Characterization of Lithia‐Based Machinable Glass‐Ceramic Materials

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Lithia‐based glass ceramics lead the indirect single‐unit restoration market, but the underlying evidence is dominated by a single material. New materials have been introduced. The purpose was to investigate the elemental composition, elemental oxide composition, as‐fabricated surface morphology, as‐fabricated flexural strength ...

The metal content of generic orthodontic brackets compared with proprietary brackets

Australasian Orthodontic Journal, 2018
With minimal manufacturer information, a variety of ‘generic’ orthodontic brackets are available online from overseas distributors. The present study investigated the metal composition of generic orthodontic brackets compared with two well-known ...

Impact of Phosphoric Acid Etching Duration on the Bonding Performance of Universal Adhesives on Enamel: A Systematic Review of Laboratory Studies

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The optimal duration of phosphoric acid etching (PAE) for enamel bonding remains uncertain, particularly in the context of universal adhesives. The aim of this systematic review was to determine whether shortened etching times (< 15 s) provide comparable bond strength to conventional protocols.

The Effect of Preheating, Resin‐Based Composite, and Wire Types of Orthodontic Lingual Fixed Retainers on the Load at Failure: A Comparative In‐Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Background Preheating resin‐based composites (RBC) has been shown to enhance their mechanical and bonding properties. Nevertheless, the effect of preheating RBCs on the performance of orthodontic lingual fixed retainers has been scarcely reported.

Long-term antimicrobial assessment of orthodontic brackets coated with nitrogen-doped titanium dioxide against Streptococcus mutans

Progress in Orthodontics, 2018
Background The antimicrobial properties of orthodontic wire and brackets with nitrogen-doped titanium dioxide (N-doped TiO2) coating have been studied in the past. However, the evaluation period had been short and limited to 30 days.

Effect of artificial aging and different surface finishing protocols on the flexural strength and surface hardness of a photopolymer for manufacturing monolithic polychromatic complete dentures using PolyJet 3D printing

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated the effect of thermocycling and three different surface finishing protocols on the flexural strength and surface hardness of a novel photopolymer intended for manufacturing monolithic polychromatic dental prostheses using PolyJet 3D printing.

In vitro wearing away of orthodontic brackets and wires in different conditions: A review

Heliyon, 2022
Introduction: The release of metallic ions from orthodontic brackets and wires typically depends on their quality (chemical composition) and the medium to which they are exposed, e.g., acidic, alkaline, substances with a high fluoride concentration, etc.

In Vitro Aligners Force Analysis in the Maxillary Arch During En‐Masse Retraction With Different Attachment Positions

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to analyse the three‐dimensional forces acting on maxillary teeth with aligners activation of en‐masse retraction based on the different attachment positions in vitro. Methods Three groups were designed for the same 0.25 mm en‐masse retraction forces with three different attachment positions.

Comparison of surface topography changes from conventional metal brackets and self-ligating metal brackets after immersion in three different mouthwashes using atomic force microscopy: An in vitro study

Journal of Pharmacy and Bioallied Sciences, 2023
In orthodontics, the surface roughness and corrosion behavior due to metal ion releases in orthodontic brackets and archwires affect the effectiveness of tooth movement. Atomic force microscopy (AFM) can provide three-dimensional information measurements
