Effects of stress relaxation in beta-titanium cantilevers used in orthodontic mechanics.

Objective: This study evaluated the force decay and design shape changes caused by stress relaxation in two different orthodontic cantilever configurations.

Methods: Eighty cantilevers made of 0.017 x 0.

Can we expect similar behavior among CuNiTi 35°C wires?

Objective: This paper aims to verify the thermodynamic, mechanical and chemical properties of CuNiTi 35ºC commercial wires.

Methods: Forty pre-contoured copper-nickel-titanium thermodynamic 0.017 x 0.

Importance of orthodontic intervention of the Class III malocclusion in mixed dentition.

Introduction: Supervising the development of occlusion, managing problems during the transition from mixed to permanent dentition, as well as controlling environmental factors that contribute to establishing malocclusion, are important actions to achieve a Class I occlusion with facial balance. Among these problems, the malocclusions associated with dysfunctions such as mouth breathing or obstructive sleep apnea syndrome (OSAS), atypical swallowing and abnormal tongue position, open bites, crossbites and maxillomandibular discrepancies, and especially the Class III malocclusion can be listed.

Objective: The purpose of this article is to present and discuss the main aspects relevant to the benefits of performing the treatment of Class III malocclusion in patients with growth.

Influence of temperature and humidity on the long-term storage of latex and non-latex orthodontic elastics.

Objectives: The objective of this study was to evaluate the influence of long-term storage on latex and non-latex orthodontic elastics.

Materials And Methods: The sample consisted of 300 orthodontic elastics, 150 latex and 150 non-latex (American Orthodontics *(AO) and Morelli) of medium force and a standard size of 3/16'' divided into 20 groups, 10 for each manufacturer, with 15 specimens each. The groups (G1*-G10* and G1-G10) were made up based on the manufacturer, storage temperature (ambient and refrigerated), material, and ambient humidity (exposed and non-exposed).
