-scale potato yield monitoring system is presented. the main objective of this research was to develop a method for accurate mapping of potato yield. at the first stage an instantaneous yield monitoring system was mounted on a potato harvesting machine. this system consisted of a weighing tray, two load cells, a shaft rp...

Introduction Neonates are a particularly vulnerable patient group with complex medical needs requiring frequent radiographic examinations. This study aims to compare computed radiography (CR) and direct digital (DDR) portable imaging systems used acquire chest x-rays for neonates within incubators. Methods An anthropomorphic neonatal phantom was imaged under controlled conditions using one mach...

Although there are several case reports of vital tooth bleaching in children, there is limited clinical trial evidence of the safety or efficacy of this practice. Accordingly, a new clinical trial was conducted to evaluate the effects of 2 different bleaching systems, a 6.5% hydrogen peroxide strip system and a 10% carbamide peroxide tray system, in a population of preteens and teens. A total o...

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 ...
