To evaluate and compare the effects of glass fiber (GF), Zirconium oxide nanoparticles (nano-ZrO2 ), silicon dioxide (nano-SiO2 ) addition on flexural strength impact repaired denture base material.Heat-polymerized acrylic resin specimens were fabricated. All sectioned centrally beveled creating 2.5 mm repair gap except for 10 controls. Specimen grouping (n = 10/group) was done according to filler concentration 0%, 0.25%, 0.5%, 0.75% auto-polymerized powder. Modified mixed, packed in gap,...
The objective of this study was to evaluate the effect nano-SiO2 addition on flexural strength (FS) repaired acrylic denture base. Heat-polymerized resin specimens were fabricated in dimensions (65 × 10 2.5 ± 0.1 mm3 ) and then sectioned prepared, creating repair gap with butt (90 degrees) bevel (45 surface designs forming two main groups according joint design. Further subdivision done into four (n = 10) concentration: one unmodified group three modified (0.25, 0.5, 0.75 wt %)...
Abstract Purpose To evaluate the combined effect of mechanical surface treatment with intermediate bonding agents (methyl methacrylate [MMA] and silane coupling agents) ZrO 2 nanoparticle (nano‐ZrO ) addition to repair material on shear bond strength (SBS) repaired denture bases. Materials Methods Heat‐polymerized acrylic resin was used fabricate 130 cylindrical blocks (15 mm × 10 mm) divided into a control group without (C, n = 10), 3 groups (n 40/group) specimens treated alumina blasting...
Detachment of acrylic teeth from denture base material is a common complication in dentistry which accounts for 26-30% repair cases. This study aimed to evaluate the effect alumina-blasting, silane coupling agent, and thermal cycling on shear bond strength repaired base.Specimens (140) bases were fabricated divided into 14 groups: 7 groups before after (n = 10). The according surface treatment no (control), (B), tooth (T), or both (BT). Each group was further subdivided method...
The aim of this in vitro study was to evaluate the effects different durations silane coupling agent application compared a universal adhesive system regarding shear bond strength two ceramic materials.A total 120 human molars were ground dentinal coronal third and then fixed into an acrylic resin holder. Lithium disilicate specimens divided main groups according type: computer-aided design/computer-aided manufacturing IPS e.max CAD heat-pressed Initial LiSi Press GC (dimensions 4 × 3× 3...
Phonetics plays a major role in the fabrication of prostheses. This study aimed to assess knowledge students regarding phonetics denture and improve educational process clinical application. The was conducted at College Dentistry, Imam Abdulrahman Bin Faisal University, involved survey 344 dental interns. questionnaire contained 20 questions divided into three sections: general knowledge, correlations, evaluations. data were collected analyzed statistically using independent t-tests, one-way...
