Phonetics plays a major role in the fabrication of prostheses. This study aimed to assess the knowledge of students regarding the role of phonetics in denture fabrication and to improve the educational process and the clinical application. The study was conducted at the College of Dentistry, Imam Abdulrahman Bin Faisal University, and involved a survey of 344 dental students and interns.

This study aimed to evaluate the effect of alumina-blasting, silane coupling agent, and thermal cycling on the shear bond strength of repaired teeth to denture base.
Materials And Methods: Specimens (140) of repaired teeth to denture bases were fabricated and divided into 14 groups: 7 groups before thermal cycling and 7 groups after thermal cycling ( = 10).
Article Synopsis
- - The study aimed to investigate how adding nano-silicon dioxide (nano-SiO) affects the flexural strength (FS) of repaired acrylic denture bases, using various concentrations of nano-SiO in the repair resin.
- - Specimens were created with two different joint designs (butt and bevel) and tested for FS using a three-point bending test, with results analyzed statistically to assess the differences between the groups.
- - Results showed that the nano-SiO addition significantly enhanced the FS of the acrylic resin, especially in beveled joints, while a homogenous distribution of the additive was observed under SEM, indicating improved performance compared to unmodified groups.
Purpose: To evaluate and compare the effects of glass fiber (GF), Zirconium oxide nanoparticles (nano-ZrO ), and silicon dioxide nanoparticles (nano-SiO ) addition on the flexural strength and impact strength of repaired denture base material.
Materials And Methods: Heat-polymerized acrylic resin specimens were fabricated. All specimens were sectioned centrally and beveled creating 2.
Purpose: To evaluate the combined effect of mechanical surface treatment with intermediate bonding agents (methyl methacrylate [MMA] and silane coupling agents) and ZrO nanoparticle (nano-ZrO ) addition to repair material on the shear bond strength (SBS) of repaired denture bases.
Materials And Methods: Heat-polymerized acrylic resin was used to fabricate 130 cylindrical blocks (15 mm × 10 mm) and divided into a control group without treatment (C, n = 10), and 3 repair groups (n = 40/group) divided into specimens treated with alumina blasting alone (AB), specimens blasted with alumina combined with silane coupling agent (AB + SCA), or combined with MMA-based composite bonding agent (AB + MA). Treated groups were further subdivided according to nano-ZrO concentrations into 0 wt%, 2.
