Reinforcement of Denture Base Resins

Iranian Journal of Public Health, 2005
Introduction: PMMA has been the most popular denture base material because of its advantages including good aesthetics, accurate fit, stability in the oral environment, easy laboratory and clinical manipulation and inexpensive equipments since the 1930’s. However, its fracture resistance is not satisfactory. Aim: The aim of this study is to improve the

Assessing the influence of titanium dioxide nanotubes incorporation on thermal and thermomechanical characteristics of 3D‐printed denture base resin

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aims to evaluate the effects of adding titanium dioxide (TiO2) nanotubes (NTs) to three‐dimensional (3D) printed denture base resin on the thermal and thermomechanical properties, which have high clinical relevance. Materials and Methods TiO2 NTs with dimensions of 30–70 nm in diameter and 2–4 µm in length were added to the ...

The effect of glutaraldehyde base disinfectants on denture base resins

The Journal of Prosthetic Dentistry, 1989
The effect of two alkaline glutaraldehyde base disinfectants on a heat-cured denture base resin was evaluated by the flexural strength, the repair flexural strength, and the surface morphology of the material that had been immersed up to 12 hours in the disinfecting solutions.

Flexural strength and surface hardness of nanocomposite denture base resins

Heliyon
Purpose: Higher bending forces during chewing and occlusal loading can lead to the deformation of denture bases. Roughness and microbial adhesion can be the result of improper care of the denture. Many attempts have been made to improve the properties of

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...
