PURPOSE Calcium phosphate cement is a bioactive and biodegradable grafting material in the form of powder and liquid, which when mixed, sets as primarily hydroxyapatite, sometimes mixed with unreacted particles and other phases. This material has been extensively investigated due to its excellent biological properties, potential resorbability, molding(More)
The results of a long-term clinical study of a posterior composite resin are reevaluated using the Moffa-Lugassy, the Vivadent, and the Leinfelder-Goldberg standards. Occlusion (ICI/Coe, England) was selected for the study, and the results obtained from three universities are compared. From these results, it is concluded that all posterior composite resins(More)
This article describes the dental rehabilitation of a bulimic patient using endosteal implants. Although the patient, a 31-year-old woman with a long history of bulimia nervosa, had been receiving medical and psychological treatment, the condition was not completely controlled. Clinical examination revealed multiple crowns with extensive cervical caries.(More)
Interim restorations are vulnerable to inadvertent fracture during mastication. Autopolymerizing acrylic resins have traditionally been selected for fabrication of provisional restorations. Triad light-polymerizing tooth-colored acrylic resin was recently introduced as an alternative material for this procedure. This material does not contain methyl(More)
This investigation was conducted to determine the effects of an air-abrasive polishing system on various implant surfaces. Four each of the following types of implants were obtained from the manufacturer: Stryker DB (a titanium alloy implant), Denar Steri-Oss (a pure titanium implant), IMZ (pure titanium polished collar/plasma-sprayed body), and IMZ(More)
BACKGROUND Two important factors in the use of implant-retained overdentures are cleansability and patients' satisfaction. Limited research has been published concerning the cleansability of these overdentures On the other hand, studies have compared patients' satisfaction with conventional dentures and various designs of implant overdentures. However, no(More)
This study was done to determine the efficacy of rapidly mixing zinc phosphate cement in conjunction with fixed prosthodontic procedures. Properties measured included rate of pH change and temperature increase, film thickness, and setting time. The rapid mix technique in conjunction with the frozen glass slab resulted in a faster elevation of the pH but(More)
