AIM The aim of this study was to compare the accuracy of the angle made by Frankfort horizontal plane-occlusal plane on maxillary casts, mounted using the respective facebows on Artex Amann Girrbach and Hanau Wide-vue semi-adjustable articulators with cephalometrically derived Frankfort horizontal plane-occlusal plane angle as a control. SUBJECTS AND METHODS Maxillary casts of 30 subjects wer...

BACKGROUND The use of an oscillating saw for cast removal creates a potential for iatrogenic injury and patient discomfort. Burns and abrasions can occur from the heat created by frictional forces and direct blade contact. With use of a cadaver model system, skin temperature measurements were recorded during cast removal with an oscillating saw. METHODS Casts of uniform thickness were applied...

The Effect of Equilibrating Master Casts On The Occlusal Harmony Of Cast Restorations (October 2008) Joe Meng, University of Montana; D.D.S., University of Iowa Chair of Advisory Committee: William W. Nagy PURPOSE: To determine the occlusal accuracy of mounted stone casts and the viability of a cast adjustment technique. MATERIALS AND METHODS: A dentoform mounted on an articulator served as the...

Objective: The disinfection of dental stone casts using microwave radiation has been shown, but doubts remain regarding its efficacy under various conditions. The aim of the present study was to evaluate the efficacy of microwave disinfection on wet and dry dental stone casts contaminated by a resistant microorganism. Material and methods: In this in vitro study, 34 stone half-casts were prepar...

PURPOSE: To evaluate the effect of various implant-level impression techniques on the accuracy of definitive casts for a multiple internal connection implant system with different implant angulations and subgingival depths. MATERIAL AND METHODS: Six tapered Screw-Vent implants were placed in a reference model with different angles (0, 15, and 30 degrees) and subgingival positions (0, 1, and 3 m...

BACKGROUND Federal guidelines and state laws mandate that all children must be appropriately restrained while traveling in motor vehicles to reduce the risk of injury and death secondary to motor vehicle accidents. The purpose of this study is to identify the methods of restraint in motor vehicles for children in hip spica casts. METHODS Children placed in hip spica casts between August 1, 20...

BACKGROUND This study evaluated the survival of the most prevalent oral bacteria and fungi (Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli, and Candida albicans) in dental casts, and compared changes in the amounts of these microorganisms at different time intervals to determine how long dental casts may pose threat to the health of dental personnel and patients.
