In-Vitro Evaluation Of Accuracy Of Conventional And Cad/Cam Removable Partial Denture Frameworks, Pooya Soltanzadeh
In-Vitro Evaluation Of Accuracy Of Conventional And Cad/Cam Removable Partial Denture Frameworks, Pooya Soltanzadeh
Loma Linda University Electronic Theses, Dissertations & Projects
Purpose: Computer-aided design/computer-aided manufacturing (CAD/CAM) technology is gaining popularity in dentistry, and more recently, to fabricate removable partial dentures (RPD). The purpose of this study was 1) to evaluate the overall accuracy and fit of conventional versus CAD/CAM fabricated printed RPD frameworks based on STL data analysis, and 2) to evaluate the accuracy and fit of each component of the RPD framework. Materials and Methods: A maxillary metal framework was designed for a Kennedy class III modification I situation. The master model was scanned and used to compare the fit and accuracy of the RPD frameworks. A total of 40 …
The Wear Of Acrylic Resin And Composite Resin Teeth Against Polished And Glazed Zirconia, Abdulkareem Alshehri
The Wear Of Acrylic Resin And Composite Resin Teeth Against Polished And Glazed Zirconia, Abdulkareem Alshehri
Loma Linda University Electronic Theses, Dissertations & Projects
Background: Excessive wear for the occlusal surfaces of teeth results in decreased masticatory efficiency, poor esthetics and leads to reduced the occlusal vertical dimension which could lead to the development of temporomandibular disorders, consequently, further compromise function. Very few studies have been performed on the wear resistance of zirconia against artificial denture teeth and human enamel. Aim: The purpose of this study was to investigate the influence of polished zirconia (PZ) and glazed zirconia (GZ) on the 2-body wear resistance (vertical substance loss) of seven commercially available denture teeth made of different resins. Material and Method: Eight groups (n=10) of …
