Comparison of two micro-osteoperforation protocols using mini-screws on the rate and type of extraction space closure: A randomized clinical trial

open access: yesDental Research Journal
Background: Accelerating orthodontic space closure while minimizing anchorage loss remains a clinical priority. Micro-osteoperforation (MOP) has emerged as a minimally invasive technique to enhance tooth movement.

Penutupan Ruang Pasca Pencabutan pada Perawatan Ortodonti

open access: yesJournal of Dentistry Indonesia, 2015
Orthodontic space closure of every single patient should be planned individually based on the diagnosis and treatment plan. Failure on this procedure due to anchorage loss will inhibit correction of the bimaxillary protrusion because mesial movement of ...

A Category of Discrete Closure Spaces

open access: yes, 2005
Discrete systems such as sets, monoids, groups are familiar categories. The internal strucutre of the latter two is defined by an algebraic operator. In this paper we describe the internal structure of the base set by a closure operator. We illustrate the role of such closure in convex geometries and partially ordered sets and thus suggestthe ...

The closure of derivative average radial integrable spaces in the Bloch space

open access: yesJournal of Inequalities and Applications
A description of the closure in the Bloch space of the Bloch functions that are in the derivative average radial integrable space is given. As a byproduct, we get some new characterizations for the Bloch space B $\mathcal{B}$ , the little Bloch space B 0

Fuzzy closure spaces

open access: yesJournal of Mathematical Analysis and Applications, 1985
The authors study a fuzzy analogue of the closure spaces introduced by \textit{E. Čech} [Topological spaces (1966); pp. 237-241]. Here a closure operator need not be idempotent. The authors note the relation between fuzzy closure spaces and fuzzy topologies, construct closures for products and disjoint unions, and introduce weak versions of continuity ...

P*-closure operator and p*-regularity in fuzzy setting [PDF]

open access: yesMathematica Moravica, 2015
In this paper a new type of fuzzy regularity, viz. fuzzy p*- regularity has been introduced and studied by a newly defined closure operator, viz., fuzzy p*-closure operator.

A model of quotient spaces

open access: yesTopological Algebra and its Applications, 2017
Let R be an open equivalence relation on a topological space E. We define on E a new equivalence relation ̃ℜ̅ by x̃ ̃ℜ̅y if the closure of the R-trajectory of x is equal to the closure of the R-trajectory of y.

On Bisimilarity for Quasi-discrete Closure Spaces

open access: yesLogical Methods in Computer Science
Closure spaces, a generalisation of topological spaces, have shown to be a convenient theoretical framework for spatial model checking. The closure operator of closure spaces and quasi-discrete closure spaces induces a notion of neighborhood akin to that of topological spaces that build on open sets. For closure models and quasi-discrete closure models,

Frictionless segmented mechanics for controlled space closure

open access: yesDental Press Journal of Orthodontics
Extraction spaces may be needed to achieve specific orthodontic goals of positioning the dentition in harmony with the craniofacial complex. However, the fundamental reality that determines the occlusion final position is the control exerted by the ...

Skeletal Anchorage-Assisted Space Closure in a Patient with Bilateral Peg-Shaped Maxillary Lateral Incisors and Severe Crowding

open access: yesOral
Background: Peg-shaped maxillary lateral incisors are among the most common developmental anomalies affecting the anterior dentition and are frequently associated with Bolton tooth-size discrepancies and severe crowding.
