Background Desirable molar distalization by bodily movement is challenging and can be difficult to achieve. This study investigated changes in molar angulation (mesiodistal tipping), molar inclination (buccolingual torque) and rotation during distalization using clear aligner therapy (CAT). Materials and methods This retrospective study included 3...

Background This study aimed to assess the correlation between maxillary sinus proximity to root apices of maxillary molars and root resorption during molar distalization using clear aligner therapy (CAT). Materials and methods Thirty-eight cone beam computed tomography scans (CBCTs) obtained pre- (T0) and post-treatment (T1) from 19 adult patients...
Article
Objectives: To investigate the post-treatment stability of anterior open bite (AOB) cases treated with upper and lower extrusion arches in adults. Materials and methods: 23 patients with AOB were treated with extrusion arches and evaluated for dentoskeletal changes using lateral cephalometric radiographs before treatment (T0), after treatment (T...

Objective To quantify dentoskeletal changes accompanying the use of extrusion arches during the treatment of anterior open bite (AOB) in adults. Materials and Methods A total of 23 adult patients with an AOB of −3.05 mm ± 1.27 mm were treated with upper and lower extrusion arches after the alignment phase. Lateral cephalograms were taken before pl...
Article
Introduction The effects on offspring craniofacial bone morphology and accretion because of altered maternal exposure to dietary components such as calcium (Ca) and phosphorus (P) are unclear. The objective of this study was to investigate the changes in offspring skull morphology and tissue mineral density (TMD), including sex-specific changes, wi...

Background and Objectives: The aim of this systematic review was to review the effect of different activation protocols of miniscrew-assisted palatal expanders used in the treatment of maxillary skeletal transverse deficiency. Material and methods: A search was conducted in MEDLINE via PubMed, Web of Science, Scopus, Cochrane Library till May 2020....

The aim of this review was to evaluate the current evidence regarding post-treatment effects of tooth-bone-borne vs. bone-borne expanders. A search was conducted in MEDLINE via PubMed, Web of Science, Scopus, Cochrane Library, Google Scholar, and Open Gray; in addition to a hand search in reference lists of selected articles and creating a search a...

This study aimed to evaluate and compare the dentoalveolar effects of the myofunctional trainer T4KTM versus twin block in children with class II division I malocclusion. Two parallel arm randomized comparative clinical trial was conducted, including twenty healthy children, 9–12 years old, showing Angle’s class II division I malocclusion due to ma...

Abstract Introduction: Orthodontic adhesives routinely used for bracket bonding can have a major contribution in enhancement of bacterial biofilm. Objective: A systematic review was conducted to find out whether incorporating antimicrobial silver nanoparticles (AgNPs) into orthodontic bonding system affects its shear bond strength (SBS). Materials...
Article
Objectives The purpose of our study was to determine morphological changes and bone mineral density (BMD) differences in the adult mandible of offspring exposed to high calcium, low phosphorus diets in utero until weaning age. Materials and Methods Time‐mated FVB wild‐type mice were fed normal or experimental diet during gestation and until weanin...

We investigated the effect of different force magnitudes on osteocyte apoptosis in a model of orthodontic tooth movement. Forty-nine male Sprague Dawley rats (7–9 wk of age) were divided into light- and heavy-force groups (n = 21 each group) and a control group (n = 7). A coil spring delivered pressure (either 10–15 g or 20–25 g) to the left maxill...
Article
Background The aim of this study was to compare the effect of three recycling methods: conventional aluminum oxide sandblasting combined with silane, tribochemical silica combined with silane and heat application combined with silane, or the shear bond strength of rebonded ceramic brackets compared with newly bonded brackets. Methods Sixty mechani...

Objective: To investigate the time course of osteocyte apoptosis in a rat model of orthodontic tooth movement as revealed by the caspase-3 activation pathway. Materials and Methods: Fifteen male Sprague Dawley rats (6–9weeks old) were loaded with an orthodontic appliance. A spring delivering 10–12 g of force was placed between the maxillary first m...
Conference Paper
Many factors that regulate development of the cranioskeleton also may contribute to the development of Class III malocclusion. MicroCT imaging offers a means to both qualitative and quantitative assess cranioskeletal phenotypes in three dimensions (3D). 3D imaging allows recording of craniofacial landmark coordinates that can subsequently be employ...
