The Effect Of Root Canal Cleansing On The Retention Of Glass Fiber-Reinforced Posts, Faisal Dhaifallah Al-Qarni
The Effect Of Root Canal Cleansing On The Retention Of Glass Fiber-Reinforced Posts, Faisal Dhaifallah Al-Qarni
Loma Linda University Electronic Theses, Dissertations & Projects
Esthetic glass fiber-reinforced posts are being used more often. The most commonly reported complication associated with these posts is debonding. Dentine conditioning with solutions such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass fiber-reinforced posts, when cemented with self-adhesive resin cement. Forty-five (n=15) extracted human premolar teeth were sectioned at the cemento-enamel junction to obtain root length of fifteen millimeters. Endodontic …

Perspectives For Titanium-Derived Fillers Usage On Denture Base Composite Construction, Nidal Elshereksi

Poly(methyl methacrylate) (PMMA) is an extensively used material in dentistry because of its aesthetics, processability, and reparability. However, PMMA is still far from being ideal in fulfilling the mechanical requirements of prosthesis. PMMA-based denture base polymers exhibit low fracture resistance and radiopacity behavior. Efforts to improve the mechanical and radiopacity properties of denture base materials through inclusion of silica-based fillers are ongoing. Although silane-treated siliceous fillers are commonly used, they are not sufficiently strong.They also exhibit cracks, which either cut through the glass fillers or propagate around the filler particles. This defect occurs when the dental composites are placed in …
Comparing The Vertical Misfit Of Casts Produced By Two Verification Jigs, Abdulaziz Saeed Alqahtani
Comparing The Vertical Misfit Of Casts Produced By Two Verification Jigs, Abdulaziz Saeed Alqahtani
Master's Theses (2009 -)
Purpose: To compare the dimensional accuracy between master casts fabricated with verification jigs made of acrylic resin and light cure Triad. Materials and Methods: 10 GC Pattern resin Pattern verifications jigs and 10 Triad gel verification jigs fabricated of a master cast of a mandibular model of 4 internal hex implants. A stone base was fabricated for each verification jig. One screw test was used to evaluate the vertical gap at the terminal abutment using a digital micrometer with an accuracy of 1μm to record the vertical gap for each sample. Results: Triad Gel group has the lowest average distortion …
Radiographic Evaluation Of Accuracy Of Surgical Stent For Implant Placement In Knife Edge Posterior Mandibular Ridge In Cases Of Ridge Splitting, Fardos N. Rizk, Engy Abdelhamed
Radiographic Evaluation Of Accuracy Of Surgical Stent For Implant Placement In Knife Edge Posterior Mandibular Ridge In Cases Of Ridge Splitting, Fardos N. Rizk, Engy Abdelhamed
Dentistry
Aim: This study was conducted to evaluate the efficacy of using conventional surgical stents guided by cone beam computed tomography in determining the position and buccolingual inclination of implants placed in posterior mandibular knife edge ridge in cases of ridge splitting with and without bone grafting material. Materials and Methods: The study was conducted on sixteen implants placed bilaterally in posterior knife edge mandibular ridge of four patients, where each patient received four implants in the form of two in each side. Implants on the right side of the ridge were placed following ridge splitting and bone grafting (group A). …

Background: Multipotential precursor cell lines derived from human bone marrow, capable of differentiating into cartilage or bone, may provide a useful tissue development model for studying the regulation and metabolism of putative growth and differentiation factors necessary for tissue regeneration. In mammals, the process of bone development depends on the proliferation and differentiation of osteoblast lineage cells, and the subsequent synthesis and mineralization of bone extracellular matrix (ECM). Vitamin D metabolites play a pivotal role in bone and mineral homeostasis, and are positive factors on bone development. Recently, it was demonstrated that a human-derived engineered osteoblast precursor cell line (OPC1), …
Effect Of Two Different Attachments On The Supporting Structures And Masticatory Capacity Of Implant Retained Mandibular Overdenture, Fardos N. Rizk
Effect Of Two Different Attachments On The Supporting Structures And Masticatory Capacity Of Implant Retained Mandibular Overdenture, Fardos N. Rizk
Dentistry
Aim: This study was conducted to compare the effect of ball and socket attachment and GPS attachment in implant retained mandibular overdenture cases regarding changes in: crestal bone height and density surrounding implants, electromyographic activity of temporalis and masseter muscles and occlusal biting force. Materials and Methods: Following two stage surgical protocol twelve completely edentulous patients received two implants placed bilaterally in the canine region (24 implants) to retain mandibular overdenture. Four months following the surgery patients were randomly divided into two equal groups; Group-I received ball and socket attachment while Group-II received GPS attachment upon which mandibular overdentures were …
Comparison Of Occlusal Plane Orientation Obtained Using Five Facebow Systems, Thomas C. Maveli
Comparison Of Occlusal Plane Orientation Obtained Using Five Facebow Systems, Thomas C. Maveli
Loma Linda University Electronic Theses, Dissertations & Projects
PURPOSE: An in vitro investigation analyzing the sagittal and coronal orientation of the occlusal plane using five different facebow transfer systems. MATERIALS AND METHODS: A phantom head containing a maxillary typodont (the control) was oriented so that Frankfort Horizontal Plane (FHP) corresponds with the horizon. The angle between the occlusal plane of the maxillary arch of the phantom head and the FHP was measured along the sagittal and coronal planes using a digital protractor. Fifteen Facebow records using each of 5 facebow transfer systems (the test groups) were made on the phantom head containing the maxillary typodont. Diagnostic casts of …
