Self-Ligating Brackets in Orthodontics

The Angle Orthodontist, 2010
To evaluate the clinical differences in relation to the use of self-ligating brackets in orthodontics.Electronic databases were searched; no restrictions relating to publication status or language of publication were applied. Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) investigating the influence of bracket type on ...

Effect of Biomechanical Properties of Perioral Soft Tissues on Lip Response to Simulated Protraction of Upper Front Teeth

Journal of Oral Rehabilitation, Volume 52, Issue 5, Page 632-640, May 2025.
ABSTRACT Background Proclination of front teeth in orthodontics and oral rehabilitation may influence lip protrusion and the overall facial profile. We hypothesized that the degree of profile changes is determined by the biomechanical properties of the lips. Objectives (1) to investigate the upper lip changes induced by a simulated protraction of upper

In vitro evaluation of microleakage under orthodontic brackets bonded with different adhesive systems

European Journal of Dentistry, 2017
Objective: Adhesives systems have a drawback when utilized for bonding orthodontic brackets: they shrink during photopolymerization creating microleakage.

Courant brackets on noncommutative algebras and omni-Lie algebras [PDF]

arXiv, 2006
We define a Courant bracket on an associative algebra using the theory of Hochschild homology, and we introduce the notion of Dirac algebra. We show that the bracket of an omni-Lie algebra is quite a kind of Courant bracket.

Fluoridated elastomers: Effect on the microbiology of plaque [PDF]

, 2004
The objective of this study was to investigate the effect of fluoridated elastomeric ligatures on the microbiology of local dental plaque in vivo. This randomized, prospective, longitudinal, clinical trial had a split-mouth crossover design. The subjects

Fluoride-Releasing Materials to Prevent White Spot Lesions around Orthodontic Brackets: A Systematic Review.

Brazilian Dental Journal, 2016
The relation between orthodontic fixed appliances use and enamel demineralization is well established. Different preventive approaches have been suggested to this problem, but controversy remains about which is the best.

In vitro determination of genotoxicity and cytotoxicity induced by stainless steel brackets with and without surface coating in cultures of oral mucosal cells

BMC Oral Health
Background Orthodontics is a speciality of dentistry that uses a plethora of devices made from myriad materials to manage various malocclusions. Prolonged contact of orthodontic appliances with oral tissues can lead to cellular damage, highlighting the ...

Computational Orthodontic Force Simulation: A Review [PDF]

arXiv
In orthodontic treatment, the biological response of the tooth, periodontal ligament, and bone complex to orthodontic force is crucial in influencing treatment outcomes. The challenge lies in accurately measuring, estimating, and predicting these forces during clinical procedures.

Non-equal-time Poisson brackets [PDF]

arXiv, 1998
The standard definition of the Poisson brackets is generalized to the non-equal-time Poisson brackets. Their relationship to the equal-time Poisson brackets, as well as to the equal- and non-equal-time commutators, is discussed.
