STATEMENT OF PROBLEM There is considerable variation in generic formulation and in reported fluoride release from resin-modified glass ionomer luting cements. PURPOSE This study compared fluoride release from 2 generically similar resin-modified glass ionomer luting cements (Vitremer and Advance) with release from 2 conventional glass ionomer luting(More)
PURPOSE This study evaluated the tensile bond strength of a bisphenol glycidyl methacrylate (Bis-GMA) resin luting cement with four different surface treatments of a high Pd-Cu alloy. MATERIALS AND METHODS For each surface treatment type (tin-plated, porcelain furnace oxide, air-abraded, and finished-only), 15 opposing half-dumbbell-shaped samples were(More)
STATEMENT OF PROBLEM Fluoride has been shown to deter caries and has been incorporated into core build-up materials. However, there is considerable variation in the formulation and release of fluoride from core build-up materials. PURPOSE This in vitro study compared the fluoride released by 6 commercially available fluoride-releasing core materials over(More)
This technique allows construction of a detachable custom tray by the dental laboratory before the distal extension RPD framework is returned to the dentist. This permits a framework try-in with unencumbered physiologic relief, rapid attachment of the custom tray, subsequent impression making, and possibly jaw relation records all in one patient visit.
Air sampling for beryllium concentrations produced during finishing procedures for a beryllium-containing alloy was conducted in two rooms with capacities of 700 and 10,000 cubic feet. The clearance rate of beryllium in the air and the effect of ventilation and room size on these concentrations were investigated. With local lathe ventilation, no beryllium(More)
PURPOSE The purpose of this study was to test a new implant system with apically expanding, double-hinged wing stabilizers in dogs before human testing. METHODS Twenty-seven HA-coated endosseous implants were placed in five dog mandibles. The implants were placed into function for 12-weeks after a 12-week healing period. At the end of this period, the(More)
Success in complete-denture treatment is often directly related to the health and condition of the hard and soft tissues that make up the denture-bearing areas. Surgical alteration of the denture-bearing area is frequently necessary to ensure a morphologically correct form capable of providing adequate support for the prosthesis. A number of these anatomic(More)
PURPOSE To evaluate the dimensional stability over time of two visible light-cured indirect inlay/onlay resin composites. MATERIALS AND METHODS Twenty working dies of a Class II preparation were constructed in type IV die stone from impressions of a master metal die. Working dies were randomly divided into two groups of 10 with Class II resin composite(More)
