Objective(s): The aim of this study was to synthesis new dental nanocomposites reinforced with fabricated glass nanoparticles and compare two methods for fabrication and investigate the effect of this filler on mechanical properties. Materials and Methods: The glass nanoparticles were produced by wet milling process. The particle size and shape was achieved using PSA and SEM. Glass nanoparticle...

BACKGROUND Compared with titanium (Ti) and other metal implant materials, poly(ether-ether ketone) (PEEK) shows outstanding biomechanical properties. A number of studies have also reported attractive bioactivity for nano-TiO(2) (n-TiO(2)). METHODS In this study, n-TiO(2)/PEEK nanocomposites were prepared, taking advantage of the unique properties of both PEEK polymer and n-TiO(2). The in vitr...

BACKGROUND In daily clinical practice, esthetics of anterior teeth is a common presenting complaint of patients. OBJECTIVE This case report discusses the management of asymmetric smile associated with unsatisfactory extensive composite restorations and describes a clinical protocol using the direct composite resin for smile enhancement to restore the dental harmony of anterior teeth. METHOD...

This review paper is about development and evolution of nanocomposites to smart materials. With the idea formulating dental materials with long lasting maintenance functionality, it important incorporate certain features such as polymer nanofibers, natural fibers, clay, nanoclays, metal oxides, carbon nano fillers, metallic particles sulphides different ions. Therefore, helps deal both external...

Organic-inorganic hybrid materials, such as polyhedral oligomeric silsesquioxanes (POSS), have the potential to improve the mechanical properties of the methacrylate-based composites and resins used in dentistry. In this article, nanocomposites of methacryl isobutyl POSS (MI-POSS [bears only one methacrylate functional group]) and methacryl POSS (MA-POSS [bears eight methacrylate functional gro...

BACKGROUND The aim of this study was to analyze the bond strength of aged resin based nanocomposites repaired with the same and bulk fill composites. MATERIAL AND METHODS Seventy-two disc shaped resin composites consisted of three different nanocomposite resins (Filtek Ultimate/FU, Herculite XRV Ultra/HXRV, and Reflectys/R) were produced. After storing the samples for 8 weeks in distilled wat...
