Three-dimensional deformation of orthodontic brackets [PDF]

Journal of Dental Biomechanics, 2013
Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine this wire–bracket interaction.

Diagnosis and Dentists' Treatment Preferences for Vestibular Enamel Defects—A Cross‐Sectional Survey

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives Vestibular enamel defects, including WSL, MIH, or fluorosis, can impair esthetics and patient well‐being, making accurate diagnosis essential for selecting appropriate treatment strategies. However, distinguishing these based solely on clinical images—an increasingly common scenario in digital communication—can be challenging.

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.
